Low Earth Orbit

Type: 

Government

Description: 

The International Space Station (ISS) is a space station, or a habitable artificial satellite, in low Earth orbit. Its first component was launched into orbit in 1998, with the first long-term residents arriving in November 2000. It has been inhabited continuously since that date. The last pressurised module was fitted in 2011, and an experimental inflatable space habitat was added in 2016. The station is expected to operate until 2030. Development and assembly of the station continues, with several new elements scheduled for launch in 2019. The ISS is the largest human-made body in low Earth orbit and can often be seen with the naked eye from Earth. The ISS consists of pressurised habitation modules, structural trusses, solar arrays, radiators, docking ports, experiment bays and robotic arms. ISS components have been launched by Russian Proton and Soyuz rockets, and American Space Shuttles.

Description: 

Mir was a space station that operated in low Earth orbit from 1986 to 2001, operated by the Soviet Union and later by Russia. Mir was the first modular space station and was assembled in orbit from 1986 to 1996. The station served as a microgravity research laboratory in which crews conducted experiments in biology, human biology, physics, astronomy, meteorology and spacecraft systems with a goal of developing technologies required for permanent occupation of space.

Description: 

Skylab was a United States space station launched and operated by NASA, and occupied for about 24 weeks between May 1973 and February 1974 – the only space station the U.S. has operated exclusively. In 1979 it fell back to Earth amid huge worldwide media attention. Skylab included a workshop, a solar observatory, and other systems necessary for crew survival and scientific experiments. It was launched unmanned by a modified Saturn V rocket, with a weight of 170,000 pounds (77,000 kg). Lifting Skylab into low earth orbit was the final mission and launch of a Saturn V rocket (famous for carrying the manned Moon landing missions). Three missions delivered three-astronaut crews in the Apollo command and service module (Apollo CSM), launched by the smaller Saturn IB rocket. For the final two manned missions to Skylab, a backup Apollo CSM/Saturn IB was assembled and made ready in case an in-orbit rescue mission was needed, but this backup vehicle was never flown.

Description: 

Tiangong-1 (Chinese: 天宫一号; pinyin: Tiāngōng yīhào; literally: "Heavenly Palace 1" or "Celestial Palace 1") was China's first prototype space station. It orbited Earth from September 2011 to April 2018, serving as both a manned laboratory and an experimental testbed to demonstrate orbital rendezvous and docking capabilities during its two years of active operational life. Tiangong-1 was visited by a series of Shenzhou spacecraft during its two-year operational lifetime. The first of these, the unmanned Shenzhou 8, successfully docked with the module in November 2011, while the manned Shenzhou 9 mission docked in June 2012. A third and final mission to Tiangong-1, the manned Shenzhou 10, docked in June 2013. The manned missions to Tiangong-1 were notable for including China's first female astronauts, Liu Yang and Wang Yaping. On 21 March 2016, after a lifespan extended by two years, the China Manned Space Engineering Office announced that Tiangong-1 had officially ended its service. They went on to state that the telemetry link with Tiangong-1 had been lost. A couple of months later, amateur satellite trackers watching Tiangong-1 found that China's space agency had lost control of the station. In September, after conceding they had lost control over the station, officials speculated that the station would re-enter and burn up in the atmosphere late in 2017. According to the China Manned Space Engineering Office, Tiangong-1 started reentry over the southern Pacific Ocean, northwest of Tahiti, on 2 April 2018 at 00:15 UTC.

Description: 

Tiangong-2 (Chinese: 天宫二号; pinyin: Tiāngōng èrhào; literally: "Celestial Palace 2") is a Chinese space laboratory and part of the Project 921-2 space station program. Tiangong-2 was launched on 15 September 2016. Tiangong-2 is neither designed nor planned to be a permanent orbital station; rather, it is intended as a testbed for key technologies that will be used in the Chinese large modular space station, which is planned for launch between 2019 and 2022.

Description: 

Salyut 1 (DOS-1) was the first space station of any kind, launched into low Earth orbit by the Soviet Union on April 19, 1971. The Salyut program followed this with five more successful launches out of seven more stations. The final module of the program, Zvezda (DOS-8) became the core of the Russian segment of the International Space Station and remains in orbit.

Description: 

Salyut 2 (OPS-1) (Russian: Салют-2 meaning Salute 2) was a Soviet space station which was launched in 1973 as part of the Salyut programme. It was the first Almaz military space station to fly. Within two weeks of its launch, the station had lost attitude control and depressurised, leaving it unusable. Its orbit decayed and it re-entered the atmosphere on 28 May 1973, without any crews having visited it.

Description: 

Salyut 3 (Russian: Салют-3; English: Salute 3; also known as OPS-2 or Almaz 2) was a Soviet space station launched on 25 June 1974. It was the second Almaz military space station, and the first such station to be launched successfully. It was included in the Salyut program to disguise its true military nature. Due to the military nature of the station, the Soviet Union was reluctant to release information about its design, and about the missions relating to the station. It attained an altitude of 219 to 270 km on launch and NASA reported its final orbital altitude was 268 to 272 km. Only one of the three intended crews successfully boarded and manned the station, brought by Soyuz 14; Soyuz 15 attempted to bring a second crew but failed to dock. Although little official information has been released about the station, several sources report that it contained multiple Earth-observation cameras, as well as an on-board gun. The station was deorbited, and re-entered the atmosphere on 24 January 1975. The next space station launched by the Soviet Union was the civilian station Salyut 4; the next military station was Salyut 5, which was the final Almaz space station.

Description: 

Salyut 4 represented the second phase of DOS civilian space station. Although the basic design of Salyut 1 was retained, it switched to three large solar panels mounted on the forward module rather than its predecessor's four small panels on the docking module and engine compartment, presumably to generate more power. It had an interior floor area of 34.8 sq. The pitch of the station was 2 X 59 N, yaw was 2 X 59 N and roll was 2 X 20 N. The electric System produced an average of 2.00 kW of power. It had 2,000 kg of scientific equipment alongside two sets of three solar panels each and was equipped with the Delta Navigation System which was a new autonomous navigation system that calculates orbital elements without assistance from ground. It was powered by KTDU-66 thrusters. Instrumentation

Description: 

Salyut 5, also known as OPS-3, was a Soviet space station. Launched in 1976 as part of the Salyut programme, it was the third and last Almaz space station to be launched for the Soviet military. Two Soyuz missions visited the station, each manned by two cosmonauts. A third Soyuz mission attempted to visit the station, but failed to dock, whilst a fourth mission was planned but never launched.
