1. A bachelor's degree in engineering, biological science, physical science, computer science or mathematics.
2. At least three years of related professional experience obtained after degree completion OR at least 1,000 hours pilot-in-command time on jet aircraft.
3. The ability to pass the NASA long-duration astronaut physical. Distant and near visual acuity must be correctable to 20/20 for each eye. The use of glasses is acceptable.
4. Astronaut candidates must also have skills in leadership, teamwork and communications.
Checking all the boxes on that list isn't particularly hard to do. However you aren't competing with the list.
You are competing with a 29 year old Rhodes Scholar with a PhD in Chemistry, who runs Ultramarathons, ran a 40 person volunteer organization in Kenya during her gap year, and manages a 200 person 50 Million dollar research lab on pluripotent stem cells at Oxford.
Now just change out anything there with whatever would be relevant for your line of work, and thats who you are competing with - give or take.
