An astronaut or cosmonaut is a person trained by a human spaceflight program to command, pilot, or serve as a crew member of a spacecraft. Although generally reserved for professional space travelers, the terms are sometimes applied to anyone who travels into space, including scientists, politicians, journalists, and tourists.
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.
Until 2002, astronauts were sponsored and trained exclusively by governments, either by the military or by civilian space agencies. With the suborbital flight of the privately funded SpaceShipOne in 2004, a new category of astronaut was created: the commercial astronaut.
SpaceShipOne is an experimental air-launched rocket-powered aircraft with sub-orbital spaceflight capability at speeds of up to 900 m/s (3,000 ft/s), using a hybrid rocket motor. The design features a unique "feathering" atmospheric reentry system where the rear half of the wing and the twin tail booms folds 70 degrees upward along a hinge running the length of the wing; increasing drag while remaining stable. SpaceShipOne completed the first manned private spaceflight in 2004. That same year, it won the US$10 million Ansari X Prize and was immediately retired from active service. Its mother ship was named "White Knight". Both craft were developed and flown by Mojave Aerospace Ventures, which was a joint venture between Paul Allen and Scaled Composites, Burt Rutan's aviation company. Allen provided the funding of approximately US$25 million.
A commercial astronaut is a person trained to command, pilot, or serve as a crew member of a privately funded spacecraft. This is distinct from an otherwise non-government astronaut, for example Charlie Walker, who flies while representing a non-government corporation but with funding and/or training coming from government sources.
The criteria for what constitutes human spaceflight vary. The Fédération Aéronautique Internationale (FAI) Sporting Code for astronautics recognizes only flights that exceed an altitude of 100 kilometers (62 mi). In the United States, professional, military, and commercial astronauts who travel above an altitude of 50 miles (80 km) are awarded astronaut wings.
Human spaceflight is space travel with a crew or passengers aboard the spacecraft. Spacecraft carrying people may be operated directly, by human crew, or it may be either remotely operated from ground stations on Earth or be autonomous, able to carry out a specific mission with no human involvement.
The Fédération aéronautique internationale, is the world governing body for air sports, and also stewards definitions regarding human spaceflight. It was founded on 14 October 1905, and is headquartered in Lausanne, Switzerland. It maintains world records for aeronautical activities including ballooning, aeromodeling, unmanned aerial vehicles (drones), as well as flights into space.
The Kármán line, or Karman line, is an attempt to define a boundary between Earth's atmosphere and outer space. This is important for legal and regulatory measures; aircraft and spacecraft fall under different jurisdictions and are subject to different treaties.
As of 17 November 2016 [update] , a total of 552 people from 36 countries have reached 100 km (62 mi) or more in altitude, of which 549 reached low Earth orbit or beyond. Of these, 24 people have traveled beyond low Earth orbit, either to lunar orbit, the lunar surface, or, in one case, a loop around the Moon. Three of the 24–Jim Lovell, John Young and Eugene Cernan–did so twice. The three current[ when? ] astronauts who have flown without reaching low Earth orbit are spaceplane pilots Joe Walker, Mike Melvill, and Brian Binnie, who participated in suborbital missions.
Since the first human spaceflight by the Soviet Union, citizens of 40 countries have flown in space. For each nationality, the launch date of the first mission is listed. The list is based on the nationality of the person at the time of the launch. Only 3 of the 40 "first flyers" have been women. Only three nations have launched their own crewed spacecraft, with the Soviets/Russians and the American programs providing rides to other nations' astronauts. Twenty-six "first flights" occurred on Soviet or Russian flights while the United States carried thirteen.
A Low Earth Orbit (LEO) is an Earth-centered orbit with an altitude of 2,000 km (1,200 mi) or less, or with at least 11.25 periods per day and an eccentricity less than 0.25. Most of the manmade objects in outer space are in LEO. A histogram of the mean motion of the cataloged objects shows that the number of objects drops significantly beyond 11.25.
James Arthur Lovell Jr. is a former NASA astronaut, Naval Aviator, mechanical engineer, and retired Navy captain. Lovell is known for being the commander of the ill-fated Apollo 13 mission, which suffered a critical failure en route to the Moon but was brought back safely to Earth through the efforts of the crew and mission control. In addition to being part of the Apollo 13 crew, Lovell was the command module pilot of Apollo 8, the first Apollo mission to enter lunar orbit.
