CAPE CANAVERAL, FloridaThe field of astrodynamics isn’t a magical discipline, but sometimes it seems trajectory analysts can pull a solution out of a hat.

That’s what it took to save NASA’s ESCAPADE mission from a lengthy delay, and possible cancellation, after its rocket wasn’t ready to send it toward Mars during its appointed launch window last year. ESCAPADE, short for Escape and Plasma Acceleration and Dynamics Explorers, consists of two identical spacecraft setting off for the red planet as soon as Sunday with a launch aboard Blue Origin’s massive New Glenn rocket.

“ESCAPADE is pursuing a very unusual trajectory in getting to Mars,” said Rob Lillis, the mission’s principal investigator from the University of California, Berkeley. “We’re launching outside the typical Hohmann transfer windows, which occur every 25 or 26 months. We are using a very flexible mission design approach where we go into a loiter orbit around Earth in order to sort of wait until Earth and Mars are lined up correctly in November of next year to go to Mars.”

This wasn’t the original plan. When it was first designed, ESCAPADE was supposed to take a direct course from Earth to Mars, a transit that typically takes six to nine months. But ESCAPADE will now depart the Earth when Mars is more than 220 million miles away, on the opposite side of the Solar System.

The most recent Mars launch window was last year, and the next one doesn’t come until the end of 2026. The planets are not currently in alignment, and the proverbial stars didn’t align to get the ESCAPADE satellites and their New Glenn rocket to the launch pad until this weekend.

This is fine

But there are several reasons this is perfectly OK to NASA. The New Glenn rocket is overkill for this mission. The two-stage launcher could send many tons of cargo to Mars, but NASA is only asking it to dispatch about a ton of payload, comprising a pair of identical science probes designed to study how the planet’s upper atmosphere interacts with the solar wind.

But NASA got a good deal from Blue Origin. The space agency is paying Jeff Bezos’ space company about $20 million for the launch, less than it would for a dedicated launch on any other rocket capable of sending the ESCAPADE mission to Mars. In exchange, NASA is accepting a greater than usual chance of a launch failure. This is, after all, just the second flight of the 321-foot-tall (98-meter) New Glenn rocket, which hasn’t yet been certified by NASA or the US Space Force.

The ESCAPADE mission, itself, was developed with a modest budget, at least by the standards of interplanetary exploration. The mission’s total cost amounts to less than $80 million, an order of magnitude lower than all of NASA’s recent Mars missions. NASA officials would not entrust the second flight of the New Glenn rocket to launch a billion-dollar spacecraft, but the risk calculation changes as costs go down.

NASA knew all of this in 2023 when it signed a launch contract with Blue Origin for the ESCAPADE mission. What officials didn’t know was that the New Glenn rocket wouldn’t be ready to fly when ESCAPADE needed to launch in late 2024. It turned out Blue Origin didn’t launch the first New Glenn test flight until January of this year. It was a success. It took another 10 months for engineers to get the second New Glenn vehicle to the launch pad.

Aiming high

That’s where the rocket sits this weekend at Cape Canaveral Space Force Station, Florida. If all goes according to plan, New Glenn will take off Sunday afternoon during an 88-minute launch window opening at 2: 45 pm EST (19: 45 UTC). There is a 65 percent chance of favorable weather, according to Blue Origin.

Blue Origin’s launch team, led by launch director Megan Lewis, will oversee the countdown Sunday. The rocket will be filled with super-cold liquid methane and liquid oxygen propellants beginning about four-and-a-half hours prior to liftoff. After some final technical and weather checks, the terminal countdown sequence will commence at T-minus 4 minutes, culminating in ignition of the rocket’s seven BE-4 main engines at T-minus 5.6 seconds.

The rocket’s flight computer will assess the health of each of the powerful engines, combining to generate more than 3.8 million pounds of thrust. If all looks good, hold-down restraints will release to allow the New Glenn rocket to begin its ascent from Florida’s Space Coast.

Heading east, the rocket will surpass the speed of sound in a little over a minute. After soaring through the stratosphere, New Glenn will shut down its seven booster engines and shed its first stage a little more than 3 minutes into the flight. Twin BE-3U engines, burning liquid hydrogen, will ignite to finish the job of sending the ESCAPADE satellites toward deep space. The rocket’s trajectory will send the satellites toward a gravitationally-stable location beyond the Moon, called the L2 Lagrange point, where it will swing into a loosely-bound loiter orbit to wait for the right time to head for Mars.

Meanwhile, the New Glenn booster, itself measuring nearly 20 stories tall, will begin maneuvers to head toward Blue Origin’s recovery ship floating a few hundred miles downrange in the Atlantic Ocean. The final part of the descent will include a landing burn using three of the BE-4 engines, then downshifting to a single engine to control the booster’s touchdown on the landing platform, dubbed “Jacklyn” in honor of Bezos’ late mother.

New Glenn’s inaugural launch at the start of this year was a success, but the booster’s descent did not go well. The rocket was unable to restart its engines, and it crashed into the sea.

“We’ve incorporated a number of changes to our propellant management system, some minor hardware changes as well, to increase our likelihood of landing that booster on this mission,” said Laura Maginnis, Blue Origin’s vice president of New Glenn mission management. “That was the primary schedule driver that kind of took us from from January to where we are today.”

Blue Origin officials are hopeful they can land the booster this time. The company’s optimism is enough for officials to have penciled in a reflight of this particular booster on the very next New Glenn launch, slated for the early months of next year. That launch is due to send Blue Origin’s first Blue Moon cargo lander to the Moon.

“Our No. 1 objective is to deliver ESCAPADE safely and successfully on its way to L2, and then eventually on to Mars,” Maginnis said in a press conference Saturday. “We also are planning and wanting to land our booster. If we don’t land the booster, that’s OK. We have several more vehicles in production. We’re excited to see how the mission plays out tomorrow.”

Tracing a kidney bean

ESCAPADE’s path through space, relative to the Earth, has the peculiar shape of a kidney bean. In the world of astrodynamics, this is called a staging or libration orbit. It’s a way to keep the spacecraft on a stable trajectory to wait for the opportunity to go to Mars late next year.

“ESCAPADE has identified that this is the way that we want to fly, so we launch from Earth onto this kidney bean-shaped orbit,” said Jeff Parker, a mission designer from the Colorado-based company Advanced Space. “So, we can launch on virtually any day. What happens is that kidney bean just grows and shrinks based on how much time you need to spend in that orbit. So, we traverse that kidney bean and at the very end there’s a final little loop-the-loop that brings us down to Earth.”

That’s when the two ESCAPADE spacecraft, known as Blue and Gold, will pass a few hundred miles above our planet. At the right moment, on November 7 and 9 of next year, the satellites will fire their engines to set off for Mars.

There are some tradeoffs with this unique staging orbit. It is riskier than the original plan of sending ESCAPADE straight to Mars. The satellites will be exposed to more radiation, and will consume more of their fuel just to get to the red planet, eating into reserves originally set aside for science observations.

The satellites were built by Rocket Lab, which designed them with extra propulsion capacity in order to accommodate launches on a variety of different rockets. In the end, NASA “judged that the risk for the mission was acceptable, but it certainly is higher risk,” said Richard French, Rocket Lab’s vice president of business development and strategy.

The upside of the tradeoff is it will demonstrate an “exciting and flexible way to get to Mars,” Lillis said. “In the future, if we’d like to send hundreds of spacecraft to Mars at once, it will be difficult to do that from just the launch pads we have on Earth within that month [of the interplanetary launch window]. We could potentially queue up spacecraft using the approach that ESCAPADE is pioneering.”

Rocket Report: Canada invests in sovereign launch; India flexes rocket muscles


Europe’s Ariane 6 rocket gave an environmental monitoring satellite a perfect ride to space.

Welcome to Edition 8.18 of the Rocket Report! NASA is getting a heck of a deal from Blue Origin for launching the agency’s ESCAPADE mission to Mars. Blue Origin is charging NASA about $20 million for the launch on the company’s heavy-lift New Glenn rocket. A dedicated ride on any other rocket capable of the job would undoubtedly cost more.

