The US military has given Elon Musk's SpaceX access to its most precise data on potential collisions among satellites and other space objects. The data comes from the US Space Command's High Accuracy Catalog (Hac) and includes Vector Covariance Messages (VCMs), tracking information collected from military sensors, telescopes and radars that can detect objects as small as about 10cm in lower orbit.
SpaceX and the Space Force signed the new contract. In a statement to Breaking Defense, a Space Force spokesperson said: "The Space Force is engaging with several companies to exchange commercial data sources for access to sections of the controlled, unclassified information, high accuracy catalogue, where it provides benefit to the US government."
Critics argue the arrangement gives SpaceX an unfair advantage and could lead to a monopoly over space traffic coordination. Cole Donovan, a former employee of the Traffic Coordination System for Space (Traccs) who now works with the Stand Up for Science non-profit, said: "It's making a company the de facto source for space traffic coordination within the US. It's like giving a trucking company control of all the traffic lights, which they can switch to red whenever it's their competition's turn to go."
The move follows the administration's attempts to defund Traccs, a federal program established under the first Trump administration to take over commercial space traffic control from the defence department. The administration tried to cut the program's $65m budget in fiscal year 2026 and again proposed slashing it to nearly zero in fiscal year 2027, though Congress reinserted funding both times.
Craig Holman, Capitol Hill lobbyist for the government accountability non-profit Public Citizen, said the access was another example of the Trump administration rewarding a donor with business opportunities. "Elon Musk has bought his way into the favor of President Trump and with it, unlimited riches and lucrative government contracts in the space industry," Holman said.
A former National Oceanic and Atmospheric Administration (Noaa) official who spoke on the condition of anonymity offered a more measured view, saying SpaceX had been "remarkably responsive to space safety concerns" and did not fault Starlink for stepping into a space the government had failed to adequately address. "My greater disappointment is with the government's failure to fulfil its responsibility to establish a coherent space governance framework that provides guidance, transparency, and a level playing field for all operators," the official said.
SpaceX's Starlink subsidiary already operates about 11,000 satellites in orbit and could have as many as 20,000 in coming years. The company uses its own Stargaze system of cameras and radars mounted on Starlink satellites to track other objects, but that system can only see objects down to about half a metre in size and is less accurate than the military's system. The government will receive access to Stargaze data in return.
The commercial US space market is expected to grow to nearly $2tn in value over the next decade, and industry observers have expressed fears of a "vendor lock" scenario in which the government becomes overly reliant on SpaceX.
