NASA wants you to be an Astronaut.
Just as long as you have a degree or two in engineering, science or math and have worked at least three years in your field—you’re already on your way to becoming a NASA Astronaut candidate. If you’re a pilot but haven’t worked three years in your field yet, just as long as you’ve flown for 1,000 hours while in charge as the pilot then you’re good to go. Then, you have to pass the NASA physical.
NASA Space Physical Requirements
(These are according to the NASA official website.)
Distant visual acuity: 20/100 or better uncorrected, correctable to 20/20 each eye.
Blood pressure: 140/90 measured in a sitting position.
Height between 62 and 75 inches.
The applications will be open starting Dec. 14, so you have a little over a month to think about it.
To infinity, and beyond!
