Unlike the annual checkup from a primary physician, this long-duration spaceflight physical requires 20/20 vision (or the ability to correct vision to that level), blood pressure lower than 140/90,. However, NASA does say that an advanced degree is desirable since the quality of academic preparation is important., P's do not get degrees when it comes to becoming an astronaut.
