NASA missions
The most important part of NASA's activities are its missions; they can be divided into manned and unmanned. The latter can be either independent, carrying scientific equipment, or supportive, testing equipment for manned flights. In the beginning, NASA’s missions focused on the spacerace with the Soviet Union, which won the first round, but later USA took the initiative and won the final race to the Moon. The unmanned missions have until now explored most of the solar system. They have also brought telescopes for deep space exploration into orbit around the Earth together with satellites for studying Earth itself.
• Manned missions
The rocket planes experiments started by NACA was taken a step further by NASA which used them as support for spaceflights, the first of which was one-manned and launched by military rockets. When the attention turned to reaching the Moon, the solution chosen was complicated but also the most economical. Supportive projects, both manned and unmanned were introduced and bigger rockets together with spacecraft and moonlander developed. The Moon landing and end of the space race meant a reduction of NASA’s activities. Space stations of a more or less permanent nature, suggested already during the spacerace, were built and an international cooperation was introduced in an attempt to both bring nations together and at the same time share the high costs of space missions. In all, more than 100 manned missions have been made by NASA since 1958.
