How much an astronaut is paid?

The astronaut office at Johnson Space Center is a government workplace, and NASA's civilian astronauts are paid like other federal professionals: a grade on the General Schedule, a step within that grade, plus the locality adjustment for the Houston area. Pay rises with time in grade and experience rather than with flights. There is no launch bonus, no hazard premium for a spacewalk and no daily allowance for months in orbit; the salary is identical whether an astronaut is in a simulator, underwater in the training pool or aboard the International Space Station. NASA has historically classified astronaut candidates within the GS-11 to GS-14 band, and the bracket in force is printed in the vacancy announcement each time a class is recruited.

A large share of the corps comes from the armed forces and remains there on assignment. Those astronauts keep their rank, base pay, allowances and pension track, and NASA reimburses the service rather than issuing a second salary. Two people strapped side by side in the same capsule can therefore sit on completely different pay systems, with different retirement rules and different tax treatment.

ESA, JAXA and Roscosmos pay their astronauts on their own internal grade scales, again as career staff rather than per mission, with new recruits entering near the bottom of the professional range and moving up with experience. The commercial end looks different: astronauts employed by companies such as SpaceX or Axiom Space are on private-sector contracts, while the customers who buy the remaining seats are not paid at all. They are the ones paying, at prices negotiated case by case and rarely published in full.
