United Launch Alliance is free to compete for NASA contracts with its new Vulcan rocket after a successful test flight earlier this year, ending a period where SpaceX was the only company competing for rights to launch the agency’s large science missions.

For several years, ULA was unable to bid for NASA launch contracts after the company sold all of its remaining Atlas V rockets to other customers, primarily for Amazon’s Project Kuiper Internet network. ULA could not submit its new Vulcan rocket, which will replace the Atlas V, for NASA to consider in future launch contracts until the Vulcan completed at least one successful flight, according to Tim Dunn, senior launch director at NASA’s Launch Services Program.

The Vulcan rocket’s first certification flight on January 8, called Cert-1, was nearly flawless, demonstrating the launcher’s methane-fueled BE-4 engines built by Blue Origin and an uprated twin-engine Centaur upper stage. A second test flight, known as Cert-2, is scheduled to lift off no earlier than October 4 from Cape Canaveral Space Force Station, Florida. Assuming the upcoming launch is as successful as the first one, the US Space Force aims to launch its first mission on a Vulcan rocket by the end of the year.

The Space Force has already booked 25 launches on ULA’s Vulcan rocket for military payloads and spy satellites for the National Reconnaissance Office. But these missions won’t launch until Vulcan completes its second test flight, clearing the way for the Space Force to certify ULA’s new rocket for national security missions.

Back in the game

NASA’s Launch Services Program (LSP) is responsible for selecting and overseeing launch providers for the agency’s robotic science missions. NASA’s near-term options for launching large missions include SpaceX’s Falcon 9 and Falcon Heavy rockets, ULA’s Vulcan, and Blue Origin’s New Glenn launcher.

However, only SpaceX’s rockets have been available for NASA bids since 2021, when ULA sold all of its remaining Atlas V rockets to Amazon. For example, ULA did not submit proposals for the launch of a GOES weather satellite or NASA’s Roman Space Telescope, two of the more lucrative launch contracts the agency has awarded in the last couple of years. NASA selected SpaceX’s Falcon Heavy, the only eligible rocket, for both missions.

This is a notable role reversal for SpaceX and ULA, a 50-50 joint venture between Boeing and Lockheed Martin that was the sole launch provider for large NASA science missions and military satellites for nearly a decade. SpaceX launched its first mission for NASA’s Launch Services Program in January 2016.

The situation changed with the first flight of the Vulcan rocket in January.

“They certainly demonstrated a huge success earlier this year flying Cert-1,” Dunn told Ars in an interview. “They needed a successful flight to then bid for future missions, so that allowed them to be in a position to bid on our missions.”

NASA has not yet formally certified the Vulcan rocket to launch one of the agency’s science missions, but that would not stop NASA from selecting Vulcan for a contract. Some of NASA’s next big science missions up for launch contract awards include the nuclear-powered Dragonfly mission to explore Saturn’s moon Titan and an asteroid-hunting telescope named NEO Surveyor.

The second Vulcan flight next month will move ULA’s rocket toward certification by the Space Force and NASA.

“A second Cert flight that will then demonstrate a few other capabilities of the rocket allows more data for our certification team that is working in concert with the US Space Force’s certification team,” Dunn said. “We’re doing a lot of shared, intergovernmental collaborations in the certification work, so it allows us all more data, more confidence in that launch vehicle to meet all the needs that we believe we will have in the coming decade-plus.”

Blue Origin’s New Glenn could also compete for contracts to launch NASA’s larger, more expensive missions after it completes at least one successful flight. Blue Origin is currently eligible for bids to launch NASA’s smaller missions, such as the ESCAPADE mission to Mars already assigned to New Glenn. NASA is willing to accept more risk for launching these types of lower-cost missions.

ULA capped off the assembly of its second Vulcan rocket at Cape Canaveral on Saturday when technicians lifted the launcher’s payload fairing atop Vulcan’s first-stage booster and Centaur upper stage. For its second launch, Vulcan will carry a dummy payload instead of a real satellite. The second Vulcan flight was initially supposed to launch Sierra Space’s first Dream Chaser spaceplane to the International Space Station, but Dream Chaser isn’t ready, and the Space Force is eager for ULA to get moving and finish the certification process.

The head of Space Systems Command, Lt. Gen. Philip Garrant, told Ars last week that he is “optimistic” ULA will be in a position to launch its first Space Force missions with the Vulcan rocket by the end of this year. ULA has already delivered Vulcan rocket parts for the next two missions to Cape Canaveral, but the Cert-2 launch needs to go off without a hitch.

“We’re working very closely with ULA on that, as well as the manifest for the following missions,” Garrant said. “All of the rocket parts are at the launch locations, ready to go, but clearly the priority is the certification flight and making sure that the launch vehicle is certified. But we are optimistic that we’re going to get those launches off.”

Space Command chief says dialogue with China is too often a one-way street

The head of US Space Command said Wednesday he would like to see more transparency from the Chinese government on space debris, especially as one of China’s newer rockets has shown a propensity for breaking apart and littering low-Earth orbit with hundreds of pieces of space junk.

Gen. Stephen Whiting, commander of US Space Command, said he’s observed some improvement in the dialogue between US and Chinese military officials this year. But the disintegration of the upper stage from a Long March 6A rocket earlier this month showed China could do more to prevent the creation of space debris, and communicate openly about it when it happens.

The Chinese government acknowledged the breakup of the Long March 6A rocket’s upper stage in a statement by its Ministry of Foreign Affairs on August 14, more than a week after the rocket’s launch August 6 with the first batch of 18 Internet satellites for a megaconstellation of thousands of spacecraft analogous to SpaceX’s Starlink network.

Space Command reported it detected more than 300 objects associated with the breakup of the upper stage in orbit, and LeoLabs, a commercial space situational awareness company, said its radars detected at least 700 objects attributed to the Chinese rocket.

“I hope the next time there’s a rocket like that, that leaves a lot of debris, that it’s not our sensors that are the first to detect that, but we’re getting communications to help us understand that, just like we communicate with others,” Whiting said at an event hosted by the Mitchell Institute marking the fifth anniversary of the reestablishment of Space Command.

Whiting said he didn’t have any technical details about why the Long March 6A rocket’s upper stage broke apart, but it happened after the rocket deployed all of its payloads. “They had already released the satellites at that point, and it seems like the mission was overall successful, but all this debris gets left in orbit,” he said. “We certainly don’t want to see that kind of debris.”

