Cancelled Space Shuttle Missions
During NASA's Space Shuttle program, several missions were canceled. Many were canceled as a result of the ''Challenger'' and the ''Columbia'' disasters or due to delays in the development of the shuttle. Others were canceled because of changes in payload and mission requirements. Canceled due to the late development of the Space Shuttle In 1972, NASA's planners had projected for 570 Space Shuttle missions between 1980 and 1991. Later, this estimate was lowered to 487 launches between 1980 and 1992. The details of the first 23 projected missions, listed in the third edition of ''Manned Spaceflight'' ( Reginald Turnill, 1978) and the first edition of the ''STS Flight Assignment Baseline'', an internal NASA document published in October 1977, are presented below. Later in the development process, NASA suggested using the first manned Space Shuttle mission, STS-1, as a sub-orbital test of the Return to Launch Site (RTLS) flight profile devised for emergency abort scenarios. ...

NASA
The National Aeronautics and Space Administration (NASA ) is an independent agencies of the United States government, independent agency of the US federal government responsible for the civil List of government space agencies, space program, aeronautics research, and outer space, space research. NASA was National Aeronautics and Space Act, established in 1958, succeeding the National Advisory Committee for Aeronautics (NACA), to give the U.S. space development effort a distinctly civilian orientation, emphasizing peaceful applications in space science. NASA has since led most American space exploration, including Project Mercury, Project Gemini, the 1968-1972 Apollo program, Apollo Moon landing missions, the Skylab space station, and the Space Shuttle. NASA supports the International Space Station and oversees the development of the Orion (spacecraft), Orion spacecraft and the Space Launch System for the crewed lunar Artemis program, Commercial Crew Program, Commercial Crew ...

Joe Engle
Joe Henry Engle (born August 26, 1932) is an American pilot, aeronautical engineer and former NASA astronaut. He was the commander of two Space Shuttle missions including STS-2 in 1981, the program's second orbital flight. He also flew three flights in the Shuttle program's 1977 Approach and Landing Tests. Engle is one of twelve pilots who flew the North American X-15, an experimental spaceplane jointly operated by the Air Force and NASA. As an X-15 pilot, Engle made three flights above 50 miles, thus qualifying for astronaut wings under the American convention for the boundary of space. In 1966 he was selected for NASA's fifth Astronaut Group, joining the Apollo program. He was the backup Lunar Module Pilot (LMP) for Apollo 14 and originally scheduled as LMP for Apollo 17. However, cancellation of later flights prompted NASA to select geologist-astronaut Harrison Schmitt as LMP, displacing Engle. Engle is an experienced spaceplane operator and the last living X-15 pilot. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anik (satellite)
The Anik satellites are a series of geostationary communications satellites launched for Telesat Canada for television, voice and data in Canada and other parts of the world, from 1972 through 2013. Some of the later satellites in the series remain operational in orbit, while others have been retired to a graveyard orbit. The naming of the satellite was determined by a national contest, and was won by Julie-Frances Czapla of Saint-Léonard, Québec. In Inuktitut, ''Anik'' means "little brother". Satellites Anik A The Anik A satellites were the world's first national domestic satellites. (Prior to Anik A1's launch, all geosynchronous communications satellites were transcontinental, i.e. Intelsat I and others.) The Anik A fleet of three satellites gave CBC the ability to reach the Canadian North for the first time. Each of the satellites was equipped with 12 C-band transponders, and thus had the capacity for 12 colour television channels. Three channels were allocate ...

GOES 4
GOES-4, known as GOES-D before becoming operational, was a geostationary weather satellite which was operated by the United States National Oceanic and Atmospheric Administration as part of the Geostationary Operational Environmental Satellite system. Launched in 1980, it was used for weather forecasting in the United States, and later in Europe. Following its retirement it became the first satellite to be sent into a graveyard orbit. Limited lifespan GOES-4 was built by Hughes Space and Communications, and was based around the HS-371 satellite bus. At launch it had a mass of , with an expected operational lifespan of around seven years. It was the first HS-371 based GOES satellite. Launch and orbit GOES-D was launched using a Delta 3914 carrier rocket flying from Launch Complex 17A at the Cape Canaveral Air Force Station. The launch occurred at 22:27 GMT on 9 September 1980. The launch successfully placed GOES-D into a geosynchronous transfer orbit, from which it raised itself ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
STS-6
STS-6 was the sixth NASA Space Shuttle mission and the maiden flight of the . Launched from Kennedy Space Center on April 4, 1983, the mission deployed the first Tracking and Data Relay Satellite, TDRS-1, into orbit, before landing at Edwards Air Force Base on April 9, 1983. STS-6 was the first Space Shuttle mission during which a spacewalk was conducted, and hence was the first in which the Extravehicular Mobility Unit (EMU) was used. Crew STS-6 was the last shuttle mission with a four-person crew until STS-135, the final shuttle mission, which launched on July 8, 2011. Commander Paul Weitz had previously served as Pilot on the first Skylab crewed mission (Skylab-2), where he lived and worked in Skylab for nearly a month from May to June 1973. After Skylab, Weitz became the Deputy Chief of the Astronaut Office under Chief Astronaut John Young. Bobko originally became an astronaut for the Air Force's Manned Orbiting Laboratory (MOL) program but later joined NASA in ...

