Alphabetical list of astronauts and cosmonauts

Gennadi Mikhailovich Manakov is a former cosmonaut who commanded two Soyuz flights. He was selected on 2 September 1985 and flew as Commander on Soyuz TM-10 and Soyuz TM-16, retiring on 20 December 1996.
John Howard Casper is an American astronaut and United States Air Force pilot.

Cosmonaut and astronaut are synonyms, that is, theoretically we can use them interchangeably, but traditionally we call people launched into space by the Americans astronauts and by the Russians cosmonauts, regardless of what nationalities they were. That is, Americans, Canadians, Japanese, Italians, French and Germans flying with Americans are astronauts. In contrast, General Hermaszewski, the only (so far) Pole in Space, is called a cosmonaut because he flew as part of the Soviet space program.
