Welcome to Edition 8.26 of the Rocket Report! The past week has been one of advancements and setbacks in the rocket business. NASA rolled the massive rocket for the Artemis II mission to its launch pad in Florida, while Chinese launchers suffered back-to-back failures within a span of approximately 12 hours. Rocket Lab’s march toward a debut of its new Neutron launch vehicle in the coming months may have stalled after a failure during a key qualification test. We cover all this and more in this week’s Rocket Report.

Australia invests in sovereign launch. Six months after its first orbital rocket cleared the launch tower for just 14 seconds before crashing back to Earth, Gilmour Space Technologies has secured 217 million Australian dollars ($148 million) in funding that CEO Adam Gilmour says finally gives Australia a fighting chance in the global space race, the Sydney Morning Herald reports. The funding round, led by the federal government’s National Reconstruction Fund Corporation and superannuation giant Hostplus with $75 million each, makes the Queensland company Australia’s newest unicorn—a fast-growth start-up valued at more than $1 billion—and one of the country’s most heavily backed private technology ventures.

Homegrown rocket… “We’re a rocket company that has never had access to the capital that our American competitors have,” Gilmour told the newspaper. “This is the first raise where I’ve actually raised a decent amount of capital compared to the rest of the world.” The investment reflects growing concern about Australia’s reliance on foreign launch providers—predominantly Elon Musk’s SpaceX—to put government, defense, and commercial satellites into orbit. With US launch queues stretching beyond two years and geopolitical tensions reshaping access to space infrastructure, Canberra has identified sovereign launch capability as a strategic priority. Gilmour’s first Eris rocket lifted off from the Bowen Orbital Spaceport in North Queensland on July 30 last year. It achieved 14 seconds of flight before falling back to the ground, a result Gilmour framed as a partial success in an industry where first launches routinely fail.

Isar Aerospace postpones test flight. Isar Aerospace scrubbed a potential January 21 launch of its Spectrum rocket to address a technical fault, Aviation Week & Space Technology reports. Hours before the launch window was set to open, the German company said that it was addressing “an issue with a pressurization valve.” A valve issue was one of the factors that caused a Spectrum to crash moments after liftoff on Isar’s first test flight last year. “The teams are currently assessing the next possible launch opportunities and a new target date will be announced shortly,” the company wrote in a post on its website. The Spectrum rocket, designed to haul cargoes of up to a metric ton (2,200 pounds) to low-Earth orbit, is awaiting liftoff from Andøya Spaceport in Norway.

Geopolitics at play... The second launch of Isar’s Spectrum rocket comes at a time when Europe’s space industry looks to secure the continent’s sovereignty in spaceflight. European satellites are no longer able to launch on Russian rockets, and the continent’s leaders don’t have much of an appetite to turn to US rockets amid strained trans-Atlantic relations. Europe’s satellite industry is looking for more competition for the Ariane 6 and Vega C rockets developed by ArianeGroup and Avio, and Isar Aerospace appears to be best positioned to become a new entrant in the European launch market. “I’m well aware that it would be really good for us Europeans to get this one right,” said Daniel Metzler, Isar’s co-founder and CEO.

A potential buyer for Orbex? UK-based rocket builder Orbex has signed a letter of intent to sell its business to European space logistics startup The Exploration Company, European Spaceflight reports. Orbex was founded in 2015 and is developing a small launch vehicle called Prime. The company also began work on a larger medium-lift launch vehicle called Proxima in December 2024. On Wednesday, Orbex published a brief press release stating that a letter of intent had been signed and that negotiations had begun. The company added that all details about the transaction remain confidential at this stage.

Time’s up... A statement from Orbex CEO Phil Chambers suggests that the company’s financial position factored into its decision to pursue a buyer. “Our Series D fundraising could have led us in many directions,” said Chambers. “We believe this opportunity plays to the strengths of both businesses, and we look forward to sharing more when the time is right.” The Exploration Company, headquartered near Munich, Germany, is developing a reusable space capsule to ferry cargo to low-Earth orbit and a high-thrust reusable rocket engine. It is one of the most well-financed space startups in Europe. Orbex is one of five launch startups in Europe selected by the European Space Agency last year to compete in the European Launcher Challenge and receive funding from ESA member states. But the UK company’s financial standing is in question. Orbex’s Danish subsidiary is filing for bankruptcy, and its main UK entity is overdue in filing its 2024 financial accounts. (submitted by EllPeaTea)

A bad day for Chinese rockets. China suffered a pair of launch failures January 16, seeing the loss of a classified Shijian satellite and the failed first launch of the Ceres-2 rocket, Space News reports. The first of the two failures involved the attempted launch of a Shijian military satellite aboard a Long March 3B rocket from the Xichang launch base in southwestern China. The Shijian 32 satellite was likely heading for a geostationary transfer orbit, but a failure of the Long March 3B’s third stage doomed the mission. The Long March 3B is one of China’s most-flown rockets, and this was the first failure of a Long March 3-series vehicle since 2020, ending a streak of 50 consecutive successful flights of the rocket.

And then… Less than 12 hours later, another Chinese rocket failed on its climb to orbit. This launch, using a Ceres-2 rocket, originated from the Jiuquan space center in northwestern China. It was the first flight of the Ceres-2, a larger variant of the light-class Ceres-1 rocket developed and operated by a Chinese commercial startup named Galactic Energy. Chinese officials did not disclose the payloads lost on the Ceres-2 rocket.

Neutron in neutral. Rocket Lab suffered a structural failure of the Neutron rocket’s Stage 1 tank during testing, setting back efforts to get to the inaugural flight for the partially reusable launcher, Aviation Week & Space Technology reports. The mishap occurred during a hydrostatic pressure trial, the company said Wednesday. “There was no significant damage to the test structure or facilities,” Rocket Lab added. Rocket Lab last year pushed the first Neutron mission from 2025 to 2026, citing the volume of testing ahead. The US-based company said it is now analyzing what transpired to determine the impact on Neutron launch plans. Rocket Lab said it would provide an update during its next quarterly financials, due in a few weeks.

Where to go from here?… The Neutron rocket is designed to catapult Rocket Lab into more direct competition with legacy rocket companies like SpaceX and United Launch Alliance. “The next Stage 1 tank is already in production, and Neutron’s development campaign continues,” the company said. Setbacks like this one are to be expected during the development of new rockets. Rocket Lab has publicized aggressive, or aspirational, launch schedules for the first Neutron rocket, so it’s likely the company will hang onto its projection of a debut launch in 2026, at least for now.

Falcon 9 launches NRO spysats. SpaceX executed a late night Falcon 9 launch from Vandenberg Space Force Base on January 16, carrying an undisclosed number of intelligence-gathering satellites for the National Reconnaissance Office, Spaceflight Now reports. The mission, NROL-105, hauled a payload of satellites heading to low-Earth orbit, which are believed to be Starshield, a government variant of the Starlink satellites. “Today’s mission is the twelfth overall launch of the NRO’s proliferated architecture and first of approximately a dozen NRO launches scheduled throughout 2026 consisting of proliferated and national security missions,” the NRO said in a post-launch statement.

Mysteries abound… A public accounting of the agency’s proliferated constellation suggests it now numbers nearly 200 satellites with the ability to rapidly image locations around the world. The NRO has dozens more satellites serving other functions. “Having hundreds of NRO satellites on orbit is critical to supporting our nation and its partners,” the agency said in a statement. “This growing constellation enhances mission resilience and capability through reduced revisit times, improved persistent coverage, and accelerated processing and delivery of critical data.” What was unusual about the January 16 mission is it may have only carried two satellites, well short of the 20-plus Starshield satellites launched on most previous Falcon 9 launches, according to Jonathan McDowell, an astrophysicist and expert tracker of global space launch activity.

Long March 12B hot-fired at Jiuquan. China’s main space contractor performed a static fire test of a new reusable Long March rocket Friday, paving the way for a test flight, Space News reports. The test-firing of the Long March 12B rocket’s first stage engines occurred on a launch pad at the Dongfeng Commercial Space Innovation Test Zone at Jiuquan spaceport in northwestern China. The mere existence of the Long March 12B rocket was not publicly known until recently. The new rocket was developed by a subsidiary of the state-owned China Aerospace Science Technology Corporation, with the capacity to carry a payload of 20 metric tons to low-Earth orbit in expendable mode. It’s unknown if the first Long March 12B test flight will include a booster landing attempt.

Another one… The Long March 12B has a reusable first stage with landing legs, similar to the recovery architecture of SpaceX’s Falcon 9 rocket. The booster is designed to land downrange at a recovery zone in the Gobi Desert. The Long March 12B is the latest in a line of partially reusable Chinese rockets to reach the launch pad, following soon after the debut launches of the Long March 12A and Zhuque 3 rocket last month. Several more companies in China are working on their own reusable boosters. Of them all, the Long March 12B appears to be the closest to a clone of SpaceX’s Falcon 9. Like the Falcon 9, the Long March 12B will have nine kerosene-fueled first stage engines and a single kerosene-fueled upper stage engine. Chinese officials have not announced when the Long March 12B will launch.

