U.S. Army Redstone Test Center

The George C. Marshall Space Flight Center (MSFC), located in Redstone Arsenal, Alabama (Huntsville postal address), 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. The center contains the Huntsville Operations Support Center (HOSC), also known as the International Space Station Payload Operations Center. This facility supports ISS launch, payload, and experiment activities at the Kennedy Space Center. The HOSC also monitors rocket launches from Cape Canaveral Space Force Station when a Marshall Center payload is on board.

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 Interim Test Stand was built in 1953 by Dr. Wernher von Braun's team for a mere US$25,000 (equivalent to $273,445 in 2022) out of materials salvaged from the Redstone Arsenal. In 1957 the permanent test facility called the Static Test Tower was finally finished, but the Army decided to continue operations at the Interim Test Stand rather than move. From 1953 to 1961, 362 static rocket tests were conducted there, including 200 that led directly to improvements in the Redstone rocket for the Mercury manned flight program. Adapted over the years, it never experienced the growth in size and cost that typified test stands in general, remaining a testament to the engineering ingenuity of the rocket pioneers.

Saturn V dynamic test stand, also known as dynamic structural test facility, at the George C. Marshall Space Flight Center in Huntsville, Alabama is the test stand used for testing of the Saturn V rocket and the Space Shuttle prior to the vehicles' first flights. Designated building 4550, it stands 363 feet (111 m) tall and is 98 feet (30 m) square. Its central bay has maximum dimensions of 74 by 74 feet (23 m × 23 m), and it is topped by a derrick capable of moving 200-ton objects in a 70-foot (21 m) radius. An elevator provides access to 15 levels in the structure, and a cable tunnel connects the building to control facilities in the space center's East Test Area.NASA built the test stand in 1964 to conduct mechanical and vibrational tests on the fully assembled Saturn V rocket. Major problems capable of causing failure of the vehicle were discovered and corrected here. The new building was so tall that in 1966 when the Saturn V first stage was entering, an observer noted, "Fog and clouds hovered around the top of the 360 foot (110 m) tall test stand most of the day while the 300,000 pounds (140,000 kg) stage was being lifted from its transporter into place inside the stand, said to be the tallest building in Alabama." The stand was used to test how spacecraft behaved when put under vibrating and bending stresses, and to test the connections between major stages of the craft.It was declared a National Historic Landmark in 1985 for its role in the Saturn V program.In addition to the Saturn V dynamic test vehicle, designated SA-500D, two Space Shuttle test vehicles, Pathfinder and Enterprise, were also tested in this facility.

The Neutral Buoyancy Simulator was a neutral buoyancy pool located at NASA's George C. Marshall Space Flight Center (MSFC). Engineers and astronauts developed hardware and practiced procedures in this tank from its completion in 1968 through its decommissioning in 1997. Marshall recognized the need for underwater simulations of extra-vehicular activities (EVAs) and developed three successively larger tanks for the purpose. The Neutral Buoyancy Simulator contributed significantly to the American crewed space program. Skylab, the Space Shuttle, Hubble Space Telescope, and the International Space Station have all benefited from the Neutral Buoyancy Simulator. Until Johnson Space Center constructed the Weightless Environment Test Facility in the mid-1970s, MSFC had the only NASA-owned test facility that allowed engineers and astronauts to become familiar with the dynamics of body motion under weightless conditions.: 1968-03 p.39 The water within the simulator was temperature controlled, continuously recirculated and filtered. Special systems were integrated into the tank for underwater audio and video, pressure-suit environmental control and emergency rescue and treatment. Life support was simultaneously provided by these systems for up to four pressure-suited subjects. Additional systems included data acquisition and recording, underwater lighting, special underwater pneumatic and electrical power operations of motor, valves, controls, and indicators that required for high fidelity and functional engineering mockups and trainers.

The Redstone Technical Test Center (RTTC) was one of the eight test centers that comprise the Developmental Test Command of the United States Army Test and Evaluation Command. RTTC conducted flight-testing of small rockets and guided missiles, and performed life cycle testing for weapon components. It occupied over 265 buildings and 14,000 acres (57 km2) of Redstone Arsenal, near Huntsville, Alabama. In October 2010, as part of the Base Reallocation and Closure (BRAC) process, RTTC was combined with the Aviation Technical Test Center from Fort Rucker to form the U.S. Army Redstone Test Center.