Satellite Business Systems
Satellite Business Systems (SBS) was a company founded by IBM, Aetna, COMSAT (and later wholly purchased by IBM and then subsequently sold to MCI), that provided private professional satellite communications through its SBS fleet of FSS geosynchronous satellites, and was the first company to do so. SBS was founded on December 15, 1975 by the aforementioned companies with the goal of providing a digital satellite communications network for business and other professional clients. History In late 1970, MCI Communications created a subsidiary company named MCI Satellite, Inc. The idea was that satellites could provide 'long distance' service from anywhere to anywhere without having to build thousands of miles of terrestrial network facilities. In early 1971, MCI and Lockheed Missiles and Space Company created a joint venture named MCI Lockheed Satellite Corp. which was the first company to request FCC authorization as a Specialized Common Carrier using satellite based communic ...

TDRS-1
TDRS-1, known before launch as TDRS-A, was an American communications satellite, operated by NASA as part of the Tracking and Data Relay Satellite System. It was constructed by TRW and launched by on its maiden flight, STS-6. History While on the pad, problems were detected with ''Challenger'' main engines and repairs were begun. During this time, a severe storm caused contamination of TDRS-1 while it was in the Payload Change-out Room on the Rotating Service Structure at the launch pad. Consequently, the satellite had to be taken back to its checkout facility, where it was cleaned and rechecked. ''Challenger'' finally lifted off from Launch Complex 39A of the Kennedy Space Center at 18:30:00 UTC on 4 April 1983. Operations Following deployment from ''Challenger'', TDRS-1 was to be raised to its operational geosynchronous orbit by means of an Inertial Upper Stage, which consisted of two solid rocket motors, the first used to raise the orbit's apogee, the second its perigee ...

STS-41-C
STS-41-C (formerly STS-13) was NASA's eleventh Space Shuttle mission, and the fifth mission of Space Shuttle ''Challenger''. The launch, which took place on April 6, 1984, marked the first direct ascent trajectory for a Space Shuttle mission. During the mission, ''Challenger''s crew captured and repaired the malfunctioning Solar Maximum Mission ("Solar Max") satellite, and deployed the Long Duration Exposure Facility (LDEF) experimental apparatus. STS-41-C was extended one day due to problems capturing the Solar Max satellite, and the landing on April 13, 1984, took place at Edwards Air Force Base, instead of at Kennedy Space Center as had been planned. The flight was originally numbered STS-13.James D. A. van Hoften NASA Johnson Space Center Oral History Project. December 5, 2007, Ret ...

Space Shuttle Challenger
Space Shuttle ''Challenger'' (OV-099) was a Space Shuttle orbiter manufactured by Rockwell International and operated by NASA. Named after the commanding ship of a nineteenth-century scientific expedition that traveled the world, ''Challenger'' was the second Space Shuttle orbiter to fly into space after '' Columbia'', and launched on its maiden flight in April 1983. It was destroyed in January 1986 soon after launch in an accident that killed all seven crewmembers aboard. Initially manufactured as a test article not intended for spaceflight, it was utilized for ground testing of the Space Shuttle orbiter's structural design. However, after NASA found that their original plan to upgrade '' Enterprise'' for spaceflight would be more expensive than upgrading ''Challenger'', the orbiter was pressed into operational service in the Space Shuttle program. Lessons learned from the first orbital flights of ''Columbia'' led to ''Challenger''s design possessing fewer thermal protecti ...

Long Duration Exposure Facility
NASA's Long Duration Exposure Facility, or LDEF (pronounced "eldef"), was a school bus-sized cylindrical facility designed to provide long-term experimental data on the outer space environment and its effects on space systems, materials, operations and selected spores' survival. It was placed in low Earth orbit by in April 1984. The original plan called for the LDEF to be retrieved in March 1985, but after a series of delays it was eventually returned to Earth by in January 1990. It successfully carried science and technology experiments for about 5.7 years that have revealed a broad and detailed collection of space environmental data. LDEF's 69 months in space provided scientific data on the long-term effects of space exposure on materials, components and systems that has benefited NASA spacecraft designers to this day. History Researchers identified the potential of the planned Space Shuttle to deliver a payload to space, leave it there for a long-term exposure to the harsh o ...
