The beginnings of space medicine.

The beginnings of space medicine are those of aviation medicine and involved, among many pioneers, Dr. Harry G. Armstrong and the Aeromedical Laboratory. Space Medicine has advanced in a short 23 years from arguments about man being capable of survival in space through animal and manned flights to flight durations of 6 months. The public and private arguments about man's capability to survive and work in space and the early decisions about flight duration and safety are chronicled from a personal point of view.
