Tiangong-1

Tiangong-1 (Chinese: 天宫一号; pinyin: Tiāngōng yīhào; literally: "Heavenly Palace 1") is China's first space station, serving as both a manned laboratory and an experimental testbed to demonstrate orbital rendezvous and docking capabilities. Launched unmanned aboard a Long March 2F/G rocket on 29 September 2011, it is the first operational component of the Tiangong program, which aims to place a larger, modular station into orbit by 2023.As of September 2011, Tiangong-1 was projected to be deorbited in 2013, and replaced over the following decade by the larger Tiangong-2 and Tiangong-3 modules. However, Tiangong-1 remains in orbit as of 2015.

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.

China

China, officially the People's Republic of China (PRC), is a sovereign state in East Asia. It is the world's most populous country, with a population of over 1.35 billion. The PRC is a one-party state governed by the Communist Party, with its seat of government in the capital city of Beijing. It exercises jurisdiction over 22 provinces; five autonomous regions; four direct-controlled municipalities (Beijing, Tianjin, Shanghai and Chongqing); two mostly self-governing special administrative regions (Hong Kong and Macau); and claims sovereignty over Taiwan.

Covering approximately 9.6 million square kilometers, China is the world's second-largest country by land area, and either the third or fourth-largest by total area, depending on the method of measurement. China's landscape is vast and diverse, ranging from forest steppes and the Gobi and Taklamakan deserts in the arid north to subtropical forests in the wetter south. The Himalaya, Karakoram, Pamir and Tian Shan mountain ranges separate China from South and Central Asia. The Yangtze and Yellow Rivers, the third- and sixth-longest in the world, run from the Tibetan Plateau to the densely populated eastern seaboard. China's coastline along the Pacific Ocean is 14,500 kilometres (9,000 mi) long, and is bounded by the Bohai, Yellow, East and South China Seas.

Space station

A space station, also known as an orbital station or an orbital space station, is a spacecraft capable of supporting a crew, which is designed to remain in space (most commonly as an artificial satellite in low Earth orbit) for an extended period of time and for other spacecraft to dock. A space station is distinguished from other spacecraft used for human spaceflight by lack of major propulsion or landing systems. Instead, other vehicles transport people and cargo to and from the station. As of September 2014 two space stations are in orbit: the International Space Station, which is permanently manned, and China's Tiangong-1 (which successfully launched on September 29, 2011), which is unmanned most of the time. Previous stations include the Almaz and Salyut series, Skylab and most recently Mir.

Today's space stations are research platforms, used to study the effects of long-term space flight on the human body as well as to provide platforms for greater number and length of scientific studies than available on other space vehicles. Each crew member staying aboard the station for weeks or months, but rarely more than a year. Most of the time crew remain at station but its not necessary that crew should have to be stay at station. Since the ill-fated flight of Soyuz 11 to Salyut 1, all manned 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 2013, three astronauts have completed single missions of over a year, all aboard Mir.

Shenzhou 9

Shenzhou 9 was a manned spacecraft flight of China's Shenzhou program, launched at 18:37:24 CST (10:37:24 UTC), 16 June 2012. Shenzhou 9 was the second spacecraft and first manned spacecraft to dock with the Tiangong 1 space station, which took place on 18 June. The Shenzhou 9 spacecraft landed at 10:01:16 CST (02:01:16 UTC) on 29 June in Inner Mongolia Autonomous Region. The mission's crew included the first Chinese female astronaut, Liu Yang. The next planned mission was Shenzhou 10, which launched on 11 June 2013.

History

On 12 March 2012, it was announced that the initial crew selection roster for the mission included female astronauts. The crew were unveiled to the press on 15 June. China's first female astronaut would be Liu Yang. Liu was selected ahead of her fellow female astronaut prospect Wang Yaping. This mission also featured the first repeat astronaut, Jing Haipeng, the commander of the mission. Shenzhou 9 was the 9th flight in China's Shenzhou program and the fourth manned spaceflight. The mission's launch was 49 years to the day after that of the first woman in space, cosmonaut Valentina Tereshkova.

Tiangong program

Tiangong (Chinese: 天宫; pinyin: Tiāngōng; literally: "Heavenly Palace") is a space station program of the People's Republic of China, with the goal of creating a third generation space station, comparable to Mir. This program is autonomous and unconnected to any other international space-active countries. The program began in 1992 as Project 921-2. As of January 2013, China moved forward on a large multiphase construction program that will lead to a large space station around 2020.

China launched its first space laboratory, Tiangong 1, on September 29, 2011. Following Tiangong 1, a more advanced space laboratory complete with cargo ship, dubbed Tiangong 2, will be built. Tiangong 3 will continue to develop these technologies. The project will culminate with a large orbital station, which will consist of a 20-ton core module, 2 smaller research modules, and cargo transport craft. It will support three astronauts for long-term habitation and is scheduled to be completed just as the International Space Station is currently scheduled to be retired.
