Delta (rocket Family)
Delta is an American versatile family of expendable launch systems that has provided space launch capability in the United States since 1960. Japan also launched license-built derivatives (N-I, N-II, and H-I) from 1975 to 1992. More than 300 Delta rockets have been launched with a 95% success rate. Only the Delta IV Heavy rocket remains in use as of November 2020. Delta rockets have stopped being manufactured in favor of Vulcan. Origins The original Delta rockets used a modified version of the PGM-17 Thor, the first ballistic missile deployed by the United States Air Force (USAF), as their first stage. The Thor had been designed in the mid-1950s to reach Moscow from bases in Britain or similar allied nations, and the first wholly successful Thor launch had occurred in September 1957. Subsequent satellite and space probe flights soon followed, using a Thor first stage with several different upper stages. The fourth upper stage used on the Thor was the Thor "Delta", delt ...

Delta C
The Delta C, or Thor-Delta C was an American expendable launch system used for thirteen orbital launches between 1963 and 1969. It was a member of the Delta family of rockets. The first stage was a Thor missile in the DSV-2A configuration, and the second stage was the Delta D, which was derived from the earlier Delta. The baseline Delta C used an Altair-2 third stage, whilst the Delta C1 had an FW-4D third stage, which provided a higher payload capacity than the Altair. It is unclear whether two or three launches were made using the C1 configuration. The Delta C was launched from Cape Canaveral Air Force Station Launch Complex 17. Most launches carried NASA research satellites into low Earth orbit A low Earth orbit (LEO) is an orbit around Earth with a period of 128 minutes or less (making at least 11.25 orbits per day) and an eccentricity less than 0.25. Most of the artificial objects in outer space are in LEO, with an altitude never mor .... References Delta (rock ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Delta J .
The Delta J, or Thor-Delta J was an American expendable launch system of the late 1960s. Only one was launched, with the Explorer 38 spacecraft. It was a member of the Delta family of rockets. The Delta J was derived from the Delta E. The first stage was a Thor missile in the DSV-2C configuration, with three Castor-1 solid rocket boosters clustered around it. A Delta E was used as the second stage. The Altair third stage of the Delta E was replaced with the more powerful Star 37D SRM. The only Delta J to fly was launched from Vandenberg Air Force Base Space Launch Complex 2E on 4 July 1968. It successfully placed the Explorer 38 satellite into 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.

Biosatellite 2
Biosatellite 2, also known as Biosat 2 or Biosatellite B, was the second mission in NASA's Biosatellite program for biological research. It was launched on September 7, 1967, by a Delta G rocket from Cape Canaveral Air Force Station in Florida. Biosatellite 2 carried 13 biological experiments involving insects, frog eggs, plants and microorganisms. The mission was ended early because of a tropical storm threat in the recovery area and communication problems between the capsule and ground stations. The main objective of the mission was to determine if the radiation sensitivity of living organisms in space is greater or less than on land, for which disposed of a radiation source in front of the capsule. The satellite is currently the property of the National Air and Space Museum, reference numbeA19731629000 It is currently on loan to the Museum of Science and Industry, Chicago.

Biosatellite 1
Biosatellite 1, also known as Biosat 1 and Biosatellite A, was the first mission in NASA's Biosatellite program. It was launched on December 14, 1966, by a Delta G rocket from Launch Complex 17A of the Cape Canaveral Air Force Station into an orbit with a perigee, apogee, and 33.5 degrees of orbital inclination, with a period of 90.5 minutes. Biosatellite 1 was carrying several specimens for studying the effects of the space environment on biological processes. Prior to reentry, the entry capsule separated from the satellite bus properly, but the deorbit motor failed to ignite, leaving it stranded in a slowly decaying orbit. It re-entered and disintegrated on February 15, 1967.

Delta G
The Delta G, or Thor-Delta G was an American expendable launch system used to launch two biological research satellites in 1966 and 1967. It was a member of the Delta family of rockets. The Delta G was a two-stage derivative of the Delta E. The first stage was a Thor missile in the DSV-2C configuration and the second stage was a Delta E. Three Castor-1 solid rocket boosters were clustered around the first stage. The solid-fuel upper stage used on the Delta E was not used on the Delta G. Both launches occurred from Cape Canaveral Air Force Station Launch Complex 17. The first was from pad 17A on 14 December 1966 at 19:20 GMT, with Biosatellite 1. At 22:04 on 7 September 1967, Biosatellite 2 Biosatellite 2, also known as Biosat 2 or Biosatellite B, was the second mission in NASA's Biosatellite program for biological research.