The Planetary Missions Program Office is a division of NASA headquartered at the Marshall Space Flight Center, formed by the agency's Science Mission Directorate (SMD). Succeeding the Discovery and New Frontiers Program Office, it was established in 2014 to manage the Discovery and New Frontiers programs of low and medium-cost missions by third-party institutions, and the Solar System Exploration program of NASA-led missions that focus on prioritized planetary science objectives. The Discovery and New Frontiers programs were established in 1992 and 2001 respectively, and have launched fourteen primary missions together, along with two missions launched under the administration of the Planetary Missions Program Office. The Solar System Exploration Program was established alongside the office, with three missions planned for launch under the new program.

The Propulsion and Structural Test Facility, also known as Building 4572 and the Static Test Stand, is a rocket testing facility of the George C. Marshall Space Flight Center in Huntsville, Alabama. Built in 1957, it was the site where the first single-stage rockets with multiple engines were tested. It was declared a National Historic Landmark in 1985 for its role in the development of the United States space program.

The U.S. Army Combat Capabilities Development Command Aviation & Missile Center (AvMC), formerly known as the U.S. Army Aviation and Missile Research, Development and Engineering Center (AMRDEC), a part of the U.S. Army Research, Development, and Engineering Command (RDECOM) — now DEVCOM, is primarily a civilian organization tasked to provide research, development and engineering technology and services to support U.S. Army aviation and missile platforms. AvMC conducts research, promotes development, engineering and simulation laboratories and facilities used to develop and improve aviation and missile components, subsystems and systems. AvMC's offices are located at the Redstone Arsenal Army post in Madison County, Alabama.AvMC employs over 11,000 government, civilian employees and contractors.

The Redstone Arsenal cemeteries are a grouping of historic cemeteries on the Redstone Arsenal property in Madison County, Alabama, all administered by the United States Army. Prior to Army acquisition of the land in 1941 through 1942, the area was occupied by several loosely-knit rural communities which included at least 46 individual cemeteries.The historic cemeteries that remain include plantation family plots, probable slave cemeteries, and Reconstruction era through early 20th century community cemeteries. Following the displacement of roughly 550 families by the acquisition of over 40,000 acres (160 km2) of land including both historic cemeteries and archaeological sites with the potential for containing human burials, the Army initially considered establishing a new cemetery on the northeast end of the installation and moving all of the historic interments to this new location. This plan was never implemented.After the United States Congress passed the National Cemetery Act in 1973, discussion of establishing a National Cemetery at Redstone Arsenal was revived since the Mobile National Cemetery, the only other National Cemetery in Alabama at the time, was out of space, partially due to the dramatic casualty load from the Vietnam War. After consulting with the Army Memorial Affairs Agency, however, it was decided that there was no need to expand the current national cemetery program. There was no discussion at this time of relocating any of the cemeteries on the installation.The 46 cemeteries continue to be maintained in situ as long as the Army owns the land, per the Army's responsibility according to Army regulations.

Redstone Arsenal is a United States Army base adjacent to Huntsville, Alabama in the Wheeler National Wildlife Refuge. It is a census-designated place in Madison County, Alabama, United States and 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 Arsenal today contains a government and contractor workforce that averages 36,000 to 40,000 personnel daily. The base has benefited from decisions by the Defense Base Realignment and Closure Commission and has a residential population of 837 as of 2020.Established during World War II as a chemical manufacturing facility, in the immediate post-war era the Arsenal was used for research and development by German rocket scientists who were brought to the U.S. as part of Operation Paperclip. The team first worked on ballistic missiles, starting with derivatives of the V-2 rocket, before moving on to a series of ever larger designs. In 1956 the Army was relieved of most of its ballistic missiles in favor of similar weapons operated by the US Air Force. The German design team was spun off to become part of the newly founded NASA. The Cold War had moved to space, and the US intended to compete with the Soviet Union there and across the globe. The Arsenal served as the primary site for space launch vehicle design and testing into the 1960s.

Redstone Army Airfield or Redstone AAF (IATA: HUA, ICAO: KHUA, FAA LID: HUA) is a military airport located at Redstone Arsenal, six miles (10 km) southwest of the city of Huntsville in Madison County, Alabama, United States. The airfield was originally constructed for munitions testing for the U.S. Army and the U.S. Army Air Forces through the 6th AAF Base Unit (Proving Ground Detachment). It is currently used to support the U.S. Army Aviation and Missile Command, NASA, and other U.S. government aviation and space activities.