Artemis II rolls to the launch pad. Preparations for the first human spaceflight to the Moon in more than 50 years took a big step forward last weekend with the rollout of the Artemis II rocket to its launch pad, Ars reports. The rocket reached a top speed of just 1 mph on the four-mile, 12-hour journey from the Vehicle Assembly Building to Launch Complex 39B at NASA’s Kennedy Space Center in Florida. At the end of its nearly 10-day tour through cislunar space, the Orion capsule on top of the rocket will exceed 25,000 mph as it plunges into the atmosphere to bring its four-person crew back to Earth.

Key test ahead… “This is the start of a very long journey,” said NASA Administrator Jared Isaacman. “We ended our last human exploration of the Moon on Apollo 17.” The Artemis II mission will set several notable human spaceflight records. Astronauts Reid Wiseman, Victor Glover, Christina Koch, and Jeremy Hansen will travel farther from Earth than any human in history as they travel beyond the far side of the Moon. They won’t land. That distinction will fall to the next mission in line in NASA’s Artemis program. This will be the first time astronauts have flown on the Space Launch System rocket and Orion spacecraft. The launch window opens February 6, but the exact date of Artemis II’s liftoff will be determined by the outcome of a critical fueling test of the SLS rocket scheduled for early February.

Blue Origin confirms rocket reuse plan. Blue Origin confirmed Thursday that the next launch of its New Glenn rocket will carry a large communications satellite into low-Earth orbit for AST SpaceMobile, Ars reports. The rocket will launch the next-generation Block 2 BlueBird satellite “no earlier than late February” from Launch Complex 36 at Cape Canaveral Space Force Station. However, the update from Blue Origin appears to have buried the real news toward the end: “The mission follows the successful NG-2 mission, which included the landing of the ‘Never Tell Me The Odds’ booster. The same booster is being refurbished to power NG-3,” the company said.

Impressive strides… The second New Glenn mission launched on November 13, just 10 weeks ago. If the company makes the late-February target for the next mission—and Ars was told last week to expect the launch to slip into March—it will represent a remarkably short turnaround for an orbital booster. By way of comparison, SpaceX did not attempt to refly the first Falcon 9 booster it landed in December 2015. Instead, initial tests revealed that the vehicle’s interior had been somewhat torn up. It was scrapped and inspected closely so that engineers could learn from the wear and tear.

Welcome to Edition 8.24 of the Rocket Report! We’re back from a restorative holiday, and there’s a great deal Eric and I look forward to covering in 2026. You can get a taste of what we’re expecting this year in this feature. Other storylines are also worth watching this year that didn’t make the Top 20. Will SpaceX’s Starship begin launching Starlink satellites? Will United Launch Alliance finally get its Vulcan rocket flying at a higher cadence? Will Blue Origin’s New Glenn rocket be certified by the US Space Force? I’m looking forward to learning the answers to these questions, and more. As for what has already happened in 2026, it has been a slow start on the world’s launch pads, with only a pair of SpaceX missions completed in the first week of the year. Only? Two launches in one week by any company would have been remarkable just a few years ago.

As always, we welcome reader submissions. If you don’t want to miss an issue, please subscribe using the box below (the form will not appear on AMP-enabled versions of the site). Each report will include information on small-, medium-, and heavy-lift rockets, as well as a quick look ahead at the next three launches on the calendar.

New launch records set in 2025. The number of orbital launch attempts worldwide last year surpassed the record 2024 flight rate by 25 percent, with SpaceX and China accounting for the bulk of the launch activity, Aviation Week & Space Technology reports. Including near-orbital flight tests of SpaceX’s Starship-Super Heavy launch system, the number of orbital launch attempts worldwide reached 329 last year, an annual analysis of global launch and satellite activity by Jonathan’s Space Report shows. Of those 329 attempts, 321 reached orbit or marginal orbits. In addition to five Starship-Super Heavy launches, SpaceX launched 165 Falcon 9 rockets in 2025, surpassing its 2024 record of 134 Falcon 9 and two Falcon Heavy flights. No Falcon Heavy rockets flew in 2025. US providers, including Rocket Lab Electron orbital flights from its New Zealand spaceport, added another 30 orbital launches to the 2025 tally, solidifying the US as the world leader in space launch.

International launches… China, which attempted 92 orbital launches in 2025, is second, followed by Russia, with 17 launches last year, and Europe with eight. Rounding out the 2025 orbital launch manifest were five orbital launch attempts from India, four from Japan, two from South Korea, and one each from Israel, Iran, and Australia, the analysis shows. The global launch tally has been on an upward trend since 2019, but the numbers may plateau this year. SpaceX expects to launch about the same number of Falcon 9 rockets this year as it did last year as the company prepares to ramp up the pace of Starship flights.

South Korean startup suffers launch failure. The first commercial rocket launched at Brazil’s Alcantara Space Center crashed soon after liftoff on December 22, dealing a blow to Brazilian aerospace ambitions and the South Korean satellite launch company Innospace, Reuters reports. The rocket began its vertical trajectory as planned after liftoff but fell to the ground after something went wrong 30 seconds into its flight, according to Innospace, the South Korean startup that developed the launch vehicle. The craft crashed within a pre-designated safety zone and did not harm anyone, officials said.

An unsurprising result... This was the first flight of Innospace’s nano-launcher, named Hanbit-Nano. The rocket was loaded with eight small payloads, including five deployable satellites, heading for low-Earth orbit. But rocket debuts don’t have a good track record, and Innospace’s rocket made it a bit farther than some new launch vehicles do. The rocket is designed to place up to 200 pounds (90 kilograms) of payload mass into Sun-synchronous orbit. It has a unique design, with hybrid engines consuming a mix of paraffin as the fuel and liquid oxygen as the oxidizer. Innospace said it intends to launch a second test flight in 2026. (submitted by EllPeaTea)

Take two for Germany’s Isar Aerospace. Isar Aerospace is gearing up for a second launch attempt of its light-class Spectrum rocket after completing 30-second integrated static test firings for both stages late last year, Aviation Week & Space Technology reports. The endeavor would be the first orbital launch for Spectrum and an effort at a clean mission after a March 30 flight ended in failure because a vent valve inadvertently opened soon after liftoff, causing a loss of control. “Rapid iteration is how you win in this domain. Being back on the pad less than nine months after our first test flight is proof that we can operate at the speed the world now demands,” said Daniel Metzler, co-founder and CEO of Isar Aerospace.

No earlier than… Airspace and maritime warning notices around the Spectrum rocket’s launch site in northern Norway suggest Isar Aerospace is targeting launch no earlier than January 17. Based near Munich, Isar Aerospace is Europe’s leading launch startup. Not only has Isar beat its competitors to the launch pad, the company has raised far more money than other European rocket firms. After its most recent fundraising round in June, Isar has raised more than 550 million euros ($640 million) from venture capital investors and government-backed funds. Now, Isar just needs to reach orbit.

A step forward for Canada’s launch ambitions. The Atlantic Spaceport Complex—a new launch facility being developed by the aerospace company NordSpace on the southern coast of Newfoundland—has won an important regulatory approval, NASASpaceflight.com reports. The provincial government of Newfoundland and Labrador “released” the spaceport from the environmental assessment process. “At this stage, the spaceport no longer requires further environmental assessment,” NordSpace said in a statement. “This release represents the single most significant regulatory milestone for NordSpace’s spaceport development to date, clearing the path for rapid execution of Canada’s first purpose-built, sovereign orbital launch complex designed and operated by an end-to-end launch services provider.”

Now, about that rocket... NordSpace began construction of the Atlantic Spaceport Complex last year and planned to launch its first suborbital rocket from the spaceport last August. But bad weather and technical problems kept NordSpace’s Taiga rocket grounded, and then the company had to wait for the Canadian government to reissue a launch license. NordSpace said it most recently delayed the suborbital launch until March in order to “continue our focus on advancing our orbital-scale technologies.” NordSpace is one of the companies likely to participate in a challenge sponsored by the Canadian government, which is committing 105 million Canadian dollars ($75 million) to develop a sovereign orbital launch capability.

H3 rocket falters on the way to orbit. A faulty payload fairing may have doomed Japan’s latest H3 rocket mission, with the Japanese space agency now investigating if the shield separated abnormally and crippled the vehicle in flight after lifting off on December 21, the Asahi Shimbun reports. Japan Aerospace Exploration Agency officials told a science ministry panel on December 23 they suspect an abnormal separation of the rocket’s payload fairing—a protective nose cone shield—caused a critical drop in pressure in the second-stage engine’s hydrogen tank. The second-stage engine lost thrust as it climbed into space, then failed to restart for a critical burn to boost Japan’s Michibiki 5 navigation satellite into a high-altitude orbit.