European Space Research Organisation
The European Space Research Organisation (ESRO) was an international organisation founded by 10 European nations with the intention of jointly pursuing scientific research in space. It was founded in 1964. As an organisation ESRO was based on a previously existing international scientific institution, CERN. The ESRO convention, the organisations founding document outlines it as an entity exclusively devoted to scientific pursuits. This was the case for most of its lifetime but in the final years before the formation of ESA, the European Space Agency, ESRO began a programme in the field of telecommunications. Consequently, ESA is not a mainly pure science focused entity but concentrates on telecommunications, earth observation and other application motivated activities. ESRO was merged with ELDO in 1975 to form the European Space Agency. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Delta E
The Delta E, or Thor-Delta E was an American expendable launch system used for twenty-three orbital launches between 1965 and 1971. It was a member of the Delta family of rockets. The first stage was a Thor missile in the DSV-2C configuration, and the second stage was thDelta-E which was derived from the earlie Three Castor-1 solid rocket boosters were clustered around the first stage. Two different solid-fuel upper stages were available; an Altair-2 was used on the baseline version, however this could be replaced with an FW-4D to increase performance. A Delta E with the FW-4D upper stage was designated Delta E1. Six flights used the Delta E configuration and seventeen used the Delta E1. Delta E rockets were launched from Cape Canaveral Air Force Station Launch Complex 17 and Vandenberg Air Force Base Space Launch Complex 2E. All 23 flights were successful. On December 16 1965, a Delta E launched the Pioneer 6 space probe A space probe is an artificial satellite that ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Intelsat I
Intelsat I (nicknamed Early Bird for the proverb "The early bird catches the worm") was the first commercial communications satellite to be placed in geosynchronous orbit, on April 6, 1965. It was built by the Space and Communications Group of Hughes Aircraft Company (later Hughes Space and Communications Company, and now Boeing Satellite Systems) for COMSAT, which activated it on June 28, 1965. It was based on the Syncom series of satellites that Hughes had previously built for NASA to demonstrate that communications via synchronous-orbit satellite were feasible. Its booster was a Thrust Augmented Delta (Delta D). After a series of maneuvers, it reached its geosynchronous orbital position over the Atlantic Ocean at 28° West longitude, where it was put into service. It helped provide the first live TV coverage of a spacecraft splashdown, that of Gemini 6 in December 1965. Originally slated to operate for 18 months, Early Bird was in active service for 4 years and 4 months, bein ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Geostationary Orbit
A geostationary orbit, also referred to as a geosynchronous equatorial orbit''Geostationary orbit'' and ''Geosynchronous (equatorial) orbit'' are used somewhat interchangeably in sources. (GEO), is a circular geosynchronous orbit in altitude above Earth's equator ( in radius from Earth's center) and following the direction of Earth's rotation. An object in such an orbit has an orbital period equal to Earth's rotational period, one sidereal day, and so to ground observers it appears motionless, in a fixed position in the sky. The concept of a geostationary orbit was popularised by the science fiction writer Arthur C. Clarke in the 1940s as a way to revolutionise telecommunications, and the first satellite to be placed in this kind of orbit was launched in 1963. Communications satellites are often placed in a geostationary orbit so that Earth-based satellite antennas do not have to rotate to track them but can be pointed permanently at the position in the sky where the sat ...

Castor (rocket Stage)
The Castor family of solid-fuel rocket stages and boosters built by Thiokol (now Northrop Grumman) and used on a variety of launch vehicles. They were initially developed as the second-stage motor of the Scout rocket. The design was based on the MGM-29 Sergeant, a surface-to-surface missile developed for the United States Army at the Jet Propulsion Laboratory. Versions Flown versions Castor 1 :The Castor 1 was first used for a successful suborbital launch of a Scout X-1 rocket on September 2, 1960. :It was long, in diameter, and had a burn time of 27 seconds. Castor 1 stages were also used as strap-on boosters for launch vehicles using Thor first stages, including the Delta-D. (A Delta-D was used in 1964 to launch Syncom-3, the first satellite placed in a geostationary orbit.) Castor 1 stages were used in 141 launch attempts of Scout and Delta rockets, only 2 of which were failures. They were also used on some thrust-assisted Thor-Agena launchers. The last launch usin ...

Delta D
The Delta D, Thrust Augmented Delta or Thor-Delta D was an American expendable launch system used to launch two communications satellites in 1964 and 1965. It was derived from the Delta C, and was a member of the Delta family of rockets. The three-stage core vehicle was essentially the same as the Delta C. The first stage was a Thor missile in the DSV-2A configuration, and the second stage was thDelta-D which was derived from the earlie An Altair-2 SRM was used as a third stage. The main difference between the Delta C and Delta D was the presence of three Castor-1 solid rocket boosters, clustered around the first stage. Both Delta D launches were conducted from Cape Canaveral Air Force Station Launch Complex 17A. The first, on 19 August 1964, carried Syncom 3, the first satellite in a geostationary orbit. The last, on 6 April 1965, carried the first commercial communications satellite, Intelsat I Intelsat I (nicknamed Early Bird for the proverb "The early bird catches the ...
