The Army Ballistic Missile Agency (ABMA) was formed to develop the U.S. Army's first large ballistic missile. The agency was established at Redstone Arsenal on 1 February 1956, and commanded by Major General John B. Medaris with Wernher von Braun as technical director.
The Aerobee rocket was one of the United States' most produced and productive sounding rockets. Developed by the Aerojet Corporation, the Aerobee was designed to combine the altitude and launching capability of the V-2 with the cost effectiveness and mass production of the WAC Corporal. More than 1000 Aerobees were launched between 1947 and 1985, returning vast amounts of astronomical, physical, aeronomical, and biomedical data.
James Alfred Van Allen was an American space scientist at the University of Iowa. He was instrumental in establishing the field of magnetospheric research in space.
The R-2 was a Soviet short-range ballistic missile developed from and having twice the range as the R-1 missile. Developed from 1946-1951, the R-2 entered service in numbers in 1953 and was deployed in mobile units throughout the Soviet Union until 1962. A sounding rocket derivative, the R-2A, tested a prototype of the dog-carrying capsule flown on Sputnik 2 in 1957. The same year, the R-2 was licensed for production in The People's Republic of China, where it entered service as the Dongfeng 1.
The PGM-19 Jupiter was the first nuclear armed, medium-range ballistic missile (MRBM) of the United States Air Force (USAF). It was a liquid-propellant rocket using RP-1 fuel and LOX oxidizer, with a single Rocketdyne LR79-NA rocket engine producing 667 kilonewtons (150,000 lbf) of thrust. It was armed with the 1.44 megatons of TNT (6.0 PJ) W49 nuclear warhead. The prime contractor was the Chrysler Corporation.
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.
The Aerojet General X-8 was an unguided, spin-stabilized sounding rocket designed to launch a 150 lb (68 kg) payload to 200,000 feet (61.0 km). The X-8 was a version of the prolific Aerobee rocket family.
Viking was a series of twelve sounding rockets designed and built by the Glenn L. Martin Company under the direction of the U.S. Naval Research Laboratory (NRL). Designed to supersede the German V-2, the Viking was the most advanced large, liquid-fueled rocket developed in the United States in the late 1940s, returning valuable scientific data from the edge of space between 1949 and 1955. Viking 4, launched in 1950, was the first sounding rocket to be launched from the deck of a ship.
The WAC Corporal was the first sounding rocket developed in the United States and the first vehicle to achieve hypersonic speeds. It was an offshoot of the Corporal program, that was started by a partnership between the United States Army Ordnance Corps and the California Institute of Technology in June 1944 with the ultimate goal of developing a military ballistic missile.
The first orbital flight of an artificial satellite, Sputnik 1, was launched in October 1957, by the Soviet Union. In November, the second orbital flight took place. The Soviet Union launched the first animal to orbit the Earth, a dog, Laika, who died in orbit a few hours after launch.
Spaceflight as a practical endeavor began during World War II with the development of operational liquid-fueled rockets. Beginning life as a weapon, the V-2 was pressed into peaceful service after the war at the United States' White Sands Missile Range as well as the Soviet Union's Kapustin Yar. This led to a flourishing of missile designs setting the stage for the exploration of space. The small American WAC Corporal rocket was evolved into the Aerobee, a much more powerful sounding rocket. Exploration of space began in earnest in 1947 with the flight of the first Aerobee, 46 of which had flown by the end of 1950. These and other rockets, both Soviet and American, returned the first direct data on air density, temperature, charged particles and magnetic fields in the Earth's upper atmosphere.
Project Hermes was a missile research program run by the Ordnance Corps of the United States Army from November 15, 1944, to December 31, 1954, in response to Germany's rocket attacks in Europe during World War II. The program was to determine the missile needs of army field forces. A research and development partnership between the Ordnance Corps and General Electric started November 20, 1944 and resulted in the "development of long-range missiles that could be used against both ground targets and high-altitude aircraft."
This is a list of spaceflight related events which occurred in 1956.
In 1955, both the United States and the Soviet Union (USSR) announced plans for launching the world's first satellites during the International Geophysical Year (IGY) of 1957–58. Project Vanguard, proposed by the US Navy, won out over the US Army's Project Orbiter as the satellite and rocket design to be flown in the IGY. Development of Intercontinental Ballistic Missiles, the Atlas by the US and the R-7 by the USSR, accelerated, entering the design and construction phase.
The year 1954 saw the conception of Project Orbiter, the first practicable satellite launching project, utilizing the Redstone, a newly developed Short Range Ballistic Missile.
The year 1951 saw extensive exploration of space by the United States and the Soviet Union (USSR) using suborbital rockets. The Soviets launched their first series of biomedical tests to the 100-kilometre (62 mi) boundary of space. Several American agencies launched more than a dozen scientific sounding rocket flights between them. The US Navy launched its Viking sounding rocket for the seventh time since 1949, this time to a record-breaking 136 miles (219 km) in August 1951.
Strela is a Russian orbital carrier rocket, derived from the Soviet/Russian UR-100NU missile. It conducted its maiden test launch on 5 December 2003, carried its first functional payload on 27 June 2013, and a second one on 19 December 2014.
Milton William Rosen was a United States Navy engineer and project manager in the US space program between the end of World War II and the early days of the Apollo Program. He led development of the Viking and Vanguard rockets, and was influential in the critical decisions early in NASA's history that led to the definition of the Saturn rockets, which were central to the eventual success of the American Moon landing program. He died of prostate cancer in 2014.
The year 1953 saw the rockoon join the stable of sounding rockets capable of reaching beyond the 100 kilometres (62 mi) boundary of space. Employed by both the University of Iowa and the Naval Research Laboratory, 22 total were launched from the decks of the USS Staten Island and the USCGC Eastwind this year. All branches of the United States military continued their program of Aerobee sounding rocket launches, a total of 23 were launched throughout 1953. The Soviet Union launched no sounding rockets in 1953; however, the Soviet Union did conduct several series of missile test launches.
