Vostok 2
Vostok 2 (, ) was a Soviet space mission which carried cosmonaut Gherman Titov into orbit for a full day on August 6, 1961, to study the effects of a more prolonged period of weightlessness on the human body. Titov orbited the Earth over 17 times, exceeding the single orbit of Yuri Gagarin on Vostok 1 − as well as the suborbital spaceflights of American astronauts Alan Shepard and Gus Grissom aboard their respective Mercury-Redstone 3 and 4 missions. Titov's number of orbits and flight time would not be surpassed by an American astronaut until Gordon Cooper's Mercury-Atlas 9 spaceflight in May 1963. After the flight of Vostok 1, Sergei Korolev took a short vacation in Crimea where he began working out the flight plan for the next mission. There were considerable arguments over the duration of the mission as flight doctors argued for no more than three orbits. The flight of Korabl-Sputnik 2 nine months earlier had carried two dogs on a six orbit mission, during which the a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Soviet Space Program
The Soviet space program () was the state space program of the Soviet Union, active from 1951 until the dissolution of the Soviet Union in 1991. Contrary to its competitors (NASA in the United States, the European Space Agency in Western Europe, and the Ministry of Aerospace Industry in China), which had their programs run under single coordinating agencies, the Soviet space program was divided between several internally competing OKB, design bureaus led by Sergei Korolev, Korolev, Kerim Kerimov, Kerimov, Mstislav Keldysh, Keldysh, Mikhail Yangel, Yangel, Valentin Glushko, Glushko, Vladimir Chelomey, Chelomey, Viktor Makeyev, Makeyev, Boris Chertok, Chertok and Information Satellite Systems Reshetnev, Reshetnev. Several of these bureaus were subordinated to the Ministry of General Machine-Building. The Soviet space program served as an important marker of claims by the Soviet Union to its superpower status.

Astronaut
An astronaut (from the Ancient Greek (), meaning 'star', and (), meaning 'sailor') is a person trained, equipped, and deployed by a List of human spaceflight programs, human spaceflight program to serve as a commander or crew member of a spacecraft. Although generally reserved for professional space travelers, the term is sometimes applied to anyone who travels into space, including scientists, politicians, journalists, and space tourists. "Astronaut" technically applies to all human space travelers regardless of nationality. However, astronauts fielded by Russia or the Soviet Union are typically known instead as cosmonauts (from the Russian "kosmos" (космос), meaning "space", also borrowed from Greek ). Comparatively recent developments in crewed spaceflight made by China have led to the rise of the term taikonaut (from the Standard Chinese, Mandarin "tàikōng" (), meaning "space"), although its use is somewhat informal and its origin is unclear. In China, the People' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Siberia
Siberia ( ; , ) is an extensive geographical region comprising all of North Asia, from the Ural Mountains in the west to the Pacific Ocean in the east. It has formed a part of the sovereign territory of Russia and its predecessor states since the lengthy conquest of Siberia, which began with the fall of the Khanate of Sibir in 1582 and concluded with the annexation of Chukotka in 1778. Siberia is vast and sparsely populated, covering an area of over , but home to roughly a quarter of Russia's population. Novosibirsk, Krasnoyarsk, and Omsk are the largest cities in the area. Because Siberia is a geographic and historic concept and not a political entity, there is no single precise definition of its territorial borders. Traditionally, Siberia spans the entire expanse of land from the Ural Mountains to the Pacific Ocean, with the Ural River usually forming the southernmost portion of its western boundary, and includes most of the drainage basin of the Arctic Ocean.

Pacific Ocean
The Pacific Ocean is the largest and deepest of Earth's five Borders of the oceans, oceanic divisions. It extends from the Arctic Ocean in the north to the Southern Ocean, or, depending on the definition, to Antarctica in the south, and is bounded by the continents of Asia and Australia in the west and the Americas in the east. At in area (as defined with a southern Antarctic border), the Pacific Ocean is the largest division of the World Ocean and the hydrosphere and covers approximately 46% of Earth's water surface and about 32% of the planet's total surface area, larger than its entire land area ().Pacific Ocean .

Korabl-Sputnik 2
Korabl-Sputnik 2 (), also known as Sputnik 5 in the West, was a Soviet artificial satellite, and the third test flight of the Vostok spacecraft. It was the first spaceflight to send animals into orbit and return them safely back to Earth, including two Soviet space dogs, Belka and Strelka. Launched on 19 August 1960, it paved the way for the first human orbital flight, Vostok 1, which was launched less than eight months later. Background Korabl-Sputnik 2 was the second attempt to launch a Vostok capsule with dogs on board. The first try on 28 July, carrying a pair named Bars (Snow Leopard aka Chaika (Seagull)) and Lisichka (Foxie), had been unsuccessful after the Blok G strap-on suffered a fire and breakdown in one of the combustion chambers, followed by its breaking off of the booster 19 seconds after launch. Around 30 seconds, the launch vehicle disintegrated, the core and strap-ons flying in random directions and crashing into the steppe. Flight controllers sent a comman ...

