Tianzhou 2
Tianzhou 2 () was a mission of the Tianzhou (spacecraft), Tianzhou-class uncrewed cargo spacecraft. The launch took place at 29 May 2021, 12:55:29 Coordinated Universal Time, UTC. The spacecraft successfully docked with the Tiangong space station later on the same day. Mission profile Tianzhou 2 is a part of the construction of the Tiangong space station, and is the first cargo resupply mission to the already launched Tianhe core module, ''Tianhe'' core module (CCM). The spacecraft remained docked to the aft docking port of Tianhe until the concurrent crewed mission Shenzhou 12 deorbited in September, after which it was moved to the forward docking port. It will then conduct propellant transfer testing with Tianhe and serve as a test unit for Tianhe's robotic arm to manipulate modules as part of space station construction. It undocked on 27 March 2022, did a 2-hour fast rendezvous on 30 March 2022 and burned up in the Earth's atmosphere as planned on re-entry on 31 March 2022 ...

Tianhe Core Module
''Tianhe'' (), officially the ''Tianhe'' core module (), is the first module to launch of the Tiangong space station. It was launched into orbit on 29 April 2021, as the first launch of the final phase of Tiangong program, part of the China Manned Space Program ( Project 921). ''Tianhe'' follows the earlier projects Salyut, Skylab, Mir, International Space Station, Tiangong-1 and Tiangong-2 space stations. It is the first module of a third-generation Chinese modular space station. Other examples of modular station projects include the Soviet/Russian Mir and the International Space Station. Operations will be controlled from the Beijing Aerospace Flight Control Center. In 2018, a fullscale mockup of ''Tianhe'' was publicly presented at China International Aviation & Aerospace Exhibition in Zhuhai.

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 ...

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] |

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.

Low Earth Orbit
A low Earth orbit (LEO) is an geocentric orbit, orbit around Earth with a orbital period, period of 128 minutes or less (making at least 11.25 orbits per day) and an orbital eccentricity, eccentricity less than 0.25. Most of the artificial objects in outer space are in LEO, peaking in number at an altitude around , while the farthest in LEO, before medium Earth orbit (MEO), have an altitude of 2,000 km, about one-third of the Earth radius, radius of Earth and near the beginning of the Van Allen radiation belt#Inner belt, inner Van Allen radiation belt. The term ''LEO region'' is used for the area of space below an altitude of (about one-third of Earth's radius). Objects in orbits that pass through this zone, even if they have an apogee further out or are sub-orbital spaceflight, sub-orbital, are carefully tracked since they present a collision risk to the many LEO satellites. No human spaceflights other than the lunar missions of the Apollo program (1968-1972) have gone beyond L ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...
