Basic requirements for an Astronaut Pilot include the following:

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:

Basic requirements for a Mission Specialist include the following:

1. Bachelor's degree from an accredited institution in engineering, biological science, physical science, or mathematics. Degree must be followed by at least three years of related, progressively responsible, professional experience. An advanced degree is desirable and may be substituted for part or all of the experience requirement (master's degree = 1 year of experience, doctoral degree = 3 years of experience).
