The Apollo program, also known as Project Apollo, was the third United States human spaceflight program carried out by the National Aeronautics and Space Administration (NASA), which succeeded in preparing and landing the first humans on the Moon from 1968 to 1972. It was first conceived in 1960 during President Dwight D. Eisenhower's administration as a three-person spacecraft to follow the one-person Project Mercury, which put the first Americans in space. Apollo was later dedicated to President John F. Kennedy's national goal for the 1960s of "landing a man on the Moon and returning him safely to the Earth" in an address to Congress on May 25, 1961. It was the third US human spaceflight program to fly, preceded by the two-person Project Gemini conceived in 1961 to extend spaceflight capability in support of Apollo.
Project Vanguard was a program managed by the United States Navy Naval Research Laboratory (NRL), which intended to launch the first artificial satellite into low Earth orbit using a Vanguard rocket. as the launch vehicle from Cape Canaveral Missile Annex, Florida.
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.
A sounding rocket or rocketsonde, sometimes called a research rocket or a suborbital rocket, is an instrument-carrying rocket designed to take measurements and perform scientific experiments during its sub-orbital flight. The rockets are used to launch instruments from 48 to 145 km above the surface of the Earth, the altitude generally between weather balloons and satellites; the maximum altitude for balloons is about 40 km and the minimum for satellites is approximately 121 km. Certain sounding rockets have an apogee between 1,000 and 1,500 km, such as the Black Brant X and XII, which is the maximum apogee of their class. Sounding rockets often use military surplus rocket motors. NASA routinely flies the Terrier Mk 70 boosted Improved Orion, lifting 270–450-kg (600–1,000-pound) payloads into the exoatmospheric region between 97 and 201 km.
The Black Brant is a family of Canadian-designed sounding rockets originally built by Bristol Aerospace, since absorbed by Magellan Aerospace in Winnipeg, Manitoba. Over 800 Black Brants of various versions have been launched since they were first produced in 1961, and the type remains one of the most popular sounding rockets. They have been repeatedly used by the Canadian Space Agency and NASA.
The Saturn IB was an American launch vehicle commissioned by the National Aeronautics and Space Administration (NASA) for the Apollo program. It uprated the Saturn I by replacing the S-IV second stage, with the S-IVB. The S-IB first stage also increased the S-I baseline's thrust from 1,500,000 pounds-force (6,700,000 N) to 1,600,000 pounds-force (7,100,000 N) and propellant load by 3.1%. This increased the Saturn I's low Earth orbit payload capability from 20,000 pounds (9,100 kg) to 46,000 pounds (21,000 kg), enough for early flight tests of a half-fueled Apollo command and service module (CSM) or a fully fueled Apollo Lunar Module (LM), before the larger Saturn V needed for lunar flight was ready.
The Saturn I was a rocket designed as the United States' first medium lift launch vehicle for up to 20,000-pound (9,100 kg) low Earth orbit payloads. The rocket's first stage was built as a cluster of propellant tanks engineered from older rocket tank designs, leading critics to jokingly refer to it as "Cluster's Last Stand". Its development was taken over from the Advanced Research Projects Agency in 1958 by the newly formed civilian NASA. Its design proved sound and flexible. It was successful in initiating the development of liquid hydrogen-fueled rocket propulsion, launching the Pegasus satellites, and flight verification of the Apollo command and service module launch phase aerodynamics. Ten Saturn I rockets were flown before it was replaced by the heavy lift derivative Saturn IB, which used a larger, higher total impulse second stage and an improved guidance and control system. It also led the way to development of the super-heavy lift Saturn V which carried the first men to landings on the Moon in the Apollo program.
Titan IV was a family of heavy-lift space launch vehicles developed by Martin Marietta and operated by the United States Air Force from 1989 to 2005. Launches were conducted from Cape Canaveral Air Force Station, Florida and Vandenberg Air Force Base, California.
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 Nike Apache, also known as Argo B-13, was a two-stage sounding rocket developed by Aerolab, later Atlantic Research, for use by the United States Air Force and NASA. It became the standard NASA sounding rocket and was launched over 600 times between 1961 and 1978.
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.
Javelin was the designation of an American sounding rocket. The four stage Javelin rocket had a payload of around 125 pounds, an apogee of 1100 kilometers, a liftoff thrust of 365 kilonewtons, a total mass of 3,385 kilograms, and a core diameter of 580 millimeters. It was launched 82 times between 1959 and 1976.
The Nike-Cajun was a two-stage sounding rocket built by combining a Nike base stage with a Cajun upper stage. The Nike-Cajun was known as a CAN for Cajun And Nike. The Cajun was developed from the Deacon rocket. It retained the external size, shape and configuration of the Deacon but had 36 percent greater impulse than the Deacon due to improved propellant. It was launched 714 times between 1956 and 1976 and was the most frequently used sounding rocket of the western world. The Nike Cajun had a launch weight of 698 kg (1538 lb), a payload of 23 kg (51 lb), a launch thrust of 246 kN (55,300 lbf) and a maximum altitude of 120 km (394,000 ft). It had a diameter of 42 cm and a length of 7.70 m. The maximum speed of the Nike-Cajun was 6,760 km/h (4,200 mph).
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 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.
Saturn V is a retired American super heavy-lift launch vehicle developed by NASA under the Apollo program for human exploration of the Moon. The rocket was human-rated, with three stages, and powered with liquid fuel. It was flown from 1967 to 1973. It was used for nine crewed flights to the Moon, and to launch Skylab, the first American space station.
Terasca, or Terrier-ASROC-Cajun, was an American three-stage sounding rocket developed and launched by the United States Navy. Derived from a combination of the Terrier, ASROC and Cajun rockets, three launches were attempted during 1959, but only one was successful.
The Nike stage or Nike booster, a solid fuel rocket motor, was created by Hercules Aerospace for the Nike Ajax (M5) Nike Hercules (M5E1). It was developed for use as the first stage of the Nike Ajax and Nike Hercules missiles as part of Project Nike.
Beacon was one of America's first satellite programs. A balloon satellite, its objective was to study atmospheric density at its orbital altitude and to be the first United States satellite visible to the naked eye. Booster problems caused both orbital attempts to end in failure.
