The X-37B spaceplane lands after helping pave the way for “maneuver warfare”

On this mission, military officials said the X-37B tested “space domain awareness technology experiments” that aim to improve the Space Force’s knowledge of the space environment. Defense officials consider the space domain—like land, sea, and aira contested environment that could become a battlefield in future conflicts.

The Space Force hasn’t announced plans for the next X-37B mission. Typically, the next X-37B flight has launched within a year of the prior mission’s landing. So far, all of the X-37B flights have launched from Florida, with landings at Vandenberg and at NASA’s Kennedy Space Center, where Boeing and the Space Force refurbish the spaceplanes between missions.

The aerobraking maneuvers demonstrated by the X-37B could find applications on future operational military satellites, according to Gen. Stephen Whiting, head of US Space Command.

“The X-37 is a test and experimentation platform, but that aerobraking maneuver allowed it to bridge multiple orbital regimes, and we think this is exactly the kind of maneuverability we’d like to see in future systems, which will unlock a whole new series of operational concepts,” Whiting said in December at the Space Force Association’s Spacepower Conference.

Space Command’s “astrographic” area of responsibility (AOR) starts at the top of Earth’s atmosphere and extends to the Moon and beyond.

“An irony of the space domain is that everything in our AOR is in motion, but rarely do we use maneuver as a way to gain positional advantage,” Whiting said. “We believe at US Space Command it is vital, given the threats we now see in novel orbits that are hard for us to get to, as well as the fact that the Chinese have been testing on-orbit refueling capability, that we need some kind of sustained space maneuver.”

Improvements in maneuverability would have benefits in surveilling an adversary’s satellites, as well as in defensive and offensive combat operations in orbit.

The Space Force could attain the capability for sustained maneuvers—known in some quarters as dynamic space operations—in several ways. One is to utilize in-orbit refueling that allows satellites to “maneuver without regret,” and another is to pursue more fuel-efficient means of changing orbits, such as aerobraking or solar-electric propulsion.

Then, Whiting said Space Command could transform how it operates by employing “maneuver warfare” as the Army, Navy and Air Force do. “We think we need to move toward a joint function of true maneuver advantage in space.”

When Europe needed it most, the Ariane 6 rocket finally delivered


“For this sovereignty, we must yield to the temptation of preferring SpaceX.”

Europe’s Ariane 6 rocket lifted off Thursday from French Guiana and deployed a high-resolution reconnaissance satellite into orbit for the French military, notching a success on its first operational flight.

The 184-foot-tall (56-meter) rocket lifted off from Kourou, French Guiana, at 11: 24 am EST (16: 24 UTC). Twin solid-fueled boosters and a hydrogen-fueled core stage engine powered the Ariane 6 through thick clouds on an arcing trajectory north from the spaceport on South America’s northeastern coast.

The rocket shed its strap-on boosters a little more than two minutes into the flight, then jettisoned its core stage nearly eight minutes after liftoff. The spent rocket parts fell into the Atlantic Ocean. The upper stage’s Vinci engine ignited two times to reach a nearly circular polar orbit about 500 miles (800 kilometers) above the Earth. A little more than an hour after launch, the Ariane 6 upper stage deployed CSO-3, a sharp-eyed French military spy satellite, to begin a mission providing optical surveillance imagery to French intelligence agencies and military forces.

“This is an absolute pleasure for me today to announce that Ariane 6 has successfully placed into orbit the CSO-3 satellite,” said David Cavaillolès, who took over in January as CEO of Arianespace, the Ariane 6’s commercial operator. “Today, here in Kourou, we can say that thanks to Ariane 6, Europe and France have their own autonomous access to space back, and this is great news.”

This was the second flight of Europe’s new Ariane 6 rocket, following a mostly successful debut launch last July. The first test flight of the unproven Ariane 6 carried a batch of small, relatively inexpensive satellites. An Auxiliary Propulsion Unit (APU)—essentially a miniature second engine—on the upper stage shut down in the latter portion of the inaugural Ariane 6 flight, after the rocket reached orbit and released some of its payloads. But the unit malfunctioned before a third burn of the upper stage’s main engine, preventing the Ariane 6 from targeting a controlled reentry into the atmosphere.

The APU has several jobs on an Ariane 6 flight, including maintaining pressure inside the upper stage’s cryogenic propellant tanks, settling propellants before each main engine firing, and making fine adjustments to the rocket’s position in space. The APU appeared to work as designed Thursday, although this launch flew a less demanding profile than the test flight last year.

Is Ariane 6 the solution?

Ariane 6 has been exorbitantly costly and years late, but its first operational success comes at an opportune time for Europe.

Philippe Baptiste, France’s minister for research and higher education, says Ariane 6 is “proof of our space sovereignty,” as many European officials feel they can no longer rely on the United States. Baptiste, an engineer and former head of the French space agency, mentioned “sovereignty” so many times, turning his statement into a drinking game crossed my mind.

“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. “Should I mention the uncertainties weighing today on our cooperation with NASA and NOAA, when emblematic programs like the ISS (International Space Station) are being unilaterally questioned by Elon Musk?

“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,” he continued.

Baptiste’s comments echo remarks from a range of European leaders in recent weeks.

French President Emmanuel Macron said in a televised address Wednesday night that the French were “legitimately worried” about European security after Trump reversed US policy on Ukraine. America’s NATO allies are largely united in their desire to continue supporting Ukraine in its defense against Russia’s invasion, while the Trump administration seeks a ceasefire that would require significant Ukrainian concessions.

“I want to believe that the United States will stay by our side, but we have to be prepared for that not to be the case,” Macron said. “The future of Europe does not have to be decided in Washington or Moscow.”

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.”

Merz also suggested Germany, France, and the United Kingdom should explore cooperation on a European nuclear deterrent to replace that of the United States, which has committed to protecting European territory from Russian attack for more than 75 years. Macron said the French military, which runs the only nuclear forces in Europe fully independent of the United States, could be used to protect allies elsewhere on the continent.

Access to space is also a strategic imperative for Europe, and it hasn’t come cheap. ESA paid more than $4 billion to develop the Ariane 6 rocket as a cheaper, more capable replacement for the Ariane 5, which retired in 2023. There are still pressing questions about Ariane 6’s cost per launch and whether the rocket will ever be able to meet its price target and compete with SpaceX and other companies in the commercial market.

But European officials have freely admitted the commercial market is secondary on their list of Ariane 6 goals.

European satellite operators stopped launching their payloads on Russian rockets after the invasion of Ukraine in 2022. Now, with Elon Musk inserting himself into European politics, there’s little appetite among European government officials to launch their satellites on SpaceX’s Falcon 9 rocket.

