STS-39
STS-39 was the twelfth mission of the NASA Space Shuttle ''Discovery'', and the 40th orbital shuttle mission overall. The primary purpose of the mission was to conduct a variety of payload experiments for the U.S. Department of Defense (DoD). Crew Crew seating arrangements Mission highlights Launch was originally scheduled for March 9, 1991, but during processing work at Pad LC-39A, significant cracks were found on all four lug hinges on the two external tank umbilical door drive mechanisms. NASA managers opted to roll back the vehicle to the Vehicle Assembly Building (VAB) on March 7, 1991, and then to Orbiter Processing Facility (OPF) for repair. The faulty hinges were replaced with units taken from orbiter ''Columbia'', and reinforced. ''Discovery'' was returned to the pad on April 1, 1991, and the launch was rescheduled for April 23. The mission was again postponed when, during prelaunch external tank loading, a transducer on high-pressure oxidizer turbopump f ...

Shuttle Pallet Satellite
The shuttle pallet satellite was a satellite bus designed to be deployed and then retrieved for return to Earth on NASA's Space Shuttle. It carried a variety of payloads both scientific and military in nature. It was made by Messerschmitt-Bölkow-Blohm and first flew in 1983. It was carried for the first time during the STS-7 mission and called SPAS-01 carrying 10 payloads. It flew again on the STS-39 mission in 1991 called IBSS-SPAS (Infrared Background Signature Survey – Shuttle Palette Satellite) for the DOD testing various ballistic missile detection sensors. SPAS flew for the third time with the STS-51 mission in 1991 called ORFEUS-SPAS (Orbiting & Retrievable Far & Extreme UV Spectrometer – Shuttle Palette Satellite) with ultraviolet instruments. ORFEUS-SPAS was flown again on the STS-80 mission. SPAS was flown for the second to last time with the CRISTA-SPAS (Cryogenic Infrared Spectrometers & Telescopes for the Atmosphere – Shuttle Palette Satellit ...

Space Shuttle Discovery
Space Shuttle ''Discovery'' (Orbiter Vehicle Designation: OV-103) is one of the orbiters from NASA's Space Shuttle program and the third of five fully operational orbiters to be built. Its first mission, STS-41-D, flew from August 30 to September 5, 1984. Over 27 years of service it launched and landed 39 times, aggregating more spaceflights than any other spacecraft to date. The Space Shuttle launch vehicle has three main components: the Space Shuttle orbiter, a single-use central fuel tank, and two reusable solid rocket boosters. Nearly 25,000 heat-resistant tiles cover the orbiter to protect it from high temperatures on re-entry. ''Discovery'' became the third operational orbiter to enter service, preceded by '' Columbia'' and '' Challenger''. It embarked on its final mission, STS-133, on February 24, 2011, and touched down for the last time at Kennedy Space Center on March 9, having spent a cumulative total of nearly a full year in space. ''Discovery'' performed both ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
AFP-675
AFP-675 (Air Force Program-675) was a Space Shuttle experiment package that was carried into orbit on ''Discovery'' as part of STS-39. AFP-675 consisted of six experiment packages mounted on a pallet in the ''Discovery's'' cargo bay. The total weight of the package was 5,080 kilograms (11,200 lb). The objectives of the project were: # To obtain data in several wavelength regions to support the development of Department of Defense (DOD) systems # To validate technologies for DOD applications # To validate the use of man as an autonomous experimenter in space # To demonstrate the cost effectiveness of performing DOD experiments on reusable systems. The experiments Cryogenic Infrared Radiance Instrumentation for Shuttle The Cryogenic Infrared Radiance Instrumentation for Shuttle (CIRRIS 1A) experiment was designed to measure the spectral, spatial, and temporal properties of the Earth's limb (edge). The primary instruments in this experiment were a Michelson spatial interfer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Critical Ionization Velocity
Critical ionization velocity (CIV), or critical velocity (CV), is the relative velocity between a neutral gas and plasma (an ionized gas), at which the neutral gas will start to ionize. If more energy is supplied, the velocity of the atoms or molecules will not exceed the critical ionization velocity until the gas becomes almost fully ionized. The phenomenon was predicted by Swedish engineer and plasma scientist, Hannes Alfvén, in connection with his model on the origin of the Solar System (1942). At the time, no known mechanism was available to explain the phenomenon, but the theory was subsequently demonstrated in the laboratory.U.V. Fahleson, "Experiments with plasma moving through neutral gas", Phys. Fluids, 4 123 (1961) Subsequent research by Brenning and Axnäs (1988) have suggested that a ''lower hybrid'' plasma instability is involved in transferring energy from the larger ions to electrons so that they have sufficient energy to ionize. Application of the theory to astron ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
STS-37
STS-37, the thirty-ninth NASA Space Shuttle mission and the eighth flight of the Space Shuttle Atlantis, Space Shuttle ''Atlantis'', was a six-day mission with the primary objective of launching the Compton Gamma Ray Observatory (CGRO), the second of the Great Observatories program which included the visible-spectrum Hubble Space Telescope (HST), the Chandra X-ray Observatory (CXO) and the infrared Spitzer Space Telescope. The mission also featured two Extravehicular activity, spacewalks, the first since 1985.

STS-40
STS-40, the eleventh launch of Space Shuttle ''Columbia'', was a nine-day mission in June 1991. It carried the Spacelab module for Spacelab Life Sciences 1 (SLS-1), the fifth Spacelab mission and the first dedicated solely to biology. STS-40 was the first spaceflight that included three women crew members. Crew Backup crew Crew seating arrangements Mission highlights Launch originally set for May 22, 1991. Mission postponed less than 48 hours before launch when it became known that a leaking liquid hydrogen transducer in orbiter main propulsion system which was removed and replaced during leak testing in 1990, had failed an analysis by vendor. Engineers feared that one or more of the nine liquid hydrogen and liquid oxygen transducers protruding into fuel and oxidizer lines could break off and be ingested by the engine turbopumps, causing engine failure. In addition, one of orbiter five general purpose computers failed completely, along with one of the multiple ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Space Shuttle Seating Plan
Space is the boundless three-dimensional extent in which objects and events have relative position and direction. In classical physics, physical space is often conceived in three linear dimensions, although modern physicists usually consider it, with time, to be part of a boundless four-dimensional continuum known as spacetime. The concept of space is considered to be of fundamental importance to an understanding of the physical universe. However, disagreement continues between philosophers over whether it is itself an entity, a relationship between entities, or part of a conceptual framework. Debates concerning the nature, essence and the mode of existence of space date back to antiquity; namely, to treatises like the ''Timaeus'' of Plato, or Socrates in his reflections on what the Greeks called ''khôra'' (i.e. "space"), or in the ''Physics'' of Aristotle (Book IV, Delta) in the definition of ''topos'' (i.e. place), or in the later "geometrical conception of place" as "space ...

Space Transportation System
The Space Transportation System (STS), also known internally to NASA as the Integrated Program Plan (IPP), was a proposed system of reusable crewed space vehicles envisioned in 1969 to support extended operations beyond the Apollo program. (NASA appropriated the name for its Space Shuttle Program, the only component of the proposal to survive Congressional funding approval). The purpose of the system was two-fold: to reduce the cost of spaceflight by replacing the current method of launching capsules on expendable rockets with reusable spacecraft; and to support ambitious follow-on programs including permanent orbiting space stations around Earth and the Moon, and a human landing mission to Mars. In February 1969, President Richard Nixon appointed a Space Task Group headed by Vice President Spiro Agnew to recommend human space projects beyond Apollo. The group responded in September with the outline of the STS, and three different program levels of effort culminating with a ...
