Altair 2
The Constellation Program was NASA's planned future human spaceflight program between 2005 and 2009, which aimed to develop a new crewed spacecraft ( Orion) and a pair of launchers (Ares I and Ares V) to continue servicing the International Space Station and return to the Moon. As of 2009, a single uncrewed suborbital launch test (Ares I-X) had been flown, with crewed missions anticipated to begin between 2014 (when an uncrewed mission was indeed launched) and 2017-2019 (according to the independent Augustine Commission). On February 1, 2010, President Obama announced that he intended to cancel the program with the U.S. 2011 fiscal year budget. A revised proposal in April confirmed that the Orion spacecraft would be retained for future missions beyond low Earth orbit, with the Ares launchers redeveloped into the Space Launch System. However, the Constellation Program itself was cancelled, with low Earth orbit operations transferred to the Commercial Crew Development program, whi ...

J-2 (rocket Engine)
The J-2 is a liquid-fuel cryogenic rocket engine used on NASA's Saturn IB and Saturn V launch vehicles. Built in the U.S. by Rocketdyne, the J-2 burned cryogenic liquid hydrogen (LH2) and liquid oxygen (LOX) propellants, with each engine producing of thrust in vacuum. The engine's preliminary design dates back to recommendations of the 1959 Silverstein Committee. Rocketdyne won approval to develop the J-2 in June 1960 and the first flight, AS-201, occurred on 26 February 1966. The J-2 underwent several minor upgrades over its operational history to improve the engine's performance, with two major upgrade programs, the de Laval nozzle-type J-2S and aerospike-type J-2T, which were cancelled after the conclusion of the Apollo program. The engine produced a specific impulse (''I''sp) of in a vacuum (or at sea level) and had a mass of approximately . Five J-2 engines were used on the Saturn V's S-II second stage, and one J-2 was used on the S-IVB upper stage used on both the Satu ...

Delta IV Heavy
The Delta IV Heavy (Delta 9250H) is an Evolved Expendable Launch Vehicle, expendable heavy-lift launch vehicle, the largest type of the Delta IV family. It is the world's third highest-capacity launch vehicle in operation, behind NASA's Space Launch System and SpaceX's Falcon Heavy and closely followed by China Aerospace Science and Technology Corporation, CASC's Long March 5. It is manufactured by United Launch Alliance (ULA) and was first launched in 2004. ULA will retire the Delta IV Heavy in 2024. , two flights remain. The Delta IV Heavy consists of a central Common Booster Core (CBC), with two additional CBCs as liquid rocket boosters instead of the Graphite-Epoxy Motor, GEM-60 solid rocket motors used by the Delta IV Medium+ versions. At lift off, all three cores operate at full thrust, and 44 seconds later the center core throttles down to 55% to conserve fuel until booster separation. The boosters burn out at 242 seconds after launch and are separated as the core booster ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Exploration Flight Test 1
Exploration Flight Test-1 or EFT-1 (previously known as Orion Flight Test 1 or OFT-1) was the first test flight of the crew module portion of the Orion Multi-Purpose Crew Vehicle. Without a crew, it was launched on December 5, 2014, at 12:05 UTC (7:05 am EST), by a Delta IV Heavy rocket from Space Launch Complex 37B at Cape Canaveral Space Force Station. The mission was a four-hour, two-orbit test of the Orion crew module featuring a high apogee on the second orbit and concluding with a high-energy reentry at around . This mission design corresponds to the Apollo 2/3 missions of 1966, which validated the Apollo flight control system and heat shield at re-entry conditions planned for the return from lunar missions. NASA heavily promoted the mission, collaborating with ''Sesame Street'' and its characters to educate children about the flight test and the Orion spacecraft. Objectives The flight was intended to test various Orion systems, including separation events, av ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
White Sands Missile Range
White Sands Missile Range (WSMR) is a United States Army military testing area and firing range located in the US state of New Mexico. The range was originally established as the White Sands Proving Ground on 9July 1945. White Sands National Park is located within the range. Significant events *The first atomic bomb (code named Trinity) was test detonated at Trinity Site near the northern boundary of the range on 16 July 1945, seven days after the White Sands Proving Ground was established. *After the conclusion of World War II, 100 long-range German V-2 rockets that were captured by U.S. military troops were brought to WSMR. Of these, 67 were test-fired between 1946 and 1951 from the White Sands V-2 Launching Site. (This was followed by the testing of American rockets, which continues to this day, along with testing other technologies.) *NASA's Space Shuttle Columbia landed on the Northrop Strip at WSMR on 30 March 1982 as the conclusion to mission STS-3. This was the only ti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Langley Research Center
The Langley Research Center (LaRC or NASA Langley), located in Hampton, Virginia, United States of America, is the oldest of NASA's field centers. It directly borders Langley Air Force Base and the Back River on the Chesapeake Bay. LaRC has focused primarily on aeronautical research, but has also tested space hardware such as the Apollo Lunar Module. In addition, many of the earliest high-profile space missions were planned and designed on-site. Langley was also considered a potential site for NASA's Manned Spacecraft Center prior to the eventual selection of Houston, Texas. Established in 1917 by the National Advisory Committee for Aeronautics (NACA), the research center devotes two-thirds of its programs to aeronautics and the rest to space. LaRC researchers use more than 40 wind tunnels to study and improve aircraft and spacecraft safety, performance, and efficiency. Between 1958 and 1963, when NASA (the successor agency to NACA) started Project Mercury, LaRC served as the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pad Abort-1
Pad Abort 1 (PA-1) was a flight test of the Orion Launch Abort System (LAS). PA-1 was the first test in a sequence of atmospheric flight tests known as Orion Abort Flight Test (AFT). PA-1 tested the basic functionality of the launch abort concept from the pad in its preliminary Orion design configuration. It used the former conformal shape of the LAS adapter. The Flight Test Article (FTA) vehicle differed from production Orion vehicles in a number of ways. For example, the FTA did not have a crew on board, and the avionics were a prototype of what is planned for production Orions. The PA-1 Test took place at the U.S. Army's White Sands Missile Range in New Mexico. Spacecraft location The Orion capsule used in the test is on display at the Virginia Air and Space Center in Hampton, Virginia.