Due regard

The Space Force’s 18th Space Defense Squadron, located at Vandenberg Space Force Base in California, is responsible for tracking objects in Earth orbit, maintaining a catalog of all satellites and space junk, and monitoring for potential collisions between spacecraft or debris. Space Command regularly issues warnings of conjunctions, or close approaches, between objects to commercial companies and foreign governments.

“For decades now, the United States has so cared about the space domain that we have made available the vast majority of tracking data that we have, for free, for the world,” Whiting said. “Every day, we screen every active satellite against all that debris, and we provide notifications out to everyone, including the Chinese and Russians.

“People sometimes ask, ‘Well, why do you do that?’ Well, it’s because we don’t want satellites to run into pieces of debris and create more debris. So we think it’s really important, and we have a set of responsible behaviors that we follow each and every day. We provide these notifications to the Chinese,” Whiting said.

The Commerce Department plans to take over some of the military’s role in space traffic management, but Space Command will maintain its own catalog and will remain responsible for working with foreign militaries on space debris matters, according to Whiting.

After nearly every flight, the upper stage of this rocket breaks apart in orbit.

The upper stage from a Chinese rocket that launched a batch of Internet satellites Tuesday has broken apart in space, creating a debris field of at least 700 objects in one of the most heavily-trafficked zones in low-Earth orbit.

US Space Command, which tracks objects in orbit with a network of radars and optical sensors, confirmed the rocket breakup Thursday. Space Command initially said the event created more than 300 pieces of trackable debris. The military’s ground-based radars are capable of tracking objects larger than 10 centimeters (4 inches).

Later Thursday, LeoLabs, a commercial space situational awareness company, said its radars detected at least 700 objects attributed to the Chinese rocket. The number of debris fragments could rise to more than 900, LeoLabs said.

The culprit is the second stage of China’s Long March 6A rocket, which lifted off Tuesday with the first batch of 18 satellites for a planned Chinese megaconstellation that could eventually number thousands of spacecraft. The Long March 6A’s second stage apparently disintegrated after placing its payload of 18 satellites into a polar orbit.

Space Command said in a statement it has “observed no immediate threats” and “continues to conduct routine conjunction assessments to support the safety and sustainability of the space domain.” According to LeoLabs, radar data indicated the rocket broke apart at an altitude of 503 miles (810 kilometers) at approximately 4: 10 pm EDT (20: 10 UTC) on Tuesday, around 13-and-a-half hours after it lifted off from northern China.

At this altitude, it will take decades or centuries for the wispy effect of aerodynamic drag to pull the debris back into the atmosphere. As the objects drift lower, their orbits will cross paths with SpaceX’s Starlink Internet satellites, the International Space Station and other crew spacecraft, and thousands more pieces of orbital debris, putting commercial and government satellites at risk of collision.

A new debris field of nearly 1,000 objects would be a significant addition to the approximately 46,000 objects Space Command tracks in Earth orbit. According to statistics compiled by Jonathan McDowell, an astrophysicist who monitors global launch and spaceflight activity, this would rank in the top five of all debris-generation events since the dawn of the Space Age.

This rocket has a track record

The medium-class Long March 6A rocket has launched seven times since debuting in March 2022, and military and commercial satellite tracking organizations have reported several breakups of the rocket’s upper stage. In November 2022, a Long March 6A upper stage disintegrated in orbit, creating a debris field of more than 500 trackable objects, according to NASA’s Orbital Debris Program Office.

Commercial satellite tracking companies observed smaller debris fields following several other Long March 6A flights this year.

In its space environment statistics report, the European Space Agency says there have been more than 640 “breakups, explosions, collisions, or anomalous events resulting in fragmentation” in orbit. So these things happen frequently. But it’s not clear what makes the Long March 6A, which has a relatively short flight history, particularly vulnerable to creating debris.

Enlarge / A Long March 6A rocket launches the first 18 Internet satellites for China’s Qianfan, or Thousand Sails, broadband network.

Most rockets operating today either reignite their engines to reenter the atmosphere after deploying their payloads, or if that’s not feasible, they “passivate” themselves to empty their propellant tanks and drain their batteries to reduce the risk of an explosion.

In a report last year, NASA’s Orbital Debris Program Office said the Long March 6A upper stage has a mass of about 5,800 kilograms (12,800 pounds) without kerosene and liquid oxygen propellants. It is powered by a single YF-115 engine.

The launch Tuesday began the deployment of China’s “Thousand Sails” Internet network, which will initially consist of 1,296 satellites, with the possibility to expand to more than 14,000 spacecraft. This will require numerous launches, some of which will presumably use the Long March 6A.

“If even a fraction of the launches needed to field this Chinese megaconstellation generate as much debris as this first launch, the result would be a notable addition to the space debris population in LEO (low-Earth orbit),” said Audrey Schaffer, vice president of strategy and policy at Slingshot Aerospace, a commercial satellite tracking and analytics firm.

China has been responsible for several space debris incidents beyond the latest problems with the Long March 6A rocket. In 2007, China destroyed one of its own spacecraft in an anti-satellite missile test. This was the worst-ever instance of creating space debris, resulting in more than 3,000 trackable objects, and an estimate 150,000 or more smaller fragments.

On four occasions from 2020 through 2022, the massive core stage of China’s heavy-lift Long March 5B rocket has reentered the atmosphere in an uncontrolled manner, raising concerns that falling debris could put people and property at risk on Earth.

China plans more flights with its Long March 5B and Long March 6A rockets. China continued flying the Long March 5B rocket despite the risk it posed to people on the ground. Debris fields in orbit, however, don’t directly threaten any people on Earth, but they do raise the risk to satellites of all nations, including China’s own spacecraft.

“Events like this highlight the importance of adherence to existing space debris mitigation guidelines to reduce the creation of new space debris and underscore the need for robust space domain awareness capabilities to rapidly detect, track, and catalog newly-launched space objects so they can be screened for potential conjunctions,” Schaffer said in a statement.

This story was updated with the detection of additional debris fragments by LeoLabs.

United Launch Alliance delivered a classified US military payload to orbit Tuesday for the last time with an Atlas V rocket, ending the Pentagon’s use of Russian rocket engines as national security missions transition to all-American launchers.