The Falcon 9 was the go-to choice for the European Space Agency, the European Union, and several national governments in Europe after they lost access to Russia’s Soyuz rocket and when Europe’s homemade Ariane 6 and Vega rockets faced lengthy delays. ESA launched a $1.5 billion space telescope on a Falcon 9 rocket in 2023, then returned to SpaceX to launch a climate research satellite and an asteroid explorer last year. The European Union paid SpaceX to launch four satellites for its flagship Galileo navigation network.

European space officials weren’t thrilled to do this. ESA was somewhat more accepting of the situation, with the agency’s director general recognizing Europe was suffering from an “acute launcher crisis” two years ago. On the other hand, the EU refused to even acknowledge SpaceX’s role in delivering Galileo satellites to orbit in the text of a post-launch press release.

“For this sovereignty, we must yield to the temptation of preferring SpaceX or another competitor that may seem trendier, more reliable, or cheaper,” Baptiste said. “We did not yield for CSO-3, and we will not yield in the future. We cannot yield because doing so would mean closing the door to space for good, and there would be no turning back. This is why the first commercial launch of Ariane 6 is not just a technical and one-off success. It marks a new milestone, essential in the choice of European space independence and sovereignty.”

Two flights into its career, Ariane 6 seems to offer a technical solution for Europe’s needs. But at what cost? Arianespace hasn’t publicly disclosed the cost for an Ariane 6 launch, although it’s likely somewhere in the range of 80 million to 100 million euros, about 40 percent lower than the cost of an Ariane 5. This is about 50 percent more than SpaceX’s list price for a dedicated Falcon 9 launch.

A new wave of European startups should soon begin launching small rockets to gain a foothold in the continent’s launch industry. These include Isar Aerospace, which could launch its first Spectrum rocket in a matter of weeks. These companies have the potential to offer Europe an option for cheaper rides to space, but the startups won’t have a rocket in the class of Ariane 6 until at least the 2030s.

Until then, at least, European governments will have to pay more to guarantee autonomous access to space.

ula’s-vulcan-rocket-still-doesn’t-have-the-space-force’s-seal-of-approval

ULA’s Vulcan rocket still doesn’t have the Space Force’s seal of approval

ULA crews at Cape Canaveral have already stacked the next Vulcan rocket on its mobile launch platform in anticipation of launching the USSF-106 mission. But with the Space Force’s Space Systems Command still withholding certification, there’s no confirmed launch date for USSF-106.

So ULA is pivoting to another customer on its launch manifest.

Amazon’s first group of production satellites for the company’s Kuiper Internet network is now first in line on ULA’s schedule. Amazon confirmed last month that it would ship Kuiper satellites to Cape Canaveral from its factory in Kirkland, Washington. Like ULA, Amazon has run into its own delays with manufacturing Kuiper satellites.

“These satellites, built to withstand the harsh conditions of space and the journey there, will be processed upon arrival to get them ready for launch,” Amazon posted on X. “These satellites will bring fast, reliable Internet to customers even in remote areas. Stay tuned for our first launch this year.”

Amazon and the Space Force take up nearly all of ULA’s launch backlog. Amazon has eight flights reserved on Atlas V rockets and 38 missions booked on the Vulcan launcher to deploy about half of its 3,232 satellites to compete with SpaceX’s Starlink network. Amazon also has launch contracts with Blue Origin, which is owned by Amazon founder Jeff Bezos, along with Arianespace and SpaceX.

The good news is that United Launch Alliance has an inventory of rockets awaiting an opportunity to fly. The company plans to finish manufacturing its remaining 15 Atlas V rockets within a few months, allowing the factory in Decatur, Alabama, to focus solely on producing Vulcan launch vehicles. ULA has all the major parts for two Vulcan rockets in storage at Cape Canaveral.

“We have a stockpile of rockets, which is kind of unusual,” Bruno said. “Normally, you build it, you fly it, you build another one… I would certainly want anyone who’s ready to go to space able to go to space.”

Space Force officials now aim to finish the certification of the Vulcan rocket in late February or early March. This would clear the path for launching the USSF-106 mission after the next Atlas V. Once the Kuiper launch gets off the ground, teams will bring the Vulcan rocket’s components back to the hangar to be stacked again.

The Space Force has not set a launch date for USSF-106, but the service says liftoff is targeted for sometime between the beginning of April and the end of June, nearly five years after ULA won its lucrative contract.

Rocket Report: Another hiccup with SpaceX upper stage; Japan’s H3 starts strong

Welcome to Edition 7.30 of the Rocket Report! The US government relies on SpaceX for a lot of missions. These include launching national security satellites, putting astronauts on the Moon, and global broadband communications. But there are hurdles—technical and, increasingly, political—on the road ahead. To put it generously, Elon Musk, without whom much of what SpaceX does wouldn’t be possible, is one of the most divisive figures in American life today.

Now, a Democratic lawmaker in Congress has introduced a bill that would end federal contracts for special government employees (like Musk), citing conflict-of-interest concerns. The bill will go nowhere with Republicans in control of Congress, but it is enough to make me pause and think. When the Trump era passes and a new administration takes the White House, how will they view Musk? Will there be an appetite to reduce the government’s reliance on SpaceX? To answer this question, you must first ask if the government will even have a choice. What if, as is the case in many areas today, there’s no viable replacement for the services offered by SpaceX?

Blue Origin flight focuses on lunar research. For the first time, Jeff Bezos’ Blue Origin space venture has put its New Shepard suborbital rocket ship through a couple of minutes’ worth of Moon-level gravity, GeekWire reports. The uncrewed mission, known as NS-29, sent 30 research payloads on a 10-minute trip from Blue Origin’s Launch Site One in West Texas. For this trip, the crew capsule was spun up to 11 revolutions per minute, as opposed to the typical half-revolution per minute. The resulting centrifugal force was equivalent to one-sixth of Earth’s gravity, which is what would be felt on the Moon.

Gee, that’s cool … The experiments aboard Blue Origin’s space capsule examined how to process lunar soil to extract resources and how to manufacture solar cells on the Moon for Blue Origin’s Blue Alchemist project. Another investigated how moondust gets electrically charged and levitated when exposed to ultraviolet light. These types of experiments in partial gravity can be done on parabolic airplane flights, but those only provide a few seconds of the right conditions to simulate the Moon’s gravity.

Orbex announces two-launch deal with D-Orbit. UK-based rocket builder Orbex announced Monday that it has signed a two-launch deal with Italian in-orbit logistics provider D-Orbit, European Spaceflight reports. The deal includes capacity aboard two launches on Orbex’s Prime rocket over the next three years. D-Orbit aggregates small payloads on rideshare missions (primarily on SpaceX rockets so far) and has an orbital transfer vehicle for ferrying satellites to different altitudes after separation from a launch vehicle. Orbex’s Prime rocket is sized for the small satellite industry, and the company aims to debut it later this year.