But there are trade-offs. First, there’s the question of risk. The New Glenn rocket is only making its second flight, and it hasn’t been certified by NASA or the US Space Force. Second, the schedule for ESCAPADE’s launch has been at the whim of Blue Origin, which has delayed the mission several times due to issues developing New Glenn. NASA’s interplanetary missions typically have a fixed launch period, and the agency pays providers like SpaceX and United Launch Alliance a premium to ensure the launch happens when it needs to happen.

New Glenn is ready, the satellites are ready, and Blue Origin has set a launch date for Sunday, November 9. The mission will depart Earth outside of the usual interplanetary launch window, so orbital dynamics wizards came up with a unique trajectory that will get the satellites to Mars in 2027.

Canadian government backs launcher development. The federal budget released by the Liberal Party-led government of Canada this week includes a raft of new defense initiatives, including 182.6 million Canadian dollars ($129.4 million) for sovereign space launch capability, SpaceQ reports. The new funding is meant to “establish a sovereign space launch capability” with funds available this fiscal year and spent over three years. How the money will be spent and on what has yet to be released. As anticipated, Canada will have a new Defense Investment Agency (DIA) to oversee defense procurement. Overall, the government outlined 81.8 billion Canadian dollars ($58 billion) over five years for the Canadian Armed Forces. The Department of National Defense will manage the government’s cash infusion for sovereign launch capability.

Kick-starting an industry … Canada joins a growing list of nations pursuing homegrown launchers as many governments see access to space as key to national security and an opportunity for economic growth. International governments don’t want to be beholden to a small number of foreign launch providers from established space powers. That’s why startups in Germany, the United Kingdom, South Korea, and Australia are making a play in the launch arena, often with government support. A handful of Canadian startups, such as Maritime Launch Services, Reaction Dynamics, and NordSpace, are working on commercial satellite launchers. The Canadian government’s announcement came days after MDA Space, the largest established space company in Canada, announced its own multimillion-dollar investment in Maritime Launch Services.

Money alone won’t solve Europe’s space access woes. Increasing tensions with Russia have prompted defense spending boosts throughout Europe that will benefit fledgling smallsat launcher companies across the continent. But Europe is still years away from meeting its own space access needs, Space News reports. Space News spoke with industry analysts from two European consulting firms. They concluded that a lack of experience, not a deficit of money, is holding European launch startups back. None of the new crop of European rocket companies have completed a successful orbital flight.

Swimming in cash … The German company Isar Aerospace has raised approximately $600 million, the most funding of any of the European launch startups. Isar is also the only one of the bunch to make an orbital launch attempt. Its Spectrum rocket failed less than 30 seconds after liftoff last March, and a second launch is expected next year. Isar has attracted more investment than Rocket Lab, Firefly Aerospace, and Astra collectively raised on the private market before each of them successfully launched a rocket into orbit. In addition to Isar, several other European companies have raised more than $100 million on the road to developing a small satellite launcher. (submitted by EllPeaTea)

Successful ICBM test from Vandenberg. Air Force Global Strike Command tested an unarmed Minuteman III intercontinental ballistic missile in the predawn hours of Wednesday, Air and Space Forces Magazine reports. The test, the latest in a series of launches that have been carried out at regular intervals for decades, came as Russian President Vladimir Putin has touted the development of two new nuclear weapons and President Donald Trump has suggested in recent days that the US might resume nuclear testing. The ICBM launched from an underground silo at Vandenberg Space Force Base, California, and traveled some 4,200 miles to a test range in the Pacific Ocean after receiving launch orders from an airborne nuclear command-and-control plane.

Rehearsing for the unthinkable … The test, known as Glory Trip 254 (GT 254), provided a “comprehensive assessment” of the Minuteman III’s readiness to launch at a moment’s notice, according to the Air Force. “The data collected during the test is invaluable in ensuring the continued reliability and accuracy of the ICBM weapon system,” said Lt. Col. Karrie Wray, commander of the 576th Flight Test Squadron. For Minuteman III tests, the Air Force pulls its missiles from the fleet of some 400 operational ICBMs. This week’s test used one from F.E. Warren Air Force Base, Wyoming, and the missile was equipped with a single unarmed reentry vehicle that carried telemetry instrumentation instead of a warhead, service officials said.

One crew launches, another may be stranded. Three astronauts launched to China’s Tiangong space station on October 31 and arrived at the outpost a few hours later, extending the station’s four-year streak of continuous crew operations. The Shenzhou 21 crew spacecraft lifted off on a Chinese Long March 2F rocket from the Jiuquan space center in the Gobi Desert. Shenzhou 21 is supposed to replace a three-man crew that has been on the Tiangong station since April, but China’s Manned Space Agency announced Tuesday the outgoing crew’s return craft may have been damaged by space junk, Ars reports.

Few details … Chinese officials said the Shenzhou 20 spacecraft will remain at the station while engineers investigate the potential damage. As of Thursday, China has not set a new landing date or declared whether the spacecraft is safe to return to Earth at all. “The Shenzhou 20 manned spacecraft is suspected of being impacted by small space debris,” Chinese officials wrote on social media. “Impact analysis and risk assessment are underway. To ensure the safety and health of the astronauts and the complete success of the mission, it has been decided that the Shenzhou 20 return mission, originally scheduled for November 5, will be postponed.” In the event Shenzhou 20 is unsafe to return, China could launch a rescue craft—Shenzhou 22—already on standby at the Jiuquan space center.

Falcon 9 rideshare boosts Vast ambitions. A pathfinder mission for Vast’s privately owned space station launched into orbit Sunday and promptly extended its solar panel, kicking off a shakedown cruise to prove the company’s designs can meet the demands of spaceflight, Ars reports. Vast’s Haven Demo mission lifted off just after midnight Sunday from Cape Canaveral Space Force Station, Florida, and rode a SpaceX Falcon 9 rocket into orbit. Haven Demo was one of 18 satellites sharing a ride on SpaceX’s Bandwagon 4 mission, launching alongside a South Korean spy satellite and a small testbed for Starcloud, a startup working with Nvidia to build an orbital data center.

Subscale testing … After release from the Falcon 9, the half-ton Haven Demo spacecraft stabilized itself and extended its power-generating solar array. The satellite captured 4K video of the solar array deployment, and Vast shared the beauty shot on social media. “Haven Demo’s mission success has turned us into a proven spacecraft company,” Vast’s CEO, Max Haot, posted on X. “The next step will be to become an actual commercial space station company next year. Something no one has achieved yet.” Vast plans to launch its first human-rated habitat, named Haven-1, into low-Earth orbit in 2026. Haven Demo lacks crew accommodations but carries several systems that are “architecturally similar” to Haven-1, according to Vast. For example, Haven-1 will have 12 solar arrays, each identical to the single array on Haven Demo. The pathfinder mission uses a subset of Haven-1’s propulsion system, but with identical thrusters, valves, and tanks.

Lights out at Vostochny. One of Russia’s most important projects over the last 15 years has been the construction of the Vostochny spaceport as the country seeks to fly its rockets from native soil and modernize its launch operations. Progress has been slow as corruption clouded Vostochny’s development. Now, the primary contractor building the spaceport, the Kazan Open Stock Company (PSO Kazan), has failed to pay its bills, Ars reports. The story, first reported by the Moscow Times, says that the energy company supplying Vostochny cut off electricity to areas of the spaceport still under construction after PSO Kazan racked up $627,000 in unpaid energy charges. The electricity company did so, it said, “to protect the interests of the region’s energy system.”

A dark reputation … Officials at the government-owned spaceport said PSO Kazan would repay its debt by the end of November, but the local energy company said it intends to file a lawsuit against KSO Kazan to declare the entity bankrupt. The two operational launch pads at Vostochny are apparently not affected by the power cuts. Vostochny has been a fiasco from the start. After construction began in 2011, the project was beset by hunger strikes, claims of unpaid workers, and the theft of $126 million. Additionally, a man driving a diamond-encrusted Mercedes was arrested after embezzling $75,000. Five years ago, there was another purge of top officials after another round of corruption.

