Explorer 1 was the first satellite launched by the United States in 1958 and was part of the U.S. participation in the International Geophysical Year (IGY). The mission followed the first two satellites, both launched by the Soviet Union during the previous year, Sputnik 1 and Sputnik 2. This began a Space Race during the Cold War between the two nations.
The Jupiter-C was an American research and development vehicle developed from the Jupiter-A. Jupiter-C was used for three uncrewed sub-orbital spaceflights in 1956 and 1957 to test re-entry nosecones that were later to be deployed on the more advanced PGM-19 Jupiter mobile missile. The recovered nosecone was displayed in the Oval Office as part of President Dwight D. Eisenhower's televised speech on November 7, 1957.
The Juno I was a four-stage American space launch vehicle, used to launch lightweight payloads into low Earth orbit. The launch vehicle was used between January 1958 to December 1959. The launch vehicle is a member of the Redstone launch vehicle family, and was derived from the Jupiter-C sounding rocket. It is commonly confused with the Juno II launch vehicle, which was derived from the PGM-19 Jupiter medium-range ballistic missile. In 1958, a Juno I launch vehicle was used to launch America's first satellite, Explorer 1.
Redstone Arsenal is a United States Army base adjacent to Huntsville, Alabama in the Wheeler National Wildlife Refuge. A census-designated place in Madison County, Alabama, United States, it is part of the Huntsville-Decatur Combined Statistical Area. The Arsenal is a host to over 75 tenant agencies including the Department of Defense (DoD), Department of Justice (DOJ), the Federal Bureau of Investigation (FBI), and NASA's largest field center, the Marshall Space Flight Center.
The George C. Marshall Space Flight Center (MSFC), located in Redstone Arsenal, Alabama, is the U.S. government's civilian rocketry and spacecraft propulsion research center. As the largest NASA center, MSFC's first mission was developing the Saturn launch vehicles for the Apollo program. Marshall has been the lead center for the Space Shuttle main propulsion and external tank; payloads and related crew training; International Space Station (ISS) design and assembly; computers, networks, and information management; and the Space Launch System. Located on the Redstone Arsenal near Huntsville, MSFC is named in honor of General of the Army George C. Marshall.
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 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.
James Alfred Van Allen was an American space physicist at the University of Iowa. He was instrumental in establishing the field of magnetospheric research in space.
The Saturn family of American rockets was developed by a team of former German rocket engineers and scientists led by Wernher von Braun to launch heavy payloads to Earth orbit and beyond. The Saturn family used liquid hydrogen as fuel in the upper stages. Originally proposed as a military satellite launcher, they were adopted as the launch vehicles for the Apollo Moon program. Three versions were built and flown: the medium-lift Saturn I, the heavy-lift Saturn IB, and the super heavy-lift Saturn V.
Explorer 2 was an American unmanned space mission within the Explorer program. Intended to be a repetition of the previous Explorer 1 mission, which placed a satellite into medium Earth orbit, the spacecraft was unable to reach orbit due to a failure in the launch vehicle during launch.
Explorer 3 was an American artificial satellite launched into medium Earth orbit in 1958. It was the second successful launch in the Explorer program, and was nearly identical to the first U.S. satellite Explorer 1 in its design and mission.
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.
Space Race is a BBC docudrama series first shown in Britain on BBC2 between 14 September and 5 October 2005, chronicling the major events and characters in the American/Soviet space race up to the first landing of a man on the Moon. It focuses on Sergei Korolev, the Soviet chief rocket designer, and Wernher von Braun, his American counterpart. The series was a joint effort between British, German, American and Russian production teams.
Ernst Stuhlinger was a German-American atomic, electrical, and rocket scientist. After being brought to the United States as part of Operation Paperclip, he developed guidance systems with Wernher von Braun's team for the US Army, and later was a scientist with NASA. He was also instrumental in the development of the ion engine for long-endurance space flight, and a wide variety of scientific experiments.
The Redstone Test Stand or Interim Test Stand was used to develop and test fire the Redstone missile, Jupiter-C sounding rocket, Juno I launch vehicle and Mercury-Redstone launch vehicle. It was declared an Alabama Historic Civil Engineering Landmark in 1979 and a National Historic Landmark in 1985. It is located at NASA's George C. Marshall Space Flight Center (MSFC) in Huntsville, Alabama on the Redstone Arsenal, designated Building 4665. The Redstone missile was the first missile to detonate a nuclear weapon. Jupiter-C launched to test components for the Jupiter missile. Juno I put the first American satellite Explorer 1 into orbit. Mercury Redstone carried the first American astronaut Alan Shepard into space. The Redstone earned the name "Old Reliable" because of this facility and the improvements it made possible.
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.
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 Redstone family of rockets consisted of a number of American ballistic missiles, sounding rockets and expendable launch vehicles operational during the 1950s and 1960s. The first member of the Redstone family was the PGM-11 Redstone missile, from which all subsequent variations of the Redstone were derived. The Juno 1 version of the Redstone launched Explorer 1, the first U.S. orbital satellite in 1958 and the Mercury-Redstone variation carried the first two U.S. astronauts into space in 1961. The rocket was named for the Redstone Arsenal in Huntsville, Alabama where it was developed.
Hydyne is a mixture of 60% unsymmetrical dimethylhydrazine (UDMH) and 40% diethylenetriamine (DETA), developed in 1957 at Rocketdyne for use in liquid-fuel rockets. Hydyne was used as the fuel for the first stage of the Juno I rocket that launched Explorer 1, the first successful satellite launch conducted by the United States.
The National Aeronautics and Space Administration (NASA) was created in 1958 from the National Advisory Committee for Aeronautics (NACA), and other related organizations, as the result of the Space Race between the United States and the Soviet Union in the 1950s.