The Atlas V rocket lifted off from Cape Canaveral Space Force Station in Florida at 6: 45 am EDT (10: 45 UTC) Tuesday, propelled by a Russian-made RD-180 engine and five strap-on solid-fueled boosters in its most powerful configuration. This was the 101st launch of an Atlas V rocket since its debut in 2002, and the 58th and final Atlas V mission with a US national security payload since 2007.

The US Space Force’s Space Systems Command confirmed a successful conclusion to the mission, code-named USSF-51, on Tuesday afternoon. The rocket’s Centaur upper stage released the top secret USSF-51 payload about seven hours after liftoff, likely in a high-altitude geostationary orbit over the equator. The military did not publicize the exact specifications of the rocket’s target orbit.

“What a fantastic launch and a fitting conclusion for our last national security space Atlas V (launch),” said Walt Lauderdale, USSF-51 mission director at Space Systems Command, in a post-launch press release. “When we look back at how well Atlas V met our needs since our first launch in 2007, it illustrates the hard work and dedication from our nation’s industrial base. Together, we made it happen, and because of teams like this, we have the most successful and thriving launch industry in the world, bar none.”

RD-180’s long goodbye

The launch Tuesday morning was the end of an era born in the 1990s when US government policy allowed Lockheed Martin, the original developer of the Atlas V, to use Russian rocket engines during its first stage. There was a widespread sentiment in the first decade after the fall of the Soviet Union that the United States and other Western nations should partner with Russia to keep the country’s aerospace workers employed and prevent “rogue states” like Iran or North Korea from hiring them.

At the time, the Pentagon was procuring new rockets to replace legacy versions of the Atlas, Delta, and Titan rocket families, which had been in service since the late 1950s or early 1960s.

Ultimately, the Air Force chose Lockheed Martin’s Atlas V and Boeing’s Delta IV rocket for development in 1998. The Atlas V, with its Russian main engine, was somewhat less expensive than the Delta IV and the more successful of the two designs. After Tuesday’s launch, 15 more Atlas V rockets are booked to fly payloads for commercial customers and NASA, mainly for Amazon’s Kuiper network and Boeing’s Starliner crew spacecraft. The 45th and final Delta IV launch occurred in April.

Boeing and Lockheed Martin merged their rocket divisions in 2006 to form a 50-50 joint venture named United Launch Alliance, which became the sole contractor certified to carry large US military satellites to orbit until SpaceX started launching national security missions in 2018.

SpaceX filed a lawsuit in 2014 to protest the Air Force’s decision to award ULA a multibillion-dollar sole-source contract for 36 Atlas V and Delta IV rocket booster cores. The litigation started soon after Russia’s military occupation and annexation of Crimea, which prompted US government sanctions on prominent Russian government officials, including Dmitry Rogozin, then Russia’s deputy prime minister and later the head of Russia’s space agency.

Rogozin, known for his bellicose but usually toothless rhetoric, threatened to halt exports of RD-180 engines for US military missions on the Atlas V. That didn’t happen until Russia finally stopped engine exports to the United States in 2022, following its full-scale invasion of Ukraine. At that point, ULA already had all the engines it needed to fly out all of its remaining Atlas V rockets. This export ban had a larger effect on Northrop Grumman’s Antares rocket, which also used Russian engines, forcing the development of a brand new first stage booster with US engines.

The SpaceX lawsuit, Russia’s initial military incursions into Ukraine in 2014, and the resulting sanctions marked the beginning of the end for the Atlas V rocket and ULA’s use of the Russian RD-180 engine. The dual-nozzle RD-180, made by a Russian company named NPO Energomash, consumes kerosene and liquid oxygen propellants and generates 860,000 pounds of thrust at full throttle.

Breaking barriers —

Agreement marks the largest investment in space-based capabilities in NATO’s history.

During their summit in Washington, DC, this week, NATO member states committed more than $1 billion to improve the sharing of intelligence from national and commercial reconnaissance satellites.

The agreement is a further step toward integrating space assets into NATO military commands. It follows the bloc’s adoption of an official space policy in 2019, which recognized space as a fifth war-fighting domain alongside air, land, maritime, and cyberspace. The next step was the formation of the NATO Space Operations Center in 2020 to oversee space support for NATO military operations.

On June 25, NATO announced the establishment of a “space branch” in its Allied Command Transformation, which identifies trends and incorporates emerging capabilities into the alliance’s security strategy.

Breaking down barriers

The new intelligence-sharing agreement was signed on July 9 by representatives from 17 NATO nations, including the United States, to support the Alliance Persistent Surveillance from Space (APSS) program. In a statement, NATO called the agreement “the largest multinational investment in space-based capabilities in NATO’s history.”

The agreement for open sharing of intelligence data comes against the backdrop of NATO’s response to the Russian invasion of Ukraine. Space-based capabilities, including battlefield surveillance and communications, have proven crucial to both sides in the war.

“The ongoing war in Ukraine has further underscored intelligence’s growing dependence on space-based data and assets,” NATO said.

The program will improve NATO’s ability to monitor activities on the ground and at sea with unprecedented accuracy and timeliness, the alliance said in a statement. The 17 parties to the agreement pledged more than $1 billion transition the program into an implementation phase over the next five years. Six of the 17 signatories currently operate or plan to launch their own national reconnaissance satellites, while several more nations are home to companies operating commercial space-based surveillance satellites.

The APSS program won’t involve the development and launch of any NATO spy satellites. Instead, each nation will make efforts to share observations from their own government and commercial satellites.

Luxembourg, one of the smallest NATO member states, set up the APSS program with an initial investment of roughly $18 million (16.5 million euros) in 2023. At the time, NATO called the program a “data-centric initiative” aimed at bringing together intelligence information for easier dissemination among allies and breaking down barriers of secrecy and bureaucracy.

“APSS is not about creating NATO-owned and operated space assets,” officials wrote in the program’s fact sheet. “It will make use of existing and future space assets in allied countries, and connect them together in a NATO virtual constellation called ‘Aquila.'”

Another element of the program involves processing and sharing intelligence information through cloud solutions and technologies. NATO said AI analytical tools will also better manage growing amounts of surveillance data from space, and ensure decision-makers get faster access to time-sensitive observations.