As of 17 November 2016 [update] , under the U.S. definition, 558 people qualify as having reached space, above 50 miles (80 km) altitude. Of eight X-15 pilots who exceeded 50 miles (80 km) in altitude, only one exceeded 100 kilometers (about 62 miles). Space travelers have spent over 41,790 man-days (114.5-man-years) in space, including over 100 astronaut-days of spacewalks. As of 2016 [update] , the man with the longest cumulative time in space is Gennady Padalka, who has spent 879 days in space. Peggy A. Whitson holds the record for the most time in space by a woman, 377 days.
Extravehicular activity (EVA) is any activity done by an astronaut or cosmonaut outside a spacecraft beyond the Earth's appreciable atmosphere. The term most commonly applies to a spacewalk made outside a craft orbiting Earth, but also has applied to lunar surface exploration performed by six pairs of American astronauts in the Apollo program from 1969 to 1972. On each of the last three of these missions, astronauts also performed deep-space EVAs on the return to Earth, to retrieve film canisters from the outside of the spacecraft. Astronauts also used EVA in 1973 to repair launch damage to Skylab, the United States' first space station.
Gennady Ivanovich Padalka is a Russian Air Force officer and an RKA cosmonaut. Padalka currently has the world record for the most time spent in space, having spent 879 days in space, more than any other person. He worked on both Mir and the International Space Station.
Peggy Annette Whitson is an American biochemistry researcher, retired NASA astronaut, and former NASA Chief Astronaut. Her first space mission was in 2002, with an extended stay aboard the International Space Station as a member of Expedition 5. Her second mission launched October 10, 2007, as the first female commander of the ISS with Expedition 16. She was on her third long-duration space flight and was the commander of the International Space Station for Expedition 51, before handing over command to Fyodor Yurchikhin on June 1, 2017.
In 1959, when both the United States and Soviet Union were planning, but had yet to launch humans into space, NASA Administrator T. Keith Glennan and his Deputy Administrator, Dr. Hugh Dryden, discussed whether spacecraft crew members should be called astronauts or cosmonauts. Dryden preferred "cosmonaut", on the grounds that flights would occur in the cosmos (near space), while the "astro" prefix suggested flight to the stars. Most NASA Space Task Group members preferred "astronaut", which survived by common usage as the preferred American term.When the Soviet Union launched the first man into space, Yuri Gagarin in 1961, they chose a term which anglicizes to "cosmonaut".
The Soviet Union, officially the Union of Soviet Socialist Republics (USSR), was a socialist state in Eurasia that existed from 1922 to 1991. Nominally a union of multiple national Soviet republics, its government and economy were highly centralized. The country was a one-party state, governed by the Communist Party with Moscow as its capital in its largest republic, the Russian Soviet Federative Socialist Republic. Other major urban centres were Leningrad, Kiev, Minsk, Tashkent, Alma-Ata, and Novosibirsk. It spanned over 10,000 kilometres (6,200 mi) east to west across 11 time zones, and over 7,200 kilometres (4,500 mi) north to south. It had five climate zones: tundra, taiga, steppes, desert and mountains.
The National Aeronautics and Space Administration is an independent agency of the United States Federal Government responsible for the civilian space program, as well as aeronautics and aerospace research.
Thomas Keith Glennan was the first Administrator of the National Aeronautics and Space Administration, serving from August 19, 1958 to January 20, 1961.
In English-speaking nations, a professional space traveler is called an astronaut.The term derives from the Greek words ástron (ἄστρον), meaning "star", and nautes (ναύτης), meaning "sailor". The first known use of the term "astronaut" in the modern sense was by Neil R. Jones in his 1930 short story "The Death's Head Meteor". The word itself had been known earlier; for example, in Percy Greg's 1880 book Across the Zodiac, "astronaut" referred to a spacecraft. In Les Navigateurs de l'Infini (1925) by J.-H. Rosny aîné, the word astronautique (astronautic) was used. The word may have been inspired by "aeronaut", an older term for an air traveler first applied in 1784 to balloonists. An early use of "astronaut" in a non-fiction publication is Eric Frank Russell's poem "The Astronaut", appearing in the November 1934 Bulletin of the British Interplanetary Society .
