From 500 candidates having the required jet aircraft flight experience and engineering training as well as height below 5 feet 11 inches, 7 military men became the Nation's first astronauts. The second and third groups chosen included civilians who had extensive flying experience. By 1964, requirements had changed and emphasis was placed on academic qualifications; in 1965, 6 scientist astronauts were selected from a group of 400 applicants who had a doctorate or equivalent experience in the natural sciences, medicine, or engineering. The group named in 1978 was the first of Space Shuttle flight crews and was composed of 15 pilots and 20 mission specialists; 6 of the 35 were women and 4 were members of minorities. Since then, 5 additional groups have been selected with an even mix of pilots and mission specialists. In total, 195 astronauts have been selected in the 13 groups from 1959 through 1990; there are 97 astronauts currently in the program; 78 have retired, resigned or been reassigned; and 20 are deceased. Payload specialists are career scientists or engineers selected by their employer or country for their expertise in conducting a specific experiment or commercial venture on a Space Shuttle mission. Their names are not included in the Astronaut Fact Book. NASA accepts applications for the Astronaut Candidate Program on a continuing basis and selects candidates as needed.