Growing pains… The H3 rocket is Japan’s flagship launch vehicle, having replaced the country’s H-IIA rocket after its retirement last year. The December launch was the seventh flight of an H3 rocket, and its second failure. While engineers home in on the rocket’s suspect payload fairing, several H3 launches planned for this year now face delays. Japanese officials already announced that the next H3 flight will be delayed from February. Japan’s space agency plans to launch a robotic mission to Mars on an H3 rocket in October. While there’s still time for officials to investigate and fix the issues that caused last month’s launch failure, the incident adds a question mark to the schedule for the Mars launch.

SpaceX opens 2026 with launch for Italy. SpaceX rang in the new year with a Falcon 9 rocket launch on January 2 from Vandenberg Space Force Base in California, Spaceflight Now reports. The payload was Italy’s Cosmo-SkyMed Second Generation Flight Model 3 (CSG-FM3) satellite, a radar surveillance satellite for dual civilian and military use. The Cosmo-SkyMed mission was the first Falcon 9 rocket flight in 16 days, the longest stretch without a SpaceX orbital launch in four years.

Poached from Europe… The CSG-FM3 satellite is the third of four second-generation Cosmo-SkyMed radar satellites ordered by the Italian government. The second and third satellites have now launched on SpaceX Falcon 9 rockets instead of their initial ride: Europe’s Vega C launcher. Italy switched the satellites to SpaceX after delays in making the Vega C rocket operational and Europe’s loss of access to Russian Soyuz rockets in the aftermath of the invasion of Ukraine. The rocket swap became a regular occurrence for European satellites in the last few years as Europe’s indigenous launch program encountered repeated delays.

Rocket deploys heaviest satellite ever launched from India. An Indian LVM3 rocket launched AST SpaceMobile’s next-generation direct-to-device BlueBird satellite December 23, kicking off the rollout of dozens of spacecraft built around the largest commercial communications antenna ever deployed in low-Earth orbit, Space News reports. At 13,450 pounds (6.1 metric tons), the BlueBird 6 satellite was the heaviest spacecraft ever launched on an Indian rocket. The LVM3 rocket released BlueBird 6 into an orbit approximately 323 miles (520 kilometers) above the Earth.

The pressure is on… BlueBird 6 is the first of AST SpaceMobile’s Block 2 satellites designed to beam Internet signals directly to smartphones. The Texas-based company is competing with SpaceX’s Starlink network in the same direct-to-cell market. Starlink has an early lead in the direct-to-device business, but AST SpaceMobile says it plans to launch between 45 and 60 satellites by the end of this year. AST’s BlueBird satellites are significantly larger than SpaceX’s Starlink platforms, with antennas unfurling in space to cover an area of 2,400 square feet (223 square meters). The competition between SpaceX and AST SpaceMobile has led to a race for spectrum access and partnerships with cell service providers.

Ars’ annual power rankings of US rocket companies. There’s been some movement near the top of our annual power rankings. It was not difficult to select the first-place company on this list. As it has every year in our rankings, SpaceX holds the top spot. Blue Origin was the biggest mover on the list, leaping from No. 4 on the list to No. 2. It was a breakthrough year for Jeff Bezos’ space company, finally shaking the notion that it was a company full of promise that could not quite deliver. Blue Origin delivered big time in 2025. On the very first launch of the massive New Glenn rocket in January, Blue Origin successfully sent a test payload into orbit. Although a landing attempt failed after New Glenn’s engines failed to re-light, it was a remarkable success. Then, in November, New Glenn sent a pair of small spacecraft on their way to Mars. This successful launch was followed by a breathtaking and inspiring landing of the rocket’s first stage on a barge.

Where’s ULA?… Rocket Lab came in at No. 3. The company had an excellent year, garnering its highest total of Electron launches and having complete mission success. Rocket Lab has now gone more than three dozen launches without a failure. Rocket Lab also continued to make progress on its medium-lift Neutron vehicle, although its debut was ultimately delayed to mid-2026, at least. United Launch Alliance slipped from No. 2 to No. 4 after launching its new Vulcan rocket just once last year, well short of the company’s goal of flying up to 10 Vulcan missions.

Rocketdyne changes hands again. If you are a student of space history or tracked the space industry before billionaires and venture capital changed it forever, you probably know the name Rocketdyne. A half-century ago, Rocketdyne manufactured almost all of the large liquid-fueled rocket engines in the United States. The Saturn V rocket that boosted astronauts toward the Moon relied on powerful engines developed by Rocketdyne, as did the Space Shuttle, the Atlas, Thor, and Delta rockets, and the US military’s earliest ballistic missiles. But Rocketdyne has lost its luster in the 21st century as it struggled to stay relevant in the emerging commercial launch industry. Now, the engine-builder is undergoing its fourth ownership change in 20 years. AE Industrial Partners, a private equity firm, announced it will purchase a controlling stake in Rocketdyne from L3Harris after less than three years of ownership, Ars reports.

Splitting up… Rocketdyne’s RS-25 engine, used on NASA’s Space Launch System rocket, is not part of the deal with AE Industrial. It will remain under the exclusive ownership of L3Harris. Rocketdyne’s work on solid-fueled propulsion, ballistic missile interceptors, tactical missiles, and other military munitions will also remain under L3Harris control. The split of the company’s space and defense segments will allow L3Harris to concentrate on Pentagon programs, the company said. So, what is AE Industrial getting in its deal with L3Harris? Aside from the Rocketdyne name, the private equity firm will have a majority stake in the production of the liquid-fueled RL10 upper-stage engine used on United Launch Alliance’s Vulcan rocket. AE Industrial’s Rocketdyne will also continue the legacy company’s work in nuclear propulsion, electric propulsion, and smaller in-space maneuvering thrusters used on satellites.

Tory Bruno has a new employer. Jeff Bezos-founded Blue Origin said on December 26 that it has hired Tory Bruno, the longtime CEO of United Launch Alliance, as president of its newly formed national security-focused unit, Reuters reports. Bruno will head the National Security Group and report to Blue Origin CEO Dave Limp, the company said in a social media post, underscoring its push to expand in US defense and intelligence launch markets. The hire brings one of the US launch industry’s most experienced executives to Blue Origin as the company works to challenge the dominance of SpaceX and win a larger share of lucrative US military and intelligence launch contracts.

11 years at ULA… The move comes days after Bruno stepped down as CEO of ULA, the Boeing-Lockheed Martin joint venture that has long dominated US national security space launches alongside Elon Musk’s SpaceX. In 11 years at ULA, Bruno oversaw the development of the Vulcan rocket, the company’s next-generation launch vehicle designed to replace its Atlas V and Delta IV rockets and secure future Pentagon contracts.

A California spaceport has room to grow. A new orbital launch site is up for grabs at Vandenberg Space Force Base in California, Spaceflight Now reports. The Department of the Air Force published a request for information from launch providers to determine the level of interest in what would become the southernmost launch complex on the Western Range. The location, which will be designated as Space Launch Complex-14 or SLC-14, is being set aside for orbital rockets in a heavy or super-heavy vertical launch class. One of the requirements listed in the RFI includes what the government calls the “highest technical maturity.” It states that for the bid from a launch provider to be taken seriously, it needs to prove that it can begin operations within approximately five years of receiving a lease for the property.

Who’s in contention?… Multiple US launch providers have rockets in the heavy to super-heavy classification either currently launching or in development. Given all the requirements and the state of play on the orbital launch front, one of the contenders would likely be SpaceX’s Starship-Super Heavy rocket. The company is slated to launch the latest iteration of the rocket, dubbed Version 3, sometime in early 2026. Blue Origin is another likely contender for the prospective launch site. Blue Origin currently has an undeveloped space at Vandenberg’s SLC-9 for its New Glenn rocket. But the company unveiled plans in November for a new super-heavy lift version called New Glenn 9×4.

Welcome to Edition 8.21 of the Rocket Report! We’re back after the Thanksgiving holiday with more launch news. Most of the big stories over the last couple of weeks came from abroad. Russian rockets and launch pads didn’t fare so well. China’s launch industry celebrated several key missions. SpaceX was busy, too, with seven launches over the last two weeks, six of them carrying more Starlink Internet satellites into orbit. We expect between 15 and 20 more orbital launch attempts worldwide before the end of the year.

Another Sarmat failure. A Russian intercontinental ballistic missile (ICBM) fired from an underground silo on the country’s southern steppe on November 28 on a scheduled test to deliver a dummy warhead to a remote impact zone nearly 4,000 miles away. The missile didn’t even make it 4,000 feet, Ars reports. Russia’s military has been silent on the accident, but the missile’s crash was seen and heard for miles around the Dombarovsky air base in Orenburg Oblast near the Russian-Kazakh border. A video posted by the Russian blog site MilitaryRussia.ru on Telegram and widely shared on other social media platforms showed the missile veering off course immediately after launch before cartwheeling upside down, losing power, and then crashing a short distance from the launch site.