Thanks to fresh funding? … Orbex has provided only sparse updates on its progress toward launching the Prime rocket. What we do know is that Orbex suspended plans to develop a spaceport in Scotland to focus its resources on the Prime rocket itself. Despite little evidence of any significant accomplishments, Orbex last month secured a $25 million investment from the UK government. The timing of the launch agreement with D-Orbit begs the question of whether the UK government’s backing helped seal the deal. As Andrew Parsonson of European Spaceflight writes: “Is this a clear indication of how important strong institutional backing is for the growth of privately developed launch systems in Europe?” (submitted by EllPeaTea)

Falcon 9’s upper stage misfires again. The second stage of a SpaceX Falcon 9 rocket remained in orbit following a launch Saturday from Vandenberg Space Force Base, California. The rocket successfully deployed a new batch of Starlink Internet satellites but was supposed to reignite its engine for a braking maneuver to head for a destructive reentry over the Pacific Ocean. While airspace warning notices from the FAA showed a reentry zone over the eastern Pacific Ocean, publicly available US military tracking continued to show the upper stage in orbit this week. Sources also told Ars that SpaceX delayed two Falcon 9 launches this week by a day to allow time for engineers to evaluate the problem.

3 in 6 months … This is the third time since last July that the Falcon 9’s upper stage has encountered a problem in flight. On one occasion, the upper stage failed to reach its targeted orbit, leading to the destruction of 20 Starlink satellites. Then, an upper stage misfired during a deorbit burn after an otherwise successful launch in September, causing debris to fall outside of the pre-approved danger area. After both events, the FAA briefly grounded the Falcon 9 rocket while SpaceX conducted an investigation. This time, an FAA spokesperson said the agency won’t require an investigation. “All flight events occurred within the scope of SpaceX’s licensed activities,” the spokesperson told Ars.

Vast tests hardware for commercial space station. Vast Space has started testing a qualification model of its first commercial space station but has pushed back the launch of that station into 2026, Space News reports. In an announcement Thursday, Vast said it completed a proof test of the primary structure of a test version of its Haven-1 space station habitat at a facility in Mojave, California. During the testing, Vast pumped up the pressure inside the structure to 1.8 times its normal level and conducted a leak test. “On the first try we passed that critical test,” Max Haot, chief executive of Vast, told Space News.

Not this year … It’s encouraging to see Vast making tangible progress in developing its commercial space station. The privately held company is one of several seeking to develop a commercial outpost in low-Earth orbit to replace the International Space Station after its scheduled retirement in 2030. NASA is providing funding to two industrial teams led by Blue Origin and Voyager Space, which are working on different space station concepts. But so far, Vast’s work has been funded primarily through private capital. The launch of the Haven-1 outpost, which Vast previously said could happen this year, is now scheduled no earlier than May 2026. The spacecraft will launch in one piece on a Falcon 9 rocket, and the first astronaut crew to visit Haven-1 could launch a month later. Haven-1 is a pathfinder for a larger commercial station called Haven-2, which Vast intends to propose to NASA. (submitted by EllPeaTea)

H3 deploys Japanese navigation satellite. Japan successfully launched a flagship H3 rocket Sunday and put into orbit a Quasi-Zenith Satellite (QZS), aiming to improve the accuracy of global positioning data for various applications, Kyodo News reports. After separation from the H3 rocket, the Michibiki 6 satellite will climb into geostationary orbit, where it will supplement navigation signals from GPS satellites to provide more accurate positioning data to users in Japan and surrounding regions, particularly in mountainous terrain and amid high-rise buildings in large cities. The new satellite joins a network of four QZS spacecraft launched by Japan beginning in 2010. Two more Quasi-Zenith Satellites are under construction, and Japan’s government is expected to begin development of an additional four regional navigation satellites this year.

A good start … After a failed inaugural flight in 2023, Japan’s new H3 rocket has reeled off four consecutive successful launches in less than a year. This may not sound like a lot, but the H3 has achieved its first four successful flights faster than any other rocket since 2000. SpaceX’s Falcon 9 rocket completed its first four successful flights in a little more than two years, and United Launch Alliance’s Atlas V logged its fourth flight in a similar timeframe. More than 14 months elapsed between the first and fourth successful flight of Rocket Lab’s Electron rocket. The H3 is an expendable rocket with no roadmap to reusability, so its service life and commercial potential are likely limited. But the rocket is shaping up to provide reliable access to space for Japan’s space agency and military, while some of its peers in Europe and the United States struggle to ramp up to a steady launch cadence.

Europe really doesn’t like relying on Elon Musk. Europe’s space industry has struggled to keep up with SpaceX for a decade. The writing was on the wall when SpaceX landed a Falcon 9 booster for the first time. Now, European officials are wary of becoming too reliant on SpaceX, and there’s broad agreement on the continent that Europe should have the capability to launch its own satellites. In this way, access to space is a strategic imperative for Europe. The problem is, Europe’s new Ariane 6 rocket is just not competitive with SpaceX’s Falcon 9, and there’s no concrete plan to counter SpaceX’s dominance.

So here’s another terrible idea … Airbus, Europe’s largest aerospace contractor with a 50 percent stake in the Ariane 6 program, has enlisted Goldman Sachs for advice on how to forge a new European space and satellite company to better compete with SpaceX. France-based Thales and the Italian company Leonardo are part of the talks, with Bank of America also advising on the initiative. The idea that some bankers from Goldman and Bank of America will go into the guts of some of Europe’s largest institutional space companies and emerge with a lean, competitive entity seems far-fetched, to put it mildly, Ars reports.

The FAA still has some bite. We’re now three weeks removed from the most recent test flight of SpaceX’s Starship rocket, which ended with the failure of the vehicle’s upper stage in the final moments of its launch sequence. The accident rained debris over the Atlantic Ocean and the Turks and Caicos Islands. Unsurprisingly, the Federal Aviation Administration grounded Starship and ordered an investigation into the accident on the day after the launch. This decision came three days before the inauguration of President Donald Trump, who counts Musk as one of his top allies. So far, the FAA hasn’t budged on its requirement for an investigation, an agency spokesperson told Ars.

Debris field … In the hours and days after the failed Starship launch, residents and tourists in the Turks and Caicos shared images of debris scattered across the islands and washing up onshore. The good news is there were no injuries or reports of significant damage from the wreckage, but the FAA confirmed one report of minor damage to a vehicle located in South Caicos. It’s rare for debris from US rockets to fall over land during a launch. This would typically only happen if a launch failed at certain parts of the flight. Before now, there has been no public record of any claims of third-party property damage in the era of commercial spaceflight.

DOD eager to reap the benefits of Starship. A Defense Department unit is examining how SpaceX’s Starship vehicle could be used to support a broader architecture of in-space refueling, Space News reports. A senior adviser at the Defense Innovation Unit (DIU) said SpaceX approached the agency about how Starship’s refueling architecture could be used by the wider space industry. The plan for Starship is to transfer cryogenic propellants between tankers, depots, and ships heading to the Moon, Mars, or other deep-space destinations.