The first known formal use of the term astronautics in the scientific community was the establishment of the annual International Astronautical Congress in 1950, and the subsequent founding of the International Astronautical Federation the following year.
NASA applies the term astronaut to any crew member aboard NASA spacecraft bound for Earth orbit or beyond. NASA also uses the term as a title for those selected to join its Astronaut Corps.The European Space Agency similarly uses the term astronaut for members of its Astronaut Corps.
By convention, an astronaut employed by the Russian Federal Space Agency (or its Soviet predecessor) is called a cosmonaut in English texts. : космонавт, Russian pronunciation: [kəsmɐˈnaft] ), one who works in space outside the Earth's atmosphere, a space traveler, which derives from the Greek words kosmos (κόσμος), meaning "universe", and nautes (ναύτης), meaning "sailor". Other countries of the former Eastern Bloc use variations of the Russian word kosmonavt, such as the Polish kosmonauta (although Polish also uses astronauta, and the two words are considered synonyms ).The word is an anglicisation of the Russian word kosmonavt (Russian
Coinage of the term kosmonavt has been credited to Soviet aeronautics pioneer Mikhail Tikhonravov (1900–1974). [ citation needed ]The first cosmonaut was Soviet Air Force pilot Yuri Gagarin, also the first person in space. He was part of the first six Russians, with German Titov, Yevgeny Khrunov, Andriyan Nikolayev, Pavel Popovich, and Grigoriy Nelyubov, who were given the title of pilot-cosmonaut in January 1961. Valentina Tereshkova was the first female cosmonaut and the first woman in space. On March 14, 1995, Norman Thagard became the first American to ride to space on board a Russian launch vehicle, and thus became the first "American cosmonaut".
Yǔ háng yuán (宇航员, "Space-universe navigating personnel") is used for astronauts and cosmonauts in general, while hángtiān yuán (航天员, "navigating outer space personnel") is used for Chinese astronauts. Here, hángtiān (航天) is strictly defined as the navigation of outer space within the local star system, i.e. solar system. The phrase tài kōng rén (太空人, "spaceman") is often used in Hong Kong and Taiwan.
The term taikonaut is used by some English-language news media organizations for professional space travelers from China. :太空 (tàikōng, 'space') and the Greek ναύτης (naútēs, 'sailor'); the term became more common in 2003 when China sent its first astronaut Yang Liwei into space aboard the Shenzhou 5 spacecraft. This is the term used by Xinhua News Agency in the English version of the Chinese People's Daily since the advent of the Chinese space program. The origin of the term is unclear; as early as May 1998, Chiew Lee Yih (趙裡昱) from Malaysia, used it in newsgroups.The word has featured in the Longman and Oxford English dictionaries, the latter of which describes it as a hybrid of the Chinese term Chinese
With the rise of space tourism, NASA and the Russian Federal Space Agency agreed to use the term "spaceflight participant" to distinguish those space travelers from professional astronauts on missions coordinated by those two agencies.
While no nation other than Russia (and previously the Soviet Union), the United States, and China have launched a manned spacecraft, several other nations have sent people into space in cooperation with one of these countries, i.e. the Soviet-led Interkosmos programme. Inspired partly by these missions, other synonyms for astronaut have entered occasional English usage. For example, the term spationaut (French spelling: spationaute) is sometimes used to describe French space travelers, from the Latin word spatium for "space", the Malay term angkasawan was used to describe participants in the Angkasawan program, and the Indian Space Research Organisation hope to launch a spacecraft in 2022 that would carry vyomanauts, coined from the Sanskrit word व्योमन् (vyoman meaning 'sky' or 'space'). In Finland, the NASA astronaut Timothy Kopra, a Finnish American, has sometimes been referred to as sisunautti, from the Finnish word sisu .
As of 2019 in the United States, astronaut status is conferred on a person depending on the authorizing agency:
The first human in space was Soviet Yuri Gagarin, who was launched on April 12, 1961, aboard Vostok 1 and orbited around the Earth for 108 minutes. The first woman in space was Soviet Valentina Tereshkova, who launched on June 16, 1963, aboard Vostok 6 and orbited Earth for almost three days.
