Some astronauts are hired as civilian employees while others come over from the military. Civilian astronauts are paid according to a government scale that ranges from classifications GS-11 to GS-14.

In 2012, employees living in Houston (where astronaut training facilities are located) make a minimum of $64,724 for a GS-11 to a maximum of $141,715 for a GS-14. As employees pick up more qualifications, responsibility and experience, their salaries increase.

Military salaries were not disclosed, but NASA said those employees from the armed forces “remain in an active duty status for pay, benefits, leave, and other similar military matters.”