Few details available … US military officials have expressed interest in orbital refueling to support in-space mobility, where ground controllers have the freedom to maneuver national security satellites between different orbits without worrying about running out of propellant. For several years, Space Force commanders and Pentagon officials have touted the importance of in-space mobility, or dynamic space operations, in a new era of orbital warfare. However, there are reports that the Space Force has considered zeroing out a budget line item for space mobility in its upcoming fiscal year 2026 budget request.

A small step toward a fully reusable European rocket. The French space agency CNES has issued a call for proposals to develop a reusable upper stage for a heavy-lift rocket, European Spaceflight reports. This project is named DEMESURE (DEMonstration Étage SUpérieur REutilisable / Reusable Upper Stage Demonstration), and it marks one of Europe’s first steps in developing a fully reusable rocket. That’s all good, but there’s a sense of tentativeness in this announcement. The current call for proposals will only cover the earliest phases of development, such as a requirements evaluation, cost estimation review, and a feasibility meeting. A future call will deal with the design and fabrication of a “reduced scale” upper stage, followed by a demonstration phase with a test flight, recovery, and reuse of the vehicle. CNES’s vision is to field a fully reusable rocket as a successor to the single-use Ariane 6.

Toes in the water … If you’re looking for reasons to be skeptical about Project DEMESURE, look no further than the Themis program, which aims to demonstrate the recovery and reuse of a booster stage akin to SpaceX’s Falcon 9. Themis originated in a partnership between CNES and European industry in 2019, then ESA took over the project in 2020. Five years later, the Themis demonstrator still hasn’t flown. After some initial low-altitude hops, Themis is supposed to launch on a high-altitude test flight and maneuver through the entire flight profile of a reusable booster, from liftoff to a vertical propulsive landing. As we’ve seen with SpaceX, recovering an orbital-class upper stage is a lot harder than landing the booster. An optimistic view of this announcement is that anything worth doing requires taking a first step, and that’s what CNES has done here. (submitted by EllPeaTea)

Trump executive order calls for a next-generation missile defense shield

One of the new Trump administration’s first national security directives aims to defend against missile and drone attacks targeting the United States, and several elements of the plan require an expansion of the US military’s presence in space, the White House announced Monday.

For more than 60 years, the military has launched reconnaissance, communications, and missile warning satellites into orbit. Trump’s executive order calls for the Pentagon to come up with a design architecture, requirements, and an implementation plan for the next-generation missile defense shield within 60 days.

A key tenet of Trump’s order is to develop and deploy space-based interceptors capable of destroying enemy missiles during their initial boost phase shortly after launch.

“The United States will provide for the common defense of its citizens and the nation by deploying and maintaining a next-generation missile defense shield,” the order reads. “The United States will deter—and defend its citizens and critical infrastructure against—any foreign aerial attack on the homeland.”

The White House described the missile defense shield as an “Iron Dome for America,” referring to the name of Israel’s regional missile defense system. While Israel’s Iron Dome is tailored for short-range missiles, the White House said the US version will guard against all kinds of airborne attacks.

What does the order actually say?

Trump’s order is prescriptive in what to do, but it leaves the implementation up to the Pentagon. The White House said the military’s plan must defend against many types of aerial threats, including ballistic, hypersonic, and advanced cruise missiles, plus “other next-generation aerial attacks,” a category that appears to include drones and shorter-range unguided missiles.

Rocket Report: China launches refueling demo; DoD’s big appetite for hypersonics


We’re just a few days away from getting a double-dose of heavy-lift rocket action.

Welcome to Edition 7.26 of the Rocket Report! Let’s pause and reflect on how far the rocket business has come in the last 10 years. On this date in 2015, SpaceX made the first attempt to land a Falcon 9 booster on a drone ship positioned in the Atlantic Ocean. Not surprisingly, the rocket crash-landed. In less than a year and a half, though, SpaceX successfully landed reusable Falcon 9 boosters onshore and offshore, and now has done it nearly 400 times. That was remarkable enough, but we’re in a new era now. Within a few days, we could see SpaceX catch its second Super Heavy booster and Blue Origin land its first New Glenn rocket on an offshore platform. Extraordinary.

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.

Our annual ranking of the top 10 US launch companies. You can easily guess who made the top of the list: the company that launched Falcon rockets 134 times in 2024 and launched the most powerful and largest rocket ever built on four test flights, each accomplishing more than the last. The combined 138 launches is more than NASA flew the Space Shuttle over three decades. SpaceX will aim to launch even more often in 2025. These missions have far-reaching impacts, supporting Internet coverage for consumers worldwide, launching payloads for NASA and the US military, and testing technology that will take humans back to the Moon and, someday, Mars.

Are there really 10? … It might also be fairly easy to rattle off a few more launch companies that accomplished big things in 2024. There’s United Launch Alliance, which finally debuted its long-delayed Vulcan rocket and flew two Atlas V missions and the final Delta IV mission, and Rocket Lab, which launched 16 missions with its small Electron rocket this year. Blue Origin flew its suborbital New Shepard vehicle on three human missions and one cargo-only mission and nearly launched its first orbital-class New Glenn rocket in 2024. That leaves just Firefly Aerospace as the only other US company to reach orbit last year.

DoD announces lucrative hypersonics deal. Defense technology firm Kratos has inked a deal worth up to $1.45 billion with the Pentagon to help develop a low-cost testbed for hypersonic technologies, Breaking Defense reports. The award is part of the military’s Multi-Service Advanced Capability Hypersonic Test Bed (MACH-TB) 2.0 program. The MACH-TB program, which began as a US Navy effort, includes multiple “Task Areas.” For its part, Kratos will be tasked with “systems engineering, integration, and testing, to include integrated subscale, full-scale, and air launch services to address the need to affordably increase hypersonic flight test cadence,” according to the company’s release.

Multiple players … The team led by Kratos, which specializes in developing airborne drones and military weapons systems, includes several players such as Leidos, Rocket Lab, Stratolaunch, and others. Kratos last year revealed that its Erinyes hypersonic test vehicle successfully flew for a Missile Defense Agency experiment. Rocket Lab has launched multiple suborbital hypersonic experiments for the military using a modified version of its Electron rocket, and Stratolaunch reportedly flew a high-speed test vehicle and recovered it last month, according to Aviation Week & Space Technology.

ESA will modify some of its geo-return policies. An upcoming European launch competition will be an early test of efforts by the European Space Agency to modify its approach to policies that link contracts to member state contributions, Space News reports. ESA has long used a policy known as geo-return, where member states are guaranteed contracts with companies based in their countries in proportion to the contribution those member states make to ESA programs.