Alan Shepard became the first American and second person in space on May 5, 1961, on a 15-minute sub-orbital flight. The first American to orbit the Earth was John Glenn, aboard Friendship 7 on February 20, 1962. The first American woman in space was Sally Ride, during Space Shuttle Challenger's mission STS-7, on June 18, 1983.In 1992 Mae Jemison became the first African American woman to travel in space aboard STS-47.
Cosmonaut Alexei Leonov was the first person to conduct an extravehicular activity (EVA), (commonly called a "spacewalk"), on March 18, 1965, on the Soviet Union's Voskhod 2 mission. This was followed two and a half months later by astronaut Ed White who made the first American EVA on NASA's Gemini 4 mission.
The first manned mission to orbit the Moon, Apollo 8 , included American William Anders who was born in Hong Kong, making him the first Asian-born astronaut in 1968.
The Soviet Union, through its Intercosmos program, allowed people from other "socialist" (i.e. Warsaw Pact and other Soviet-allied) countries to fly on its missions, with the notable exception of France participating in Soyuz TM-7. An example is Czechoslovak Vladimír Remek, the first cosmonaut from a country other than the Soviet Union or the United States, who flew to space in 1978 on a Soyuz-U rocket.Rakesh Sharma became the first Indian citizen to travel to space. He was launched aboard Soyuz T-11, on April 2, 1984.
On July 23, 1980, Pham Tuan of Vietnam became the first Asian in space when he flew aboard Soyuz 37.Also in 1980, Cuban Arnaldo Tamayo Méndez became the first person of Hispanic and black African descent to fly in space, and in 1983, Guion Bluford became the first African American to fly into space. In April 1985, Taylor Wang became the first ethnic Chinese person in space. The first person born in Africa to fly in space was Patrick Baudry (France), in 1985. In 1985, Saudi Arabian Prince Sultan Bin Salman Bin AbdulAziz Al-Saud became the first Arab Muslim astronaut in space. In 1988, Abdul Ahad Mohmand became the first Afghan to reach space, spending nine days aboard the Mir space station.
With the increase of seats on the Space Shuttle, the U.S. began taking international astronauts. In 1983, Ulf Merbold of West Germany became the first non-US citizen to fly in a US spacecraft. In 1984, Marc Garneau became the first of 8 Canadian astronauts to fly in space (through 2010).In 1985, Rodolfo Neri Vela became the first Mexican-born person in space. In 1991, Helen Sharman became the first Briton to fly in space. In 2002, Mark Shuttleworth became the first citizen of an African country to fly in space, as a paying spaceflight participant. In 2003, Ilan Ramon became the first Israeli to fly in space, although he died during a re-entry accident.
On October 15, 2003, Yang Liwei became China's first astronaut on the Shenzhou 5 spacecraft.
The youngest person to fly in space is Gherman Titov, who was 25 years old when he flew Vostok 2. (Titov was also the first person to suffer space sickness).The oldest person who has flown in space is John Glenn, who was 77 when he flew on STS-95.
438 days is the longest time spent in space, by Russian Valeri Polyakov. 401,056 km (249,205 mi), when Jim Lovell, Jack Swigert, and Fred Haise went around the Moon during the Apollo 13 emergency.As of 2006, the most spaceflights by an individual astronaut is seven, a record held by both Jerry L. Ross and Franklin Chang-Diaz. The farthest distance from Earth an astronaut has traveled was
The first civilian in space was Valentina Tereshkova 100 kilometers (54 nautical miles) line, qualifying him by the international definition of spaceflight. Walker had joined the US Army Air Force but was not a member during his flight. The first people in space who had never been a member of any country's armed forces were both Konstantin Feoktistov and Boris Yegorov aboard Voskhod 1.aboard Vostok 6 (she also became the first woman in space on that mission). Tereshkova was only honorarily inducted into the USSR's Air Force, which did not accept female pilots at that time. A month later, Joseph Albert Walker became the first American civilian in space when his X-15 Flight 90 crossed the
The first non-governmental space traveler was Byron K. Lichtenberg, a researcher from the Massachusetts Institute of Technology who flew on STS-9 in 1983. million (USD) deal with a Japanese TV station, although at the time, the term used to refer to Akiyama was "Research Cosmonaut". Akiyama suffered severe space sickness during his mission, which affected his productivity.In December 1990, Toyohiro Akiyama became the first paying space traveler as a reporter for Tokyo Broadcasting System, a visit to Mir as part of an estimated $12
The first self-funded space tourist was Dennis Tito on board the Russian spacecraft Soyuz TM-3 on April 28, 2001.