Ariane 6 delivers for Europe again. European launch services provider Arianespace has successfully launched the Sentinel 1D Earth observation satellite aboard an Ariane 62 rocket for the European Commission, European Spaceflight reports. Launched in its two-booster configuration, the Ariane 6 rocket lifted off from the Guiana Space Center in South America on Tuesday. Approximately 34 minutes after liftoff, the satellite was deployed from the rocket’s upper stage into a Sun-synchronous orbit at an altitude of 693 kilometers (430 miles). Sentinel 1D is the newest spacecraft to join Europe’s Copernicus program, the world’s most expansive network of environmental monitoring satellites. The new satellite will extend Europe’s record of global around-the-clock radar imaging, revealing information about environmental disasters, polar ice cover, and the use of water resources.

Doubling cadence … This was the fourth flight of Europe’s new Ariane 6 rocket, and its third operational launch. Arianespace plans one more Ariane 62 launch to close out the year with a pair of Galileo navigation satellites. The company aims to double its Ariane 6 launch cadence in 2026, with between six and eight missions planned, according to David Cavaillès, Arianespace’s CEO. The European launch provider will open its 2026 manifest with the first flight of the more powerful four-booster variant of the rocket. If the company does manage eight Ariane 6 flights in 2026, it will already be close to reaching the stated maximum launch cadence of between nine and 10 flights per year.

India sets its own record for payload mass. The Indian Space Research Organization on Sunday successfully launched the Indian Navy’s advanced communication satellite GSAT-7R, or CMS-03, on an LVM3 rocket from the Satish Dhawan Space Center, The Hindu reports. The indigenously designed and developed satellite, weighing approximately 4.4 metric tons (9,700 pounds), is the heaviest satellite ever launched by an Indian rocket and marks a major milestone in strengthening the Navy’s space-based communications and maritime domain awareness.

Going heavy … The launch Sunday was India’s fourth of 2025, a decline from the country’s high-water mark of eight orbital launches in a year in 2023. The failure in May of India’s most-flown rocket, the PSLV, has contributed to this year’s slower launch cadence. India’s larger rockets, the GSLV and LVM3, have been more active while officials grounded the PSLV for an investigation into the launch failure. (submitted by EllPeaTea)

Blue Origin preps for second flight of New Glenn. The road to the second flight of Blue Origin’s heavy-lifting New Glenn rocket got a lot clearer this week. The company confirmed it is targeting Sunday, November 9, for the launch of New Glenn from Cape Canaveral Space Force Station, Florida. This follows a successful test-firing of the rocket’s seven BE-4 main engines last week, Ars reports. Blue Origin, the space company owned by billionaire Jeff Bezos, said the engines operated at full power for 22 seconds, generating nearly 3.9 million pounds of thrust on the launch pad.

Fully integrated … With the launch date approaching, engineers worked this week to attach the rocket’s payload shroud containing two NASA satellites set to embark on a journey to Mars. Now that the rocket is fully integrated, ground crews will roll it back to Blue Origin’s Launch Complex-36 (LC-36) for final countdown preps. The launch window on Sunday opens at 2: 45 pm EST (19: 45 UTC). Blue Origin is counting on recovering the New Glenn first stage on the next flight after missing the landing on the rocket’s inaugural mission in January. Officials plan to reuse this booster on the third New Glenn launch early next year, slated to propel Blue Origin’s first unpiloted Blue Moon lander toward the Moon.

Next three launches

Nov. 8: Falcon 9 | Starlink 10-51 | Kennedy Space Center, Florida | 08: 30 UTC

Nov. 8: Long March 11H| Unknown Payload | Haiyang Spaceport, China Coastal Waters | 21: 00 UTC

Nov. 9: New Glenn | ESCAPADE | Cape Canaveral Space Force Station, Florida | 19: 45 UTC

the-government-shutdown-is-starting-to-have-cosmic-consequences

The government shutdown is starting to have cosmic consequences

The federal government shutdown, now in its 38th day, prompted the Federal Aviation Administration to issue a temporary emergency order Thursday prohibiting commercial rocket launches from occurring during “peak hours” of air traffic.

The FAA also directed commercial airlines to reduce domestic flights from 40 “high impact airports” across the country in a phased approach beginning Friday. The agency said the order from the FAA’s administrator, Bryan Bedford, is aimed at addressing “safety risks and delays presented by air traffic controller staffing constraints caused by the continued lapse in appropriations.”

The government considers air traffic controllers essential workers, so they remain on the job without pay until Congress passes a federal budget and President Donald Trump signs it into law. The shutdown’s effects, which affected federal workers most severely at first, are now rippling across the broader economy.

Sharing the airspace

Vehicles traveling to and from space share the skies with aircraft, requiring close coordination with air traffic controllers to clear airspace for rocket launches and reentries. The FAA said its order restricting commercial air traffic, launches, and reentries is intended to “ensure the safety of aircraft and the efficiency of the [National Airspace System].”

In a statement explaining the order, the FAA said the air traffic control system is “stressed” due to the shutdown.

“With continued delays and unpredictable staffing shortages, which are driving fatigue, risk is further increasing, and the FAA is concerned with the system’s ability to maintain the current volume of operations,” the regulator said. “Accordingly, the FAA has determined additional mitigation is necessary.”

Beginning Monday, the FAA said commercial space launches will only be permitted between 10 pm and 6 am local time, when the national airspace is most calm. The order restricts commercial reentries to the same overnight timeframe. The FAA licenses all commercial launches and reentries.

SpaceX teases simplified Starship as alarms sound over Moon landing delays


“SpaceX shares the goal of returning to the Moon as expeditiously as possible.”

SpaceX on Thursday released the most detailed public update in nearly two years on its multibillion-dollar contract to land astronauts on the Moon for NASA, amid growing sentiment that China is likely to beat the United States back to the lunar surface with humans.

In a lengthy statement published on SpaceX’s website Thursday, the company said it “will be a central enabler that will fulfill the vision of NASA’s Artemis program, which seeks to establish a lasting presence on the lunar surface… and ultimately forge the path to land the first humans on Mars.”

Getting to Mars is SpaceX’s overarching objective, a concise but lofty mission statement introduced by Elon Musk at the company’s founding nearly a quarter-century ago. Musk has criticized NASA’s Artemis program, which aims to return US astronauts to the Moon for the first time since the last Apollo lunar mission in 1972, as unambitious and too reliant on traditional aerospace contractors.

Is this a priority for SpaceX?

The Starship rocket and its massive Super Heavy booster are supposed to be SpaceX’s solution for fulfilling Musk’s mission of creating a settlement on Mars. The red planet has been the focus each time Musk has spoken at length about Starship in the last couple of years, with Moon missions receiving little or no time in his comments, whether they’re scripted or off the cuff.

In the background, SpaceX’s engineers have been busy developing a version of the Starship rocket to fly crews to and from the surface of the Moon for NASA. The agency’s current architecture calls for astronauts to transit from the Earth to the vicinity of the Moon inside NASA’s Orion spacecraft, made by Lockheed Martin, then link up with Starship in lunar orbit for a ride to the Moon’s south pole.

After completing their mission on the surface, the astronauts will ride Starship back into space and dock with Orion to bring them home. Starship and Orion may also link together by docking at the planned Gateway mini-space station orbiting the Moon, but Gateway’s future is in question as NASA faces budget cuts.

NASA has contracts with SpaceX valued at more than $4 billion to land two astronaut crews on the Moon on NASA’s Artemis III and Artemis IV missions. The contract also covers milestones ahead of any human mission, such as an uncrewed Starship landing and takeoff at the Moon, to prove the vehicle is ready.

The fresh update from SpaceX lists recent achievements the company has accomplished on the path to the Moon, including demos of life support and thermal control systems, the docking adapter to link Starship with Orion, navigation hardware and software, a landing leg structural test, and engine firings in conditions similar to what the ship will see at the Moon.

Many of these milestones were completed ahead of schedule, SpaceX said. But the biggest tests, such as demonstrating in-orbit refueling, remain ahead. Some NASA officials believe mastering orbital refueling will take many tries, akin to SpaceX’s iterative two steps forward, one step back experience with its initial Starship test flights.

