How much astronaut make a year?

Asking what an astronaut earns per year is really asking a civil service question. Civilian candidates selected by NASA join the agency as federal employees and are slotted into the General Schedule, the pay system used across most professional US government posts. Their annual figure therefore follows the published grade and step tables, adjusted by locality, and rises with time in post and promotion rather than with flights logged. Nobody is paid extra for launching, and nobody is docked for a mission that slips by two years.

Military officers make up a substantial part of the corps. They remain on active duty while detailed to NASA and continue to be paid by their own service according to rank and years of service. A Navy captain assigned to Houston is paid as a Navy captain.

Astronaut candidates typically arrive with a doctorate, thousands of hours of jet time or both, and many could earn considerably more in industry. The pay reflects the public payroll they sit on, not the scarcity of the skill. It is also worth remembering how the working year is spent: language courses, survival training, spacewalk rehearsals in a large water tank, robotics, geology and long stretches of ground support between assignments.

Commercial human spaceflight has changed the picture at the edges. Companies employ their own flight crew and mission specialists on private terms, and on some private orbital flights the people aboard are customers rather than employees. Those arrangements sit outside any public pay scale and are rarely disclosed.
