X-248
The Altair was a solid-fuel rocket with a fiberglass casing, initially developed for use as the third stage of Vanguard rockets in 1959. It was manufactured by Allegany Ballistics Laboratory (ABL) as the X-248. It was also sometimes called the Burner 1. Altair The X-248 was one of two third-stage designs used during Project Vanguard. Early launches used a stage developed by the Grand Central Rocket Company, but later launches used the X-248 which enabled the Vanguard to launch more massive payloads. The X-248 was used as the second stage of some early Thor flights. These vehicles were designated "Thor-Burner". Altairs were used as the third stage of early Delta rockets. The fourth stage of the Scout rocket also used the "Altair" stage. Altair 2 The Altair 2 (X-258) Thiokol solid rocket engine first flew in 1963 and was the kick stage motor for Delta D, Scout A, Scout X-4, and Orbiting Vehicle Orbiting Vehicle or OV, originally designated SATAR (SATellite - A ...

Scout (rocket Family)
The Scout family of rockets were American launch vehicles designed to place small satellites into orbit around the Earth. The Scout multistage rocket was the first orbital launch vehicle to be entirely composed of solid fuel stages. It was also the only vehicle of that type until the successful launch of the Japanese Lambda 4S in 1970. The original Scout (an acronym for Solid Controlled Orbital Utility Test system) was designed in 1957 at the NACA, at Langley center. Scout launch vehicles were used from 1961 until 1994. To enhance reliability the development team opted to use "off the shelf" hardware, originally produced for military programs. According to the NASA fact sheet: "... the first stage motor was a combination of the Jupiter Senior and the Navy Polaris; the second stage came from the Army MGM-29 Sergeant; and the third and fourth stage motors were designed by Langley engineers who adapted a version of the Navy Vanguard." The first successful orbital launch of a Sco ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vanguard Rocket
The Vanguard rocket was intended to be the first launch vehicle the United States would use to place a satellite into orbit. Instead, the Sputnik crisis caused by the surprise launch of Sputnik 1 led the U.S., after the failure of Vanguard TV-3, to quickly orbit the Explorer 1 satellite using a Juno I rocket, making Vanguard 1 the second successful U.S. orbital launch. Vanguard rockets were used by Project Vanguard from 1957 to 1959. Of the eleven Vanguard rockets which the project attempted to launch, three successfully placed satellites into orbit. Vanguard rockets were an important part of the Space Race between the United States and the Soviet Union. Overview In 1955, the United States announced plans to put a scientific satellite in orbit for the International Geophysical Year (IGY) in 1957–1958. The goal was to track the satellite as it performed experiments. At that time, there were three candidates for the launch vehicle: The Air Force's SM-65 Atlas, a derivative of ...

Thor (rocket Family)
Thor was a US space launch vehicle derived from the PGM-17 Thor intermediate-range ballistic missile. The Thor rocket was the first member of the Delta rocket family of space launch vehicles. The last launch of a direct derivative of the Thor missile occurred in 2018 as the first stage of the final Delta II. Thor-Able Thor was first used as a launch vehicle during the testing program of the warhead reentry vehicle for the Atlas missile. For these three tests a Thor core stage was topped by the Able second stage. Able used the Aerojet AJ-10-40 engine from the Vanguard second stage. The first such launch, 116, was lost on 23 April 1958 due to a turbopump failure in the main engine. The recovery of the reentry vehicles on the succeeding two attempts were not successful. Three mice, one on each vehicle, died in these tests. The Able stage from the Atlas reentry vehicle tests was upgraded to become the Able I with a third stage consisting of an unguided Altair X-248 solid-fuel ...

Delta Rocket
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 ...

Lockheed Propulsion Company
The Lockheed Propulsion Company was a division of the Lockheed Aircraft Corporation located at 1500 Crafton Avenue in the Mentone, California area northeast of Redlands, California, adjacent to the Santa Ana River, from 1961 to 1975. It developed, tested and produced solid rocket motors and propellant used in military and National Aeronautics and Space Administration applications. The site consists of approximately 400 acres which was leased from the City of Redlands. The predecessor Grand Central Rocket Company facility was used for the production, testing and disposal of solid rocket propellant used in rocket engines. Lockheed used the facility for research and for production of solid fuel rockets for military and commercial use until 1974. History The Lockheed Propulsion Company was founded in 1952 as the Grand Central Rocket Company by Major C. C. Moseley, co-founder of Western Airlines and Charles E. Bartley, the inventor of rubber-based solid rocket fuel propellants. The com ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Orbiting Vehicle
Orbiting Vehicle or OV, originally designated SATAR (SATellite - Atmospheric Research), comprised five disparate series of standardized American satellites operated by the US Air Force, launched between 1965 and 1971. Forty seven satellites were built, of which forty three were launched and thirty seven reached orbit. With the exception of the OV3 series and OV4-3, they were launched as secondary payloads, using excess space on other missions. This resulted in extremely low launch costs and short proposal-to-orbit times. Typically, OV satellites carried scientific and/or technological experiments, 184 being successfully orbited through the lifespan of the program. The first OV series, designated OV1, was built by General Dynamics and carried on suborbital Atlas missile tests; the satellites subsequently placed themselves into orbit by means of an Altair-2 kick motor. The Northrop-built OV2 satellites were built using parts left over following the cancellation of the Ad ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...
