Soyuz 25
Soyuz 25 (russian: Союз 25, ''Union 25'') was an October, 1977, Soviet crewed space flight, the first to the new Salyut 6 space station, which had been launched 10 days earlier. However, the mission was aborted when cosmonauts Vladimir Kovalyonok and Valery Ryumin failed to engage the docking latches of the station despite five attempts. Lacking sufficient fuel to attempt a dock at the other end of the station and with battery power for only two days, they returned to Earth.The mission report is available here: http://www.spacefacts.de/mission/english/soyuz-25.htm The failure led to a new rule whereby every crew had to have at least one person aboard who had previously flown in space. Crew Backup crew Mission highlights Soyuz 25 was launched on 9 October 1977 with a crew of two cosmonauts to dock with the orbiting Salyut 6 space station, which had been launched 10 days earlier, on 29 September. The crew were to stay on board for about 90 days, which would break the Soviet ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Soyuz 7K-T
The second generation of the Soyuz spacecraft, the ''Soyuz 7K-T'', comprised Soyuz 12 through Soyuz 40 (1973-1981). In the wake of the Soyuz 11 tragedy, the spacecraft was redesigned to accommodate two cosmonauts who would wear pressure suits at all times during launch, docking, undocking, and reentry. The place of the third cosmonaut was taken by extra life-support systems. Finally, the 7K-T, being intended purely as a space station ferry, had no solar panels, instead sporting two large whip antennas in their place. As a result, it relied on batteries which only provided enough power for two days of standalone flight. The idea was that the Soyuz would recharge while docked with a Salyut space station, but in the event of a docking or other mission failure (which ended up happening on several occasions), the crew was forced to power off everything except communications and life support systems until they could reenter. Two test flights of the 7K-T were conducted prior to comm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Yuri Romanenko
Yuri Viktorovich Romanenko (russian: Ю́рий Ви́кторович Романе́нко; born 1 August 1944) is a former Soviet cosmonaut, twice Hero of the Soviet Union (March 16, 1978 and September 26, 1980). Over his career, Yuri Romanenko spent a total of 430 days 20 hours 21 minutes 30 seconds in space and 18 hours in space walks. In 1987 he was a resident of the Mir space station, launching on Soyuz TM-2 and landing aboard Soyuz TM-3. He remained on Mir for 326 days; that was the longest stay in space at that time. His son, Roman Romanenko is also a cosmonaut, and has become the third second-generation space traveler on Soyuz TMA-15 in May 2009. Early life Yuri Romanenko was born on August 1, 1944, in Koltubanovskiy village in Orenburg Oblast, Soviet Union. His father was a senior commander on military ships, and mother was a combat medic. His family later moved to Kaliningrad, where he graduated from a secondary school in 1961. His hobbies in school included building ...

Soyuz TM-19
Soyuz TM-19 was a crewed Soyuz spaceflight to Mir. It launched on 1 July 1994, at 12:24:50 UTC. Crew Mission highlights Commander Malenchenko and Flight Engineer Musabayev, both spaceflight rookies, were to have been launched with veteran cosmonaut Gennadi Strekalov, who would have returned to Earth with Viktor Afanasyev and Yuri Usachov in Soyuz TM-18 after a few days on Mir. However, the cancellation of one of two Progress-M cargo ships scheduled to resupply Mir during the Agat crew's stay meant that Strekalov's couch had to carry supplies. The result was the first all-rookie Soyuz flight since Soyuz 25 in October of 1977. Docking occurred without incident on July 3. Both cosmonauts and Doctor Valeri Polyakov (who had arrived on Soyuz TM-18) became the 16th resident crew; many technical problems with the station arose during this expedition, necessitating a previously-untried manual supply docking by Malenchenko. On November 3, Malenchenko, Musabayev and Merbold undocked in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Extra-vehicular Activity
Extravehicular activity (EVA) is any activity done by an astronaut in outer space outside a spacecraft. In the absence of a breathable Earthlike atmosphere, the astronaut is completely reliant on a space suit for environmental support. EVA includes ''spacewalks'' and lunar or planetary surface exploration (commonly known from 1969 to 1972 as ''moonwalks''). In a stand-up EVA (SEVA), an astronaut stands through an open hatch but does not fully leave the spacecraft. EVA has been conducted by the Soviet Union/Russia, the United States, Canada, the European Space Agency and China. On March 18, 1965, Alexei Leonov became the first human to perform a spacewalk, exiting the Voskhod 2 capsule for 12 minutes and 9 seconds. On July 20, 1969, Neil Armstrong became the first human to perform a moonwalk, outside his lunar lander on Apollo 11 for 2 hours and 31 minutes. On the last three Moon missions, astronauts also performed deep-space EVAs on the return to Earth, to retrieve film canis ...