“The APSS initiative may be regarded as a game changer for NATO’s intelligence, surveillance and reconnaissance. It will largely contribute to build NATO’s readiness and reduce its dependency on other intelligence and surveillance capabilities,” said Ludwig Decamps, general manager of the NATO Communications and Information Agency.

“Lane 1 serves our commercial-like missions that can accept more risk.”

After years of lobbying, protests, and bidding, Jeff Bezos’s space company is now a military launch contractor.

The US Space Force announced Thursday that Blue Origin will compete with United Launch Alliance and SpaceX for at least 30 military launch contracts over the next five years. These launch contracts have a combined value of up to $5.6 billion.

This is the first of two major contract decisions the Space Force will make this year as the military seeks to foster more competition among its roster of launch providers and reduce its reliance on just one or two companies.

For more than a decade following its formation from the merger of Boeing and Lockheed Martin rocket programs, ULA was the sole company certified to launch the military’s most critical satellites. This changed in 2018, when SpaceX started launching national security satellites for the military. In 2020, despite protests from Blue Origin seeking eligibility, the Pentagon selected ULA and SpaceX to continue sharing launch duties.

The National Security Space Launch (NSSL) program is in charge of selecting contractors to deliver military surveillance, navigation, and communications satellites into orbit.

Over the next five years, the Space Force wants to tap into new launch capabilities from emerging space companies. The procurement approach for this new round of contracts, known as NSSL Phase 3, is different from the way the military previously bought launch services. Instead of grouping all national security launches into one monolithic contract, the Space Force is dividing them into two classifications: Lane 1 and Lane 2.

The Space Force’s contract announced Thursday was for Lane 1, which is for less demanding missions to low-Earth orbit. These missions include smaller tech demos, experiments, and launches for the military’s new constellation of missile-tracking and data-relay satellites, an effort that will eventually include hundreds or thousands of spacecraft managed by the Pentagon’s Space Development Agency.

This fall, the Space Force will award up to three contracts for Lane 2, which covers the government’s most sensitive national security satellites, which require “complex security and integration requirements.” These are often large, heavy spacecraft weighing many tons and sometimes needing to go to orbits thousands of miles from Earth. The Space Force will require Lane 2 contractors to go through a more extensive certification process than is required in Lane 1.

“Today marks the beginning of this innovative, dual-lane approach to launch service acquisition, whereby Lane 1 serves our commercial-like missions that can accept more risk and Lane 2 provides our traditional, full mission assurance for the most stressing heavy-lift launches of our most risk-averse missions,” said Frank Calvelli, assistant secretary of the Air Force for space acquisition and integration.

Meeting the criteria

The Space Force received seven bids for Lane 1, but only three companies met the criteria to join the military’s roster of launch providers. The basic requirement to win a Lane 1 contract was for a company to show its rocket can place at least 15,000 pounds of payload mass into low-Earth orbit, either on a single flight or over a series of flights within a 90-day period.

The bidders also had to substantiate their plan to launch the rocket they proposed to use for Lane 1 missions by December 15 of this year. A spokesperson for Space Systems Command said SpaceX proposed using their Falcon 9 and Falcon Heavy rockets, and ULA offered its Vulcan rocket. Those launchers are already flying. Blue Origin proposed its heavy-lift New Glenn rocket, slated for an inaugural test flight no earlier than September.

“As we anticipated, the pool of awardees is small this year because many companies are still maturing their launch capabilities,” said Brig. Gen. Kristin Panzenhagen, program executive officer for the Space Force’s assured access to space division. “Our strategy accounted for this by allowing on-ramp opportunities every year, and we expect increasing competition and diversity as new providers and systems complete development.”

The Space Force plans to open up the first on-ramp opportunity for Lane 1 as soon as the end of this year. Companies with medium-lift rockets in earlier stages of development, such as Rocket Lab, Relativity Space, Firefly Aerospace, and Stoke Space, will have the chance to join ULA, SpaceX, and Blue Origin in the Lane 1 pool at that time. The structure of the NSSL Phase 3 contracts allow the Pentagon to take advantage of emerging launch capabilities as soon as they become available, according to Calvelli.

In a statement, Panzenhagen said having additional launch providers will increase the Space Force’s “resiliency” in a time of increasing competition between the US, Russia, and China in orbit. “Launching more risk-tolerant satellites on potentially less mature launch systems using tailored independent government mission assurance could yield substantial operational responsiveness, innovation, and savings,” Panzenhagen said.

More competition, theoretically, will also deliver lower launch prices to the Space Force. SpaceX and Blue Origin rockets are partially reusable, while ULA eventually plans to recover and reuse Vulcan main engines.

Over the next five years, Space Systems Command will dole out fixed-price “task orders” to ULA, SpaceX, and Blue Origin for groups of Lane 1 missions. The first batch of missions up for awards in Lane 1 include seven launches for the Space Development Agency’s missile tracking mega-constellation, plus a task order for the National Reconnaissance Office, the government’s spy satellite agency. However, military officials require a rocket to have completed at least one successful orbital launch to win a Lane 1 task order, and Blue Origin’s New Glenn doesn’t yet satisfy this requirement.

The Space Force will pay Blue Origin $5 million for an “initial capabilities assessment” for Lane 1. SpaceX and ULA, the military’s incumbent launch contractors, will each receive $1.5 million for similar assessments.

ULA, SpaceX, and Blue Origin are also the top contenders to win Lane 2 contracts later this year. In order to compete in Lane 2, a launch provider must show it has a plan for its rockets to meet the Space Force’s stringent certification requirements by October 1, 2026. SpaceX’s Falcon 9 and Falcon Heavy are already certified, and ULA’s Vulcan is on a path to achieve this milestone by the end of this year, pending a successful second test flight in the next few months. A successful debut of New Glenn by the end of this year would put the October 2026 deadline within reach of Blue Origin.

The launch of a classified Russian military satellite last week deployed a payload that US government officials say is likely a space weapon.

In a series of statements, US officials said the new military satellite, named Kosmos 2576, appears to be similar to two previous “inspector” spacecraft launched by Russia in 2019 and 2022.

“Just last week, on May 16, Russia launched a satellite into low-Earth orbit that the United States assesses is likely a counter-space weapon presumably capable of attacking other satellites in low-Earth orbit,” said Robert Wood, the deputy US ambassador to the United Nations. “Russia deployed this new counter-space weapon into the same orbit as a US government satellite.”

