NASA Civilian Astronaut Pay Scale
NASA civilian astronauts are paid under the General Schedule (GS) pay system. Most astronauts start at GS-12 and advance to GS-13 or GS-14 based on experience and mission assignments. A GS-12 astronaut earns roughly $73,000 to $85,000 per year, while GS-13 astronauts can reach around $100,000 to $120,000, and GS-14 pay can exceed $140,000 depending on location and step. These figures reflect the latest public pay tables and are the same base salaries used for other federal technical roles. You can see current GS pay tables on the Office of Personnel Management site.
NASA astronauts also receive federal benefits such as health insurance, retirement contributions, and locality pay adjustments that vary by city. Military astronauts on detailed duty retain their military pay and benefits, which can differ from the civilian GS scale. In 2025, the highest-paid NASA astronauts typically hold GS-14 or GS-15 positions with many years of service and multiple mission assignments.
Private Astronaut Missions and Contractor Pay
Private astronaut missions to the ISS, such as those flown by SpaceX and Axiom Space, involve different compensation structures. Companies like SpaceX do not publicly list individual astronaut salaries, but mission costs and contractor pay are often tied to fixed-price contracts and commercial agreements. Axiom Space and other providers have published mission pricing that can reach tens of millions of dollars per seat, which covers training, launch services, and ground support.
For NASA, the agency pays private companies under contracts such as the Commercial Crew Program to transport astronauts and cargo to the ISS. These contracts set fixed prices for services rather than individual astronaut wages. Public filings and contract announcements show how NASA allocates funds for crewed missions and how companies structure internal pay for their astronauts and mission specialists.
ISS Astronaut Compensation Compared to Other Roles
Compared to other federal employees with similar education and experience, astronaut pay is competitive but not unusually high relative to the years of training and risk involved. Military astronauts on active duty can earn additional flight pay and hazard pay on top of their base military compensation. Civilian astronauts may also receive retention incentives and special pay allowances based on role and assignment.
When factoring in private astronaut missions, the economics shift toward mission fees and company contracts rather than individual salary. For example, companies flying private astronauts to the ISS charge per-seat fees that cover training, medical certification, and mission integration. These fees are often reported in contract announcements and industry analyses rather than as individual paychecks.
