Spaceflight
Spaceflight (or space flight) is an application of astronautics to fly objects, usually spacecraft, into or through outer space, either with or without humans on board. Most spaceflight is uncrewed and conducted mainly with spacecraft such as satellites in orbit around Earth, but also includes space probes for flights beyond Earth orbit. Such spaceflights operate either by telerobotic or autonomous control. The first spaceflights began in the 1950s with the launches of the Soviet Sputnik satellites and American Explorer and Vanguard missions. Human spaceflight programs include the Soyuz, Shenzhou, the past Apollo Moon landing and the Space Shuttle programs. Other current spaceflight are conducted to the International Space Station and to China's Tiangong Space Station. Spaceflights include the launches of Earth observation and telecommunications satellites, interplanetary missions, the rendezvouses and dockings with space stations, and crewed spaceflights on sci ...

Atlas-Agena
The Atlas-Agena was an American expendable launch system derived from the SM-65 Atlas missile. It was a member of the Atlas (rocket family), Atlas family of rockets, and was launched 109 times between 1960 and 1978. It was used to launch the first five Mariner program, Mariner uncrewed probes to the planets Venus and Mars, and the Ranger program, Ranger and Lunar Orbiter program, Lunar Orbiter uncrewed probes to the Moon. The upper stage was also used as an uncrewed orbital Agena target vehicle, target vehicle for the Project Gemini, Gemini crewed spacecraft to practice space rendezvous, rendezvous and docking and berthing of spacecraft, docking. However, the launch vehicle family was originally developed for the Air Force and most of its launches were classified DoD payloads. The Atlas-Agena was a two-and-a-half-stage rocket, with a SM-65 Atlas#'Stage-and-a-half', stage-and-a-half Atlas missile as the first stage, and an RM-81 Agena second stage. Initially, SM-65D Atlas, Atlas D m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kosmos 35
Kosmos 35 ( meaning ''Cosmos 35'') or Zenit-2 No.20 was a Soviet, first generation, low resolution, optical film-return reconnaissance satellite launched in 1964. A Zenit-2 spacecraft, Kosmos 35 was the twentieth of eighty-one such satellites to be launched and had a mass of . Kosmos 35 was launched by a Vostok-2 rocket, serial number R15001-03, flying from Site 31/6 at the Baikonur Cosmodrome. The launch took place at 11:31 GMT on 15 July 1964, and following its successful arrival in orbit the spacecraft received its Kosmos designation; along with the International Designator 1964-039A and the Satellite Catalog Number 00833. Kosmos 35 was operated in a low Earth orbit, it had a perigee of , an apogee of , inclination of 51.3° and an orbital period The orbital period (also revolution period) is the amount of time a given astronomical object takes to complete one orbit around another object. In astronomy, it usually applies to planets or asteroids orbiting the Sun, moon ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Baikonur Cosmodrome Site 31
Baikonur Site 31, also designated as Site 31/6, is a launch complex at the Baikonur Cosmodrome in Kazakhstan. It serves as a key launch site, supporting Soyuz-2 launches for both crewed and uncrewed missions. The site was first utilized on 14 January 1961 for a test flight of the R-7A, an intercontinental ballistic missile on which the Soyuz rocket family was based. Since 2020, following Roscosmos' transition from the Soyuz-FG to the Soyuz-2 rocket for crewed missions, Site 31 has become the primary launch site for Soyuz flights to the International Space Station (ISS). This shift occurred after Site 1/5, also known as Gagarin's Start, failed to secure funding for upgrades to accommodate the slightly larger Soyuz-2 rocket. Before that, it only saw a handful of crewed flights when Site 1/5 was unavailable. History Construction of Site 31/6 at Baikonur began in late 1958 as a second launch complex for the R-7 intercontinental ballistic missile (ICBM) at the cosmodrome. The ...

Vostok-2 (rocket)
The Vostok-2 ( meaning ''"East"''), GRAU index 8A92 was an expendable carrier rocket used by the Soviet Union between 1962 and 1967. Forty five were launched, of which five failed. It was derived from the earlier Vostok-K, with uprated engines. It was a member of the Vostok family of rockets. The Vostok-2 switched to the newer 8K74 core and featured the 8D74K first stage engines from the Molniya 8K78 booster which gave it improved performance over the older Vostok 8K72K. The Vostok-2 made its maiden flight on 1 June 1962, from Site 1/5 at the Baikonur Cosmodrome. One of the booster engines shut down 1.8 seconds after launch, and the rocket came down away from the pad. The resulting explosion damaged the launch complex, and necessitated delays to several other launches that had been scheduled from that complex, including Vostok 3 and Vostok 4. Thirteen months later, on 10 July 1963, an almost identical failure occurred. The other three failures were caused by a second stage malf ...