An unenviable track record … Analysts say the circumstances of the launch suggest it was likely a test of Russia’s RS-28 Sarmat missile, a weapon designed to reach targets more than 11,000 miles (18,000 kilometers) away, making it the world’s longest-range missile. The Sarmat missile is Russia’s next-generation heavy-duty ICBM, capable of carrying a payload of up to 10 large nuclear warheads, a combination of warheads and countermeasures, or hypersonic boost-glide vehicles, according to the Center for Strategic and International Studies. Simply put, the Sarmat is a doomsday weapon designed for use in an all-out nuclear war between Russia and the United States. The missile’s first full-scale test flight in 2022 apparently went well, but the program has suffered a string of consecutive failures since then, most notably a catastrophic explosion last year that destroyed the Sarmat missile’s underground silo in northern Russia.

ESA fills its coffers for launcher challenge. The European Space Agency’s (ESA) European Launcher Challenge received a significant financial commitment from its member states during the agency’s Ministerial Council meeting last week, European Spaceflight reports. The challenge is designed to support emerging European rocket companies while giving ESA and other European satellite operators more options to compete with the continent’s sole operational launch provider, Arianespace. Through the program, ESA will purchase launch services and co-fund capacity upgrades with the winners. ESA member states committed 902 million euros, or $1.05 billion, to the program at the recent Ministerial Council meeting.

Preselecting the competitors … In July, ESA selected two German companies—Isar Aerospace and Rocket Factory Augsburg—along with Spain’s PLD Space, France’s MaiaSpace, and the UK’s Orbex to proceed with the initiative’s next phase. ESA then negotiated with the governments of each company’s home country to raise money to support the effort. Germany, with two companies on the shortlist, is unsurprisingly a large contributor to the program, committing more than 40 percent of the total budget. France contributed nearly 20 percent, Spain funded nearly 19 percent, and the UK committed nearly 16 percent. Norway paid for 3 percent of the launcher challenge’s budget. Denmark, Portugal, Switzerland, and the Czech Republic contributed smaller amounts.

Europe at the service of South Korea. South Korea’s latest Earth observation satellite was delivered into a Sun-synchronous orbit Monday afternoon following a launch onboard a Vega C rocket by Arianespace, Spaceflight Now reports. The Korea Multi-Purpose Satellite-7 (Kompsat-7) mission launched from Europe’s spaceport in French Guiana. About 44 minutes after liftoff, the Kompsat-7 satellite was deployed into SSO at an altitude of 358 miles (576 kilometers). “By launching the Kompsat-7 satellite, set to significantly enhance South Korea’s Earth observation capabilities, Arianespace is proud to support an ambitious national space program,” said David Cavaillolès, CEO of Arianespace, in a statement.

Something of a rarity … The launch of Kompsat-7 is something of a rarity for Arianespace, which has dominated the international commercial launch market. It’s the first time in more than two years that a satellite for a customer outside Europe has been launched by Arianespace. The backlog for the light-class Vega C rocket is almost exclusively filled with payloads for the European Space Agency, the European Commission, or national governments in Europe. Arianespace’s larger Ariane 6 rocket has 18 launches reserved for the US-based Amazon Leo broadband network. (submitted by EllPeaTea)

South Korea’s homemade rocket flies again. South Korea’s homegrown space rocket Nuri took off from Naro Space Center on November 27 with the CAS500-3 technology demonstration and Earth observation satellite, along with 12 smaller CubeSat rideshare payloads, Yonhap News Agency reports. The 200-ton Nuri rocket debuted in 2021, when it failed to reach orbit on a test flight. Since then, the rocket has successfully reached orbit three times. This mission marked the first time for Hanwha Aerospace to oversee the entire assembly process as part of the government’s long-term plan to hand over space technologies to the private sector. The fifth and sixth launches of the Nuri rocket are planned in 2026 and 2027.

Powered by jet fuel … The Nuri rocket has three stages, each with engines burning Jet A-1 fuel and liquid oxygen. The fuel choice is unusual for rockets, with highly refined RP-1 kerosene or methane being more popular among hydrocarbon fuels. The engines are manufactured by Hanwha Aerospace. The fully assembled rocket stands about 155 feet (47.2 meters) tall and can deliver up to 3,300 pounds (1.5 metric tons) of payload into a polar Sun-synchronous orbit.

Hyundai eyes rocket engine. Meanwhile, South Korea’s space sector is looking to the future. Another company best known for making cars has started a venture in the rocket business. Hyundai Rotem, a member of Hyundai Motor Group, announced a joint program with Korean Air’s Aerospace Division (KAL-ASD) to develop a 35-ton-class reusable methane rocket engine for future launch vehicles. The effort is funded with KRW49 billion ($33 million) from the Korea Research Institute for Defense Technology Planning and Advancement (KRIT).

By the end of the decade … The government-backed program aims to develop the engine by the end of 2030. Hyundai Rotem will lead the engine’s planning and design, while Korean Air, the nation’s largest air carrier, will lead development of the engine’s turbopump. “Hyundai Rotem began developing methane engines in 1994 and has steadily advanced its methane engine technology, achieving Korea’s first successful combustion test in 2006,” Hyundai Rotem said in a statement. “Furthermore, this project is expected to secure the technological foundation for the commercialization of methane engines for reusable space launch vehicles and lay the groundwork for targeting the global space launch vehicle market.”

But who needs rocket engines? Moonshot Space, based in Israel, announced Monday that it has secured $12 million in funding to continue the development of a launch system—powered not by chemical propulsion, but electromagnetism, Payload reports. Moonshot plans to sell other aerospace and defense companies the tech as a hypersonic test platform, while at the same time building to eventually offer orbital launch services. Instead of conventional rocket engines, the system would use a series of electromagnetic coils to power a hardened capsule to hypersonic velocities. The architecture has a downside: extremely high accelerations that could damage or destroy normal satellites. Instead, Moonshot wants to use the technology to send raw materials to orbit, lowering the input costs of the budding in-space servicing, refueling, and manufacturing industries, according to Payload.

Out of the shadows … Moonshot Space emerged from stealth mode with this week’s fundraising announcement. The company’s near-term focus is on building a scaled-down electromagnetic accelerator capable of reaching Mach 6. A larger system would be required to reach orbital velocity. The company’s CEO is the former director-general of Israel’s Ministry of Science, while its chief engineer was the former chief systems engineer for David’s Sling, a critical part of Israel’s missile defense system.

A blunder at Baikonur. A Soyuz rocket launched on November 27 carrying Roscosmos cosmonauts Sergei Kud-Sverchkov and Sergei Mikayev, as well as NASA astronaut Christopher Williams, for an eight-month mission to the International Space Station. The trio of astronauts arrived at the orbiting laboratory without incident. However, on the ground, there was a serious problem during the launch with the ground systems that support processing of the vehicle before liftoff at Site 31, located at the Baikonur Cosmodrome in Kazakhstan, Ars reports. Roscosmos downplayed the incident, saying only, in passive voice, that “damage to several launch pad components was identified” following the launch.

Repairs needed … However, video imagery of the launch site after liftoff showed substantial damage, with a large service platform appearing to have fallen into the flame trench below the launch table. According to one source, this is a platform located beneath the rocket, where workers can access the vehicle before liftoff. It has a mass of about 20 metric tons and was apparently not secured prior to launch, and the thrust of the vehicle ejected it into the flame trench. “There is significant damage to the pad,” said this source. The damage could throw a wrench into Russia’s ability to launch crews and cargo to the International Space Station. This Soyuz launch pad at Baikonur is the only one outfitted to support such missions.

China’s LandSpace almost landed a rocket. China’s first attempt to land an orbital-class rocket may have ended in a fiery crash, but the company responsible for the mission had a lot to celebrate with the first flight of its new methane-fueled launcher, Ars reports. LandSpace, a decade-old company based in Beijing, launched its new Zhuque-3 rocket for the first time Tuesday (US time) at the Jiuquan launch site in northwestern China. The upper stage of the medium-lift rocket successfully reached orbit. This alone is a remarkable achievement for a new rocket. But LandSpace had other goals for this launch. The Zhuque-3, or ZQ-3, booster stage is architected for recovery and reuse, the first rocket in China with such a design. The booster survived reentry and was seconds away from a pinpoint landing when something went wrong during its landing burn, resulting in a high-speed crash at the landing zone in the Gobi Desert.

Let the games begin … LandSpace got closer to landing an orbital-class booster than any other company on their first try. While LandSpace prepares for a second launch, several more Chinese companies are close to debuting their own reusable rockets. The next of these new rockets, the Long March 12A, is awaiting its first liftoff later this month from another launch pad at the Jiuquan spaceport. The Long March 12A comes from one of China’s established rocket developers, the Shanghai Academy of Spaceflight Technology (SAST), part of the country’s state-owned aerospace enterprise.

