Astronaut Ground Travel Support Act

The bill adds a new section to U.S. space law that lets the NASA Administrator authorize use of federal passenger vehicles to transport government astronauts and space flight participants. These vehicles can be government‑owned or leased cars, aircraft, boats, or similar transportation. The rides can be between the person’s home and different places they must go after a mission. The transportation must be for an “official purpose.” This is defined as travel needed for post‑mission activities such as medical research, monitoring, diagnosis, and treatment before the astronaut or space flight participant is medically cleared to drive a motor vehicle. The Chief of the Astronaut Office must approve in writing the post‑mission transportation for government astronauts and space flight participants. The bill allows the NASA Administrator to maintain, operate, and repair one or more passenger carriers specifically to provide this transportation. If an international partner astronaut or a space flight participant is not a U.S. government employee, the transportation they receive under this authority must be reimbursed to the U.S. Treasury. The NASA Administrator is required to issue regulations to carry out these rules. The bill also states that NASA may spend its available funds on this transportation even though another law (31 U.S.C. 1344(a)) normally limits the use of government vehicles for home‑to‑work travel. Finally, it updates the table of contents in the U.S. Code to add the new section on passenger carrier use for astronaut transportation.

Astronauts and space flight participants can face medical and safety risks right after returning from space, such as balance problems, fatigue, or other health issues. Having clear legal authority for NASA to drive them between their homes and medical or research facilities may reduce the chance that people who are not yet medically cleared will need to drive themselves. The bill also covers international partner astronauts and private space flight participants, who are playing a larger role in space missions. By requiring reimbursement when non‑federal personnel use this transportation, the bill sets cost‑sharing rules so that federal funds are not providing free ground travel to people who are not U.S. government employees. The full budget impact and how often the authority will be used are not stated in the bill, so the overall cost is unclear. Because it overrides a general limit on using federal vehicles for home‑to‑work type travel, the bill sets a specific exception for NASA related to space missions. This may matter for how NASA plans post‑mission support and how it coordinates with commercial spaceflight companies and foreign partners.

• Defines “official purpose” for transportation as post‑mission activities, including medical research, monitoring, diagnosis, and treatment before a person is cleared to drive.
• Allows NASA’s Administrator to authorize use of federal passenger carriers to transport government astronauts and space flight participants between their homes and various locations for these official purposes.
• Requires written approval from the Chief of the Astronaut Office for post‑mission transportation of government astronauts and space flight participants.
• Permits NASA to maintain, operate, and repair one or more passenger carriers specifically to provide such transportation.
• Requires reimbursement to the U.S. Treasury for transportation provided to international partner astronauts and space flight participants who are not U.S. government employees.
• Directs the NASA Administrator to issue regulations needed to implement these transportation rules.
• Authorizes NASA to use its available funds for this transportation “notwithstanding” 31 U.S.C. 1344(a), which ordinarily restricts use of government vehicles for home‑to‑work travel.
• Inserts a new section, 51 U.S.C. 20150, “Passenger carrier use for astronaut transportation,” into federal space law.

• The authority covers not just cars but also aircraft, boats, and similar government‑owned or leased passenger vehicles, which could include higher‑cost transportation modes.
• The definition of “mission” includes assignments for either government astronauts or space flight participants, so the support is not limited to traditional NASA civil servant astronauts.
• By using a “notwithstanding” clause against 31 U.S.C. 1344(a), the bill creates a specific carve‑out that could be cited as a model by other agencies seeking similar exceptions.
• NASA must write implementing regulations, which will determine many practical details (such as eligibility rules, documentation, and reimbursement procedures) that are not spelled out in the bill text itself.
