Houston-based space company Axiom Space has filed a lawsuit against rival firm Vast Space, alleging that the California-based competitor submitted a fraudulent mission-planning document containing Axiom’s proprietary information to NASA. The legal clash comes as commercial space companies prepare to submit final space station proposals to the U.S. space agency by December 14.
Allegations of Fraudulent Claims
The legal action, brought under the False Claims Act, was unsealed following a November 4 court order issued by U.S. District Judge Charles Eskridge. Court documents show that Axiom accuses Long Beach-based Vast of providing NASA with planning materials that improperly incorporated Axiom’s proprietary data and operational details.
An Axiom Space spokesperson told Ars Technica that the company initiated the lawsuit on behalf of the government because public-private partnerships in human spaceflight rely on honesty, capability, original work, and integrity, adding that “presenting another company’s hard-won experience as its own does not meet that standard.”
Vast denied the fraud allegations, framing the legal dispute as an effort to stifle commercial competition. A spokesperson for Vast told Ars Technica, “NASA opened private astronaut missions to more than one provider because competition drives innovation, delivers better value for taxpayers, and keeps America leading in space. Misusing litigation against a competitor works against all of that.”
Private Astronaut Missions Program
The dispute arises from NASA’s Private Astronaut Missions program, which was launched in 2019. The initiative allows private entities to coordinate missions carrying up to four astronauts to visit the International Space Station.
Designed to stimulate commercial operations in low-Earth orbit, the program gives private aerospace firms hands-on flight experience. Industry participants view these missions as a crucial stepping stone toward securing NASA contracts to build and operate commercial space stations intended to take flight in the 2030s.
