Having worked for NASA in the past...and having hung out with test pilots and astronaut candidates, the following may help.<br /><br />1. 4 yr dregree from a recognized college/university. 2yr assoc degree will get by (maybe) if it is heavy in science/math...top grades a must!<br /><br />2. "Umpth-tha umpth" hrs of stick time not required for payload specialists. (some flight time is nice) Fixed wing not required, I know two serious candidates, and one astronaut with helo time and only some fixed wing time. <br /><br />3. Military experience a plus, officer not necessarily a preference. (yes folks they take NCOs)<br /><br />4. Good to excellent physical condition, full range of motion, etc. etc.<br /><br />5. Pryor civil service not required.<br /><br />6. Must be a team player and a generalist, (not "gadget good" in just one discipline.) (Eg. A flight systems engineering type who dabbles in geology.)<br /><br />If NASA wants you you will be invited down to Houston for a physical and an orientation. Takes the better part of a week to get probed, poked, and properly tested. <br /><br />"A" list (my term) candidates will get invited back again for "part deux" at a later date. (As I under stand it 6 mos to a year later.) <br /><br />I recommend getting in touch directly with the Astronaut Office-PAO Officer for the real info on what they recommend/need. (They just love to dispense this kind of stuff!)<br /><br />GO FOR IT! ...and good luck!
