Salaries for astronauts are based upon the Federal Government's General Schedule pay scale for grades GS-11 through GS-14. Grade GS-11 starts at $64,724 per year, a GS-14 has the ability to earn up to $141,715 per year.
That number changes ever so slightly depending on what we define as âprofessional spaceflightâ, but the salary for astronauts does not. Classed as civil servants, they get paid exactly the same as any other Federal Government worker and are placed on a fixed pay scale based on experience.