Sergei Korolev
Sergei Pavlovich Korolev (14 January 1966) was the lead Soviet Aerospace engineering, rocket engineer and spacecraft designer during the Space Race between the United States and the Soviet Union in the 1950s and 1960s. He invented the R-7 Semyorka, R-7 Rocket, Sputnik 1, and was involved in the launching of Laika, Sputnik 3, the first luna 2, human-made object to make contact with another celestial body, Soviet space dogs#Belka and Strelka, Belka and Strelka, the first human being, Yuri Gagarin, into space, Voskhod 1, and the first person, Alexei Leonov, to conduct a Voskhod 2, spacewalk. Although Korolev trained as an aircraft designer, his greatest strengths proved to be in design integration, organization and strategic planning. Arrested on a false official charge as a "member of an anti-Soviet counter-revolutionary organization" (which would later be reduced to "saboteur of military technology"), he was imprisoned in 1938 for almost six years, including a few months in a K ...

Mercury-Atlas 9
Mercury-Atlas 9 was the final crewed space mission of the U.S. Mercury program, launched on May 15, 1963, from Launch Complex 14 at Cape Canaveral, Florida. The spacecraft, named ''Faith 7'', completed 22 Earth orbits before splashing down in the Pacific Ocean, piloted by astronaut Gordon Cooper, then a United States Air Force major. The Atlas rocket was No. 130-D, and the Mercury spacecraft was No. 20. As of , this mission marks the last time an American was launched alone to conduct an entirely solo orbital mission.

Gordon Cooper
Leroy Gordon Cooper Jr. (March 6, 1927 – October 4, 2004) was an American aerospace engineer, test pilot, United States Air Force Aviator, pilot, and the youngest of the Mercury Seven, seven original astronauts in Project Mercury, the first human space program of the United States. Cooper learned to fly as a child, and after service in the United States Marine Corps during World War II, he was commissioned into the United States Air Force in 1949. After service as a fighter pilot, he qualified as a test pilot in 1956, and was selected as an astronaut in 1959. In 1963 Cooper piloted the longest and last Mercury spaceflight, Mercury-Atlas 9. During that 34-hour mission he became the first American to spend an entire day in space, the first to sleep in space, and the last American launched on an entirely solo Orbital spaceflight, orbital mission. Despite a series of severe equipment failures, he successfully completed the mission under manual control, guiding his space ...

Mercury-Redstone 4
Mercury-Redstone 4 was the second United States human spaceflight, on July 21, 1961. The suborbital Project Mercury flight was launched with a Mercury-Redstone Launch Vehicle, MRLV-8. The spacecraft, Mercury capsule #11, was nicknamed ''Liberty Bell 7''. It was piloted by astronaut Virgil "Gus" Grissom. The spaceflight lasted 15 minutes 30 seconds, reached an altitude of more than , and flew downrange, landing in the Atlantic Ocean. The flight went as expected until just after splashdown, when the hatch cover, designed to release explosively in the event of an emergency, accidentally blew. Grissom was at risk of drowning, but was recovered safely via a U.S. Navy helicopter. The spacecraft sank into the Atlantic and was not recovered until 1999.

Mercury-Redstone 3
Mercury-Redstone 3, or ''Freedom 7'', was the first United States human spaceflight, on May 5, 1961, piloted by astronaut Alan Shepard. It was the first crewed flight of Project Mercury. The project had the ultimate objective of putting an astronaut into orbit around the Earth and returning him safely. Shepard's mission was a 15-minute sub-orbital spaceflight, suborbital flight with the primary objective of demonstrating his ability to withstand the high g force, g-forces of launch and atmospheric re-entry. Shepard named his space capsule ''Freedom 7'', setting a precedent for the remaining six Mercury astronauts naming their spacecraft and the format of their names, the number 7 later included in all the crewed Mercury spacecraft names not to honor Mercury Seven, NASA's first group of seven astronauts but it stood for the McDonnell Model #7 space capsule used in the Mercury Program. His spacecraft reached an altitude of 101.2 nautical miles (116.5 statute miles, 187.5 kilometer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gus Grissom
Virgil Ivan "Gus" Grissom (April 3, 1926 – January 27, 1967) was an American engineer and pilot in the United States Air Force, as well as one of the original Mercury Seven selected by the NASA, National Aeronautics and Space Administration for Project Mercury, a program to train and launch astronauts into outer space. Grissom went on to be a Project Gemini and Apollo program astronaut for NASA. As a member of the NASA Astronaut Corps, Grissom was the second American to fly in space in 1961. He was also the second American to fly in space twice, preceded only by Joseph A. Walker, Joe Walker with his sub-orbital X-15 flights. Grissom was a World War II and Korean War veteran, mechanical engineer, and United States Air Force, USAF test pilot. He was a recipient of the Distinguished Flying Cross (United States), Distinguished Flying Cross, the Air Medal with an oak leaf cluster, two NASA Distinguished Service Medals, and, posthumously, the Congressional Space Medal of Honor.

Alan Shepard
Alan Bartlett Shepard Jr. (November 18, 1923 – July 21, 1998) was an American astronaut. In 1961, he became the second person and the first American to travel into space and, in 1971, he became the List of Apollo astronauts#Apollo astronauts who walked on the Moon, fifth and oldest person to walk on the Moon, at age 47. A graduate of the United States Naval Academy at Annapolis, Shepard saw action with the surface navy during World War II. He became a naval aviator in 1947, and a test pilot in 1950. He was selected as one of the original NASA Mercury Seven astronauts in 1959, and in May 1961 he made the first crewed Project Mercury flight, Mercury-Redstone 3, in a spacecraft he named ''Freedom 7''. His craft entered space, but was not capable of achieving orbit. He became the second person, and the first American, to travel into space. In the final stages of Project Mercury, Shepard was scheduled to pilot the Mercury-Atlas 10 (MA-10), which was planned as a three-day mi ...