The first test to transfer large amounts of cryogenic liquid methane and liquid oxygen between two Starships in low-Earth orbit is now planned for next year. This time a year ago, SpaceX aimed to launch the first orbital refueling demo before the end of 2025.

Orbital refueling is key to flying Starship to the Moon or Mars. The rocket consumes all of its propellant getting to low-Earth orbit, and it needs more gas to go farther. For lunar missions, SpaceX will launch a Starship-derived propellant depot into orbit, refill it with perhaps a dozen or more Starship tankers, and then dock the Starship lander with it to load its tanks before heading off to the Moon.

Officials haven’t given a precise number of tanker flights required for a Starship lunar lander. It’s likely engineers won’t settle on an exact number until they obtain data on how much of the super-cold liquid propellant boils off in space, and how efficient it is to transfer from ship to ship. Whatever the number, SpaceX says Starship’s design for recovery and rapid reuse will facilitate a fast-paced launch and refueling campaign.

The upshot of overcoming the refueling hurdle is Starship’s promise of becoming a transformative vehicle. Starship is enormous compared to any other concept for landing on the Moon. One single Starship has a pressurized habitable volume of more than 600 cubic meters, or more than 21,000 cubic feet, roughly two-thirds that of the entire International Space Station, according to SpaceX. Starship will have dual airlocks, or pathways for astronauts and equipment to exit and enter the spacecraft.

An elevator will lower people and cargo down to the lunar surface from the crew cabin at the top of the 15-story-tall spacecraft. For pure cargo missions, SpaceX says Starship will be capable of landing up to 100 metric tons of cargo directly on the Moon’s surface. This would unlock the ability to deliver large rovers, nuclear reactors, or lunar habitats to the Moon in one go. In the long run, the Starship architecture could allow landers to be reused over and over again. All of this is vital if NASA wants to build a permanent base or research outpost on the Moon.

A competition in more ways than one

But hard things take time. SpaceX dealt with repeated setbacks in the first half of this year: three in-flight failures of Starship and one Starship explosion on the ground at the company’s development facility in South Texas. Since then, teams have reeled off consecutive successful Starship test flights ahead of the debut of an upgraded Starship variant called Version 3 in the coming months. Starship Version 3 will have the accoutrements for refueling, and SpaceX says this will also be the version to fly to the Moon.

The recent Starship delays, coupled with the scope of work to go, have raised concerns that the Artemis program is falling behind China’s initiative to land its own astronauts on the Moon. China’s goal is to do it by 2030, a schedule reiterated in Chinese state media this week. The Chinese program relies on an architecture more closely resembling NASA’s old Apollo designs.

The official schedule for the first Artemis crew landing, on Artemis III, puts it in 2027, but that timeline is no longer achievable. Starship and new lunar spacesuits developed by Axiom Space won’t be ready, in part because NASA didn’t award the contracts to SpaceX and Axiom until 2021 and 2022.

All of this adds up to waning odds that the United States can beat China back to the Moon, according to a growing chorus of voices in the space community. Last month, former NASA chief Jim Bridenstine, who led the agency during the first Trump administration, told Congress the United States was likely to lose the second lunar space race.

At a space conference earlier this week, Bridenstine suggested the Trump administration use its powers to fast-track a lunar landing, even floating the idea of invoking the Defense Production Act, a law that grants the president authority to marshal industrial might to meet pressing national needs.

An executive order from President Donald Trump could authorize such an effort and declare a “national security imperative that we’re going to beat China to the Moon,” Bridenstine said at the American Astronautical Society’s von Braun Space Exploration Symposium in Huntsville, Alabama.

Charlie Bolden, NASA’s administrator under former President Barack Obama, also expressed doubts that NASA could land humans on the Moon before China, or by the end of Trump’s term in the White House. “Let’s be real, OK? Everybody in this room knows, to say we’re going to do it by the end of the term, or we’re going to do it before the Chinese, that doesn’t help industry.”

But Bolden said maybe it’s not so terrible if China lands people on the Moon before NASA can return with astronauts. “We may not make 2030, and that’s OK with me, as long as we get there in 2031 better than they are with what they have there.”

Sean Duffy, NASA’s acting administrator, doesn’t see it the same way. Duffy said last week he would give contractors until this Wednesday to propose other ways of landing astronauts on the Moon sooner than the existing plan. SpaceX and Blue Origin, the space company founded by billionaire Jeff Bezos, confirmed they submitted updated plans to NASA this week.

Blue Origin has a separate contract with NASA to provide its own human-rated lunar lander—Blue Moon Mark 2—for entry into service on the Artemis V mission, likely not to occur before the early 2030s. A smaller unpiloted lander—Blue Moon Mark 1—is on track to launch on Blue Origin’s first lunar landing attempt next year.

Blue Moon Mark 1 is still a big vehicle, standing taller than the lunar lander used by NASA during the Apollo program. But it doesn’t match the 52-foot (16-meter) height of Blue Origin’s Mark 2 lander, and tops out well short of the roughly 165-foot-tall (50-meter) Starship lander.

What’s more, Blue Moon Mark 1 won’t need to be refueled after launch, unlike Starship and Mark 2. Jacki Cortese, senior director of civil space at Blue Origin, confirmed Tuesday that her company is looking at employing a “more incremental approach” using Mark 1 to accelerate an Artemis crew landing. Ars first reported Blue Origin was studying how to modify Blue Moon Mark 1 for astronauts.

All of this is a reminder of something Blue Origin said in 2021, when NASA passed over Bezos’ company to award the first Artemis lander contract to SpaceX. Blue Origin protested the award and filed a lawsuit against the government, triggering a lunar lander work stoppage that lasted several months until a federal judge dismissed the suit.

Blue Origin said SpaceX’s approach with numerous refueling sorties was “immensely complex and high risk” and argued its proposal was the better option for NASA. The statement has taken on a meme-worthy status among fans of Starship.

But SpaceX bid a lower cost, and NASA officials said it was the only proposal the agency could afford at the time. And then, when Blue Origin won a contract from NASA in 2023 to provide a second lander option, the company’s concept also hinged on refueling the Blue Moon Mark 2 lander in space.

Now, SpaceX is making a new offering to NASA. Like Blue Origin, SpaceX said it has sent in a proposal for a “simplified architecture” for landing astronauts on the Moon, but did not provide details.

“We’ve shared and are formally assessing a simplified mission architecture and concept of operations that we believe will result in a faster return to the Moon while simultaneously improving crew safety,” the company said.

Since NASA selected SpaceX for the Human Landing System contract in 2021, the company said it has been “consistently responsive to NASA as requirements for Artemis III have changed.”

For example, NASA originally required SpaceX to only demonstrate it could land Starship on the Moon before moving forward with a crew mission. Lori Glaze, who leads NASA’s human exploration division, said in July that the agency is now requiring the uncrewed landing demo to also include an ascent from the Moon’s surface. NASA wants to know if Starship can not just land astronauts on the Moon, but also get them back.

“Starship continues to simultaneously be the fastest path to returning humans to the surface of the Moon and a core enabler of the Artemis program’s goal to establish a permanent, sustainable presence on the lunar surface,” SpaceX said. “SpaceX shares the goal of returning to the Moon as expeditiously as possible, approaching the mission with the same alacrity and commitment that returned human spaceflight capability to America under NASA’s Commercial Crew program.”

SpaceX has built a reputation for doing things quickly. One example has been the rapid-fire launch cadence of the company’s workhorse Falcon 9 rocket. SpaceX is setting up launch pads and factories to manufacture and launch Super Heavy and Starshipcombining together to make the largest rocket ever built—at an even faster rate than Falcon 9.

The company has launched 11 full-scale test flights of Starship/Super Heavy since April 2023. “This campaign has quickly matured the core Starship and has produced numerous feats,” SpaceX said. The company listed some of them:

  • Multiple successful ascents of the world’s most powerful rocket
  • The launch, return, catch, and reuse of that rocket to unlock the high launch rate cadence needed for lunar missions
  • The transfer of approximately 5 metric tons of cryogenic propellant between tanks while in space
  • Successful in-space relights of the Raptor engines that are critical for the maneuvers that will send Starship to the Moon
  • Multiple controlled reentries through Earth’s atmosphere

It’s true that these feats have come fast. Many more remain on the road ahead before SpaceX can make good on its commitment to NASA.

