Location Of TDRS
In geography, location or place are used to denote a region (point, line, or area) on Earth's surface or elsewhere. The term ''location'' generally implies a higher degree of certainty than ''place'', the latter often indicating an entity with an ambiguous boundary, relying more on human or social attributes of place identity and sense of place than on geometry. Types Locality A locality, settlement, or populated place is likely to have a well-defined name but a boundary that is not well defined varies by context. London, for instance, has a legal boundary, but this is unlikely to completely match with general usage. An area within a town, such as Covent Garden in London, also almost always has some ambiguity as to its extent. In geography, location is considered to be more precise than "place". Relative location A relative location, or situation, is described as a displacement from another site. An example is "3 miles northwest of Seattle". Absolute location An absolute locatio ...

Kennedy Space Center 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. The first launch ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cape Canaveral Air Force Station
Cape Canaveral Space Force Station (CCSFS) is an installation of the United States Space Force's Space Launch Delta 45, located on Cape Canaveral in Brevard County, Florida. Headquartered at the nearby Patrick Space Force Base, the station is the primary launch site for the Space Force's Eastern RangeCAST 1999, p. 1-12. with three launch pads currently active (Space Launch Complexes 37B, 40, and 41). The facility is south-southeast of NASA's Kennedy Space Center on adjacent Merritt Island, with the two linked by bridges and causeways. The Cape Canaveral Space Force Station Skid Strip provides a runway close to the launch complexes for military airlift aircraft delivering heavy and outsized payloads to the Cape. A number of American space exploration pioneers were launched from CCSFS, including the first U.S. Earth satellite (1958), first U.S. astronaut (1961), first U.S. astronaut in orbit (1962), first two-man U.S. spacecraft (1965), first U.S. unmanned lunar lan ...

Atlas II
Atlas II was a member of the Atlas family of launch vehicles, which evolved from the successful Atlas missile program of the 1950s. The Atlas II was a direct evolution of the Atlas I, featuring longer first stage tanks, higher-performing engines, and the option for strap-on solid rocket boosters. It was designed to launch payloads into low earth orbit, geosynchronous transfer orbit or geosynchronous orbit. Sixty-three launches of the Atlas II, IIA and IIAS models were carried out between 1991 and 2004; all sixty-three launches were successes, making the Atlas II a highly reliable space launch system. The Atlas line was continued by the Atlas III, used between 2000 and 2005, and the Atlas V which is still in use. Background In May 1988, the US Air Force chose General Dynamics (now Lockheed Martin) to develop the Atlas II vehicle, primarily to launch Defense Satellite Communications System payloads under the Medium Launch Vehicle II (MLV-II) program. Additional commercial and U.S. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
TDRS-8
TDRS-8, known before launch as TDRS-H, is an American communications satellite, of second generation, which is operated by NASA as part of the Tracking and Data Relay Satellite System. It was constructed by Boeing is based on the BSS-601 satellite bus. Launch Its launch was contracted by International Launch Services, using an Atlas IIA launch vehicle. The launch occurred on 30 June 2000, at 12:56:00 UTC from Launch Complex 36A at the Cape Canaveral Air Force Station. It was the first Tracking and Data Relay Satellite, of second generation, to be launched. Due to a malfunction of the multiple-access phased array antenna the spacecraft did not provide the expected level of performance for eighteen of the communications services that it was to provide. The same problem was found and corrected on the TDRS-9 and TDRS-10 satellites prior to their launches. Orbit Following its launch, it raised itself into geostationary orbit by means of its onboard R-4D apogee motor, and was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
STS-70
STS-70 was the 21st flight of the Space Shuttle ''Discovery'', and the last of 7 shuttle missions to carry a Tracking and Data Relay Satellite (TDRS). This was the first shuttle mission controlled from the new mission control center room at the Johnson Space Center in Houston. STS-70 was also the first flight of the new Block 1 orbiter main engine, designed to improve both engine performance and safety. The mission was launched from Kennedy Space Center in Florida on 13 July 1995, only six days after the landing of sister ship ''Atlantis'', marking the fastest turnaround between flights in the history of the program. Crew Preparations and Launch STS-70 had originally moved ahead of STS-71 because of a delay in the launch of the Russian Spektr laboratory module to the Russian space station Mir. However, on 31 May 1995 shuttle managers assessed damage to the External Tank of STS-70 caused by nesting flicker woodpeckers. The damage consisted of about 71 holes (ranging in size f ...

