Marines and sailors with an eye towards the stars now have the opportunity to apply for astronaut training.

NASA sent recruitment messages to the Navy and Marine Corps on Dec. 15 that outlined what qualifications a veteran must have to apply:

–Be a US citizen;

–Have five years of active service by Aug. 2017;

–Must have earned at least a bachelor’s degree in engineering, biological science, physical science, computer science or mathematics from an accredited school;

–Must have at least three years of related, “progressively responsible” job experience following the degree, or at least 1,000 pilot hours in jet aircraft. Master’s degrees can serve as a substitute for one year of professional experience, and doctorates can substitute for three years;

–Must be able to pass the NASA long-duration astronaut physical.

Astronauts must meet rigid physical requirements in order to be sent into space. For example, an astronaut can be nor shorter than 5″2 but no taller than 6″3. In additional to simply fitting the physical bill, applicants must be skilled at flying aircraft.

If a sailor or Marine meets all of NASA’s requirement’s, they will be relocated for a two-year training period.

“Successful applicants will be assigned to positions located at Lyndon B. Johnson Space Center in Houston, Texas, and be involved in a 2-year training and evaluation program, after which they will enter the Astronaut Corps and be eligible for assignment as astronauts on future missions,” the Navy message said.
