TheRedstone family of rockets consisted of a number of Americanballistic missiles,sounding rockets andexpendable launch vehicles operational during the 1950s and 1960s. The first member of the Redstone family was thePGM-11 Redstone missile, from which all subsequent variations of the Redstone were derived. TheJuno 1 version of the Redstone launchedExplorer 1, the first U.S. orbital satellite in 1958 and theMercury-Redstone variation carried the first two U.S. astronauts into space in 1961. The rocket was named for theRedstone Arsenal in Huntsville, Alabama where it was developed.[1]
First launched in 1953, thePGM-11 Redstone was a short-range surface-to-surface ballistic missile in active service with theU.S. Army from June 1958 to June 1964; and was used for the first U.S. live nuclear missile tests. It was built byChrysler for the United StatesArmy Ballistic Missile Agency (ABMA) and was deployed inWest Germany.George Huebner was the executive engineer in charge of Chrysler's missile program for its first two years of operation.[2][3]
Jupiter-A was the first variant of Redstone, used to test components later used in thePGM-19 Jupiter medium-range ballistic missile.
Jupiter-C was asounding rocket used for threesub-orbital spaceflights in 1956 and 1957. It was used as a testbed forre-entry vehicles later deployed on the PGM-19 Jupiter.

Juno I was a derivative of the Jupiter-C, used to launch the first American satellite,Explorer 1, on January 31, 1958. Although the U.S. possibly could have put a satellite into orbit before theSoviet Union had the ABMA been allowed to attempt a satellite launch in August 1956, the Eisenhower administration wanted the first U.S. satellite to be launched by a civilian rocket developed by American engineers instead of a rocket derived from a military missile program and developed by the German engineers ofOperation Paperclip. Additionally, the administration saw value in the USSR taking the first move to reach orbit because they would set the precedent that territorial overflight in space was fair game, necessary for the United States' space-based photoreconaissance ambitions in the wake of diplomatic protests againstU-2 incursions of Soviet airspace.
TheVanguard launch vehicle was the civilian rocket program in development for this purpose, so the administration ordered ABMA's research director,Wernher von Braun, not to attempt any satellite launches. The Vanguard rocket failed on its first attempt to launch theVanguard satellite in December 1957, crashing back to the pad and exploding. Following this setback and in the wake of theSputnik crisis, the administration changed course and turned to the Army, asking ABMA and von Braun to launch theJPL-built satellite as soon as possible.
TheMercury-Redstone Launch Vehicle (MRLV), also known as Mercury-Redstone, used the stretched Redstone configuration from the Jupiter-C for six suborbital launches forProject Mercury in 1960 and 1961, including United States' first twohuman spaceflights:
Sparta was the name given to a series of surplus Redstone missiles with two solid-fuel upper stages launched as part of a joint US-UK research project with Australia from 1966 to 1967. Sparta launched Australia's first Earth satellite,WRESAT.
Two members of theSaturn family of rockets, theSaturn I andIB, were partially derived from the Redstone. They used eight tanks built on Redstone tooling clustered around one propellant tank built on Jupiter missile tooling, and used eightRocketdyne H-1 (Jupiter) engines to form the first stage of the rockets. First developed by the ABMA, the Saturn rocket was adopted by NASA for itsApollo program. America's first heavy-lift launch vehicles,the first of these was launched in 1961.
