It must be annoying or disappointing for NASA engineers, spending so much time and effort on sending other people into space... Something to think about.
Sadly, in this world, we all can't be astronauts, in fact few of us meet the requirements. Nasa says that if you want to be a commander or pilot astronaut you need to:
1. Bachelor's degree from an accredited institution in engineering, biological science, physical science, or mathematics. An advanced degree is desirable. Quality of academic preparation is important.
2. At least 1,000 hours pilot-in-command time in jet aircraft. Flight test experience is highly desirable.
3. Ability to pass a NASA space physical which is similar to a military or civilian flight physical and includes the following specific standards:
• 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 64 and 76 inches.
I'll never be an astronaut, damn my spectacle laden eyes and the fact that I am grossly out of shape, and that I have an English degree. Plus I am sure I get space sick, and I don't think I could poop in diapers.