The third rail of European space … Advocates of geo-return argue that it provides an incentive for countries to fund those programs. This incentivizes ESA to lure financial contributions from its member states, which will win guaranteed business and jobs from the agency’s programs. However, critics of geo-return, primarily European companies, claim that it creates inefficiencies that make them less competitive. One approach to revising geo-return is known as “fair contribution,” where ESA first holds competitions for projects, and member states then make contributions based on how companies in their countries fared in the competition. ESA will try the fair contribution approach for the upcoming launch competition to award contracts to European rocket startups. (submitted by EllPeaTea)

RFA is building a new rocket. German launch services provider Rocket Factory Augsburg (RFA) is currently focused on building a new first stage for the inaugural flight of its RFA One rocket, European Spaceflight reports. The stage that was initially earmarked for the flight was destroyed during a static fire test last year on a launch pad in Scotland. In a statement given to European Spaceflight, RFA confirmed that it expects to attempt an inaugural flight of RFA One in 2025.

Waiting on a booster … RFA says it is “fully focused on building a new first stage and qualifying it.” The rocket’s second stage and Redshift OTV third stage are already qualified for flight and are being stored until a new first stage is ready. The RFA One rocket will stand 98 feet (30 meters) tall and will be capable of delivering payloads of up to 1.3 metric tons (nearly 2,900 pounds) into polar orbits. RFA is one of several European startups developing commercial small satellite launchers and was widely considered the frontrunner before last year’s setback. (submitted by EllPeaTea)

Pentagon provides a boost for defense startup. Defense technology contractor Anduril Industries has secured a $14.3 million Pentagon contract to expand solid-fueled rocket motor production, as the US Department of Defense moves to strengthen domestic manufacturing capabilities amid growing supply chain concerns, Space News reports. The contract, awarded under the Defense Production Act, will support facility modernization and manufacturing improvements at Anduril’s Mississippi plant, the Pentagon said Tuesday.

Doing a solid … The Pentagon is keen to incentivize new entrants into the solid rocket manufacturing industry, which provides propulsion for missiles, interceptors, and other weapons systems. Two traditional defense contractors, Northrop Grumman and L3Harris, control almost all US solid rocket production. Companies like Anduril, Ursa Major, and X-Bow are developing solid rocket motor production capability. The Navy previously awarded Anduril a $19 million contract last year to develop solid rocket motors for the Standard Missile 6 program. (submitted by EllPeaTea)

Relativity’s value seems to be plummeting. For several years, an innovative, California-based launch company named Relativity Space has been the darling of investors and media. But the honeymoon appears to be over, Ars reports. A little more than a year ago, Relativity reached a valuation of $4.5 billion following its latest Series F fundraising round. This was despite only launching one rocket and then abandoning that program and pivoting to the development of a significantly larger reusable launch vehicle. The decision meant Relativity would not realize any significant revenue for several years, and Ars reported in September on some of the challenges the company has encountered developing the much larger Terran R rocket.

Gravity always wins … Relativity is a privately held company, so its financial statements aren’t public. However, we can glean some clues from the published quarterly report from Fidelity Investments, which owns Relativity shares. As of March 2024, Fidelity valued its 1.67 million shares at an estimated $31.8 million. However, in a report ending November 29 of last year, which was only recently published, Fidelity’s valuation of Relativity plummeted. Its stake in Relativity was then thought to be worth just $866,735—a per-share value of 52 cents. Shares in the other fundraising rounds are also valued at less than $1 each.

SpaceX has already launched four times this year. The space company is off to a fast start in 2025, with four missions in the first nine days of the year. Two of these missions launched Starlink internet satellites, and the other two deployed an Emirati-owned geostationary communications satellite and a batch of Starshield surveillance satellites for the National Reconnaissance Office. In its new year projections, SpaceX estimates it will launch more than 170 Falcon rockets, between Falcon 9 and Falcon Heavy, Spaceflight Now reports. This is in addition to SpaceX’s plans for up to 25 flights of the Starship rocket from Texas.

What’s in store this year?… Highlights of SpaceX’s launch manifest this year will likely include an attempt to catch and recover Starship after returning from orbit, a first in-orbit cryogenic propellant transfer demonstration with Starship, and perhaps the debut of a second launch pad at Starbase in South Texas. For the Falcon rocket fleet, notable missions this year will include launches of commercial robotic lunar landers for NASA’s CLPS program and several crew flights, including the first human spaceflight mission to fly in polar orbit. According to public schedules, a Falcon 9 rocket could launch a commercial mini-space station for Vast, a privately held startup, before the end of the year. That would be a significant accomplishment, but we won’t be surprised if this schedule moves to the right.

China is dipping its toes into satellite refueling. China kicked off its 2025 launch activities with the successful launch of the Shijian-25 satellite Monday, aiming to advance key technologies for on-orbit refueling and extending satellite lifespans, Space News reports. The satellite launched on a Long March 3B into a geostationary transfer orbit, suggesting the unspecified target spacecraft for the refueling demo test might be in geostationary orbit more than 22,000 miles (nearly 36,000 kilometers) over the equator.

Under a watchful eye … China has tested mission extension and satellite servicing capabilities in space before. In 2021, China launched a satellite named Shijian-21, which docked a defunct Beidou navigation satellite and towed it to a graveyard orbit above the geostationary belt. Reportedly, Shijian-21 satellite may have carried robotic arms to capture and manipulate other objects in space. These kinds of technologies are dual-use, meaning they have civilian and military applications. The US Space Force is also interested in satellite life extension and refueling tech, so US officials will closely monitor Shijian-25’s actions in orbit.

SpaceX set to debut upgraded Starship. An upsized version of SpaceX’s Starship mega-rocket rolled to the launch pad early Thursday in preparation for liftoff on a test flight next week, Ars reports. The rocket could lift off as soon as Monday from SpaceX’s Starbase test facility in South Texas. This flight is the seventh full-scale demonstration launch for Starship. The rocket will test numerous upgrades, including a new flap design, larger propellant tanks, redesigned propellant feed lines, a new avionics system, and an improved antenna for communications and navigation.

The new largest rocket … Put together, all of these changes to the ship raise the rocket’s total height by nearly 6 feet (1.8 meters), so it now towers 404 feet (123.1 meters) tall. With this change, SpaceX will break its own record for the largest rocket ever launched. SpaceX plans to catch the rocket’s Super Heavy booster back at the launch site in Texas and will target a controlled splashdown of the ship in the Indian Ocean.

Blue Origin targets weekend launch of New Glenn. Blue Origin is set to launch its New Glenn rocket in a long-delayed, uncrewed test mission that would help pave the way for the space venture founded by Jeff Bezos to compete against Elon Musk’s SpaceX, The Washington Post reports. Blue Origin has confirmed it plans to launch the 320-foot-tall rocket during a three-hour launch window opening at 1 am EDT (06: 00 UTC) Sunday in the company’s first attempt to reach orbit.