China launches a lifeboat. An unpiloted Chinese spacecraft launched on November 24 (US time) and linked with the country’s Tiangong space station a few hours later, providing a lifeboat for three astronauts stuck in orbit without a safe ride home, Ars reports. A Long March 2F rocket lifted off with the Shenzhou 22 spacecraft, carrying cargo instead of a crew. The spacecraft docked with the Tiangong station nearly 250 miles (400 kilometers) above the Earth about three-and-a-half hours later. Shenzhou 22 will provide a ride home next year for three Chinese astronauts. Engineers deemed their primary lifeboat unsafe after finding a cracked window, likely from an impact with a tiny piece of space junk.

In record time … Chinese engineers worked fast to move up the launch of the Shenzhou 22, originally set to fly next year. The launch occurred just 16 days after officials decided they needed to send another spacecraft to the Tiangong station. Shenzhou 22 and its rocket were already in standby at the launch site, but teams had to fuel the spacecraft and complete assembly of the rocket, then roll the vehicle to the launch pad for final countdown preps. The rapid turnaround offers a “successful example for efficient emergency response in the international space industry,” the China Manned Space Agency said. “It vividly embodies the spirit of manned spaceflight: exceptionally hardworking, exceptionally capable, exceptionally resilient, and exceptionally dedicated.”

Another big name flirts with the launch industry. OpenAI chief executive Sam Altman has explored putting together funds to either acquire or partner with a rocket company, a move that would position him to compete with Elon Musk’s SpaceX, the Wall Street Journal reports. Altman reached out to at least one rocket maker, Stoke Space, in the summer, and the discussions picked up in the fall, according to people familiar with the talks. Among the proposals was for OpenAI to make a multibillion-dollar series of equity investments in the company and end up with a controlling stake. The talks are no longer active, people close to OpenAI told the Journal.

Here’s the reason … Altman has been interested in building data centers in space for some time, the Journal reports, suggesting that the insatiable demand for computing resources to power artificial-intelligence systems eventually could require so much power that the environmental consequences would make space a better option. Orbital data centers would allow companies to harness the power of the Sun to operate them. Alphabet’s Google is pursuing a similar concept in partnership with satellite operator Planet Labs. Jeff Bezos and Musk himself have also expressed interest in the idea. Outside of SpaceX and Blue Origin, Stoke Space seems to be a natural partner for such a project because it is one of the few companies developing a fully reusable rocket.

SpaceX gets green light for new Florida launch pad. SpaceX has the OK to build out what will be the primary launch hub on the Space Coast for its Starship and Super Heavy rocket, the most powerful launch vehicle in history, the Orlando Sentinel reports. The Department of the Air Force announced Monday it had approved SpaceX to move forward with the construction of a pair of launch pads at Cape Canaveral Space Force Station’s Space Launch Complex 37 (SLC-37). A “record of decision” on the Environmental Impact Statement required under the National Environmental Policy Act for the proposed Canaveral site was posted to the Air Force’s website, marking the conclusion of what has been a nearly two-year approval process.

Get those Starships ready … SpaceX plans to build two launch towers at SLC-37 to augment the single tower under construction at NASA’s Kennedy Space Center, just a few miles to the north. The three pads combined could support up to 120 launches per year. The Air Force’s final approval was expected after it released a draft Environmental Impact Statement earlier this year, suggesting the Starship pads at SLC-37 would have no significant negative impacts on local environmental, historical, social, and cultural interests. The Air Force also found SpaceX’s plans at SLC-37, formerly leased by United Launch Alliance, will have no significant impact on the company’s competitors in the launch industry. SpaceX also has two launch towers at its Starbase facility in South Texas.

Sizing up the 5 companies selected for Europe’s launcher challenge

Europe, european space agency, isar aerospace, launch, MaiaSpace, orbex, pld space, rocket factory Augsburg, Science, Space / /

The European Space Agency has selected five launch startups to become eligible for up to 169 million euros ($198 million) in funding to develop alternatives to Arianespace, the continent’s incumbent launch service provider.

The five companies ESA selected are Isar Aerospace, MaiaSpace, Rocket Factory Augsburg, PLD Space, and Orbex. Only one of these companies, Isar Aerospace, has attempted to launch a rocket into orbit. Isar’s Spectrum rocket failed moments after liftoff from Norway on a test flight in March.

None of these companies are guaranteed ESA contracts or funding. Over the next several months, the European Space Agency and the five launch companies will negotiate with European governments for funding leading up to ESA’s ministerial council meeting in November, when ESA member states will set the agency’s budget for at least the next two years. Only then will ESA be ready to sign binding agreements.

In a press release, ESA referred to the five companies as “preselected challengers” in a competition for ESA support in the form of launch contracts and an ESA-sponsored demonstration to showcase upgraded launch vehicles to heave heavier payloads into orbit. So far, all five of the challengers are focusing on small rockets.

Earlier this year, ESA released a request for proposals to European industry for bids to compete in the European Launch Challenge. ESA received 12 proposals from European companies and selected five to move on to the next phase of the challenge.

A new way of doing business

In this competition, ESA is eschewing a rule that governs nearly all of the space agency’s other programs. This policy, known as geographic return, guarantees industrial contracts to ESA member states commensurate with the level of money they put into each project. The most obvious example of this is Europe’s Ariane rocket family, whose development was primarily funded by France, followed by Germany in second position. Therefore, the Ariane 6 rocket’s core stage and engines are built in France, and its upper stage is manufactured in Germany.

Welcome to Edition 7.37 of the Rocket Report! It’s been interesting to watch how quickly European officials have embraced ensuring they have a space launch capability independent of other countries. A few years ago, European government satellites regularly launched on Russian Soyuz rockets, and more recently on SpaceX Falcon 9 rockets from the United States. Russia is now non grata in European government circles, and the Trump administration is widening the trans-Atlantic rift. European leaders have cited the Trump administration and its close association with Elon Musk, CEO of SpaceX, as prime reasons to support sovereign access to space, a capability currently offered only by Arianespace. If European nations can reform how they treat their commercial space companies, there’s enough ambition, know-how, and money in Europe to foster a competitive launch industry.

As always, we welcome reader submissions. If you don’t want to miss an issue, please subscribe using the box below (the form will not appear on AMP-enabled versions of the site). Each report will include information on small-, medium-, and heavy-lift rockets as well as a quick look ahead at the next three launches on the calendar.

Isar Aerospace aims for weekend launch. A German startup named Isar Aerospace will try to launch its first rocket Saturday, aiming to become the first in a wave of new European launch companies to reach orbit, Ars reports. The Spectrum rocket consists of two stages, stands about 92 feet (28 meters) tall, and can haul payloads up to 1 metric ton (2,200 pounds) into low-Earth orbit. Based in Munich, Isar was founded by three university graduate students in 2018. Isar scrubbed a launch attempt Monday due to unfavorable winds at the launch site in Norway.

From the Arctic … Notably, this will be the first orbital launch attempt from a launch pad in Western Europe. The French-run Guiana Space Center in South America is the primary spaceport for European rockets. Virgin Orbit staged an airborne launch attempt from an airport in the United Kingdom in 2023, and the Plesetsk Cosmodrome is located in European Russia. The launch site for Isar is named Andøya Spaceport, located about 650 miles (1,050 kilometers) north of Oslo, inside the Arctic Circle. (submitted by EllPeaTea)

A chance for competition in Europe. The European Space Agency is inviting proposals to inject competition into the European launch market, an important step toward fostering a dynamic multiplayer industry officials hope one day will mimic that of the United States, Ars reports. The near-term plan for the European Launcher Challenge is for ESA to select companies for service contracts to transport ESA and other European government payloads to orbit from 2026 through 2030. A second component of the challenge is for companies to perform at least one demonstration of an upgraded launch vehicle by 2028. The competition is open to any European company working in the launch business.

Challenging the status quo … This is a major change from how ESA has historically procured launch services. Arianespace has been the only European launch provider available to ESA and other European institutions for more than 40 years. But there are private companies across Europe at various stages of developing their own small launchers, and potentially larger rockets, in the years ahead. With the European Launcher Challenge, ESA will provide each of the winners up to 169 million euros ($182 million), a significant cash infusion that officials hope will shepherd Europe’s nascent private launch industry toward liftoff. Companies like Isar Aerospace, Rocket Factory Augsburg, MaiaSpace, and PLD Space are among the contenders for ESA contracts.

Rocket Lab launches eight satellites. Rocket Lab launched eight satellites Wednesday for a German company that is expanding its constellation to detect and track wildfires, Space News reports. An Electron rocket lifted off from New Zealand and completed deploying its payload of eight CubeSats for OroraTech about 55 minutes later, placing them into Sun-synchronous orbits at an altitude of about 341 miles (550 kilometers). This was Rocket Lab’s fifth launch of the year, and the third in less than two weeks.