The first person to fly on an entirely privately funded mission was Mike Melvill, piloting SpaceShipOne flight 15P on a suborbital journey, although he was a test pilot employed by Scaled Composites and not an actual paying space tourist.Seven others have paid the Russian Space Agency to fly into space:
The first NASA astronauts were selected for training in 1959.Early in the space program, military jet test piloting and engineering training were often cited as prerequisites for selection as an astronaut at NASA, although neither John Glenn nor Scott Carpenter (of the Mercury Seven) had any university degree, in engineering or any other discipline at the time of their selection. Selection was initially limited to military pilots. The earliest astronauts for both America and the USSR tended to be jet fighter pilots, and were often test pilots.
Once selected, NASA astronauts go through twenty months of training in a variety of areas, including training for extravehicular activity in a facility such as NASA's Neutral Buoyancy Laboratory.Astronauts-in-training (astronaut candidates) may also experience short periods of weightlessness (microgravity) in an aircraft called the "Vomit Comet," the nickname given to a pair of modified KC-135s (retired in 2000 and 2004, respectively, and replaced in 2005 with a C-9) which perform parabolic flights. Astronauts are also required to accumulate a number of flight hours in high-performance jet aircraft. This is mostly done in T-38 jet aircraft out of Ellington Field, due to its proximity to the Johnson Space Center. Ellington Field is also where the Shuttle Training Aircraft is maintained and developed, although most flights of the aircraft are conducted from Edwards Air Force Base.
Astronauts in training must learn how to control and fly the Space Shuttle and, it is vital that they are familiar with the International Space Station so they know what they must do when they get there.
Mission Specialist Educators, or "Educator Astronauts", were first selected in 2004, and as of 2007, there are three NASA Educator astronauts: Joseph M. Acaba, Richard R. Arnold, and Dorothy Metcalf-Lindenburger.Barbara Morgan, selected as back-up teacher to Christa McAuliffe in 1985, is considered to be the first Educator astronaut by the media, but she trained as a mission specialist. The Educator Astronaut program is a successor to the Teacher in Space program from the 1980s.
Astronauts are susceptible to a variety of health risks including decompression sickness, barotrauma, immunodeficiencies, loss of bone and muscle, loss of eyesight, orthostatic intolerance, sleep disturbances, and radiation injury.A variety of large scale medical studies are being conducted in space via the National Space and Biomedical Research Institute (NSBRI) to address these issues. Prominent among these is the Advanced Diagnostic Ultrasound in Microgravity Study in which astronauts (including former ISS commanders Leroy Chiao and Gennady Padalka) perform ultrasound scans under the guidance of remote experts to diagnose and potentially treat hundreds of medical conditions in space. This study's techniques are now being applied to cover professional and Olympic sports injuries as well as ultrasound performed by non-expert operators in medical and high school students. It is anticipated that remote guided ultrasound will have application on Earth in emergency and rural care situations, where access to a trained physician is often rare.
A 2006 Space Shuttle experiment found that Salmonella typhimurium , a bacterium that can cause food poisoning, became more virulent when cultivated in space.More recently, in 2017, bacteria were found to be more resistant to antibiotics and to thrive in the near-weightlessness of space. Microorganisms have been observed to survive the vacuum of outer space.
On December 31, 2012, a NASA-supported study reported that manned spaceflight may harm the brain and accelerate the onset of Alzheimer's disease.
In October 2015, the NASA Office of Inspector General issued a health hazards report related to space exploration, including a human mission to Mars.
Over the last decade, flight surgeons and scientists at NASA have seen a pattern of vision problems in astronauts on long-duration space missions. The syndrome, known as visual impairment intracranial pressure (VIIP), has been reported in nearly two-thirds of space explorers after long periods spent aboard the International Space Station (ISS).
On November 2, 2017, scientists reported that significant changes in the position and structure of the brain have been found in astronauts who have taken trips in space, based on MRI studies. Astronauts who took longer space trips were associated with greater brain changes.
