One day while we're preparing to leave California to move east for the Astronaut program, the landlord showed some prospective new tenants though the house we had been living in for eight months. I'm sure that there are a lot of completely reasonable people who would agree with the lady that this is a wild endeavor implemented by foolhardy men. Naturally I think she's wrong. I think it's a sound and necessary venture implemented by thoughtful and sensible men. But there is no use denying that there is an element of risk here, an element we will all want to calculate very finely.
Men study physiology to report on body reactions during flight.
