Vast Space has been sued by rival Axiom Space, which alleges Vast copied its proprietary mission-planning work for a NASA private astronaut mission. Ars Technica reported on November 10, 2026, citing a NASA letter stating that Vast's submission in some locations substituted the PAM Provider for Axiom. The suit concerns competition over commercial space station work. Axiom filed a False Claims Act case in a Houston federal court on June 19, alleging Vast presented NASA with a fraudulent Mission Integration and Operations Management Plan that incorporated Axiom's information. The Justice Department declined to intervene on October 23, so Axiom is pursuing the case independently. Vast said the suit was about competition, not fraud, while Axiom said the plan is central to demonstrating a company can keep a crew safe. Ars Technica reported that how Vast obtained the document remains unanswered.
