Space station

The first mention of anything resembling a space station occurred in Edward Everett Hale's 1868 "The Brick Moon".

[3] The first to give serious, scientifically grounded consideration to space stations were Konstantin Tsiolkovsky and Hermann Oberth about two decades apart in the early 20th century.

[5] In 1951, Wernher von Braun published a concept for a rotating wheel space station in Collier's Weekly, referencing Potočnik's idea.

The hardware developed during the initial Soviet efforts remains in use, with evolved variants comprising a considerable part of the ISS, orbiting today.

Early stations were monolithic designs that were constructed and launched in one piece, generally containing all their supplies and experimental equipment.

This method allows for greater flexibility in operation, as well as removing the need for a single immensely powerful launch vehicle.

The Russian autonomous approach allows the assembly of space stations prior to the launch of crew.

As of 2009, RKK Energia was considering the removal and reuse of some modules of the ROS on the Orbital Piloted Assembly and Experiment Complex after the end of mission is reached for the ISS.

Connections for electrical power, data, propulsion, and cooling fluids are also made at this time, resulting in an integrated block of modules that is not designed for disassembly and must be deorbited as one mass.

[citation needed] According to the China Manned Space Engineering Office, Tiangong-1 reentered over the South Pacific Ocean, northwest of Tahiti, on 2 April 2018 at 00:15 UTC.

[52][53] A space station is a complex vehicle that must incorporate many interrelated subsystems, including structure, electrical power, thermal control, attitude determination and control, orbital navigation and propulsion, automation and robotics, computing and communications, environmental and life support, crew facilities, and crew and cargo transportation.

They are typically made from stainless steel, titanium and high-quality aluminum alloys, with layers of insulation such as Kevlar as a ballistics shield protection.

[55][56] This module, based on NASA research in the 1990s, weighs 1,400 kilograms (3,100 lb) and was transported while compressed before being attached to the ISS by the space station arm and inflated to provide a 16 cubic metres (21 cu yd) volume.

[57][58] The space station environment presents a variety of challenges to human habitability, including short-term problems such as the limited supplies of air, water, and food and the need to manage waste heat, and long-term ones such as weightlessness and relatively high levels of ionizing radiation.

[59] Future space habitats may attempt to address these issues, and could be designed for occupation beyond the weeks or months that current missions typically last.

Possible solutions include the creation of artificial gravity by a rotating structure, the inclusion of radiation shielding, and the development of on-site agricultural ecosystems.

[60] Molds that develop aboard space stations can produce acids that degrade metal, glass, and rubber.

Despite an expanding array of molecular approaches for detecting microorganisms, rapid and robust means of assessing the differential viability of the microbial cells, as a function of phylogenetic lineage, remain elusive.

[63] The last military-use space station was the Soviet Salyut 5, which was launched under the Almaz program and orbited between 1976 and 1977.

Soyuz flight T-15 in March to July 1986 was the first and as of 2016, only spacecraft to visit two different space stations, Mir and Salyut 7.

The Mir space station was in orbit from 1986 to 2001 and was supported and visited by the following spacecraft: Research conducted on the Mir included the first long term space based ESA research project EUROMIR 95 which lasted 179 days and included 35 scientific experiments.

This research follows on from previous experiments such as the Long Duration Exposure Facility, a free flying experimental platform which flew from April 1984 until January 1990.

[111][112] On the International Space Station, guests sometimes pay $50 million to spend the week living as an astronaut.