New Glenn rocket has clear path to launch after test-firing at Cape Canaveral

The road to the second flight of Blue Origin’s heavy-lifting New Glenn rocket got a lot clearer Thursday night with a success test-firing of the launcher’s seven main engines on a launch pad at Cape Canaveral Space Force Station, Florida.

Standing on a seaside launch pad, the New Glenn rocket ignited its seven BE-4 main engines at 9: 59 pm EDT Thursday (01: 59 UTC Friday). The engines burned for 38 seconds while the rocket remained firmly on the ground, according to a social media post by Blue Origin.

The hold-down firing of the first stage engines was the final major test of the New Glenn rocket before launch day. Blue Origin previously test-fired the rocket’s second-stage engines. Officials have not announced a target launch date, but sources tell Ars the rocket could be ready for liftoff as soon as November 9.

“Love seeing New Glenn’s seven BE-4 engines come alive! Congratulations to Team Blue on today’s hotfire,” the company’s CEO, Dave Limp, posted on X.

Blue Origin, the space company owned by billionaire Jeff Bezos, said the engines operated at full power for 22 seconds, generating nearly 3.9 million pounds of thrust. Limp said engineers extended this test-firing and shut down some of the BE-4 engines to simulate the booster’s landing burn sequence, which Blue Origin hopes will culminate in a successful touchdown on a barge floating downrange in the Atlantic Ocean.

“This helps us understand fluid interactions between active and inactive engine feedlines during landing,” Limp wrote.

Blue Origin is counting on recovering the New Glenn first stage on the next flight after missing the landing on the rocket’s inaugural mission in January. Officials plan to reuse this booster on the third New Glenn launch early next year, slated to propel Blue Origin’s first unpiloted Blue Moon lander toward the Moon. If Blue Origin fails to land this rocket, it’s unlikely a new first stage booster will be ready to launch until sometime later in 2026.

A few more things to do

With the test-firing complete, Blue Origin’s ground crew will lower the more than 320-foot-tall (98-meter) rocket and roll it back to a nearby hangar. There, technicians will inspect the vehicle and swap its payload fairing for another clamshell containing two NASA-owned spacecraft set to begin their journey to Mars.

Rocket Report: China tests Falcon 9 lookalike; NASA’s Moon rocket fully stacked


A South Korean rocket startup will soon make its first attempt to reach low-Earth orbit.

The Orion spacecraft for the Artemis II mission is lowered on top of the Space Launch System rocket at Kennedy Space Center, Florida.

Welcome to Edition 8.16 of the Rocket Report! The 10th anniversary of SpaceX’s first Falcon 9 rocket landing is coming up at the end of this year. We’re still waiting for a second company to bring back an orbital-class booster from space for a propulsive landing. Two companies, Jeff Bezos’ Blue Origin and China’s LandSpace, could join SpaceX’s exclusive club as soon as next month. (Bezos might claim he’s already part of the club, but there’s a distinction to be made.) Each company is in the final stages of launch preparations—Blue Origin for its second New Glenn rocket, and LandSpace for the debut flight of its Zhuque-3 rocket. Blue Origin and LandSpace will both attempt to land their first stage boosters downrange from their launch sites. They’re not exactly in a race with one another, but it will be fascinating to see how New Glenn and Zhuque-3 perform during the uphill and downhill phases of flight, and whether one or both of the new rockets stick the landing.

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.

The race for space-based interceptors. The Trump administration’s announcement of the Golden Dome missile defense shield has set off a race among US companies to develop and test space weapons, some of them on their own dime, Ars reports. One of these companies is a 3-year-old startup named Apex, which announced plans to test a space-based interceptor as soon as next year. Apex’s concept will utilize one of the company’s low-cost satellite platforms outfitted with an “Orbital Magazine” containing multiple interceptors, which will be supplied by an undisclosed third-party partner. The demonstration in low-Earth orbit could launch as soon as June 2026 and will test-fire two interceptors from Apex’s Project Shadow spacecraft. The prototype interceptors could pave the way for operational space-based interceptors to shoot down ballistic missiles. (submitted by biokleen)

Usual suspects … Traditional defense contractors are also getting in the game. Northrop Grumman’s CEO, Kathy Warden, said earlier this year that her company is already testing space-based interceptor components on the ground. This week, Lockheed Martin announced it is on a path to test a space-based interceptor in orbit by 2028. Neither company has discussed as much detail of their plans as Apex revealed this week.

Lockheed Martin’s latest “New Space” investment. As interest grows in rotating detonation engines for hypersonic flight, a startup specialist in the technology says it will receive backing from Lockheed Martin’s corporate venture capital arm, Aviation Week & Space Technology reports. The strategic investment by Lockheed Martin Ventures “reflects the potential of Venus’s dual-use technology” in an era of growing defense and space spending, Venus Aerospace said in a statement. Venus said its partnership with Lockheed Martin combines the former’s startup mindset with the latter’s resources and industry expertise. The companies did not announce the value of Lockheed’s investment, but Venus said it has raised $106 million since its founding in 2020. Lockheed Martin Ventures has made similar investments in other rocket startups, including Rocket Lab in 2015.

What’s this actually for? … Houston-based Venus Aerospace completed a high-thrust test flight of its Rotating Detonation Rocket Engine (RDRE) in May from Spaceport America, New Mexico. Rotating detonation engine technology is interesting because it has the potential to significantly increase fuel efficiency in various applications, from Navy carriers to rocket engines, Ars reported earlier this year. The engine works by producing a shockwave with a flow of detonation traveling through a circular channel. The engine harnesses these supersonic detonation waves to generate thrust. “Venus has proven in flight the most efficient rocket engine technology in history,” said Sassie Duggleby, co-founder and CEO of Venus Aerospace. “With support from Lockheed Martin Ventures, we will advance our capabilities to deliver at scale and deploy the engine that will power the next 50 years of defense, space, and commercial high-speed aviation.”

South Korean startup receives permission to fly. Innospace announced on October 20 that it has received South Korea’s first private commercial launch permit from the Korea AeroSpace Administration,” the Chosun Daily reports. Accordingly, Innospace will launch its independently developed “HANBIT-Nano” launch vehicle from a Brazilian launch site as early as late this month. Innospace stated that the launch window for this mission has been set for October 28 through November 28. The launch site is the Alcântara Space Center, operated by the Brazilian Air Force.

Aiming for LEO … This will be the first flight of Innospace’s HANBIT-Nano launch vehicle, standing roughly 72 feet (22 meters) tall with a diameter of 4.6 feet (1.4 meters). The two-stage rocket is powered by hybrid propulsion, consuming a mixture of paraffin and liquid oxygen. For its debut flight, the rocket will target an orbit about 300 kilometers (186 miles) high with a batch of small satellites from customers in South Korea, Brazil, and India. According to Innospace, HANBIT-Nano can lift about 200 pounds (90 kilograms) of payload into orbit.

A new record for rocket reuse. SpaceX’s launch of a Falcon 9 rocket from Florida on October 19 set a new record for reusable rockets, Ars reports. It marked the 31st launch of the company’s most-flown Falcon 9 booster. The rocket landed on SpaceX’s recovery ship in the Atlantic Ocean to be returned to Florida for a 32nd flight. Several more rockets in SpaceX’s inventory are nearing their 30th launch. In all, SpaceX has more than 20 Falcon 9 boosters in its fleet on both the East and West Coasts. SpaceX engineers are now certifying the Falcon 9 boosters for up to 40 flights apiece.

10,000 and counting … SpaceX’s two launches last weekend weren’t just noteworthy for Falcon 9 lore. Hours after setting the new booster reuse record, SpaceX deployed a batch of 28 Starlink satellites from a different rocket after lifting off from California. This mission propelled SpaceX’s Starlink program past a notable milestone. With the satellites added to the constellation on Sunday, the company has delivered more than 10,000 mass-produced Starlink spacecraft to low-Earth orbit. The exact figure stands at 10,006 satellites, according to a tabulation by Jonathan McDowell, an astrophysicist who expertly tracks comings and goings between Earth and space. About 8,700 of these Starlink satellites are still in orbit, with SpaceX adding more every week.