Being in space can be physiologically deconditioning on the body. It can affect the otolith organs and adaptive capabilities of the central nervous system. Zero gravity and cosmic rays can cause many implications for astronauts.
In October 2018, NASA-funded researchers found that lengthy journeys into outer space, including travel to the planet Mars, may substantially damage the gastrointestinal tissues of astronauts. The studies support earlier work that found such journeys could significantly damage the brains of astronauts, and age them prematurely.
Researchers in 2018 reported, after detecting the presence on the International Space Station (ISS) of five Enterobacter bugandensis bacterial strains, none pathogenic to humans, that microorganisms on ISS should be carefully monitored to continue assuring a medically healthy environment for astronauts.
A recent study by Russian scientists published in April 2019 stated that astronauts facing space radiation could face temporary hindrance of their memory centres. While this doesn't affect their intellectual capabilities, it temporarily hinders formation of new cells in brain's memory centres. The study conducted by Moscow Institute of Physics and Technology (MIPT) concluded this after they observed that mice exposed to neutron and gamma radiation didn't impact the rodents' intellectual capabilities.
An astronaut on the International Space Station requires about 0.83 kilograms (1.83 pounds) weight of food inclusive of food packaging per meal each day. (The packaging for each meal weighs around 0.12 kilograms – 0.27 pounds) Longer-duration missions require more food.
Shuttle astronauts worked with nutritionists to select menus that appeal to their individual tastes. Five months before flight, menus are selected and analyzed for nutritional content by the shuttle dietician. Foods are tested to see how they will react in a reduced gravity environment. Caloric requirements are determined using a basal energy expenditure (BEE) formula. On Earth, the average American uses about 35 gallons (132 liters) of water every day. On board the ISS astronauts limit water use to only about three gallons (11 liters) per day.
In Russia, cosmonauts are awarded Pilot-Cosmonaut of the Russian Federation upon completion of their missions, often accompanied with the award of Hero of the Russian Federation. This follows the practice established in the USSR where cosmonauts were usually awarded the title Hero of the Soviet Union.
At NASA, those who complete astronaut candidate training receive a silver lapel pin. Once they have flown in space, they receive a gold pin. U.S. astronauts who also have active-duty military status receive a special qualification badge, known as the Astronaut Badge, after participation on a spaceflight. The United States Air Force also presents an Astronaut Badge to its pilots who exceed 50 miles (80 km) in altitude.
Eighteen astronauts (fourteen men and four women) have lost their lives during four space flights. By nationality, thirteen were American (including one born in India), four were Russian (Soviet Union), and one was Israeli.
Eleven people (all men) have lost their lives training for spaceflight: eight Americans and three Russians. Six of these were in crashes of training jet aircraft, one drowned during water recovery training, and four were due to fires in pure oxygen environments.
The Space Mirror Memorial, which stands on the grounds of the John F. Kennedy Space Center Visitor Complex, commemorates the lives of the men and women who have died during spaceflight and during training in the space programs of the United States. In addition to twenty NASA career astronauts, the memorial includes the names of a U.S. Air Force X-15 test pilot, a U.S. Air Force officer who died while training for a then-classified military space program, and a civilian spaceflight participant.
Yuri Ivanovich Malenchenko is a retired Russian cosmonaut. Malenchenko became the first person to marry in space, on 10 August 2003, when he married Ekaterina Dmitrieva, who was in Texas, while he was 240 miles over New Zealand, on the International Space Station. As of June 2016, Malenchenko ranks second for career time in space due to his time on both Mir and the International Space Station (ISS). He is a former Commander of the International Space Station.
Space Adventures, Inc. is an American space tourism company founded in 1998 by Eric C. Anderson. As of 2010, offerings include zero-gravity atmospheric flights, orbital spaceflights, and other spaceflight-related experiences including cosmonaut training, spacewalk training, and launch tours. Plans announced thus far include sub-orbital and lunar spaceflights. As of October 2009, seven clients have participated in the orbital spaceflight program with Space Adventures, including one person who took two separate trips to space.
