&quot;Salaries for civilian Astronaut Candidates are based on the Federal Government’s General Schedule pay scales for grades GS-11 through GS-14&quot;<p>From <a href="http:&#x2F;&#x2F;www.federaljobs.net&#x2F;salarybase.htm#SALARY_TABLE_2015-GS" rel="nofollow">http:&#x2F;&#x2F;www.federaljobs.net&#x2F;salarybase.htm#SALARY_TABLE_2015-...</a> it sounds like civilian astronaut salaries then range from $51k to $112k per year.