Fire goggles … OroraTech launched three satellites before this mission, fusing data from those satellites and government missions to detect and track wildfires. The new satellites are designed to fill a gap in coverage in the afternoon, a peak time for wildfire formation and spread. OroraTech plans to launch eight more satellites later this year. Wildfire monitoring from space is becoming a new application for satellite technology. Last month, OroraTech partnered with Spire for a contract to build a CubeSat constellation called WildFireSat for the Canadian Space Agency. Google is backing FireSat, another constellation of more than 50 satellites to be deployed in the coming years to detect and track wildfires. (submitted by EllPeaTea)

Should Britain have a sovereign launch capability? A UK House of Lords special inquiry committee has heard from industry experts on the importance of fostering a sovereign launch capability, European Spaceflight reports. On Monday, witnesses from the UK space industry testified that the nation shouldn’t rely on others, particularly the United States, to put satellites into orbit. “The idea that we will be able to do it through America… certainly in today’s, you know, the last 50 days, I think is very, very doubtful. The UK needs access to space,” said Scott Hammond, deputy CEO of SaxaVord Spaceport in Scotland.

Looking inward … A representative from one of the most promising UK launch startups agreed. “Most people who are looking to launch are beholden to the United States solutions or services that are there,” said Alan Thompson, head of government affairs at Skyrora. “Without having our own home-based or UK-based service provider, we risk not having that voice and not being able to undertake all these experiments or be able to manifest ourselves better in space.” The UK is the only nation to abandon an independent launch capability after putting a satellite into orbit. The British government canceled the Black Arrow rocket in the early 1970s, citing financial reasons. A handful of companies, including Skyrora, is working to restore the orbital launch business to the UK.

This rocket engine CEO faces some salacious allegations. The Independent published what it described as an exclusive report Monday describing a lawsuit filed against the CEO of RocketStar, a New York-based company that says its mission is “improving upon the engines that power us to the stars.” Christopher Craddock is accused of plundering investor funds to underwrite pricey jaunts to Europe, jewelry for his wife, child support payments, and, according to the company’s largest investor, “airline tickets for international call girls to join him for clandestine weekends in Miami,” The Independent reports. Craddock established RocketStar in 2014 after financial regulators barred him from working on Wall Street over a raft of alleged violations.

Go big or go home … The $6 million lawsuit filed by former CEO Michael Mojtahedi alleges RocketStar “is nothing more than a Ponzi scheme… [that] has been predicated on Craddock’s ability to con new people each time the company has run out of money.” On its website, RocketStar says its work focuses on aerospike rocket engines and a “FireStar Fusion Drive, the world’s first electric propulsion device enhanced with nuclear fusion.” These are tantalizing technologies that have proven elusive for other rocket companies. RocketStar’s attorney told The Independent: “The company denies the allegations and looks forward to vindicating itself in court.”

Another record for SpaceX. Last Thursday, SpaceX launched a batch of clandestine SpaceX-built surveillance satellites for the National Reconnaissance Office from Vandenberg Space Force Base in California, Spaceflight Now reports. This was the latest in a series of flights populating the NRO’s constellation of low-Earth orbit reconnaissance satellites. What was unique about this mission was its use of a Falcon 9 first stage booster that flew to space just nine days prior with a NASA astronomy satellite. The successful launch broke the record for the shortest span between flights of the same Falcon 9 booster, besting a 13.5-day turnaround in November 2024.

A mind-boggling number of launches … This flight also marked the 450th launch of a Falcon 9 rocket since its debut in 2010, and the 139th within a 365-day period, despite suffering its first mission failure in nearly 10 years and a handful of other glitches. SpaceX’s launch pace is unprecedented in the history of the space industry. No one else is even close. In the last Rocket Report I authored, I wrote that SpaceX’s steamroller no longer seems to be rolling downhill. That may be the case as the growth in the Falcon 9 launch cadence has slowed, but it’s hard for me to see anyone else matching SpaceX’s launch rate until at least the 2030s.

Rocket Lab and Stoke Space find an on-ramp. Space Systems Command announced Thursday that it selected Rocket Lab and Stoke Space to join the Space Force’s National Security Space Launch (NSSL) program. The contracts have a maximum value of $5.6 billion, and the Space Force will dole out “task orders” for individual missions as they near launch. Rocket Lab and Stoke Space join SpaceX, ULA, and Blue Origin as eligible launch providers for lower-priority national security satellites, a segment of missions known as Phase 3 Lane 1 in the parlance of the Space Force. For these missions, the Space Force won’t require certification of the rockets, as the military does for higher-value missions in the so-called “Lane 2” segment. However, Rocket Lab and Stoke Space must complete at least one successful flight of their new Neutron and Nova rockets before they are cleared to launch national security payloads.

Stoked at Stoke … This is a big win for Rocket Lab and Stoke. For Rocket Lab, it bolsters the business case for the medium-class Neutron rocket it is developing for flights from Wallops Island, Virginia. Neutron will be partially reusable with a recoverable first stage. But Rocket Lab already has a proven track record with its smaller Electron launch vehicle. Stoke hasn’t launched anything, and it has lofty ambitions for a fully reusable two-stage rocket called Nova. This is a huge vote of confidence in Stoke. When the Space Force released its invitation for an on-ramp to the NSSL program last year, it said bidders must show a “credible plan for a first launch by December 2025.” Smart money is that neither company will launch its rockets by the end of this year, but I’d love to be proven wrong.

Falcon 9 deploys spy satellite. Monday afternoon, a SpaceX Falcon 9 took flight from Florida’s Space Coast and delivered a national security payload designed, built, and operated by the National Reconnaissance Office into orbit, Florida Today reports. Like almost all NRO missions, details about the payload are classified. The mission codename was NROL-69, and the launch came three-and-a-half days after SpaceX launched another NRO mission from California. While we have some idea of what SpaceX launched from California last week, the payload for the NROL-69 mission is a mystery.

Space sleuthing … There’s an online community of dedicated skywatchers who regularly track satellites as they sail overhead around dawn and dusk. The US government doesn’t publish the exact orbital parameters for its classified spy satellites (they used to), but civilian trackers coordinate with one another, and through a series of observations, they can produce a pretty good estimate of a spacecraft’s orbit. Marco Langbroek, a Dutch archeologist and university lecturer on space situational awareness, is one of the best at this, using publicly available information about the flight path of a launch to estimate when the satellite will fly overhead. He and three other observers in Europe managed to locate the NROL-69 payload just two days after the launch, plotting the object in an orbit between 700 and 1,500 kilometers at an inclination of 64.1 degrees to the equator. Analysts speculated this mission might carry a pair of naval surveillance spacecraft, but this orbit doesn’t match up well with any known constellations of NRO satellites.

NASA continues with Artemis II preps. Late Saturday night, technicians at Kennedy Space Center in Florida moved the core stage for NASA’s second Space Launch System rocket into position between the vehicle’s two solid-fueled boosters, Ars reports. Working inside the iconic 52-story-tall Vehicle Assembly Building, ground teams used heavy-duty cranes to first lift the butterscotch orange core stage from its cradle, then rotate it to a vertical orientation and lift it into a high bay, where it was lowered into position on a mobile launch platform. The 212-foot-tall (65-meter) core stage is the largest single hardware element for the Artemis II mission, which will send a team of four astronauts around the far side of the Moon and back to Earth as soon as next year.

Looking like a go … With this milestone, the slow march toward launch continues. A few months ago, some well-informed people in the space community thought there was a real possibility the Trump administration could quickly cancel NASA’s Space Launch System, the high-priced heavy-lifter designed to send astronauts from the Earth to the Moon. The most immediate possibility involved terminating the SLS program before it flies with Artemis II. This possibility appears to have been overcome by circumstances. The rockets most often mentioned as stand-ins for the Space Launch System—SpaceX’s Starship and Blue Origin’s New Glenn—aren’t likely to be cleared for crew missions for at least several years. The long-term future of the Space Launch System remains in doubt.

Space Force says Vulcan is good to go. The US Space Force on Wednesday announced that it has certified United Launch Alliance’s Vulcan rocket to conduct national security missions, Ars reports. “Assured access to space is a core function of the Space Force and a critical element of national security,” said Brig. Gen. Kristin Panzenhagen, program executive officer for Assured Access to Space, in a news release. “Vulcan certification adds launch capacity, resiliency, and flexibility needed by our nation’s most critical space-based systems.” The formal announcement closes a yearslong process that has seen multiple delays in the development of the Vulcan rocket, as well as two anomalies in recent years that were a further setback to certification.

Multiple options … This certification allows ULA’s Vulcan to launch the military’s most sensitive national security missions, a separate lot from those Rocket Lab and Stoke Space are now eligible for (as we report in a separate Rocket Report entry). It elevates Vulcan to launch these missions alongside SpaceX’s Falcon 9 and Falcon Heavy rockets. Vulcan will not be the next rocket that the company launches, however. First up is one of the company’s remaining Atlas V boosters, carrying Project Kuiper broadband satellites for Amazon. This launch could occur in April, although ULA has not set a date. This will be followed by the first Vulcan national security launch, which the Space Force says could occur during the coming “summer.”

this-launcher-is-about-to-displace-the-v-2-as-germany’s-largest-rocket

This launcher is about to displace the V-2 as Germany’s largest rocket

Commercial space, Europe, european space agency, germany, isar aerospace, launch, Norway, Science, Space / /

Isar Aerospace’s first Spectrum rocket will launch from Andøya Spaceport in Norway.

