Kennedy Space Center
The John F. Kennedy Space Center (KSC, originally known as the NASA Launch Operations Center), located on Merritt Island, Florida, is one of the National Aeronautics and Space Administration's (NASA) ten field centers. Since December 1968, KSC has been NASA's primary launch center of human spaceflight. Launch operations for the Apollo, Skylab and Space Shuttle programs were carried out from Kennedy Space Center Launch Complex 39 and managed by KSC. Located on the east coast of Florida, KSC is adjacent to Cape Canaveral Space Force Station (CCSFS). The management of the two entities work very closely together, share resources and operate facilities on each other's property. Though the first Apollo flights and all Project Mercury and Project Gemini flights took off from the then-Cape Canaveral Air Force Station, the launches were managed by KSC and its previous organization, the Launch Operations Directorate. Starting with the fourth Gemini mission, the NASA launch contro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dream Chaser
Dream Chaser is an American reusable lifting-body spaceplane being developed by Sierra Nevada Corporation (SNC) Space Systems. Originally intended as a crewed vehicle, the Dream Chaser Space System is set to be produced after the cargo variant, Dream Chaser Cargo System, is operational.

X-57
The NASA X-57 Maxwell is an experimental aircraft being developed by NASA, intended to demonstrate technology to reduce fuel use, emissions, and noise. The first flight of the X-57 is scheduled to take place in 2023. Development The experiment involves replacing the wings on a twin-engined Italian-built Tecnam P2006T (a conventional four-seater light aircraft) with distributed electric propulsion (DEP) wings each containing electrically driven propellers. Test flights were initially planned to commence in 2017. The first test phase uses an 18-engine truck-mounted wing. The second phase will install the cruise propellers and motors on a standard P2006T for ground- and flight-test experience. Phase 3 tests will involve the high-lift DEP wing and demonstrate increased high-speed cruise efficiency. The leading-edge nacelles will be fitted, but the high-lift propellers, motors and controllers will not be installed. Phase 4 adds the DEP motors and folding propellers to demonstrate ...

X-43A
The NASA X-43 was an experimental unmanned hypersonic aircraft with multiple planned scale variations meant to test various aspects of hypersonic flight. It was part of the X-plane series and specifically of NASA's Hyper-X program. It set several airspeed records for jet aircraft. The X-43 is the fastest jet-powered aircraft on record at approximately Mach 9.6.Thompson, Elvia, Keith Henry and Leslie Williams"Faster Than a Speeding Bullet: Guinness Recognizes NASA Scramjet."''NASA.'' Retrieved: August 1, 2011. A winged booster rocket with the X-43 placed on top, called a "stack", was drop launched from a Boeing B-52 Stratofortress. After the booster rocket (a modified first stage of the Pegasus rocket) brought the stack to the target speed and altitude, it was discarded, and the X-43 flew free using its own engine, a scramjet. The first plane in the series, the X-43A, was a single-use vehicle, of which three were built. The first X-43A was destroyed after malfunc ...

Hypersonic
In aerodynamics, a hypersonic speed is one that exceeds 5 times the speed of sound, often stated as starting at speeds of Mach 5 and above. The precise Mach number at which a craft can be said to be flying at hypersonic speed varies, since individual physical changes in the airflow (like molecular dissociation and ionization) occur at different speeds; these effects collectively become important around Mach 5-10. The hypersonic regime can also be alternatively defined as speeds where specific heat capacity changes with the temperature of the flow as kinetic energy of the moving object is converted into heat. Characteristics of flow While the definition of hypersonic flow can be quite vague and is generally debatable (especially due to the absence of discontinuity between supersonic and hypersonic flows), a hypersonic flow may be characterized by certain physical phenomena that can no longer be analytically discounted as in supersonic flow. The peculiarity in hypersonic flows ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
North American X-15
The North American X-15 is a hypersonic rocket-powered aircraft. It was operated by the United States Air Force and the National Aeronautics and Space Administration as part of the X-plane series of experimental aircraft. The X-15 set speed and altitude records in the 1960s, reaching the edge of outer space and returning with valuable data used in aircraft and spacecraft design. The X-15's highest speed, , was achieved on 3October 1967, when William J. Knight flew at Mach6.7 at an altitude of , or 19.34miles. This set the official world record for the highest speed ever recorded by a crewed, powered aircraft, which remains unbroken. During the X-15 program, 12pilots flew a combined 199flights. Of these, 8pilots flew a combined 13flights which met the Air Force spaceflight criterion by exceeding the altitude of , thus qualifying these pilots as being astronauts; of those 13flights, two (flown by the same civilian pilot) met the FAI definition () of outer space. The 5A ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Supersonic
Supersonic speed is the speed of an object that exceeds the speed of sound ( Mach 1). For objects traveling in dry air of a temperature of 20 °C (68 °F) at sea level, this speed is approximately . Speeds greater than five times the speed of sound (Mach 5) are often referred to as hypersonic. Flights during which only some parts of the air surrounding an object, such as the ends of rotor blades, reach supersonic speeds are called transonic. This occurs typically somewhere between Mach 0.8 and Mach 1.2. Sounds are traveling vibrations in the form of pressure waves in an elastic medium. Objects move at supersonic speed when the objects move faster than the speed at which sound propagates through the medium. In gases, sound travels longitudinally at different speeds, mostly depending on the molecular mass and temperature of the gas, and pressure has little effect. Since air temperature and composition varies significantly with altitude, the speed of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
