The Orlan space suit (russian: Орлан, lit=Sea eagle (bird), sea eagle) is a series of semi-rigid one-piece space suit models designed and built by NPP Zvezda. They have been used for spacewalks (EVAs) in the Russian space program, the successor to the Soviet space program, and by space programs of other countries, including NASA. History The first spacewalk using an Orlan suit took place on December 20, 1977, on the Soviet space station Salyut 6, during the Soyuz 26 mission. Yuri Romanenko and Georgi Grechko tested the Orlan-D space suit. The Orlan-DM was used for the first time on August 2, 1985, by the cosmonauts Vladimir Dzhanibekov and Viktor Savinykh of Salyut 7. The Orlan space suits were used for spacewalks on the Salyut stations, but for Mir they were replaced by the Orlan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Space Suit
A space suit or spacesuit is a garment worn to keep a human alive in the harsh environment of outer space, vacuum and temperature extremes. Space suits are often worn inside spacecraft as a safety precaution in case of loss of cabin pressure, and are necessary for extravehicular activity (EVA), work done outside spacecraft. Space suits have been worn for such work in Earth orbit, on the surface of the Moon, and en route back to Earth from the Moon. Modern space suits augment the basic pressure garment with a complex system of equipment and environmental systems designed to keep the wearer comfortable, and to minimize the effort required to bend the limbs, resisting a soft pressure garment's natural tendency to stiffen against the vacuum. A self-contained oxygen supply and environmental control system is frequently employed to allow complete freedom of movement, independent of the spacecraft. Three types of space suits exist for different purposes: IVA (intravehicular activity) ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shenzhou 7
Shenzhou 7 () was the third human spaceflight mission of the Chinese space program. The mission, which included the first Chinese extra-vehicular activity (EVA) carried out by crew members Zhai Zhigang and Liu Boming, marked the commencement of the second phase of the Chinese government's Project 921. The Shenzhou spacecraft carrying the three crew members was launched 25 September 2008, by a Long March 2F (CZ-2F) rocket which lifted off from the Jiuquan Satellite Launch Center at 21:10 CST. The mission lasted three days, after which the craft landed safely in Siziwang Banner in central Inner Mongolia on 28 September 2008, at 17:37 CST. The Shenzhou 7 EVA made the Chinese space program the third to have conducted an EVA. EVAs had previously been conducted by the space programs of the Soviet Union (later Russia) and the United States. Crew The crew for Shenzhou 7 was announced on 17 September 2008. Backup crew Of the back-up crew, only Chen Quan had not previously flown i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Liu Boming (astronaut)
Liu Boming (; born September 17, 1966) is a major general in the Chinese People's Liberation Army Strategic Support Force (PLASSF). A fighter pilot in the PLA Air Force (PLAAF), he was selected into the PLA Astronaut Corps (PLAAC) in 1998. A Shenzhou 7 veteran, he also worked on the Tiangong space station during the Shenzhou 12 mission from June to September 2021. With a combined total of three EVA's performed, he spent some 13 hours walking in space which is currently the record by a Chinese astronaut. Astronaut Corps career Liu, along with Zhai Zhigang and Jing Haipeng, was chosen to be the main crew of Shenzhou 7, with Zhai as commander, on 17 September 2008. On 25 September, at 21:10 CST, they launched into space as China's third human spaceflight mission, and the first Chinese mission ever to have a three-man crew.

Mir Space Station
''Mir'' (russian: Мир, ; ) was a space station that operated in low Earth orbit from 1986 to 2001, operated by the Soviet Union and later by Russia. ''Mir'' was the first modular space station and was assembled in orbit from 1986 to 1996. It had a greater mass than any previous spacecraft. At the time it was the largest artificial satellite in orbit, succeeded by the International Space Station (ISS) after ''Mir'''s orbital decay, orbit decayed. The station served as a microgravity research laboratory in which crews conducted experiments in biology, human biology, physics, astronomy, meteorology, and spacecraft systems with a goal of developing technologies required for permanent occupation of Outer space, space. ''Mir'' was the first continuously inhabited long-term research station in orbit and held the record for the longest continuous human presence in space at 3,644 days, until it was surpassed by the ISS on 23 October 2010. It holds the record for the longes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Salyut 7
Salyut 7 (russian: Салют-7; en, Salute 7) (a.k.a. DOS-6, short for Durable Orbital Station) was a space station in low Earth orbit from April 1982 to February 1991. It was first crewed in May 1982 with two crew via Soyuz T-5, and last visited in June 1986, by Soyuz T-15. Various crew and modules were used over its lifetime, including 12 crewed and 15 uncrewed launches in total. Supporting spacecraft included the Soyuz T, Progress (spacecraft), Progress, and TKS spacecraft. It was part of the Soviet Union, Soviet Salyut programme, and launched on 19 April 1982 on a Proton (rocket), Proton rocket from Baikonur Cosmodrome Site 200, Site 200/40 at the Baikonur Cosmodrome in the Soviet Union. Salyut 7 was part of the transition from monolithic to modular space stations, acting as a testbed for docking of additional modules and expanded station operations.

Umbilical Cord
In placental mammals, the umbilical cord (also called the navel string, birth cord or ''funiculus umbilicalis'') is a conduit between the developing embryo or fetus and the placenta. During prenatal development, the umbilical cord is physiologically and genetically part of the fetus and (in humans) normally contains two arteries (the umbilical arteries) and one vein (the umbilical vein), buried within Wharton's jelly. The umbilical vein supplies the fetus with oxygenated, nutrient-rich blood from the placenta. Conversely, the fetal heart pumps low-oxygen, nutrient-depleted blood through the umbilical arteries back to the placenta. Structure and development The umbilical cord develops from and contains remnants of the yolk sac and allantois. It forms by the fifth week of development, replacing the yolk sac as the source of nutrients for the embryo. The cord is not directly connected to the mother's circulatory system, but instead joins the placenta, which transfers materials t ...

Soviet Moonshot
The Soviet crewed lunar programs were a series of programs pursued by the Soviet Union to land humans on the Moon, in competition with the United States Apollo program. The Soviet government publicly denied participating in such a competition, but secretly pursued two programs in the 1960s: crewed lunar flyby missions using Soyuz 7K-L1 (Zond) spacecraft launched with the Proton-K rocket, and a crewed lunar landing using Soyuz 7K-LOK and LK spacecraft launched with the N1 rocket. Following the dual American successes of the first crewed lunar orbit on 24–25 December 1968 (Apollo 8) and the first Moon landing on July 20, 1969 (Apollo 11), and a series of catastrophic N1 failures, both Soviet programs were eventually brought to an end. The Proton-based Zond program was canceled in 1970, and the N1-L3 program was ''de facto'' terminated in 1974 and officially canceled in 1976. Details of both Soviet programs were kept secret until 1990 when the government allowed them to be pu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