Finally … This is a much-anticipated milestone for Blue Origin and for the company’s likely customers, which include the Pentagon and NASA. Data from this test flight will help the Space Force certify New Glenn to loft national security satellites, providing a new competitor for SpaceX and United Launch Alliance in the heavy-lift segment of the market. Blue Origin isn’t quite shooting for the Moon on this inaugural launch, but the company will attempt to reach orbit and try to land the New Glenn’s first stage booster on a barge in the Atlantic Ocean.

the-us-military-is-now-talking-openly-about-going-on-the-attack-in-space

The US military is now talking openly about going on the attack in space

Mastalir said China is “copying the US playbook” with the way it integrates satellites into more conventional military operations on land, in the air, and at sea. “Their specific goals are to be able to track and target US high-value assets at the time and place of their choosing,” Mastalir said.

China’s strategy, known as Anti-Access/Area Denial, or A2AD, is centered on preventing US forces from accessing international waters extending hundreds or thousands of miles from mainland China. Some of the islands occupied by China within the last 15 years are closer to the Philippines, another treaty ally, than to China itself.

The A2AD strategy first “extended to the first island chain (bounded by the Philippines), and now the second island chain (extending to the US territory of Guam), and eventually all the way to the West Coast of California,” Mastalir said.

US officials say China has based anti-ship, anti-air, and anti-ballistic weapons in the region, and many of these systems rely on satellite tracking and targeting. Mastalir said his priority at Indo-Pacific Command, headquartered in Hawaii, is to defend US and allied satellites, or “blue assets,” and challenge “red assets” to break the Chinese military’s “long-range kill chains and protect the joint force from space-enabled attack.”

What this means is the Space Force wants to have the ability to disable or destroy the satellites China would use to provide communication, command, tracking, navigation, or surveillance support during an attack against the US or its allies.

Mastalir said he believes China’s space-based capabilities are “sufficient” to achieve the country’s military ambitions, whatever they are. “The sophistication of their sensors is certainly continuing to increase—the interconnectedness, the interoperability. They’re a pacing challenge for a reason,” he said.

“We’re seeing all signs point to being able to target US aircraft carriers… high-value assets in the air like tankers, AWACS (Airborne Warning And Control System),” Mastalir said. “This is a strategy to keep the US from intervening, and that’s what their space architecture is.”

That’s not acceptable to Pentagon officials, so Space Force personnel are now training for orbital warfare. Just don’t expect to know the specifics of any of these weapons systems any time soon.

“The details of that? No, you’re not going to get that from any war-fighting organization—’let me tell you precisely how I intend to attack an adversary so that they can respond and counter that’—those aren’t discussions we’re going to have,” Saltzman said. “We’re still going to protect some of those (details), but broadly, from an operational concept, we are going to be ready to contest space.”

A new administration

The Space Force will likely receive new policy directives after President-elect Donald Trump takes office in January. The Trump transition team hasn’t identified any changes coming for the Space Force, but a list of policy proposals known as Project 2025 may offer some clues.

Published by the Heritage Foundation, a conservative think tank, Project 2025 calls for the Pentagon to pivot the Space Force from a mostly defensive posture toward offensive weapons systems. Christopher Miller, who served as acting secretary of defense in the first Trump administration, authored the military section of Project 2025.

Miller wrote that the Space Force should “reestablish offensive capabilities to guarantee a favorable balance of forces, efficiently manage the full deterrence spectrum, and seriously complicate enemy calculations of a successful first strike against US space assets.”

Trump disavowed Project 2025 during the campaign, but since the election, he has nominated several of the policy agenda’s authors and contributors to key administration posts.

Saltzman met with Trump last month while attending a launch of SpaceX’s Starship rocket in Texas, but he said the encounter was incidental. Saltzman was already there for discussions with SpaceX officials, and Trump’s travel plans only became known the day before the launch.

The conversation with Trump at the Starship launch didn’t touch on any policy details, according to Saltzman. He added that the Space Force hasn’t yet had any formal discussions with the Trump transition team.

Regardless of the direction Trump takes with the Space Force, Saltzman said the service is already thinking about what to do to maintain what the Pentagon now calls “space superiority”—a twist on the term air superiority, which might have seemed equally as fanciful at the dawn of military aviation more than a century ago.

“That’s the reason we’re the Space Force,” Saltzman said. “So administration to administration, that’s still going to be true. Now, it’s just about resourcing and the discussions about what we want to do and when we want to do it, and we’re ready to have those discussions.”

a-lot-of-people-are-mistaking-elon-musk’s-starlink-satellites-for-uaps

A lot of people are mistaking Elon Musk’s Starlink satellites for UAPs

That’s just Elon

But many UAP cases have verifiable explanations as airplanes, drones, or satellites, and lawmakers argue AARO might be able to solve more of the cases with more funding.

Airspace is busier than ever with air travel and consumer drones. More satellites are zooming around the planet as government agencies and companies like SpaceX deploy their constellations for Internet connectivity and surveillance. There’s more stuff up there to see.

“AARO increasingly receives cases that it is able to resolve to the Starlink satellite constellation,” the office said in this year’s annual report.

“For example, a commercial pilot reported white flashing lights in the night sky,” AARO said. “The pilot did not report an altitude or speed, and no data or imagery was recorded. AARO assessed that this sighting of flashing lights correlated with a Starlink satellite launch from Cape Canaveral, Florida, the same evening about one hour prior to the sighting.”

Jon Kosloski, director of AARO, said officials compared the parameters of these sightings with Starlink launches. When SpaceX releases Starlink satellites in orbit, the spacecraft are initially clustered together and reflect more sunlight down to Earth. This makes the satellites easier to see during twilight hours before they raise their orbits and become dimmer.

“We found some of those correlations in time, the direction that they were looking, and the location,” Kosloski said. “And we were able to assess that they were all in those cases looking at Starlink flares.”

SpaceX has more than 6,600 Starlink satellites in low-Earth orbit, more than half of all active spacecraft. Thousands more satellites for Amazon’s Kuiper broadband constellation and Chinese Internet network are slated to launch in the next few years.

“AARO is investigating if other unresolved cases may be attributed to the expansion of the Starlink and other mega-constellations in low-Earth orbit,” the report said.

The Starlink network is still relatively new. SpaceX launched the first Starlinks five years ago. Kosloski said he expects the number of erroneous UAP reports caused by satellites to go down as pilots and others understand what the Starlinks look like.

“It looks interesting and potentially anomalous. But we can model that, and we can show pilots what that anomaly looks like, so that that doesn’t get reported to us necessarily,” Kosloski said.

NRO chief: “You can’t hide” from our new swarm of SpaceX-built spy satellites

The director of the National Reconnaissance Office has a message for US adversaries around the world.