October Revolution
The October Revolution,. officially known as the Great October Socialist Revolution. in the Soviet Union, also known as the Bolshevik Revolution, was a revolution in Russia led by the Bolshevik Party of Vladimir Lenin that was a key moment in the larger Russian Revolution of 1917–1923. It was the second revolutionary change of government in Russia in 1917. It took place through an armed insurrection in Petrograd (now Saint Petersburg) on . It was the precipitating event of the Russian Civil War. The October Revolution followed and capitalized on the February Revolution earlier that year, which had overthrown the Tsarist autocracy, resulting in a liberal provisional government. The provisional government had taken power after being proclaimed by Grand Duke Michael, Tsar Nicholas II's younger brother, who declined to take power after the Tsar stepped down. During this time, urban workers began to organize into councils (soviets) wherein revolutionaries criticized the pro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vostok 1
Vostok 1 (russian: link=no, Восток, ''East'' or '' Orient'' 1) was the first spaceflight of the Vostok programme and the first human orbital spaceflight in history. The Vostok 3KA space capsule was launched from Baikonur Cosmodrome on April 12, 1961, with Soviet cosmonaut Yuri Gagarin aboard, making him the first human to reach orbital velocity around the Earth and to complete a full orbit around the Earth. The orbital spaceflight consisted of a single orbit around Earth which skimmed the upper atmosphere at at its lowest point. The flight took 108 minutes from launch to landing. Gagarin parachuted to the ground separately from his capsule after ejecting at altitude. Background The Space Race between the Soviet Union and the United States, the two Cold War superpowers, began just before the Soviet Union launched the world's first artificial satellite, Sputnik 1, in 1957. Both countries wanted to develop spaceflight technology quickly, particularly by launching the fi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sputnik 1
Sputnik 1 (; see § Etymology) was the first artificial Earth satellite. It was launched into an elliptical low Earth orbit by the Soviet Union on 4 October 1957 as part of the Soviet space program. It sent a radio signal back to Earth for three weeks before its three silver-zinc batteries ran out, and continued in orbit for three months until aerodynamic drag caused it to fall back into the atmosphere on 4 January 1958. It was a polished metal sphere in diameter with four external radio antennas to broadcast radio pulses. Its radio signal was easily detectable by amateur radio operators, and the 65° orbital inclination made its flight path cover virtually the entire inhabited Earth. The satellite's unanticipated success precipitated the American Sputnik crisis and triggered the Space Race, part of the Cold War. The launch was the beginning of a new era of political, military, technological and scientific developments. The word ''sputnik'' is Russian for ''satellite'' w ...

Kazakhstan
Kazakhstan, officially the Republic of Kazakhstan, is a transcontinental country located mainly in Central Asia and partly in Eastern Europe. It borders Russia to the north and west, China to the east, Kyrgyzstan to the southeast, Uzbekistan to the south, and Turkmenistan to the southwest, with a coastline along the Caspian Sea. Its capital is Astana, known as Nur-Sultan from 2019 to 2022. Almaty, Kazakhstan's largest city, was the country's capital until 1997. Kazakhstan is the world's largest landlocked country, the largest and northernmost Muslim-majority country by land area, and the ninth-largest country in the world. It has a population of 19 million people, and one of the lowest population densities in the world, at fewer than 6 people per square kilometre (15 people per square mile). The country dominates Central Asia economically and politically, generating 60 percent of the region's GDP, primarily through its oil and gas industry; it also has vast mineral ...

Tselinograd
Astana, previously known as Akmolinsk, Tselinograd, Akmola, and most recently Nur-Sultan, is the capital city of Kazakhstan. The city lies on the banks of the Ishim River in the north-central part of Kazakhstan, within the Akmola Region, though administered as a city with special status separately from the rest of the region. A 2020 official estimate reported a population of 1,136,008 within the city limits, making it the second-largest city in the country, after Almaty, which had been the capital until 1997. The city became the capital of Kazakhstan in 1997; since then it has grown and developed economically into one of the most modern cities in Central Asia. In 2021, the government selected Astana as one of the 10 priority destinations for tourist development. Modern Astana is a planned city, following the process of other planned capitals. After it became the capital of Kazakhstan, the city dramatically changed its shape. The city's master-plan was designed by Japanese ar ...

Atmospheric Reentry
Atmospheric entry 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. There are two main types of atmospheric entry: ''uncontrolled entry'', such as the entry of astronomical objects, space debris, or bolides; and ''controlled entry'' (or ''reentry'') of a spacecraft capable of being navigated or following a predetermined course. Technologies and procedures allowing the 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. Crewed space vehicles must be slowed to subsonic speeds be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Spacecraft Docking And Berthing Mechanisms
Docking and berthing of spacecraft is the joining of two spacecraft, space vehicles. This connection can be temporary, or wiktionary:semipermanent, partially permanent such as for space station modules. ''Docking'' specifically refers to joining of two separate free-flying space vehicles. ''Berthing'' refers to mating operations where a passive module/vehicle is placed into the mating interface of another space vehicle by using a robotic arm. Because the modern process of un-berthing requires more crew labor and is time-consuming, berthing operations are unsuited for rapid crew evacuations in the event of an emergency. History Docking Spacecraft docking capability depends on space rendezvous, the ability of two spacecraft to find each other and orbital station-keeping, station-keep in the same orbit. This was first developed by the United States for Project Gemini. It was planned for the crew of Gemini 6A, Gemini 6 to rendezvous and manually dock under the command of Wally ...
