Astronaut Ground Travel Support Act

This bill allows NASA to use government-owned vehicles (like cars or vans) to transport astronauts and international space travelers after missions for specific medical reasons. It directly affects NASA astronauts and international partners who need post-mission medical checks before being cleared to drive. The key provision lets NASA's Administrator authorize this ground transportation - such as for medical monitoring or treatment - after obtaining written approval from the Astronaut Office Chief, using existing government vehicles without new funding. Non-U.S. personnel must reimburse the government for these services.