Kosmos 2576 is flying in the same orbital plane as a National Reconnaissance Office (NRO) spy satellite, meaning it can regularly approach the top-secret US reconnaissance platform. The launch of Kosmos 2576 from Russia’s Plesetsk Cosmodrome on a Soyuz rocket was precisely timed to happen when the Earth’s rotation brought the launch site underneath the orbital path of the NRO spy satellite, officially designated USA 314.

The Soyuz rocket’s Fregat upper stage released Kosmos 2576 into an orbit roughly 275 miles (445 km) above Earth at an inclination of 97.25 degrees to the equator.

Conventional but concerning

So far, Kosmos 2576 is nowhere near USA 314, a bus-size spacecraft believed to carry a powerful Earth-facing telescope to capture high-resolution images for use by US intelligence agencies. This type of spacecraft is publicly known as a KH-11, or Keyhole-class, satellite, but its design and capabilities are top-secret.

It’s no surprise that the Russian military wants to get a close look in hopes of learning more about the US government’s most closely held secrets about what it does in orbit. Russian satellites have also flown near Western communications satellites in geostationary orbit, likely in an attempt to eavesdrop on radio transmissions.

Russia’s deputy foreign minister, Sergei Ryabkov, dismissed the US government’s assessment about the purpose of Kosmos 2576 as “fake news.” However, in the last few years, Russia has steered satellites into orbits intersecting with the paths of US spy platforms, and demonstrated it can take out an enemy satellite using a range of methods.

The current orbit of Kosmos 2576 will only occasionally bring it within a few hundred kilometers of the USA 314, according to Jonathan McDowell, an astrophysicist and expert tracker of spaceflight events. However, analysts expect additional maneuvers to raise the altitude Kosmos 2576 and put it into position for closer passes. This is what happened with a pair of Russian satellites launched in 2019 and 2022.

These two previous Russian satellites—Kosmos 2542 and Kosmos 2558— continually flew within a few dozen kilometers of two other NRO satellites—USA 245 and USA 326—in low-Earth orbit. In a post on the social media platform X, McDowell wrote that the Russian military craft “shadowed US satellites at a large distance but have not interfered with them.”

Because of this, McDowell wrote that he is “highly skeptical” that Kosmos 2576 is an anti-satellite weapon.

But one of these Russian satellites, Kosmos 2542, released a smaller sub-satellite, designated Kosmos 2543, which made its own passes near the USA 245 spacecraft, a KH-11 imaging satellite similar to USA 314. At one point, satellite trackers noticed USA 245 made a slight change to orbit. Its Russian pursuer later made a similar orbit adjustment to keep up.

In 2020, Kosmos 2543 backed off from USA 245. Once well away from the NRO satellite, Kosmos 2543 ejected a mysterious projectile into space at a speed fast enough to damage any target in its sights.

At the time, US Space Command called the event a “non-destructive test of a space-based anti-satellite weapon.” The projectile fired from Kosmos 2543 at a relative velocity of some 400 mph (700 km per hour), according to McDowell’s analysis of publicly available satellite tracking data.

The US military has identified China as its most significant strategic adversary in the coming decades. Most aspects of Russia’s space program are in decline, but it still boasts formidable anti-satellite capabilities. Russia intentionally destroyed one of its retired satellites in orbit with a ground-based missile in 2021. The Russian military has also deployed several Peresvet laser units capable of disabling a satellite in orbit. A Russian cyberattack at the start of the invasion of Ukraine in 2022 knocked a commercial satellite communications network offline.

Most recently, US government officials have claimed Russia is developing a nuclear anti-satellite weapon. Russian officials also denied this. But Russia vetoed a UN Security Council resolution last month reiterating language from the 1967 Outer Space Treaty banning weapons of mass destruction in orbit.

The US military has its own fleet of inspector satellites in orbit to track what other nations are doing in space. The Space Force’s development of any offensive military capability in space is classified.

“The space domain is much more challenging today than it was a number a number of years ago,” said Air Force Gen. Charles “CQ” Brown, chairman of the joint chiefs of staff, in an event Wednesday hosted by the Atlantic Council. “We looked at it as a very benign environment, where you didn’t have to worry about conflicts in space. As a matter of fact, naming space as a warfighting domain was kind of forbidden, but that’s changed, and it’s been changed based what our adversaries are doing in space.”

“We don’t want to have our satellites … be challenged,” Brown said. “So we want to make sure that we have the capabilities to defend ourselves, no matter what domain we’re in, whether it’s in the space domain, air, land, or maritime. That’s where our focus is as a military, in making sure we’re investing to provide the capabilities and expertise to do that.”

“The United States assesses that Russia is developing a new satellite carrying a nuclear device.”

Russia vetoed a United Nations Security Council resolution Wednesday that would have reaffirmed a nearly 50-year-old ban on placing weapons of mass destruction into orbit, two months after reports Russia has plans to do just that.

Russia’s vote against the resolution was no surprise. As one of the five permanent members of the Security Council, Russia has veto power over any resolution that comes before the body. China abstained from the vote, and 13 other members of the Security Council voted in favor of the resolution.

If it passed, the resolution would have affirmed a binding obligation in Article IV of the 1967 Outer Space Treaty, which says nations are “not to place in orbit around the Earth any objects carrying nuclear weapons or any other kinds of weapons of mass destruction.”

Going nuclear

Russia is one of 115 parties to the Outer Space Treaty. The Security Council vote Wednesday follows reports in February that Russia is developing a nuclear anti-satellite weapon.

“The United States assesses that Russia is developing a new satellite carrying a nuclear device,” said Jake Sullivan, President Biden’s national security advisor. “We have heard President Putin say publicly that Russia has no intention of deploying nuclear weapons in space. If that were the case, Russia would not have vetoed this resolution.”

The United States and Japan proposed the joint resolution, which also called on nations not to develop nuclear weapons or any other weapons of mass destruction designed to be placed into orbit around the Earth. In a statement, US and Japanese diplomats highlighted the danger of a nuclear detonation in space. Such an event would have “grave implications for sustainable development, and other aspects of international peace and security,” US officials said in a press release.

With its abstention from the vote, “China has shown that it would rather defend Russia as its junior partner, than safeguard the global nonproliferation regime,” said Linda Thomas-Greenfield, the US ambassador to the UN.

