Here's how much a US astronaut can earn working for NASA

By Dave Mosher

As entrepreneurs like SpaceX founder Elon Musk launch increasingly powerful rockets, call for a new space race, and prepare to send astronauts into space for the first time, it's an exciting time to think of joining NASA's ranks. 

But to even think of applying to be an astronaut, you must first pass a stringent list of requirements, including being a US citizen, having an accredited college degree in science, engineering, or mathematics, and three years of professional experience or 1,000 piloting hours. 

Then you have to go through a grueling selection process that is about 74 times harder than getting into Harvard University: NASA selects a new astronaut class once every couple of years, and picked only 12 of 18,300 applicants in 2017. 

So how much does NASA compensate its astronauts for their experience, extensive training, and willingness to risk their lives to explore space? 

According to a frequently asked questions page on NASA's website, the annual salary is "based on the Federal Government's General Schedule pay scale for grades GS-12 through GS-13." 

Such grades are used to determine how much white-collar career employees are paid across many government agencies, and they are further broken down into steps ranging from 1 through 10, which are based on acceptable performance and years of service.
