A space station, likewise called an orbital terminal or a periodic space station, is a spacecraft efficient in supporting a workers, which is created to continue to be in space (most generally as a fabricated satellite in low
Planet orbit) for a prolonged time frame as well as for other spacecraft to dock. A space station is differentiated from various other spacecraft used for human spaceflight by absence of major propulsion or landing systems.
Instead, various other automobiles deliver individuals and payload to and from the station. Since
September 2014 two space stations are in orbit: the
International Space Station, which is permanently manned, and
China's Tiangong-1 (which efficiently released on
September 29,
2011), which is unmanned most of the time. Previous terminals consist of the
Almaz as well as
Salyut collection, Skylab and most just recently Mir.
Today's space stations are research systems, made use of to examine the results of long-lasting room trip on the human body as well as to supply platforms for majority and length of clinical studies than readily available on other room automobiles. All space stations to date have actually been made with the intention of turning multiple staffs, with each staff participant remaining aboard the station for weeks or months, but rarely greater than a year. Given that the unfortunate air travel of
Soyuz 11 to Salyut 1, all manned spaceflight duration records have been set aboard space stations. The period record for a solitary spaceflight is 437.
7 days, established by
Valeriy Polyakov aboard Mir from
1994 to
1995. Since
2013, three astronauts have actually finished solitary objectives of over a year, all aboard Mir.
The first space station was Salyut 1, which was introduced by the
Soviet Union on
April 19,
1971. Like all the early space stations, it was "monolithic", intended to be created and released intact, and afterwards manned by a team later on. As such, monolithic terminals typically contained all their materials and also experimental tools when launched, as well as were thought about "used up", and then abandoned, when these were used up.
The earlier
Soviet stations were all marked "Salyut", yet among these there were two distinctive types: civilian and armed forces. The armed forces terminals, Salyut 2, Salyut 3, and also Salyut 5, were likewise known as Almaz stations.
