Manned Spacecraft - Space Stations

apollo successful development

Since the early 1970s, both the Soviet Union and the United States have sought to develop orbiting space stations. The emphasis in each nation has, however, been somewhat different.

The development of a successful space station requires two major feats: the construction of a habitat in space in which humans can live and work for long periods of time (months or years), and the development of a ferry system by which astronauts and materials can be transported from Earth to the space station and back. The Soviets have focused on the first of these two features and the Americans on the second.
