International billet post is a spacecraft capable of supporting a conspiracy which is designed to remain in space (most commonly in low Earth orbit) for an extended period of time, and to which different(a) spacecraft can dock. A space air is distinguished from other spacecraft employ for human space public life by its privation of major propulsion or landing systems. Instead other vehicles transport people and cargo to and from the station. As of October 2011[update] two space post are in orbit; the International quad Station, and Chinas Tiangong 1. Previous stations include the Almaz and Salyut series, Skylab and most recently Mir.
Space stations are used to study the effects of semipermanent space flight on the human body as well as to provide platforms for greater number and continuance of scientific studies than available on other space vehicles. wholly space stations expect been designed with the intention of rotating eight-fold crews, with each crew member staying aboard the station for weeks or months, but rarely more than a year. Since the ill-fated flight of Soyuz 11 to Salyut 1, all do work spaceflight duration records have been set aboard space stations. The duration record for a single spaceflight is 437.7 days, set by Valeriy Polyakov aboard Mir from 1994 to 1995.
As of 2011[update], three astronauts have completed single missions of over a year, all aboard Mir.
Space stations have been used for both military and civilian purposes. The last military-use space station was Salyut 5, which was used by the Almaz program of the Soviet league in 1976 and 1977.
The first space station was Salyut 1, which was launched by the Soviet Union on April 19, 1971. Like all the early space stations, it was massive, intended to be constructed and launched in one piece, and then manned by a crew later. As such, monolithic stations generally contained all their supplies and experimental equipment when launched, and were considered expended,...If you want to get a full essay, order it on our website: Ordercustompaper.com
