In 1984, U.S. President Ronald Reagan announced the beginning of works on creation of an American space station.
In 1988 the station was named “Freedom” (“Freedom”). At that time it was a joint project of USA, ESA, Canada and Japan. Planned managed large station modules which will be delivered on orbit by space shuttles. But by the beginning of 1990-ies it became clear that the cost of developing the project is too large and only international cooperation will allow to create such a station. The USSR, already had experience of creation and injection into orbit, orbital stations “Salyut” and “Mir” space station, planned in the early 1990s, the creation of the station “Mir-2”, but due to economic difficulties, the project was suspended.
17 June 1992 the U.S. and Russia signed an agreement on cooperation in space research. In accordance with the Russian space Agency and NASA have developed a joint program “Mir — Shuttle”. This programme provided for the safety of American ships reusable “space Shuttle” to the Russian space station Mir, the inclusion of a Russian cosmonaut in the crew of the American Shuttle and American astronauts in the crew of the Soyuz spacecraft and the Mir station.

SPACECRAFT ( SC ) is a technical device used to perform a variety of tasks in space. as well as conducting research and other works on the surface of various celestial bodies. Means of delivery of spacecraft into orbit serve as launch vehicles or aircraft .
Spacecraft, one of the main objectives of which is to transport people or equipment in the upper part of the earth’s atmosphere — the so-called near space. also called “Space aircraft” ( CLA ).
The use of spacecraft to determine their separation in the following groups:
suborbital SPACECRAFT ;
earth orbital SPACECRAFT . moving on geocentric orbits of artificial satellites ;
interplanetary (expeditionary) SC ;
napolnenie KA . Continue reading
