Tianzhou 5
Tianzhou 5 () is the fifth mission of the Tianzhou-class unmanned cargo spacecraft, and the fourth resupply mission to the Tiangong Space Station. Like previous Tianzhou missions, the spacecraft was launched from the Wenchang Satellite Launch Center in Hainan, China on a Long March 7 rocket. It was successfully placed into orbit on 12 November and docked to the Tiangong space station on the same day. The rendezvous and docking process lasted 2 hours and 7 minutes, setting a world record for the fastest rendezvous and docking between a spacecraft and a space station, surpassing Soyuz MS-17's 3 hours and 3 minutes. 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 A solar cell panel, solar electric panel, photo-voltaic (PV) module, PV panel or solar panel is an assembly of photovoltaic solar cells mounted in a (usually rectangular) frame, and a neatly organis ...

Tianzhou (spacecraft)
The Tianzhou () is a Chinese automated cargo spacecraft developed from China's first prototype space station Tiangong-1 to resupply its modular space station. It was first launched (Tianzhou 1) on the Long March 7 rocket from Wenchang on April 20, 2017 and demonstrated autonomous propellant transfer (space refueling). The first version of Tianzhou has a mass of 12,910 kg and can carry 6,500 kg of cargo. Function Based on the Tiangong-1 space station, the Tianzhou functions as the main automated cargo spacecraft for the Tiangong space station. It has pressurized, semi-pressurized and unpressurized cargo capabilities, and is able to transport airtight cargo, large extravehicular payloads and experiment platforms. It was first launched on the new Long March 7 rocket from Wenchang on April 20, 2017. Name The China Manned Space Engineering Office opened a consultation for the naming of the prospective cargo ship on April 25, 2011. By May 20, it had received more than 50,000 sugges ...

Shenzhou 15
Shenzhou 15 () is a Chinese spaceflight that launched on 29 November 2022 at 15:08 UTC. The flight marked the tenth crewed Chinese spaceflight and the fifteenth flight of the Shenzhou program. The spacecraft carried three People's Liberation Army Astronaut Corps (PLAAC) taikonauts on the fourth flight to the ''Tianhe'' core module, the first module of the Tiangong space station. The launch of the three-person crew with a Long March 2F launch vehicle took place from the Jiuquan Satellite Launch Center. Background The spaceflight is the third Chinese mission set to last six months (180 days). The flight marked the fourth crewed mission to dock with the Tiangong space station before the end of 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 Bell Labs in April 1954. They were initially about 6% efficient, but improvements began to raise this number almost immediately. Bell had been interested in the idea as a system to provide power at remote telephone repeater stations, but the cost of the devices was far too high to be practical in this role. Aside from small experimental kits and uses, the cells remained largely unus ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cargo Spacecraft
Cargo spacecraft are robotic spacecraft that are designed to carry cargo, possibly to support space stations' operation by transporting food, propellant and other supplies. This is different from a space probes, space probe, whose missions are to conduct scientific investigations. Automated cargo spacecraft have been used since 1978 and have serviced Salyut 6, Salyut 7, Mir, the International Space Station and Tiangong program, Tiangong space station. Spacecraft Current spacecraft * the Russian Progress spacecraft—developed by Russian Federal Space Agency * the American SpaceX Dragon 2, Dragon 2 spacecraft—developed under contract from NASA by SpaceX, a private spaceflight company, the only reusable cargo spacecraft * the American Cygnus spacecraft—developed under contract from NASA by Northrop Grumman Innovation Systems, a private spaceflight company * the Chinese Tianzhou (spacecraft), Tianzhou spacecraft—developed by China Aerospace Science and Technology Corporation ...

Soyuz MS-17
Soyuz MS-17 was a Soyuz spaceflight that was launched on 14 October 2020. It transported three crew members of the Expedition 63/ 64 crew to the International Space Station. Soyuz MS-17 was the 145th crewed flight of a Soyuz spacecraft. The crew consisted of a Russian commander and a Russian and American flight engineer. The mission marked the first use of a new "ultrafast" two-orbit rendezvous flight plan with the Soyuz, which saw Soyuz MS-17 arrive at the ISS within approximately three hours after the launch. On 19 March 2021, the crew of Soyuz MS-17 boarded their spacecraft to relocate it from ''Rassvet'' to ''Poisk'' to make way for the arrival and docking of the Soyuz MS-18 spacecraft, which launched on 9 April 2021 carrying cosmonauts Oleg Novitsky, Pyotr Dubrov and the astronaut of NASA, Mark T. Vande Hei to the ISS ahead of a six-month stay. The two spacecraft had a nine-day handover period before Soyuz MS-17 departed. This is necessary to avoid de-crewing the Russ ...

Spacecraft
A spacecraft is a vehicle or machine designed to fly in outer space. A type of artificial satellite, spacecraft are used for a variety of purposes, including communications, Earth observation, meteorology, navigation, space colonization, planetary exploration, and transportation of humans and 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 Earth orbit. For orbital spaceflights, spacecraft enter closed orbits around the Earth or around other celestial bodies. Spacecraft used for human spaceflight carry people on board as crew or passengers from start or on orbit (space stations) only, whereas those used for robotic space missions operate either autonomously or telerobotically. Robotic spacecraft used to support scientific re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