China is on the cusp of something big. Launch startup LandSpace is in the final stages of preparations for the first flight of its Zhuque-3 rocket and a potentially landmark mission for China, Space News reports. LandSpace said it completed the first phase of the Zhuque-3 rocket’s inaugural launch campaign this week. The Zhuque-3 is the largest commercial rocket developed to date in China, nearly matching the size and performance of SpaceX’s Falcon 9, with nine first stage engines and a single upper stage engine. One key difference is that the Zhuque-3 burns methane fuel, while Falcon 9’s engines consume kerosene. Most notably, LandSpace will attempt to land the rocket’s first stage booster at a location downrange from the launch site, similar to the way SpaceX lands Falcon 9 boosters on drone ships at sea. Zhuque-3’s first stage will aim for a land-based site in an experiment that could pave the way for LandSpace to reuse rockets in the future.

Testing status … The recent testing at Jiuquan Satellite Launch Center in northwestern China included a propellant loading demonstration and a static fire test of the rocket’s first stage engines. Earlier this week, LandSpace integrated the payload fairing on the rocket. The company said it will return the rocket to a nearby facility “for inspection and maintenance in preparation for its upcoming orbital launch and first stage recovery.” The launch is expected to happen as soon as next month.

Uprated Ariane 6 won’t launch until next year. Arianespace has confirmed that the first flight of the more powerful, four-booster variant of the Ariane 6 rocket will not be launched until 2026, European Spaceflight reports. The first Ariane 64 rocket had been expected to launch in late 2025, carrying the first batch of Amazon’s Project Kuiper satellites. On October 16, Arianespace announced the fourth and final Ariane 6 flight of the year would carry a pair of Galileo satellites for Europe’s global satellite navigation system in December. This will follow an already-scheduled Ariane 6 launch scheduled for November 4. Both of the upcoming flights will employ the same Ariane 6 configuration used on all of the rocket’s flights to date. This version, known as Ariane 62, has two strap-on solid rocket boosters.

Kuiper soon … The Ariane 64 variant will expose the rocket to stronger forces coming from four solid rocket boosters, each producing about a million pounds (4,500 kilonewtons) of thrust. ArianeGroup, the rocket’s manufacturer, said a year ago that it completed qualification of the Ariane 6 upper stage to withstand the stronger launch loads. Arianespace didn’t offer any explanation of the Ariane 64’s delay from this year to next, but it did confirm the uprated rocket will be the company’s first flight of 2026. The mission will be the first of 18 Arianespace flights dedicated to launching Amazon’s Project Kuiper broadband satellites, adding Ariane 6 to the mix of rockets deploying the Internet network in low-Earth orbit.

Duffy losing confidence in Starship. NASA acting Administrator Sean Duffy made two television appearances on Monday morning in which he shook up the space agency’s plans to return humans to the Moon, Ars reports. Speaking on Fox News, where the secretary of transportation frequently appears in his acting role as NASA chief, Duffy said SpaceX has fallen behind in developing the Starship vehicle as a lunar lander. Duffy also indirectly acknowledged that NASA’s projected target of a 2027 crewed lunar landing is no longer achievable. Accordingly, he said he intended to expand the competition to develop a lander capable of carrying humans down to the Moon from lunar orbit and back.

The rest of the story … “They’re behind schedule, and so the President wants to make sure we beat the Chinese,” Duffy said of SpaceX. “He wants to get there in his term. So I’m in the process of opening that contract up. I think we’ll see companies like Blue [Origin] get involved, and maybe others. We’re going to have a space race in regard to American companies competing to see who can actually lead us back to the Moon first.” The timing of Duffy’s public appearances on Monday seems tailored to influence a fierce, behind-the-scenes battle to hold onto the NASA leadership position. Jared Isaacman, who Trump nominated and then withdrew for the NASA posting, is again under consideration at the White House to become the agency’s next full-time administrator.

Rocket fully stacked for Artemis II. The last major hardware component before Artemis II launches early next year has been installed,” NASA’s acting Administrator Sean Duffy posted on X Monday. Over the weekend, ground teams at Kennedy Space Center in Florida hoisted the Orion spacecraft for the Artemis II mission atop its Space Launch System rocket inside the Vehicle Assembly Building. This followed the transfer of the Orion spacecraft to the VAB from a nearby processing facility last week. With Orion installed, the rocket is fully assembled to its complete height of 322 feet (98 meters) tall.

Four months away? … NASA is still officially targeting no earlier than February 5, 2026, for the launch of the Artemis II mission. This will be the first flight of astronauts to the vicinity of the Moon since 1972, and the first glimpse of human spaceflight beyond low-Earth orbit for several generations. Upcoming milestones in the Artemis II launch campaign include a countdown demonstration inside the VAB, where the mission’s four-person crew will take their seats in the Orion spacecraft to simulate what they’ll go through on launch day.

New Glenn staged for rollout. Dave Limp, Blue Origin’s CEO, posted a video this week of the company’s second New Glenn rocket undergoing launch preparations inside a hangar at Launch Complex 36 at Cape Canaveral, Florida. The rocket’s first and second stages are now mated together and installed on the transporter erector that will carry them from the hangar to the launch pad. “We will spend the next days on final checkouts and connecting the umbilicals. Stay tuned for rollout and hotfire!” Limp wrote.

“Big step toward launch” … The connection of New Glenn’s stages and integration on the transporter erector marks a “big step toward launch,” Limp wrote. A launch sometime in November is still possible if engineers can get through a smooth test-firing of the rocket’s seven main engines on the launch pad. The rocket will send two NASA spacecraft on a journey to Mars.

China launches clandestine satellite. China launched a Long March 5 rocket Thursday with a classified military satellite heading toward geosynchronous orbit, Space News reports. The satellite is named TJS-20, and the circumstances of the launch—using China’s most powerful operational rocket—suggest TJS-20 could be the next in a line of signals intelligence-gathering missions. The previous satellite of this line, TJS-11, launched in February 2024, also on a Long March 5.

Doing a lot … This launch continued China’s increasing use of the Long March 5 and its sister variant, the Long March 5B. The Long March 5 is expendable, and although we don’t know how much it costs, it can’t be cheap. It is a complex rocket powered by 10 engines on its core stage and four boosters, some burning liquid hydrogen fuel and others burning kerosene. The second stage also has two cryogenically fueled engines. The Long March 5 has now flown 16 times in nine years and seven times within the last two years. The uptick in launches is largely due to China’s use of the Long March 5 to launch satellites for the Guowang megaconstellation.

NASA’s next Moonship reaches last stop before launch pad

The Orion spacecraft, which will fly four people around the Moon, arrived inside the cavernous Vehicle Assembly Building at NASA’s Kennedy Space Center in Florida late Thursday night, ready to be stacked on top of its rocket for launch early next year.

The late-night transfer covered about 6 miles (10 kilometers) from one facility to another at the Florida spaceport. NASA and its contractors are continuing preparations for the Artemis II mission after the White House approved the program as an exception to work through the ongoing government shutdown, which began on October 1.

The sustained work could set up Artemis II for a launch opportunity as soon as February 5 of next year. Astronauts Reid Wiseman, Victor Glover, Christina Koch, and Jeremy Hansen will be the first humans to fly on the Orion spacecraft, a vehicle that has been in development for nearly two decades. The Artemis II crew will make history on their 10-day flight by becoming the first people to travel to the vicinity of the Moon since 1972.

Where things stand

The Orion spacecraft, developed by Lockheed Martin, has made several stops at Kennedy over the last few months since leaving its factory in May.

First, the capsule moved to a fueling facility, where technicians filled it with hydrazine and nitrogen tetroxide propellants, which will feed Orion’s main engine and maneuvering thrusters on the flight to the Moon and back. In the same facility, teams loaded high-pressure helium and ammonia coolant into Orion propulsion and thermal control systems.

