Tiangong 1
Tiangong-1 () was China's first prototype space station. It orbited Earth from September 2011 to April 2018, serving as both a crewed laboratory and an experimental testbed to demonstrate orbital rendezvous and docking capabilities during its two years of active operational life. Launched uncrewed aboard a Long March 2F launch vehicle on 29 September 2011, it was the first operational component of the Tiangong program, which launched a larger, modular station into orbit in 2021. Tiangong-1 was initially projected to be deorbited in 2013,"China to launch module for future space station" 28 September 2011 Retrieved 10 March 2013 to be replaced over the following decade by the larger ...

Atmospheric Entry
Atmospheric entry (sometimes listed as Vimpact or Ventry) is the movement of an object from outer space into and through the gases of an atmosphere of a planet, dwarf planet, or natural satellite. Atmospheric entry may be ''uncontrolled entry,'' as in the entry of astronomical objects, space debris, or bolides. It may be ''controlled entry'' (or ''reentry'') of a spacecraft that can be navigated or follow a predetermined course. Methods for controlled atmospheric ''entry, descent, and landing'' of spacecraft are collectively termed as ''EDL''. Objects entering an atmosphere experience atmospheric drag, which puts mechanical stress on the object, and aerodynamic heating—caused mostly by compression of the air in front of the object, but also by drag. These forces can cause loss of mass ( ablation) or even complete disintegration of smaller objects, and objects with lower compressive strength can explode. Objects have reentered with speeds ranging from 7.8 km/s for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tiangong-2
Tiangong-2 () was a Chinese space laboratory and part of the Project 921-2 space station program. Tiangong-2 was launched on 15 September 2016. It was deorbited as planned on 19 July 2019. Tiangong-2 was neither designed nor planned to be a permanent orbital station; rather, it was intended as a testbed for key technologies used in the Tiangong station (Chinese large modular space station) of which the first module launched on 29 April 2021 and the remaining modules of which launched in 2022. History The China Manned Space Engineering Office published a brief description of Tiangong-2 and its successor Tiangong-3 in 2008, indicating that at least two crewed spaceships would be launched to dock with Tiangong-2. Tiangong-2 was originally expected to be launched by the China National Space Agency (CNSA) by 2015 to replace the prototype module Tiangong-1, which was launched in September 2011. In March 2011, Chinese officials stated that Tiangong-2 was scheduled to be la ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shenzhou 8
Shenzhou 8 () was an uncrewed flight of China's Shenzhou program, launched on 31 October 2011 UTC, or 1 November 2011 in China, by a Long March 2F rocket which lifted off from the Jiuquan Satellite Launch Center. The Shenzhou 8 spacecraft was automatically docked with the Tiangong-1 space module (launched on 29 September 2011) on 3 November 2011 and again on 14 November 2011. This uncrewed docking – China's first – was followed in 2012 with the crewed Shenzhou 9 mission, which performed a crewed docking (also China's first) with the Tiangong-1 module. Only the Soviet Union (Russia), Japan and the European Space Agency (ESA) had achieved automatic rendezvous and docking prior to China's accomplishment. History On 29 September 2008, Zhang Jianqi (), vice director of China crewed space engineering, announced in an interview of China Central Television (CCTV) that Tiangong-1, an 8-ton "target vehicle", would be launched in 2010 (now 2011), and that Shenzhou 8, Shen ...

Tiangong-3
Tiangong-3 () was a proposed Chinese space station, part of the Tiangong program. The China National Space Agency (CNSA) was originally expected to launch Tiangong-3 around 2015, following the launch of the Tiangong-2 test laboratory, originally planned for 2013. The goals for the Tiangong-2 and Tiangong-3 laboratories were merged, and the latter was therefore not ordered. The first module of the third station of the Tiangong program, Tiangong space station, was eventually launched in 2021. Development In 2008, the China Manned Space Engineering Office (CMSEO) published a brief description of Tiangong-2 and Tiangong-3, indicating that several crewed spaceships would be launched in the late 2010s to dock with Tiangong-3. The first Tiangong module, Tiangong-1, was launched in September 2011 and docked with the uncrewed Shenzhou 8 spacecraft in November 2011, marking China's first orbital docking.

China National Space Administration
The China National Space Administration (CNSA) is a government agency of the People's Republic of China headquartered in Haidian District, Haidian, Beijing, responsible for civil space administration and international space cooperation. These responsibilities include organizing or leading foreign exchanges and cooperation in the aerospace field. The CNSA is an administrative agency under the State Administration of Science, Technology and Industry for National Defense. Founded in 1993, CNSA has pioneered a number of achievements in space for China despite its relatively short history, including becoming the first space agency to land on the far side of the Moon with Chang'e 4, bringing material back from the Moon with Chang'e 5 and Chang'e 6, 6, and being the second agency who successfully landed a rover on Mars with Tianwen-1. Tianwen-2 is enroute to explore the co-orbital near-Earth asteroid 469219 Kamoʻoalewa and the active asteroid 311P/PanSTARRS and collecting samples of ...

Pacific Ocean
The Pacific Ocean is the largest and deepest of Earth's five Borders of the oceans, oceanic divisions. It extends from the Arctic Ocean in the north to the Southern Ocean, or, depending on the definition, to Antarctica in the south, and is bounded by the continents of Asia and Australia in the west and the Americas in the east. At in area (as defined with a southern Antarctic border), the Pacific Ocean is the largest division of the World Ocean and the hydrosphere and covers approximately 46% of Earth's water surface and about 32% of the planet's total surface area, larger than its entire land area ().Pacific Ocean .

Telemetry
Telemetry is the in situ collection of measurements or other data at remote points and their automatic transmission to receiving equipment (telecommunication) for monitoring. The word is derived from the Greek roots ''tele'', 'far off', and ''metron'', 'measure'. Systems that need external instructions and data to operate require the counterpart of telemetry: telecommand. Although the term commonly refers to wireless data transfer mechanisms (e.g., using radio, ultrasonic, or infrared systems), it also encompasses data transferred over other media such as a telephone or computer network, optical link or other wired communications like power line carriers. Many modern telemetry systems take advantage of the low cost and ubiquity of GSM networks by using SMS to receive and transmit telemetry data. A ''telemeter'' is a physical device used in telemetry. It consists of a sensor, a transmission path, and a display, recording, or control device. Electronic devices are widely u ...

List Of Female Astronauts
The following is a list of women who have traveled into space, sorted by date of first flight. This list includes Russian cosmonauts, who were the first women in outer space. Valentina Tereshkova became the first woman to go to space in 1963, very early in crewed space exploration, and it would be almost twenty years before another flew (Svetlana Savitskaya). By the end of the 1980s, women in space had become more common. By 2019, roughly 12% of all the space travelers were women. , 105 women had completed spaceflights. History , there has been one female space traveler each from France, Italy, South Korea, Saudi Arabia, and the United Kingdom; two each from Canada and Japan; three from China; six from the Soviet Union/Russia; and 56 from the United States. The time between the first male and first female astronauts varied widely by country.