Seven years ago, three classmates at the Technical University of Munich believed their student engineering project might hold some promise in the private sector.

At the time, one of the co-founders, Daniel Metzler, led a team of 40 students working on rocket engines and launching sounding rockets. Josef Fleischmann was on the team that won the first SpaceX Hyperloop competition. Together with another classmate, Markus Brandl, they crafted rocket parts in a campus workshop before taking the leap and establishing Isar Aerospace, named for the river running through the Bavarian capital.

Now, Isar’s big moment has arrived. The company’s orbital-class first rocket, named Spectrum, is set to lift off from a shoreline launch pad in Norway as soon as Monday.

The three-hour launch window opens at 12: 30 pm local time in Norway, or 7: 30 am EDT in the United States. “The launch date remains subject to weather, safety and range infrastructure,” Isar said in a statement.

Isar said it received a launch license from the Norwegian Civil Aviation Authority on March 14, following the final qualification test on the Spectrum rocket in February to validate its readiness for flight.

Notably, this will be the first orbital launch attempt from a launch pad in Western Europe. The French-run Guiana Space Center in South America is the primary spaceport for European rockets. Virgin Orbit staged an airborne launch attempt from an airport in the United Kingdom in 2023, and the Plesetsk Cosmodrome is located in European Russia.

No guarantees

Success is never assured on the inaugural launch of a new rocket. Isar is the first in a wave of European launch startups to arrive at this point. The company developed the Spectrum rocket with mostly private funding, although Isar received multimillion-euro investments from the European Space Agency, the German government, and the NATO Innovation Fund.

All told, Isar says it has raised more than 400 million euros, or $435 million at today’s currency exchange rate, more than any other European launch startup.

“We are approaching the most important moment of our journey so far, and I would like to thank all our team, partners, customers and investors who have been accompanying and trusting us,” said Daniel Metzler, Isar’s co-founder and CEO, in a statement.

Most privately-developed rockets have failed to reach orbit on the first try. Several US launch companies that evolved in a similar mold as Isar—such as Rocket Lab, Firefly Aerospace, and Astra—faltered on the way to orbit on their rockets’ first flights.

“With this mission, Isar Aerospace aims to collect as much data and experience as possible on its in-house developed launch vehicle. It is the first integrated test of all systems,” said Alexandre Dalloneau, Isar’s vice president of mission and launch operations.

“The test results will feed into the iterations and development of future Spectrum vehicles, which are being built and tested in parallel,” Isar said in a statement.

Europe has struggled to regain its footing after SpaceX took over the dominant position in the global commercial launch market, a segment led for three decades by Europe’s Ariane rocket family before SpaceX proved the reliability of the lower-cost, partially reusable Falcon 9 launcher. The continent’s new Ariane 6 rocket, funded by ESA and built by a consortium owned by multinational firms Airbus and Safran, is more expensive than the Falcon 9 and years behind schedule. It finally debuted last year.

One ton to LEO

Isar’s Spectrum rocket is not as powerful as the SpaceX’s Falcon 9 or Arianespace’s Ariane 6. But even SpaceX had to start somewhere. Its small Falcon 1 rocket failed three times before tasting success. Spectrum is somewhat larger and more capable than Falcon 1, with performance in line with Firefly’s Alpha rocket.

The fully assembled Spectrum rocket stands about 92 feet (28 meters) tall and measures more than 6 feet (2 meters) in diameter. The expendable launcher is designed to haul payloads up to 1 metric ton (2,200 pounds) into low-Earth orbit. Spectrum is powered by nine Aquila engines on its first stage, and one engine on the second stage, burning a mixture of propane and liquid oxygen propellants.

There are no customer satellites aboard the first Spectrum test flight. The rocket will climb into a polar orbit from Andøya Spaceport in northern Norway, but Isar hasn’t published a launch timeline or the exact parameters of the target orbit.

While modest in size next to Europe’s Ariane launcher family, Isar’s Spectrum is the largest German rocket since the V-2, the World War II weapon of terror launched by Nazi Germany against targets in Great Britain, Belgium, and other places. In the 80 years since the war, German industry developed a handful of small sounding rockets, and manufactured upper stages for Ariane rockets.

But German governments have long shunned spending on launchers at levels commensurate with the nation’s place as a top contributor to ESA. France took the lead in the continent’s postwar rocket industry, providing the lion’s share of funding for Ariane, and taking responsibility for building engines and booster stages.

Now, 80 years to the week since the last V-2 launch of World War II, Germany again has a homegrown liquid-fueled rocket on the launch pad. This time, it’s for a much different purpose.

As a first step, Isar and other companies in Europe are vying to inject competition with Arianespace into the European launch market. This will begin with small government-funded satellites that otherwise would have likely launched on rideshare flights by SpaceX or Arianespace.

In 2022, the German space agency (known as DLR) announced the selection of research and demo payloads slated to fly on Spectrum’s second launch. The Norwegian Space Agency revealed a contract earlier this month for Isar to launch a pair of satellites for the country’s Arctic Ocean Surveillance program.

Within the next few days, ESA is expected to release an “invitation to tender” for European industry to submit proposals for the European Launcher Challenge. This summer, ESA will select winners from Europe’s crop of launch startups to demonstrate their rockets can deliver the agency’s scientific satellites to orbit. This is the first time ESA has experimented with a fully commercial business model, with launch service contracts to private companies. Isar is a leading contender to win the launcher challenge, alongside other European companies like Rocket Factory Augsburg, HyImpulse, MaiaSpace, and others.

Previously, ESA has provided billions of euros to Europe’s big incumbent rocket companies for development of new generations of Ariane rockets. Now, ESA wants follow the path of NASA, which has used fixed-price service contracts to foster commercial cargo and crew transportation to the International Space Station, and most recently, privately-owned landers on the Moon.

“Whatever the outcome, Isar Aerospace’s upcoming Spectrum launch will be historic: the first commercial orbital launch from mainland Europe,” Josef Aschbacher, ESA’s director general, posted on X. “The support and co-funding the European Space Agency has given Isar Aerospace and other launch service provider startups is paying off for increased autonomy in Europe. Wishing Isar Aerospace a great launch day with fair weather and most importantly, that the data they receive from the liftoff will speed next iterations of their rockets.”

Toni Tolker-Nielsen, ESA’s acting director of space transportation, called this moment a “paradigm shift” for Europe’s launcher strategy.

“In the last 40 years, we have had these ESA-developed launchers that we have been relying on,” Tolker-Nielsen told Ars in an interview. “So we started with Ariane 1 up to Ariane 6. Vega C came onboard. And it’s been working like that for the last 40 years. Now, we are moving into in the ’30s, and the next decades, to have privately-developed launchers.”

Isar Aerospace’s first Spectrum rocket will lift off from the remote Andøya Spaceport in Norway, a gorgeous location that might be the world’s most picturesque launch site. Nestled on the western coast of an island inside the Arctic Circle, Andøya offers an open path over the Norwegian Sea for rockets to fly north, where they can place satellites into polar orbit.

The spaceport is operated by Andøya Space, a company 90 percent owned by the Norwegian government through the Ministry for Trade, Industry, and Fisheries. Until now, Andøya Spaceport has been used for launches of suborbital sounding rockets.

No better time than now

Isar’s first launch comes amid an abrupt turn in European strategic policy as the continent’s leaders struggle with how to respond to moves by President Donald Trump in his first two months in office. In recent weeks, the Trump administration put European leaders on their heels with sudden policy reversals and unpredictable statements on Ukraine, NATO, and the US government’s long-term backstopping of European security.

Friedrich Merz, set to become Germany’s next chancellor, said last month that Europe should strive to “achieve independence” from the United States. “It is clear that the Americans, at least this part of the Americans, this administration, are largely indifferent to the fate of Europe.”

Last week, Merz shepherded a bill through German parliament to amend the country’s constitution, allowing for a significant increase in German defense spending. The incoming chancellor said the change is “nothing less than the first major step towards a new European defense community.”

The erosion of Europe’s trust in the Trump administration prompted rumors that the US government could trigger a “kill switch” to turn off combat capabilities of F-35 fighter jets sold to US allies. This would have previously seemed like a far-fetched conspiracy theory, but some European officials felt compelled to make statements denying the kill switch reports. Still, the recent turbulence in trans-Atlantic relations has some US allies rethinking their plans to buy more US-made fighter jets and weapons systems.

“Reliable and predictable orders should go to European manufacturers whenever possible,” Merz said.

This uncertainty extends to space, where it is most apparent in the launch industry. SpaceX, founded and led by Trump ally Elon Musk, dominates the global commercial launch business. European governments have repeatedly turned to SpaceX to launch multiple defense and scientific satellites over the last several years, while Europe encountered delays with its homegrown Ariane 6 and Vega rockets.