The next stop was a nearby building where the Launch Abort System was installed on the Orion spacecraft. The tower-like abort system would pull the capsule away from its rocket in the event of a launch failure. Orion stands roughly 67 feet (20 meters) tall with its service module, crew module, and abort tower integrated together.

Teams at Kennedy also installed four ogive panels to serve as an aerodynamic shield over the Orion crew capsule during the first few minutes of launch.

It was then time to move Orion to the Vehicle Assembly Building (VAB), where a separate team has worked all year to stack the elements of NASA’s Space Launch System rocket. In the coming days, cranes will lift the spacecraft, weighing 78,000 pounds (35 metric tons), dozens of stories above the VAB’s center aisle, then up and over the transom into the building’s northeast high bay to be lowered atop the SLS heavy-lift rocket.

SpaceX has plans to launch Falcon Heavy from California—if anyone wants it to

There’s more to the changes at Vandenberg than launching additional rockets. The authorization gives SpaceX the green light to redevelop Space Launch Complex 6 (SLC-6) to support Falcon 9 and Falcon Heavy missions. SpaceX plans to demolish unneeded structures at SLC-6 (pronounced “Slick 6”) and construct two new landing pads for Falcon boosters on a bluff overlooking the Pacific just south of the pad.

SpaceX currently operates from a single pad at Vandenberg—Space Launch Complex 4-East (SLC-4E)—a few miles north of the SLC-6 location. The SLC-4E location is not configured to launch the Falcon Heavy, an uprated rocket with three Falcon 9 boosters bolted together.

SLC-6, cocooned by hills on three sides and flanked by the ocean to the west, is no stranger to big rockets. It was first developed for the Air Force’s Manned Orbiting Laboratory program in the 1960s, when the military wanted to put a mini-space station into orbit for astronauts to spy on the Soviet Union. Crews readied the complex to launch military astronauts on top of Titan rockets, but the Pentagon canceled the program in 1969 before anything actually launched from SLC-6.

NASA and the Air Force then modified SLC-6 to launch space shuttles. The space shuttle Enterprise was stacked vertically at SLC-6 for fit checks in 1985, but the Air Force abandoned the Vandenberg-based shuttle program after the Challenger accident in 1986. The launch facility sat mostly dormant for nearly two decades until Boeing, and then United Launch Alliance, took over SLC-6 and began launching Delta IV rockets there in 2006.

ULA launched its last Delta IV Heavy rocket from California in 2022, leaving the future of SLC-6 in question. ULA’s new rocket, the Vulcan, will launch from a different pad at Vandenberg. Space Force officials selected SpaceX in 2023 to take over the pad and prepare it to launch the Falcon Heavy, which has the lift capacity to carry the military’s most massive satellites into orbit.

No big rush

Progress at SLC-6 has been slow. It took nearly a year to prepare the Environmental Impact Statement. In reality, there’s no big rush to bring SLC-6 online. SpaceX has no Falcon Heavy missions from Vandenberg in its contract backlog, but the company is part of the Pentagon’s stable of launch providers. To qualify as a member of the club, SpaceX must have the capability to launch the Space Force’s heaviest missions from the military’s spaceports at Vandenberg and Cape Canaveral, Florida.

starship’s-elementary-era-ends-today-with-mega-rocket’s-11th-test-flight

Starship’s elementary era ends today with mega-rocket’s 11th test flight

Future flights of Starship will end with returns to Starbase, where the launch tower will try to catch the vehicle coming home from space, similar to the way SpaceX has shown it can recover the Super Heavy booster. A catch attempt with Starship is still at least a couple of flights away.

In preparation for future returns to Starbase, the ship on Flight 11 will perform a “dynamic banking maneuver” and test subsonic guidance algorithms prior to its final engine burn to brake for splashdown. If all goes according to plan, the flight will end with a controlled water landing in the Indian Ocean approximately 66 minutes after liftoff.

Turning point

Monday’s test flight will be the last Starship launch of the year as SpaceX readies a new generation of the rocket, called Version 3, for its debut sometime in early 2026. The new version of the rocket will fly with upgraded Raptor engines and larger propellant tanks and have the capability for refueling in low-Earth orbit.

Starship Version 3 will also inaugurate SpaceX’s second launch pad at Starbase, which has several improvements over the existing site, including a flame trench to redirect engine exhaust away from the pad. The flame trench is a common feature of many launch pads, but all of the Starship flights so far have used an elevated launch mount, or stool, over a water-cooled flame deflector.

The current launch complex is expected to be modified to accommodate future Starship V3s, giving the company two pads to support a higher flight rate.

NASA is counting on a higher flight rate for Starship next year to move closer to fulfilling SpaceX’s contract to provide a human-rated lander to the agency’s Artemis lunar program. SpaceX has contracts worth more than $4 billion to develop a derivative of Starship to land NASA astronauts on the Moon.

But much of SpaceX’s progress toward a lunar landing hinges on launching numerous Starships—perhaps a dozen or more—in a matter of a few weeks or months. SpaceX is activating the second launch pad in Texas and building several launch towers and a new factory in Florida to make this possible.

Apart from recovering and reusing Starship itself, the program’s most pressing near-term hurdle is the demonstration of in-orbit refueling, a prerequisite for any future Starship voyages to the Moon or Mars. This first refueling test could happen next year but will require Starship V3 to have a smoother introduction than Starship V2, which is retiring after Flight 11 with, at best, a 40 percent success rate.

putin-oks-plan-to-turn-russian-spacecraft-into-flying-billboards

Putin OKs plan to turn Russian spacecraft into flying billboards

These are tough times for Russia’s civilian space program. In the last few years, Russia has cut back on the number of Soyuz crew missions it is sending to the International Space Station, and a replacement for the nearly 60-year-old Soyuz spacecraft remains elusive.

While the United States and China are launching more space missions than ever before, Russia’s once-dominant launch cadence is on a downhill slide.

Russia’s access to global markets dried up after Russian President Vladimir Putin launched the country’s invasion of Ukraine in February 2022. The fallout from the invasion killed several key space partnership between Russia and Europe. Russia’s capacity to do new things in space seems to be focused on military programs like anti-satellite weapons.

The Roscosmos State Corporation for Space Activities, Russia’s official space agency, may have a plan to offset the decline. Late last month, Putin approved changes to federal laws governing advertising and space activities to “allow for the placement of advertising on spacecraft,” Roscosmos posted on its official Telegram account.

We’ve seen this before

The Russian State Duma, dominated by Putin loyalists, previously approved the amendments.

“According to the amendments, Roscosmos has been granted the right, effective January 1, 2026, to place advertising on space objects owned by both the State Corporation itself and federally,” Roscosmos said. “The amendments will create a mechanism for attracting private investment in Russian space exploration and reduce the burden on the state budget.”

The law requires that advertising symbols not affect spacecraft safety. The Russian government said it will establish a fee structure for advertising on federally owned space objects.

Roscosmos didn’t say this, but advertisers eligible for the offer will presumably be limited to Russia and its allies. Any ads from the West would likely violate sanctions.

Rocket-makers have routinely applied decals, stickers, and special paint jobs to their vehicles. This is a particularly popular practice in Russia. Usually, these logos represent customers and suppliers. Sometimes they honor special occasions, like the 60th anniversary of the first human spaceflight mission by Soviet cosmonaut Yuri Gagarin and the 80th anniversary of the end of World War II.

Pentagon contract figures show ULA’s Vulcan rocket is getting more expensive

The launch orders announced Friday comprise the second batch of NSSL Phase 3 missions the Space Force has awarded to SpaceX and ULA.

It’s important to remember that these prices aren’t what ULA or SpaceX would charge a commercial satellite customer. The US government pays a premium for access to space. The Space Force, the National Reconnaissance Office, and NASA don’t insure their launches like a commercial customer would do. Instead, government agencies have more insight into their launch contractors, including inspections, flight data reviews, risk assessments, and security checks. Government missions also typically get priority on ULA and SpaceX’s launch schedules. All of this adds up to more money.