US government officials have not offered details about the exact nature of the anti-satellite weapon they say Russia is developing. A nuclear explosion in orbit would destroy numerous satellites—from many countries—and endanger astronauts. Space debris created from a nuclear detonation could clutter orbital traffic lanes needed for future spacecraft.

The Soviet Union launched more than 30 military satellites powered by nuclear reactors. Russia’s military space program languished in the first couple of decades after the fall of the Soviet Union, and US intelligence officials say it still lags behind the capabilities possessed by the US Space Force and the Chinese military.

Russia’s military funding has largely gone toward the war in Ukraine for the last two years, but Putin and other top Russian officials have raised threats of nuclear force and attacks on space assets against adversaries. Russia’s military launched a cyberattack against a commercial satellite communications network when it invaded Ukraine in 2022.

Russia has long had an appetite for anti-satellite (ASAT) weapons. The Soviet Union experimented with “co-orbital” ASATs in the 1960s and 1970s. When deployed, these co-orbital ASATs would have attacked enemy satellites by approaching them and detonating explosives or using a grappling arm to move the target out of orbit.

Russian Ministry of Defense

In 1987, the Soviet Union launched an experimental weapons platform into orbit to test laser technologies that could be used against enemy satellites. Russia shot down one of its own satellites in 2021 in a widely condemned “direct ascent” ASAT test. This Russian direct ascent ASAT test followed demonstrations of similar capability by China, the United States, and India. Russia’s military has also demonstrated satellites over the last decade that could grapple onto an adversary’s spacecraft in orbit, or fire a projectile to take out an enemy satellite.

These ASAT capabilities could destroy or disable one enemy satellite at a time. The US Space Force is getting around this threat by launching large constellations of small satellites to augment the military’s much larger legacy communications, surveillance, and missile warning spacecraft. A nuclear ASAT weapon could threaten an entire constellation or render some of space inaccessible due to space debris.

Russia’s ambassador to the UN, Vasily Nebenzya, called this week’s UN resolution “an unscrupulous play of the United States” and a “cynical forgery and deception.” Russia and China proposed an amendment to the resolution that would have banned all weapons in space. This amendment got the support of about half of the Security Council but did not pass.

Outside the 15-member Security Council, the original resolution proposed by the United States and Japan won the support of more than 60 nations as co-sponsors.

“Regrettably, one permanent member decided to silence the critical message we wanted to send to the present and future people of the world: Outer space must remain a domain of peace, free of weapons of mass destruction, including nuclear weapons,” said Kazuyuki Yamazaki, Japan’s ambassador to the UN.

The Space Force is planning what could be the first military exercise in orbit

The US Space Force announced Thursday it is partnering with two companies, Rocket Lab and True Anomaly, for a first-of-its-kind mission to demonstrate how the military might counter “on-orbit aggression.”

On this mission, a spacecraft built and launched by Rocket Lab will chase down another satellite made by True Anomaly, a Colorado-based startup. “The vendors will exercise a realistic threat response scenario in an on-orbit space domain awareness demonstration called Victus Haze,” the Space Force’s Space Systems Command said in a statement.

This threat scenario could involve a satellite performing maneuvers that approach a US spacecraft or a satellite doing something else unusual or unexpected. In such a scenario, the Space Force wants to have the capability to respond, either to deter an adversary from taking action or to defend a US satellite from an attack.

Going up to take a look

“When another nation puts an asset up into space and we don’t quite know what that asset is, we don’t know what its intent is, we don’t know what its capabilities are, we need the ability to go up there and figure out what this thing is,” said Gen. Michael Guetlein, the Space Force’s vice chief of space operations.

This is what the Space Force wants to demonstrate with Victus Haze. For this mission, True Anomaly’s spacecraft will launch first, posing as a satellite from a potential adversary, like China or Russia. Rocket Lab will have a satellite on standby to go up and inspect True Anomaly’s spacecraft and will launch it when the Space Force gives the launch order.

“Pretty sporty,” said Even Rogers, co-founder and CEO of True Anomaly.

Then, if all goes according to plan, the two spacecraft will switch roles, with True Anomaly’s Jackal satellite actively maneuvering around Rocket Lab’s satellite. According to the Space Force, True Anomaly and Rocket Lab will deliver their spacecraft no later than the fall of 2025.

“If a near-peer competitor makes a movement, we need to have it in our quiver to make a counter maneuver, whether that be go up and do a show of force or go up and do space domain awareness or understand the characterization of the environment—what’s going on?” Guetlein said.

Victus Haze is the next in a series of military missions dedicated to validating Tactically Responsive Space (TacRS) capabilities. With these efforts, the Space Force and its commercial partners have shown how they can compress the time it takes to prepare and launch a satellite.

Last year, the Space Force partnered with Firefly Aerospace and Millennium Space Systems on the Victus Nox mission. The Victus Nox satellite was built and tested in less than a year and then readied for launch in less than 60 hours. Firefly successfully launched the spacecraft on its Alpha rocket 27 hours after receiving launch orders from the Space Force, a remarkable achievement in an industry where satellites take years to build and launch campaigns typically last weeks or months.

“We no longer have the luxury of time to wait years, even 10 or 15 years, to deliver some of these capabilities.” Guetlein said in a discussion in January hosted by the Center for Strategic and International Studies. “A tactically relevant timeline is a matter of weeks, days, or even hours.”

“Victus Haze is about continuing to break those paradigms and to show how we would rapidly put up a space domain awareness capability and operate it in real time against a threat,” Guetlein said.

The Victus Haze mission is more complicated than Victus Nox, involving two prime contractors, two spacecraft, and two rocket launches from different spaceports, all timed to occur with short timelines “to keep the demonstration as realistic as possible,” a Space Force spokesperson told Ars.

“This demonstration will ultimately prepare the United States Space Force to provide future forces to combatant commands to conduct rapid operations in response to adversary on-orbit aggression,” Space Systems Command said in a statement.

Delta 389 —

“It is bittersweet to see the last one, but there are great things ahead.”

United Launch Alliance

The final flight of United Launch Alliance’s Delta IV Heavy rocket took off Tuesday from Cape Canaveral, Florida, with a classified spy satellite for the National Reconnaissance Office.