Vandenberg AFB Space Launch Complex 3
Space Launch Complex 3 (SLC-3) is a launch site at Vandenberg Space Force Base that consists of two separate launch pads. Space Launch Complex 3 East (SLC-3E) was used by the Atlas V launch vehicle before it was decommissioned in August 2021 with the final launch taking place on List of Atlas launches (2020–2029), November 10, 2022, at 09:49, while Space Launch Complex 3 West (SLC-3W) has been demolished. Launches from Vandenberg fly southward, allowing payloads to be placed in high-inclination orbits such as polar orbit, polar or Sun-synchronous orbit, which allow full global coverage on a regular basis and are often used for weather satellite, weather, Earth observation satellite, Earth observation, and reconnaissance satellites. These orbits are difficult to reach from Cape Canaveral Space Force Station, where launches must fly eastward due to major population centers to both the north and south of Kennedy Space Center. Avoiding these would require hugely inefficient maneuve ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Highly Elliptical Orbit
A highly elliptical orbit (HEO) is an elliptic orbit with high eccentricity, usually referring to one around Earth. Examples of inclined HEO orbits include Molniya orbits, named after the Molniya Soviet communication satellites which used them, and Tundra orbits. Many US satellites also have used these orbits, satellites such as the Trumpet electronics intelligence satellites. The acronym HEO normally is expanded to Highly Eccentric Orbit by orbital analysts since all orbits around planets, etc are ellipses - the term "highly elliptical" is not very clear as to what is exaggerated. It would be more proper to call these orbits "elongated" than "highly elliptical". Highly eccentric orbits have two main uses - as transfer orbits and as good orbits for communication with or surveillance of the Polar regions. The transfer orbit was proposed by the German scientist Walter Hohmann in 1925, it connects two circular orbits, a lower one and a higher one, with an eccentric orbit. Ther ...

Elektron 4
Elektron (, ), in American sources sometimes called Electron, was the first Soviet multiple satellite program, comprising two identical pairs of particle physics satellites launched by the Soviet Union in 1964. The four spacecraft simultaneously monitored the lower and upper Van Allen radiation belts and returned a considerable volume of data regarding radiation in space and atmospheric conditions to an altitude of more than above the Earth. Two of the four launched satellites are still in orbit as of 2023, the other two having reentered. History On 23 June 1960, Soviet spaceflight engineer Sergei Korolev's "big space plan" for the future of Soviet space endeavors was approved by the Central Committee of the Communist Party and the Council of Soviet Ministers. The plan included provisions for the development of scientific spacecraft to map Earth's Van Allen radiation belts. Per decrees on 9 May 1960 and 13 May 1961, the satellites would consist of two identical pairs of s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Medium Earth Orbit
A medium Earth orbit (MEO) is an geocentric orbit, Earth-centered orbit with an altitude above a low Earth orbit (LEO) and below a high Earth orbit (HEO) – between above sea level.''Catalog of Earth Satellite Orbits'' NASA Earth Observatory. 4 September 2009. Accessed 2 May 2021. The boundary between MEO and LEO is an arbitrary altitude chosen by accepted convention, whereas the boundary between MEO and HEO is the particular altitude of a geosynchronous orbit, in which a satellite takes 24 hours to circle the Earth, the same period as the Earth’s own rotation. All satellites in MEO have an orbital period of less than 24 hours, with the minimum period (for a circular orbit at the lowest MEO altitude) about 2 hours. Satellites in MEO or ...

Vostok-K
The Vostok-K ( meaning ''"East"''), GRAU index 8K72K was an expendable carrier rocket used by the Soviet Union for thirteen launches between 1960 and 1964, six of which were crewed. It incorporated several modifications to the core and strap-ons to man-rate them and the Blok E stage also had the improved RD-0109 engine to correct some deficiences in the RD-0105 used on earlier 8K78s. It was a member of the Vostok family of rockets. The Vostok-K made its maiden flight on 22 December 1960, three weeks after the retirement of the Vostok-L. The third stage engine failed 425 seconds after launch, and the payload, a Korabl-Sputnik spacecraft, failed to reach orbit. The spacecraft was recovered after landing, and the two dogs aboard the spacecraft survived the flight. On 12 April 1961, a Vostok-K rocket was used to launch Vostok 1, the first human spaceflight, making Yuri Gagarin the first human to fly in space. All six crewed missions of the Vostok programme The Vostok progra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
