Tianzhou 4
Tianzhou 4 () was the fourth mission of the Tianzhou-class uncrewed cargo spacecraft, and the third resupply mission to Tiangong Space Station carrying 5 tons of cargos and 1 ton of propellant. It is the largest load capacity cargo spacecraft that is on active duty. It launched on 9 May 2022, docking successfully with the Tiangong space station at the aft port 6 hours after launch. Like previous Tianzhou missions, the spacecraft launched from the Wenchang Satellite Launch Center in Hainan, China on a Long March 7 rocket. It is a part of the construction of the Tiangong space station, and is the third cargo resupply mission to the already launched Tianhe core module (CCM). Spacecraft The Tianzhou cargo spacecraft has several notable differences with the Tiangong-1 from which it is derived. It has only three segments of solar panels (against 4 for Tiangong), but has 4 maneuvering engines (against 2 for Tiangong). Mission history On May 7, 2022, the combination of the Tian ...

Tiangong Program
The Tiangong program () is China's space program to create a modular space station, comparable to Mir. This program is independent and unconnected to any other international space-active countries. The program is part of the China Manned Space Program that began in 1992. The core module of the Tiangong space station, the '' Tianhe'' ("Harmony of the Heavens") was finally launched on 29 April 2021 marking the start of the Tiangong Space program deployment. China launched its first space laboratory, Tiangong-1, on 29 September 2011. Following Tiangong-1, a more advanced space laboratory complete with cargo spacecraft, dubbed Tiangong-2, was launched on 15 September 2016. The first module of the 12 part new series of Tiangong space station launched on 29 April 2021. The project culminated with the Tiangong space station, which consists of a 22.6-ton core module and cargo transport craft, with two more major research modules launched in 2022.

Solar Panels On Spacecraft
Spacecraft operating in the inner Solar System usually rely on the use of power electronics-managed photovoltaic solar panels to derive electricity from sunlight. Outside the orbit of Jupiter, solar radiation is too weak to produce sufficient power within current solar technology and spacecraft mass limitations, so radioisotope thermoelectric generators (RTGs) are instead used as a power source.NASA JPL Publication: Basics of Space Flight, Chapter 11. Typical Onboard Systems, Electrical Power Supply and Distribution Subsystems, History The first practical silicon-based solar cells were introduced by Russell Shoemaker Ohl, a researcher at Bell Labs in 1940. It was only 1% efficient. In April 25, 1954 in Murray Hill, New Jersey. They demonstrated their solar panel by using it to power a small toy Ferris wheel and a solar powered radio transmitter. They were initially about 6% efficient, but improvements began to raise this number almost immediately. Bell had been interested in t ...

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 Space Station
Tiangong (), officially the ''Tiangong'' space station (), is a permanently crewed space station constructed by China and operated by China Manned Space Agency. Tiangong is a modular design, with modules docked together while in low Earth orbit, between above the surface. It is China's first long-term space station, part of the Tiangong program and the core of the "Third Step" of the China Manned Space Program; it has a pressurised volume of 340 m3 (12,000 cu ft), slightly over one third the size of the International Space Station. The space station aims to provide opportunities for space-based experiments and a platform for building capacity for scientific and technological innovation. The construction of the station is based on the experience gained from its precursors, Tiangong-1 and Tiangong-2. The first module, the ''Tianhe core module, Tianhe'' ("Harmony of the Heavens") core module, was launched on 29 April 2021. This was followed by multiple crewed and uncrewed miss ...

Spacecraft
A spacecraft is a vehicle that is designed spaceflight, to fly and operate in outer space. Spacecraft are used for a variety of purposes, including Telecommunications, communications, Earth observation satellite, Earth observation, Weather satellite, meteorology, navigation, space colonization, Planetary science, planetary exploration, and Space transport, transportation of Human spaceflight, humans and cargo spacecraft, cargo. All spacecraft except single-stage-to-orbit vehicles cannot get into space on their own, and require a launch vehicle (carrier rocket). On a sub-orbital spaceflight, a space vehicle enters space and then returns to the surface without having gained sufficient energy or velocity to make a full Geocentric orbit, Earth orbit. For orbital spaceflights, spacecraft enter closed orbits around the Earth or around other Astronomical object, celestial bodies. Spacecraft used for human spaceflight carry people on board as crew or passengers from start or on orbit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Shenzhou 14
Shenzhou 14 () was a Chinese spaceflight to the Tiangong space station, launched on 5 June 2022. It carried three People's Liberation Army Astronaut Corps (PLAAC) Astronaut#Taikonaut, taikonauts on board a Shenzhou (spacecraft), Shenzhou spacecraft. The mission was the ninth crewed Chinese spaceflight and the fourteenth flight overall of the China Manned Space Program, Shenzhou program. Background Shenzhou 14 was the third spaceflight to the Tiangong space station, and the second with a planned duration of six months (180 days). Shenzhou 14 would also mark the beginning of Tiangong being permanently inhabited, with Shenzhou 14 departing after the arrival of Shenzhou 15, and the same being done on subsequent expeditions. Prior to launch, the Shenzhou 14 spacecraft was maintained in a state of near-readiness if needed as a lifeboat for the Shenzhou 13 crew. The crew of Shenzhou 14 was announced on 4 June 2022.

Shenzhou 13
Shenzhou 13 () was a Chinese spaceflight to the Tiangong space station, launched on 15 October 2021. It carried three People's Liberation Army Astronaut Corps (PLAAC) taikonauts on board a Shenzhou spacecraft. The mission was the eighth crewed Chinese spaceflight and the thirteenth flight overall of the Shenzhou program. Background Shenzhou 13 was the second spaceflight to the Tiangong space station (at the time consisting only of the ''Tianhe'' core module), and the first with a planned duration of six months (180 days). Following Shenzhou 13, six months would become the standard orbital duration for subsequent Shenzhou missions. For Shenzhou 13, the China Academy of Space Technology developed a new method of radial docking of the spacecraft to the bottom of Tiangong's ''Tianhe'' core module, differing from the front and rear docking method used previously by Shenzhou 12 and the Tianzhou cargo missions.