Launch Escape System
A launch escape system (LES) or launch abort system (LAS) is a crew-safety system connected to a space capsule that can be used to quickly separate the capsule from its launch vehicle in case of an emergency requiring the abort of the launch, such as an impending explosion. The LES is typically controlled by a combination of automatic rocket failure detection, and a manual activation for the crew commander's use. The LES may be used while the launch vehicle is still on the launch pad, or during its ascent. Such systems are usually of two types: *A solid-fueled rocket, mounted above the capsule on a tower, which delivers a relatively large thrust for a brief period of time to send the capsule a safe distance away from the launch vehicle, at which point the capsule's parachute recovery system can be used for a safe landing on ground or water. The tower and rocket are jettisoned from the space vehicle in a normal flight at the point where it is either no longer needed, or cannot be e ...

Altair (spacecraft)
The Altair spacecraft, previously known as the Lunar Surface Access Module or LSAM, was the planned lander spacecraft component of NASA's cancelled Constellation program. Astronauts would have used the spacecraft for landings on the Moon, which was intended to begin around 2019. The Altair spacecraft was planned to be used both for lunar sortie and lunar outpost missions. On February 1, 2010, U.S. President Barack Obama announced a proposal to cancel the Constellation program (except the Orion spacecraft), to be replaced with a re-scoped program, effective with the U.S. 2011 fiscal year budget. Name On December 13, 2007, NASA's Lunar Surface Access Module was retitled "Altair", after the 12th brightest star in the northern hemisphere's night sky, Altair in the constellation Aquila. In Latin, means "eagle", providing a connection to the first crewed lunar landing, Apollo 11's ''Eagle''; the name ''Altair'' itself is a latinization of the Arabic , meaning "the eagle," "t ...

Artemis 1
Artemis 1, officially Artemis I and formerly Exploration Mission-1 (EM-1), was an uncrewed Moon-orbiting mission. As the first major spaceflight of NASA's Artemis program, Artemis 1 marked the return of the agency to lunar exploration originally begun as the Apollo program decades earlier. It was the first integrated flight test of the Orion spacecraft and Space Launch System (SLS) rocket. Its main objective was to test the Orion spacecraft, especially its heat shield, in preparation for subsequent Artemis missions. These missions seek to reestablish a human presence on the Moon and demonstrate technologies and business approaches needed for future scientific studies, including exploration of Mars. The Orion spacecraft for Artemis 1 was stacked on October 20, 2021, marking the first time a super-heavy-lift vehicle has been stacked inside NASA's Vehicle Assembly Building (VAB) since the final Saturn V in 1973. On August 17, 2022, the fully stacked vehicle was rolled out fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Launch Complex 39A
Launch Complex 39A (LC-39A) is the first of Launch Complex 39's three launch pads, located at NASA's Kennedy Space Center in Merritt Island, Florida. The pad, along with Launch Complex 39B, were first designed for the Saturn V launch vehicle. Typically used to launch NASA's crewed spaceflight missions since the late 1960s, the pad was leased by SpaceX and has been modified to support their launch vehicles. History Apollo program In 1961, President Kennedy proposed to Congress the goal of landing a man on the Moon by the end of the decade. Congressional approval led to the launch of the Apollo program, which required a massive expansion of NASA operations, including an expansion of launch operations from the Cape to adjacent Merritt Island to the north and west. First, Launch Complex 39C, Launch Complex 39A was designed to handle launches of the Saturn V rocket, the largest and most powerful launch vehicle, which would propel Apollo spacecraft to the Moon.