Aleksandr Yuriyevich "Sasha" Kaleri is a Russian cosmonaut and veteran of extended stays on the Mir Space Station and the International Space Station (ISS). Kaleri has most recently been in space aboard the ISS serving as a flight engineer for the long duration Expedition 25/26 missions. He has spent the fourth-longest time in space of any person, the longest time in space of any currently active cosmonaut, and the longest time in space of any person not born in what is now Russia.
Yury Valentinovich Lonchakov is a Russian former cosmonaut and a veteran of three space missions. He has spent 200 days in space and has conducted two career spacewalks.
Scott Joseph Kelly is an engineer, a retired American astronaut, and a retired U.S. Navy captain. A veteran of four space flights, Kelly commanded the International Space Station (ISS) on Expeditions 26, 45, and 46.
Fyodor Nikolayevich Yurchikhin, is a Russian cosmonaut of Greek descent, engineer and RSC Energia test-pilot who has flown on five spaceflights. His first spaceflight was a 10-day Space Shuttle mission STS-112. His second was a long-duration stay aboard the International Space Station (ISS) as a Flight Engineer for Expedition 15; for this mission he was launched in the Soyuz TMA-10 spacecraft. He has undertaken two further long-duration stays aboard the ISS, as a crew member of Expedition 24 / 25. For this mission he was launched with the spacecraft Soyuz TMA-19, and he landed in November 2010, also with the TMA-19 spacecraft. He served as Soyuz Commander for his fourth mission aboard Soyuz TMA-09M, as Flight Engineer for Expedition 36 and ISS Commander for Expedition 37. In April 2017, Yurchikhin launched on Soyuz MS-04 for the fifth spaceflight of his career, a six-month mission to the ISS as part of Expedition 51 and 52, for which he was the Commander.
Expedition 2 was the second long-duration spaceflight aboard the International Space Station, immediately following Expedition 1. Its three-person crew stayed aboard the station from March to August 2001. In addition to station maintenance, the crew assisted in several station assembly missions, welcomed the first space tourist Dennis Tito, and conducted some scientific experiments.
The Shuttle–Mir Program was a collaborative space program between Russia and the United States, which involved American Space Shuttles visiting the Russian space station Mir, Russian cosmonauts flying on the shuttle, and an American astronaut flying aboard a Soyuz spacecraft to engage in long-duration expeditions aboard Mir.
Soyuz TMA-11 was a human spaceflight mission using a Soyuz-TMA spacecraft to transport personnel to and from the International Space Station (ISS). The mission began at 13:22 UTC on October 10, 2007 when the spacecraft was launched from the Baikonur Cosmodrome by a Soyuz FG launch vehicle. It brought to the station two members of the ISS Expedition 16 crew, as well as Sheikh Muszaphar, the first Malaysian in space. TMA-11 remained at the station as an escape craft, and returned safely to Earth on April 19, 2008, after it had been replaced by Soyuz TMA-12. Although the vehicle landed safely, it suffered a partial separation failure which caused a ballistic re-entry that in turn caused it to land 475 km from the intended landing point.
A mission patch is a cloth reproduction of a spaceflight mission emblem worn by astronauts and other personnel affiliated with that mission. It is usually executed as an embroidered patch. The term space patch is mostly applied to an emblem designed for a manned space mission. Traditionally, the patch is worn on the space suit that astronauts and cosmonauts wear when launched into space. Mission patches have been adopted by the crew and personnel of many other space ventures, public and private.
Spaceflight began in the 20th century following theoretical and practical breakthroughs by Konstantin Tsiolkovsky and Robert H. Goddard. The Soviet Union took the lead in the post-war Space Race, launching the first satellite, the first man and the first woman into orbit. The United States caught up with, and then passed, their Soviet rivals during the mid-1960s, landing the first man on the Moon in 1969. In the same period, France, the United Kingdom, Japan and China were concurrently developing more limited launch capabilities.
Sergey Aleksandrovich Volkov is a retired Russian cosmonaut and engineer. He was a member of three missions to the International Space Station, spending more than a year in total in space. During his missions he did four spacewalks lasting more than 23 hours in total. Volkov retired from the Cosmonaut group in February 2017.
Aleksandr Mikhailovich Samokutyayev is a former Russian cosmonaut. Samokutyayev served as a Flight Engineer for the International Space Station (ISS) long duration Expedition 27/28 missions.