A heavy burden

Four of the five launches awarded to SpaceX Friday will use the company’s larger Falcon Heavy rocket, according to Lt. Col. Kristina Stewart at Space Systems Command. One will fly on SpaceX’s workhorse Falcon 9. This is the first time a majority of the Space Force’s annual launch orders has required the lift capability of a Falcon Heavy, with three Falcon 9 booster cores combining to heave larger payloads into space.

All versions of ULA’s Vulcan rocket use a single core booster, with varying numbers of strap-on solid-fueled rocket motors to provide extra thrust off the launch pad.

Here’s a breakdown of the seven new missions assigned to SpaceX and ULA:

USSF-149: Classified payload on a SpaceX Falcon 9 from Florida

USSF-63: Classified payload on a SpaceX Falcon Heavy from Florida

USSF-155: Classified payload SpaceX Falcon Heavy from Florida

USSF-205: WGS-12 communications satellite on a SpaceX Falcon Heavy from Florida

NROL-86: Classified payload on a SpaceX Falcon Heavy from Florida

USSF-88: GPS IIIF-4 navigation satellite on a ULA Vulcan VC2S (two solid rocket boosters) from Florida

NROL-88: Classified payload on a ULA Vulcan VC4S (four solid rocket boosters) from Florida

Blue Origin aims to land next New Glenn booster, then reuse it for Moon mission

There’s a good bit riding on the second launch of Blue Origin’s New Glenn rocket.

Most directly, the fate of a NASA science mission to study Mars’ upper atmosphere hinges on a successful launch. The second flight of Blue Origin’s heavy-lifter will send two NASA-funded satellites toward the red planet to study the processes that drove Mars’ evolution from a warmer, wetter world to the cold, dry planet of today.

A successful launch would also nudge Blue Origin closer to winning certification from the Space Force to begin launching national security satellites.

But there’s more on the line. If Blue Origin plans to launch its first robotic Moon lander early next year—as currently envisioned—the company needs to recover the New Glenn rocket’s first stage booster. Crews will again dispatch Blue Origin’s landing platform into the Atlantic Ocean, just as they did for the first New Glenn flight in January.

The debut launch of New Glenn successfully reached orbit, a difficult feat for the inaugural flight of any rocket. But the booster fell into the Atlantic Ocean after three of the rocket’s engines failed to reignite to slow down for landing. Engineers identified seven changes to resolve the problem, focusing on what Blue Origin calls “propellant management and engine bleed control improvements.”

Relying on reuse

Pat Remias, Blue Origin’s vice president of space systems development, said Thursday that the company is confident in nailing the landing on the second flight of New Glenn. That launch, with NASA’s next set of Mars probes, is likely to occur no earlier than November from Cape Canaveral Space Force Station, Florida.

“We fully intend to recover the New Glenn first stage on this next launch,” Remias said in a presentation at the International Astronautical Congress in Sydney. “Fully intend to do it.”

Blue Origin, owned by billionaire Jeff Bezos, nicknamed the booster stage for the next flight “Never Tell Me The Odds.” It’s not quite fair to say the company’s leadership has gone all-in with their bet that the next launch will result in a successful booster landing. But the difference between a smooth touchdown and another crash landing will have a significant effect on Bezos’ Moon program.

That’s because the third New Glenn launch, penciled in for no earlier than January of next year, will reuse the same booster flown on the upcoming second flight. The payload on that launch will be Blue Origin’s first Blue Moon lander, aiming to become the largest spacecraft to reach the lunar surface. Ars has published a lengthy feature on the Blue Moon lander’s role in NASA’s effort to return astronauts to the Moon.

“We will use that first stage on the next New Glenn launch,” Remias said. “That is the intent. We’re pretty confident this time. We knew it was going to be a long shot [to land the booster] on the first launch.”

A long shot, indeed. It took SpaceX 20 launches of its Falcon 9 rocket over five years before pulling off the first landing of a booster. It was another 15 months before SpaceX launched a previously flown Falcon 9 booster for the first time.

With New Glenn, Blue’s engineers hope to drastically shorten the learning curve. Going into the second launch, the company’s managers anticipate refurbishing the first recovered New Glenn booster to launch again within 90 days. That would be a remarkable accomplishment.

Dave Limp, Blue Origin’s CEO, wrote earlier this year on social media that recovering the booster on the second New Glenn flight will “take a little bit of luck and a lot of excellent execution.”

On September 26, Blue Origin shared this photo of the second New Glenn booster on social media.

Blue Origin’s production of second stages for the New Glenn rocket has far outpaced manufacturing of booster stages. The second stage for the second flight was test-fired in April, and Blue completed a similar static-fire test for the third second stage in August. Meanwhile, according to a social media post written by Limp last week, the body of the second New Glenn booster is assembled, and installation of its seven BE-4 engines is “well underway” at the company’s rocket factory in Florida.

The lagging production of New Glenn boosters, known as GS1s (Glenn Stage 1s), is partly by design. Blue Origin’s strategy with New Glenn has been to build a small number of GS1s, each of which is more expensive and labor-intensive than SpaceX’s Falcon 9. This approach counts on routine recoveries and rapid refurbishment of boosters between missions.

However, this strategy comes with risks, as it puts the booster landings in the critical path for ramping up New Glenn’s launch rate. At one time, Blue aimed to launch eight New Glenn flights this year; it will probably end the year with two.

Laura Maginnis, Blue Origin’s vice president of New Glenn mission management, said last month that the company was building a fleet of “several boosters” and had eight upper stages in storage. That would bode well for a quick ramp-up in launch cadence next year.

However, Blue’s engineers haven’t had a chance to inspect or test a recovered New Glenn booster. Even if the next launch concludes with a successful landing, the rocket could come back to Earth with some surprises. SpaceX’s initial development of Falcon 9 and Starship was richer in hardware, with many boosters in production to decouple successful landings from forward progress.

Blue Moon

All of this means a lot is riding on an on-target landing of the New Glenn booster on the next flight. Separate from Blue Origin’s ambitions to fly many more New Glenn rockets next year, a good recovery would also mean an earlier demonstration of the company’s first lunar lander.

The lander set to launch on the third New Glenn mission is known as Blue Moon Mark 1, an unpiloted vehicle designed to robotically deliver up to 3 metric tons (about 6,600 pounds) of cargo to the lunar surface. The spacecraft will have a height of about 26 feet (8 meters), taller than the lunar lander used for NASA’s Apollo astronaut missions.

The first Blue Moon Mark 1 is funded from Blue Origin’s coffers. It is now fully assembled and will soon ship to NASA’s Johnson Space Center in Houston for vacuum chamber testing. Then, it will travel to Florida’s Space Coast for final launch preparations.

“We are building a series, not a singular lander, but multiple types and sizes and scales of landers to go to the Moon,” Remias said.

The second Mark 1 lander will carry NASA’s VIPER rover to prospect for water ice at the Moon’s south pole in late 2027. Around the same time, Blue will use a Mark 1 lander to deploy two small satellites to orbit the Moon, flying as low as a few miles above the surface to scout for resources like water, precious metals, rare Earth elements, and helium-3 that could be extracted and exploited by future explorers.

A larger lander, Blue Moon Mark 2, is in an earlier stage of development. It will be human-rated to land astronauts on the Moon for NASA’s Artemis program.

NASA’s other crew-rated lander will be derived from SpaceX’s Starship rocket. But Starship and Blue Moon Mark 2 are years away from being ready to accommodate a human crew, and both require orbital cryogenic refueling—something never before attempted in space—to transit out to the Moon.

This has led to a bit of a dilemma at NASA. China is also working on a lunar program, eyeing a crew landing on the Moon by 2030. Many experts say that, as of today, China is on pace to land astronauts on the Moon before the United States.

Of course, 12 US astronauts walked on the Moon in the Apollo program. But no one has gone back since 1972, and NASA and China are each planning to return to the Moon to stay.

One way to speed up a US landing on the Moon might be to use a modified version of Blue Origin’s Mark 1 lander, Ars reported Thursday.

If this is the path NASA takes, the stakes for the next New Glenn launch and landing will soar even higher.