“You can’t hide, because we’re constantly looking,” said Chris Scolese, a longtime NASA engineer who took the helm of the US government’s spy satellite agency in 2019.

The NRO is taking advantage of SpaceX’s Starlink satellite assembly line to build a network of at least 100 satellites, and perhaps many more, to monitor adversaries around the world. So far, more than 80 of these SpaceX-made spacecraft, each a little less than a ton in mass, have launched on four Falcon 9 rockets. There are more to come.

A large number of these mass-produced satellites, or what the NRO calls a “proliferated architecture,” will provide regularly updated imagery of foreign military installations and other sites of interest to US intelligence agencies. Scolese said the new swarm of satellites will “get us reasonably high-resolution imagery of the Earth, at a high rate of speed.”

This is a significant change in approach for the NRO, which has historically operated a smaller number of more expensive satellites, some as big as a school bus.

“We expect to quadruple the number of satellites we have to have on-orbit in the next decade,” said Col. Eric Zarybnisky, director of the NRO’s office of space launch, during an October 29 presentation at the Wernher von Braun Space Exploration Symposium in Huntsville, Alabama.

The NRO is not the only national security agency eyeing a constellation of satellites in low-Earth orbit. The Pentagon’s Space Development Agency plans to kick off a rapid-fire launch cadence next year to begin placing hundreds of small satellites in orbit to detect and track missiles threatening US or allied forces. The Space Force is also interested in buying its own set of SpaceX satellites for broadband connectivity.

The Pentagon started moving in this direction about a decade ago, when leaders raised concerns that the legacy fleets of military and spy satellites were at risk of attack. Now, Elon Musk’s SpaceX and a handful of other companies, many of them startups, specialize in manufacturing and launching small satellites at relatively low cost.

“Why didn’t we do this earlier? Well, launch costs were high, right?” said Troy Meink, the NRO’s principal deputy director, in an October 17 discussion hosted by the Mitchell Institute for Aerospace Studies. “The cost of entry was pretty high, which has come way down. Then, digital electronics has allowed us to build capability in a much smaller package, and a combination of those two is really what’s enabled it.”

A constant vigil

NRO officials still expect to require some large satellites with sharp-eyed optics—think of a Hubble Space Telescope pointed at Earth—to resolve the finest details of things like missile installations, naval fleets, or insurgent encampments. The drawback of this approach is that, at best, a few big optical or radar imaging satellites only fly over places of interest several times per day.

With the proliferated architecture, the NRO will capture views of most places on Earth a lot more often. Two of the most important metrics with a remote-sensing satellite system are imaging resolution and revisit time, or how often a satellite is over a specific location on Earth.

“We need to have persistence or fast revisit,” Scolese said on October 3 in a discussion at the Center for Strategic and International Studies, a nonprofit Washington think tank. “You can proliferate your architecture, put more satellites up there, so that a satellite is always coming over an area within a given reasonable amount of time that’s needed by the users. That’s what we’re doing with the proliferated architecture.

“That’s enabled by a really rich commercial industry that’s building hundreds or thousands of satellites,” Scolese said. “That allowed us to take those satellites, adapt them to our use at low cost, and apply whatever sensor is needed to go off and acquire the information that’s needed at whatever revisit time is required.”

The NRO has identified other benefits, too. It’s a lot more difficult for a country like Russia or China to take out an entire constellation of satellites than to destroy or disable a single spy platform in orbit. Military officials have often referred to these expensive one-off satellites as “big juicy targets” for potential adversaries.

“It gives us a degree of resilience that we didn’t have before,” Scolese said.

The proliferated constellation also allows the NRO to be more nimble in responding to threats or new technologies. If a new type of sensor becomes available, or an adversary does something new that intelligence analysts want to look at, the NRO and its contractor can quickly swap out payloads on satellites going through the production line.

“That’s a huge change for an organization like the NRO,” Zarybnisky said. “It’s a catalyst. Another catalyst for innovation in the NRO is these smaller, lower price-point systems. Rapid turn time means you can introduce that next technology into the next generation and not wait for many years or even decades to introduce new technologies.”

Three-letter agencies

The NRO provides imaging, signals, and electronic intelligence data from its satellites to the National Security Agency, the National Geospatial-Intelligence Agency, and the Department of Defense. Scolese said the NRO wants to get actionable information into the hands of users across the federal government as quickly as possible, but the volume of data coming down from hundreds of satellites presents a challenge.

“Once you go to a proliferated architecture and you’re going from a few satellites to tens of satellites to now hundreds of satellites, you have to change a lot of things, and we’re in the process of doing that,” Scolese said.

With so many satellites, it “means that it’s no longer possible for an individual sitting at a control center to say, ‘I know what this satellite is doing,'” Scolese said. “So we have to have the machines to go off and help us there. We need artificial intelligence, machine learning, automated processes to help us do that.”

“We will deliver data in seconds, not minutes, and not hours,” Zarybnisky said.

The existence of this constellation was made public in March, when Reuters reported the NRO was working with SpaceX to develop and deploy a network of satellites in low-Earth orbit. SpaceX’s Starshield business unit is building the satellites under a $1.8 billion contract signed in 2021, according to Reuters. This is remarkably inexpensive by the standards of the NRO, which has spent more money just constructing a satellite processing facility at Cape Canaveral, Florida (thanks to Eric Berger’s reporting in Reentry for this juicy tidbit).

Reuters reported Northrop Grumman is supplying sensors to mount on at least some of the SpaceX-built satellites, but their design and capabilities remain classified. The NRO, which usually keeps its work secret, officially acknowledged the program in April, a month before the first batch of satellites launched from Vandenberg Space Force Base, California.

SpaceX revealed the existence of the Starshield division in 2022, the year after signing the NRO contract, as a vehicle for applying the company’s experience manufacturing Starlink Internet satellites to support US national security missions. SpaceX has built and launched more than 7,200 Starlink satellites since 2019, with more than 6,000 currently operational, 10 times larger than any other existing satellite constellation.

The current generation of Starlink satellites launch in batches of 20 to 23 spacecraft on SpaceX’s Falcon 9 rocket. They’re flat-packed one on top of the other inside the Falcon 9’s payload shroud, then released all at once in orbit. The NRO’s new satellites likely use the same basic design, launching in groups of roughly 21 satellites on each mission.

According to Scolese, the NRO owns these SpaceX-built satellites, rather than SpaceX owning them and supplying data to the government through a service contract arrangement. By the end of the year, the NRO’s director anticipates having at least 100 of these satellites in orbit, with additional launches expected through 2028.

“We are going from the demo phase to the operational phase, where we’re really going to be able to start testing all of this stuff out in a more operational way,” Scolese said.