Until 2022, Europe and Russia jointly operated Soyuz rockets from the Guiana Space Center in South America to deploy government and commercial payloads to orbit. The partnership ended with Russia’s invasion of Ukraine.

Europe’s flagship Ariane 5 rocket retired in 2023, a year before its replacement—the Ariane 6—debuted on its first test flight from the Guiana Space Center. The first operational flight of the Ariane 6 delivered a French military spy satellite to orbit March 6. The smaller Vega C rocket successfully launched in December, two years after officials grounded the vehicle due to an in-flight failure.

ESA funded development of the Ariane 6 and Vega C in partnership with ArianeGroup, a joint venture between Airbus and Safran, and the Italian defense contractor Avio.

For the moment, Europe’s launcher program is back on track to provide autonomous access to space, a capability European officials consider a strategic imperative. Philippe Baptiste, France’s minister for research and higher education, said after the Ariane 6 flight earlier this month that the launch was “proof” of European space sovereignty.

“The return of Donald Trump to the White House, with Elon Musk at his side, already has significant consequences on our research partnerships, on our commercial partnerships,” Baptiste said in his remarkably pointed prepared remarks. “If we want to maintain our independence, ensure our security, and preserve our sovereignty, we must equip ourselves with the means for strategic autonomy, and space is an essential part of this.”

The problem? Ariane 6 and Vega C are costly, lack a path to reusability, and aren’t geared to match SpaceX’s blistering launch cadence. If Europe wants autonomous access to space, European taxpayers will have to pay a premium. Isar’s Spectrum also isn’t reusable, but European officials hope competition from new startups will produce fresh launch options, and perhaps stimulate an inspired response from Europe’s entrenched launch companies.

“In today’s geopolitical climate, our first test flight is about much more than a rocket launch: Space is one of the most critical platforms for our security, resilience and technological advancement,” Metzler said. “In the next days, Isar Aerospace will lay the foundations to regain much needed independent and competitive access to space from Europe.”

Tolker-Nielsen, in charge of ESA’s space transportation division, said this is the first of many steps for Europe to develop a thriving commercial launch sector.

“This launch is a milestone, which is very important,” he said. “It’s the first conclusion of all this work, so I will be looking carefully on that. I cross my fingers that it goes well.”

Isar builds almost all of its rockets in-house, including Spectrum’s Aquila engines.

“The flight will be the first integrated test of tens of thousands of components,” said Josef Fleischmann, Isar’s co-founder and chief technical officer. “Regardless of how far we get, this first test flight will hopefully generate an enormous amount of data and experience which we can apply to future missions.”

Isar is the first European startup to reach this point in development. “Reaching this milestone is a huge success in itself,” Meltzer said in a statement. “And while Spectrum is ready for its first test flight, launch vehicles for flights two and three are already in production.”

Another Bavarian company, Rocket Factory Augsburg, destroyed its first booster during a test-firing on its launch pad in Scotland last year, ceding the frontrunner mantle to Isar. RFA received its launch license from the UK government last month and aims to deliver its second booster to the launch site for hot-fire testing and a launch attempt later this year.

There’s an appetite within the European launch industry for new companies to compete with Arianespace, the continent’s sole operational launch services provider backed by substantial government support. Delays in developing the Ariane 6 rocket and several failures of Europe’s smaller Vega launcher forced European satellite operators to look abroad, primarily to SpaceX, to launch their payloads.

The European Space Agency is organizing the European Launcher Challenge, a competition that will set aside some of the agency’s satellites for launch opportunities with a new crop of startups. Isar is one of the top contenders in the competition to win money from ESA. The agency expects to award funding to multiple European launch providers after releasing a final solicitation later this year.

The first flight of the Spectrum rocket will attempt to reach a polar orbit, flying north from Andøya Spaceport. Located at approximately 69 degrees north latitude, the spaceport is poised to become the world’s northernmost orbital launch site.

Because the inaugural launch of the Spectrum rocket is a test flight, it won’t carry any customer payloads, an Isar spokesperson told Ars.

Welcome to Edition 7.11 of the Rocket Report! Outside of companies owned by American billionaires, the most imminent advancements in reusable rockets are coming from China’s quasi-commercial launch industry. This industry is no longer nascent. After initially relying on solid-fueled rocket motors apparently derived from Chinese military missiles, China’s privately funded launch firms are testing larger launchers, with varying degrees of success, and now performing hop tests reminiscent of SpaceX’s Grasshopper and F9R Dev1 programs more than a decade ago.

As always, we welcome reader submissions. If you don’t want to miss an issue, please subscribe using the box below (the form will not appear on AMP-enabled versions of the site). Each report will include information on small-, medium-, and heavy-lift rockets as well as a quick look ahead at the next three launches on the calendar.

Landspace hops closer to a reusable rocket. Chinese private space startup Landspace has completed a 10-kilometer (33,000-foot) vertical takeoff and vertical landing test on its Zhuque-3 (ZQ-3) reusable rocket testbed, including a mid-flight engine reignition at near supersonic conditions, Aviation Week & Space Technology reports. The 18.3-meter (60-foot) vehicle took off from the Jiuquan launch base in northwestern China, ascended to 10,002 meters, and then made a vertical descent and achieved an on-target propulsive landing 3.2 kilometers (2 miles) from the launch pad. Notably, the rocket’s methane-fueled variable-thrust engine intentionally shutdown in flight, then reignited for descent, as engines would operate on future full-scale booster flybacks. The test booster used grid fins and cold gas thrusters to control itself when its main engine was dormant, according to Landspace.

“All indicators met the expected design” … Landspace hailed the test as a major milestone in the company’s road to flying its next rocket, the Zhuque-3, as soon as next year. With nine methane-fueled main engines, the Zhuque-3 will initially be able to deliver 21 metric tons (46,300 pounds) of payload into low-Earth orbit with its booster flying in expendable mode. In 2026, Landspace aims to begin recovering Zhuque-3 first-stage boosters for reuse. Landspace is one of several Chinese companies working seriously on reusable rocket designs. Another Chinese firm, Deep Blue Aerospace, says it plans a 100-kilometer (62-mile) suborbital test of a reusable booster soon, ahead of the first flight of its medium-class Nebula-1 rocket next year.

Isar Aerospace sets low bar for success on first launch. Daniel Metzler, CEO of German launch startup Isar Aerospace, stated that the first flight of the Spectrum rocket would be a success if it didn’t destroy the launch site, European Spaceflight reports. During an interview at the Handelsblatt innovation conference, Metzler was asked what he would consider a successful inaugural flight of Spectrum. “For me, the first flight will be a success if we don’t blow up the launch site,” explained Metzler. “That would probably be the thing that would set us back the most in terms of technology and time.” This tempering of expectations sounds remarkably similar to statements made by Elon Musk about SpaceX’s first flight of the Starship rocket last year.

In the catbird seat? … Isar Aerospace could be in a position to become the first in a new crop of European commercial launch companies to attempt its first orbital flight. Another German company, Rocket Factory Augsburg, recently gave up on a possible launch this year after the booster for its first launch caught fire and collapsed during a test at a launch site in Scotland. Isar plans to launch its two-stage Spectrum rocket, designed to carry up to 1,000 kilograms (2,200 pounds) of payload into low-Earth orbit, from Andøya Spaceport in Norway. Isar hasn’t publicized any schedule for the first flight of Spectrum, but there are indications the publicity-shy company is testing hardware at the Norwegian spaceport. (submitted by Ken the Bin)

FAA to introduce new orbital debris rules. The Federal Aviation Administration is moving ahead with efforts to develop rules for the disposal of upper stages as another Centaur upper stage breaks apart in orbit, Space News reports. The FAA released draft regulations on the matter for public comment one year ago, and the head of the agency’s commercial spaceflight division recently said the rules are a “high priority for our organization.” The rules would direct launch operators to dispose of upper stages in one of five ways, from controlled reentries to placement in graveyard or “disposal” orbits not commonly used by operational satellites. One change the FAA might make to the draft rules is to reduce the required timeline for an uncontrolled reentry of a disposed upper stage from no more than 25 years to a shorter timeline. “We got a lot of comments that said it should be a lot less,” said Kelvin Coleman, head of the FAA’s commercial spaceflight office. “We’re taking that into consideration.”

Upper stages are a problem … Several recent breakups involving spent upper stages in orbit have highlighted the concern that dead rocket bodies could create unnecessary space junk. Last month, the upper stage from a Chinese Long March 6A disintegrated in low-Earth orbit, creating at least 300 pieces of space debris. More recently, a Centaur upper stage from a United Launch Alliance Atlas V rocket broke apart in a much higher orbit, resulting in more than 40 pieces of debris. This was the fourth time one of ULA’s Centaur upper stages has broken up since 2018. (submitted by Ken the Bin)