The Delta IV Heavy, one of the world’s most powerful rockets, launched for the 16th and final time Tuesday. It was the 45th and last flight of a Delta IV launcher and the final rocket named Delta to ever launch, ending a string of 389 missions dating back to 1960.

United Launch Alliance (ULA) tried to launch this rocket on March 28 but aborted the countdown about four minutes prior to liftoff due to trouble with nitrogen pumps at an off-site facility at Cape Canaveral. The nitrogen is necessary for purging parts inside the Delta IV rocket before launch, reducing the risk of a fire or explosion during the countdown.

The pumps, operated by Air Liquide, are part of a network that distributes nitrogen to different launch pads at the Florida spaceport. The nitrogen network has caused problems before, most notably during the first launch campaign for NASA’s Space Launch System rocket in 2022. Air Liquide did not respond to questions from Ars.

A flawless liftoff

With a solution in place, ULA gave the go-ahead for another launch attempt Tuesday. After a smooth countdown, the final Delta IV Heavy lifted off from Cape Canaveral Space Force Station at 12: 53 pm EDT (16: 53 UTC).

Three hydrogen-fueled RS-68A engines made by Aerojet Rocketdyne flashed to life in the final seconds before launch and throttled up to produce more than 2 million pounds of thrust. The ignition sequence was accompanied by a dramatic hydrogen fireball, a hallmark of Delta IV Heavy launches, that singed the bottom of the 235-foot-tall (71.6-meter) rocket, turning a patch of its orange insulation black. Then, 12 hold-down bolts fired and freed the Delta IV Heavy for its climb into space with a top-secret payload for the US government’s spy satellite agency.

Heading east from Florida’s Space Coast, the Delta IV Heavy appeared to perform well in the early phases of its mission. After fading from view from ground-based cameras, the rocket’s two liquid-fueled side boosters jettisoned around four minutes into the flight, a moment captured by onboard video cameras. The core stage engine increased power to fire for a couple more minutes. Nearly six minutes after liftoff, the core stage was released, and the Delta IV upper stage took over for a series of burns with its RL10 engine.

At that point, ULA cut the public video and audio feeds from the launch control center, and the mission flew into a news blackout. The final portions of rocket launches carrying National Reconnaissance Office (NRO) satellites are usually performed in secret.

In all likelihood, the Delta IV Heavy’s upper stage was expected to fire its engine at least three times to place the classified NRO satellite into a circular geostationary orbit more than 22,000 miles (nearly 36,000 kilometers) over the equator. In this orbit, the spacecraft will move in lock-step with the planet’s rotation, giving the NRO’s newest spy satellite constant coverage over a portion of the Earth.

It will take about six hours for the rocket’s upper stage to deploy its payload into this high-altitude orbit and only then will ULA and the NRO declare the launch a success.

Eavesdropping from space

While the payload is classified, experts can glean a few insights from the circumstances of its launch. Only the largest NRO spy satellites require a launch on a Delta IV Heavy, and the payload on this mission is “almost certainly” a type of satellite known publicly as an “Advanced Orion” or “Mentor” spacecraft, according to Marco Langbroek, an expert Dutch satellite tracker.

The Advanced Orion satellites require the combination of the Delta IV Heavy rocket’s lift capability, long-duration upper stage, and huge, 65-foot-long (19.8-meter) trisector payload fairing, the largest payload enclosure of any operational rocket. In 2010, Bruce Carlson, then-director of the NRO, referred to the Advanced Orion platform as the “largest satellite in the world.”

When viewed from Earth, these satellites shine with the brightness of an eighth-magnitude star, making them easily visible with small binoculars despite their distant orbits, according to Ted Molczan, a skywatcher who tracks satellite activity.

“The satellites feature a very large parabolic unfoldable mesh antenna, with estimates of the size of this antenna ranging from 20 to 100 (!) meters,” Langbroek writes on his website, citing information leaked by Edward Snowden.

The purpose of these Advanced Orion satellites, each with mesh antennas that unfurl to a diameter of up to 330 feet (100 meters), is to listen in on communications and radio transmissions from US adversaries, and perhaps allies. Six previous Delta IV Heavy missions also likely launched Advanced Orion or Mentor satellites, giving the NRO a global web of listening posts parked high above the planet.

With the last Delta IV Heavy off the launch pad, ULA has achieved a goal of its corporate strategy sent into motion a decade ago, when the company decided to retire the Delta IV and Atlas V rockets in favor of a new-generation rocket named Vulcan. The first Vulcan rocket successfully launched in January, so the last few months have been a time of transition for ULA, a 50-50 joint venture owned by Boeing and Lockheed Martin.

“This is such an amazing piece of technology: 23 stories tall, half a million gallons of propellant, two and a quarter million pounds of thrust, and the most metal of all rockets, setting itself on fire before it goes to space,” Bruno said of the Delta IV Heavy before its final launch. “Retiring it is (key to) the future, moving to Vulcan, a less expensive, higher-performance rocket. But it’s still sad.”

“Everything that Delta has done … is being done better on Vulcan, so this is a great evolutionary step,” said Bill Cullen, ULA’s launch systems director. “It is bittersweet to see the last one, but there are great things ahead.”

Pentagon calls for tighter integration between military and commercial space

A strategy document released by the Pentagon this week lays out where the US military can most effectively rely on the commercial space industry and what missions should remain in government hands.

“This marks a new effort to harness the remarkable innovation of the commercial space sector to enhance our resilience and strengthen integrated deterrence as a department,” said John Plumb, assistant secretary of defense for space policy.

The Space Force already buys a lot from the commercial space industry. The military doesn’t build or own satellite launch vehicles—those come from commercial companies. While the Space Force operates government-owned reconnaissance and surveillance satellites, it also buys supplementary data and imagery from the commercial industry.

“To protect our men and women in uniform and to ensure the space services they rely on will be available when needed, the department has a responsibility to leverage all tools available, and those tools include commercial solutions,” Plumb said Tuesday. “From launch to space domain awareness to satellite communications and more, the commercial sector’s ability to innovate, to scale production and to rapidly refresh their technology is opening the door to all kinds of possibilities.”

The Pentagon defines the commercial space sector as companies that develop capabilities for sale on the commercial market, where the military is one of many customers. This is separate from the Pentagon’s procurement of government-owned airplanes and satellites from the defense industry.