The NRO is buttressing its network of government-owned satellites with data buys from commercial remote-sensing companies, such as Maxar, Planet, and BlackSky. One advantage of commercial imagery is the NRO can share it widely with allies and the public because it isn’t subject to top-secret classification restrictions.

Scolese said it’s important to maintain a diversity of sources and observation methods to overcome efforts from other nations to hide what they’re doing. This means using more satellites, as the NRO is doing with SpaceX and other commercial partners. It also means using electro-optical, radar, thermal infrared, and electronic detection sensors to fully characterize what intelligence analysts are seeing.

The NRO is also studying more exotic methods like quantum remote sensing, using the principles of quantum physics at the atomic level.

“There’s camouflage,” Scolese said. “There are lots of techniques that can be used, which means we have to go off and look at very different phenomenologies, and we’ve developed and are developing capabilities that will allow us to defeat those types of activities. Quantum sensing is one of them. You can’t really hide from fundamental physics.”

as-north-korean-troops-march-toward-ukraine,-does-a-russian-quid-pro-quo-reach-space?

As North Korean troops march toward Ukraine, does a Russian quid pro quo reach space?

Earlier this week, North Korea apparently completed a successful test of its most powerful intercontinental ballistic missile, lofting it nearly 4,800 miles into space before the projectile fell back to Earth.

This solid-fueled, multi-stage missile, named the Hwasong-19, is a new tool in North Korea’s increasingly sophisticated arsenal of weapons. It has enough range—perhaps as much as 9,320 miles (15,000 kilometers), according to Japan’s government—to strike targets anywhere in the United States.

The test flight of the Hwasong-19 on Thursday was North Korea’s first test of a long-range missile in nearly a year, coming as North Korea deploys some 10,000 troops inside Russia just days before the US presidential election. US officials condemned the missile launch as a “provocative and destabilizing” action in violation of UN Security Council resolutions.

The budding partnership between Russia and North Korea has evolved for several years. Russian President Vladimir Putin has met with North Korean leader Kim Jong Un on multiple occasions, most recently in Pyongyang in June. Last September, the North Korean dictator visited Putin at the Vostochny Cosmodrome, Russia’s newest launch base, where the leaders inspected hardware for Russia’s Angara rocket.

The visit to Vostochny fueled speculation that Russia might provide missile and space technology to North Korea in exchange for Kim’s assistance in the fight against Ukraine. This week, South Korea’s defense minister said his government has identified several areas where North Korea likely seeks help from Russia.

“In exchange for their deployment, North Korea is very likely to ask for technology transfers in diverse areas, including the technologies relating to tactical nuclear weapons technologies related to their advancement of ICBMs, also those regarding reconnaissance satellites and those regarding SSBNs [ballistic missile submarines] as well,” said Kim Yong-hyun, South Korea’s top military official, on a visit to Washington.

SpaceX prevails over ULA, wins military launch contracts worth $733 million

These missions require medium-lift rockets, or smaller rockets capable of a high-rate launch cadence to match the capability of a larger launch vehicle. In June, the Space Force selected SpaceX, ULA, and Blue Origin, Jeff Bezos’s space company, to compete for Lane 1 launch task orders.

Military officials will add more companies to the pool of available Lane 1 launch providers as they mature their rockets. These companies may include Rocket Lab, Firefly Aerospace, Relativity Space, Stoke Space, and others.

While Blue Origin is on the Space Force’s list of available launch providers, the company’s New Glenn rocket was not eligible for the contracts announced Friday. That’s because military officials require a rocket to complete at least one successful orbital launch to become qualified for a Lane 1 task order. New Glenn’s first test flight is scheduled some time later this year.

This rule left SpaceX’s Falcon 9 and ULA’s Vulcan rockets as the only launch vehicles eligible for the task orders, setting up a head-to-head competition between the rival rocket companies. SpaceX prevailed, winning all nine Lane 1 missions up for competition this year.

Lane 2 of the Space Force’s National Security Space Launch program covers more challenging military missions, typically larger, more expensive payloads destined for higher orbits. The Space Force is expected to soon select launch providers for Lane 2 missions. These launches will require the Space Force to certify the rockets, whereas the military is comfortable accepting a little more risk for the Lane 1 missions.

SpaceX’s Falcon 9 and Falcon Heavy are currently certified for national security launches, and the Space Force is in the process of certifying ULA’s Vulcan launcher after two successful test flights. The Space Force and Blue Origin also have a certification plan for the New Glenn rocket, but it must first complete multiple successful test flights.

Updated October 19 with additional information about the launch task orders.

in-a-rare-disclosure,-the-pentagon-provides-an-update-on-the-x-37b-spaceplane

In a rare disclosure, the Pentagon provides an update on the X-37B spaceplane

“When it’s close to the Earth, it’s close enough to the atmosphere to turn where it is,” she said. “Which means our adversaries don’t know—and that happens on the far side of the Earth from our adversaries—where it’s going to come up next. And we know that that drives them nuts. And I’m really glad about that.”

Breaking the silence

The Pentagon rarely releases an update on the X-37B spaceplane in the middle of a mission. During previous flights, military officials typically provided some basic information about the mission before its launch, then went silent until the X-37B returned for landing. The military keeps specifics about the spaceplane’s activities in orbit a secret.

This made the Space Force’s announcement Thursday somewhat of a surprise. When the seventh flight of the X-37B launched, there were indications that the spacecraft would soar into a much higher orbit than it did on any of its six prior missions.

In February, a sleuthing satellite tracking hobbyist spotted the X-37B in orbit by observing sunlight reflected off of the spacecraft as it flew thousands of miles above Earth. Follow-up detections confirmed the discovery, allowing amateur observers to estimate that the X-37B was flying in a highly elliptical orbit ranging between roughly 300 and 38,600 miles in altitude (186-by-23,985 miles). The orbit was inclined 59.1 degrees to the equator.

On its previous missions, the X-37B was confined to low-Earth orbit a few hundred miles above the planet. When it became apparent that the latest mission was cruising at a significantly higher altitude, analysts and space enthusiasts speculated on what the secret spaceplane was doing and how it would come back to Earth. A direct reentry into the atmosphere from the spaceplane’s elliptical orbit would expose the craft’s heat shield to hotter temperatures than any of its previous returns.

Now, we have an answer to the latter question.

As for what it’s doing up there, the Space Force said the spaceplane on this mission has “conducted radiation effect experiments and has been testing space domain awareness technologies in a highly elliptical orbit.” The orbit brings the X-37B through the Van Allen radiation belts and crosses several orbital regimes populated by US and foreign communications, navigation, and surveillance satellites.

Military officials have said previous X-37B flights have tested a Hall-effect ion thruster and tested other experimental space technologies without elaborating on their details. X-37Bs have also secretly deployed small military satellites in orbit.

In a rare disclosure, the Pentagon provides an update on the X-37B spaceplane Read More »