Ripe for exploitation

Build or buy is an age-old question facing everyone from homeowners to billion-dollar enterprises. When it comes to space, the Pentagon is buying more than ever. The military’s new strategy document outlines 13 mission areas for national security space, and while the commercial space industry is rapidly growing, the Pentagon predominately buys commercial services in only one of those mission areas.

“Out of those 13, the only that’s clearly primarily commercial now is SAML.. which is Space Access, Mobility and Logistics, and space access is launch,” Plumb said. “So SpaceX, Firefly, Rocket Lab, all these different companies doing commercial launch, that’s where the commercial sector clearly can provide services.”

Currently, the military classifies six mission areas as a hybrid of government and commercial capabilities:

  • Cyberspace operations
  • Satellite communications
  • Spacecraft operations,
  • Intelligence, surveillance, and reconnaissance
  • Space domain awareness (tracking of space objects)
  • Environmental monitoring.

In the remaining six mission areas, “a preponderance of functions must be performed by the government, while a select few could be performed by the commercial sector,” officials wrote in the commercial space strategy. In these areas, there is not yet a viable commercial market outside of the government, or commercial capabilities don’t match the government’s needs. These areas include:

  • Command and control (including nuclear command, control, and communications)
  • Electromagnetic warfare
  • Nuclear detonation detection
  • Missile warning
  • Position, navigation, and timing (GPS).

A major tenet of the commercial space strategy is for the military to support the development of new commercial space capabilities. This could involve supporting technology demonstrations and funding scientific research. Over time, new technology and new markets could bring more mission areas into the hybrid or commercial lists.

“I think what this strategy hopes to do is say, yes, continue working on bringing commercial entities in,” Plumb said. “This is actually a thing we want you to do, not just a thing you should be experimenting with.”

A sleuthing enthusiast says he found the US military’s X-37B spaceplane

Found —

Officials didn’t disclose details about the X-37B’s orbit after its December launch.

It turns out some of the informed speculation about the US military’s latest X-37B spaceplane mission was pretty much spot-on.

When the semi-classified winged spacecraft launched on December 28, it flew into orbit on top of a SpaceX Falcon Heavy rocket, which is much larger than the Atlas V and Falcon 9 rockets used to launch the X-37B on its previous missions.

This immediately sparked speculation that the X-37B would reach higher altitudes than its past flights, which remained in low-Earth orbit at altitudes of a few hundred miles. A discovery from Tomi Simola, a satellite tracking hobbyist living near Helsinki, Finland, appears to confirm this suspicion.

On Friday, Simola reported on social media and on SeeSat-L, a long-running online forum of satellite tracking enthusiasts, that he detected an unidentified object using a sky-watching camera. The camera is designed to continuously observe a portion of the sky to detect moving objects in space. A special software program helps identify known and unknown objects.

“Exciting news!” Simola posted on social media. “Orbital Test Vehicle 7 (OTV-7), which was launched to classified orbit last December, was seen by my SatCam! Here are images from the last two nights!”

— Tomppa 🇺🇦 (@tomppa77) February 9, 2024

Mike McCants, one of the more experienced satellite observers and co-administrator of the SeeSat-L forum, agreed with Simola’s conclusion that he found the X-37B spaceplane.

“Congrats to Tomi Simola for locating the secret X-37B spaceplane,” posted Jonathan McDowell, an astrophysicist and widely respected expert in spaceflight activity.

Higher than ever

Amateur observations of the spaceplane indicate it is flying in a highly elliptical orbit ranging between 201 and 24,133 miles in altitude (323 and 38,838 kilometers). The orbit is inclined 59.1 degrees to the equator.

This is not far off the predictions from the hobbyist tracking community before the launch in December. At that time, enthusiasts used information about the Falcon Heavy’s launch trajectory and drop zones for the rocket’s core booster and upper stage to estimate the orbit it would reach with the X-37B spaceplane.

The Space Force has not released any information about the orbit of the X-37B. While it took hobbyists about six weeks to find the X-37B on this mission, it typically took less time for amateur trackers to locate it when it orbited at lower altitudes on its previous missions. Despite the secrecy, it’s difficult to imagine the US military’s adversaries in China and Russia didn’t already know where the spaceplane was flying.

Military officials usually don’t disclose details about the X-37B’s missions while they are in space, providing updates only before each launch and then after each landing.

This is the seventh flight of an X-3B spaceplane since the first one launched in 2010. In a statement before the launch in December, the Space Force said this flight of the X-37B is focused on “a wide range of test and experimentation objectives.” Flying in “new orbital regimes” is among the test objectives, military officials said.

The military has two Boeing-built X-37B spaceplanes, or Orbital Test Vehicles, in its inventory. They are reusable and designed to launch inside the payload fairing of a conventional rocket, spend multiple years in space with the use of solar power, and then return to Earth for a landing on a three-mile-long runway, either at Vandenberg Space Force Base in California or at NASA’s Kennedy Space Center in Florida.

It resembles a miniature version of NASA’s retired space shuttle orbiter, with wings, deployable landing gear, and black thermal protection tiles to shield its belly from the scorching heat of reentry. It measures 29 feet (about 9 meters) long, roughly a quarter of the length of NASA’s space shuttle, and it doesn’t carry astronauts.

The X-37B has a cargo bay inside the fuselage for payloads, with doors that open after launch and close before landing. There is also a service module mounted to the back end of the spaceplane to accommodate additional experiments, payloads, and small satellites that can deploy in orbit to perform their own missions.

All the Space Force has said about the payloads on the current X-37B flight is that its experiment package includes investigations into new “space domain awareness technologies.” NASA is flying an experiment on the X-37B to measure how plant seeds respond to sustained exposure to space radiation. The spaceplane’s orbit on this flight takes it through the Van Allen radiation belts.

The secrecy surrounding the X-37B has sparked much speculation about its purpose, some of which centers on ideas that the spaceplane is part of a classified weapons platform in orbit. More likely, analysts say, the X-37B is a testbed for new space technologies. The unusual elliptical orbit for this mission is similar to the orbit used for some of the Space Force’s satellites designed to detect and warn of ballistic missile launches.

McDowell said this could mean the X-37B is testing out an infrared sensor for future early warning satellites, but then he cautioned this would be “just a wild speculation.”

Speculation is about all we have to go on regarding the X-37B. But it seems we no longer need to speculate about where the X-37B is flying.