TDRS-7
TDRS-7, known before launch as TDRS-G, is an American communications satellite, of first generation, which is operated by NASA as part of the Tracking and Data Relay Satellite System. It was constructed by TRW as a replacement for TDRS-B, which had been lost in the ''Challenger'' accident, and was the last first generation TDRS satellite to be launched. History TDRS-7 is based on a custom satellite bus which was used for all seven first generation TDRS satellites. Whilst similar to its predecessors, it differed from them slightly in that twelve G/H band (C band (IEEE)) transponders which had been included on the previous satellites were omitted. It was the last communications satellite, other than amateur radio spacecraft, to be deployed by a Space Shuttle. Launch The TDRS-G satellite was deployed from during the STS-70 mission in 1995. ''Discovery'' was launched from Kennedy Space Center Launch Complex 39B at 13:41:55 UTC on 13 July 1995. TDRS-G was deployed from ''Disco ...

STS-54
STS-54 was a NASA ''Space Transportation System'' (Space Shuttle) mission using Space Shuttle ''Endeavour''. This was the third flight for ''Endeavour'', and was launched on January 13, 1993 with Endeavour returning to the Kennedy Space Center on January 19, 1993. Crew Mission highlights The primary payload was the fifth TDRS satellite, TDRS-F, which was deployed on day one of the mission. It was later successfully transferred to its proper orbit by the Inertial Upper Stage (IUS). Also carried into orbit in the payload bay was a Hitchhiker experiment called the Diffuse X-ray Spectrometer (DXS). This instrument collected data on X-ray radiation from diffuse sources in deep space. Other middeck payloads to test the effects of microgravity included the Commercial General Bioprocessing Apparatus (CGPA) for-life sciences research; the Chromosome and Plant Cell Division in Space Experiment (CHROMEX) to-study plant growth; the Physiological and Anatomical Rodent Experiment ( ...

TDRS-6
TDRS-6, known before launch as TDRS-F, is an American communications satellite, of first generation, which is operated by NASA as part of the Tracking and Data Relay Satellite System. It was constructed by TRW, and is based on a custom satellite bus which was used for all seven first generation TDRS satellites. History TDRS-F was deployed from during the STS-54 mission in 1993. ''Endeavour'' was launched from Launch Complex 39B at the Kennedy Space Center, at 13:59:30 UTC on 13 January 1993. TDRS-F was deployed from ''Endeavour'' around six hours after launch, and was raised to geosynchronous orbit by means of an Inertial Upper Stage. Deployment The two-stage solid-propellent Inertial Upper Stage made two burns. The first stage burn occurred shortly after deployment from ''Endeavour'', and placed the satellite into a geosynchronous transfer orbit (GTO). At 02:26 UTC on 14 January 1993, it reached apogee, and the second stage fired, placing TDRS-F into geosynchronous orbit. ...

STS-43
STS-43, the ninth mission for Space Shuttle ''Atlantis'', was a nine-day mission whose primary goal was launching the TDRS-E satellite (TDRS-5). The flight also tested an advanced heatpipe radiator for potential use on the then-future space station and conducted a variety of medical and materials science investigations. Crew Crew seating arrangements Preparations and launch The launch took place on August 2, 1991, 11:01:59 a.m. EDT. Launch was originally set for July 23, 1991, but was moved to July 24 to allow time to replace a faulty integrated electronics assembly that controls orbiter/external tank separation. The mission was postponed again about five hours before liftoff on July 24, 1991, due to a faulty main engine controller on the number three main engine. The controller was replaced and retested; launch was reset for August 1, 1991. Liftoff set for 11:01 a.m. delayed due to cabin pressure vent valve reading and postponed at 12:28 p.m. due to unacceptable re ...

STS-29
STS-29 was the 28th NASA Space Shuttle mission, during which Space Shuttle ''Discovery'' inserted a Tracking and Data Relay Satellite (TDRS) into Earth orbit. It was the third shuttle mission following the ''Challenger'' disaster in 1986, and launched from Kennedy Space Center, Florida, on March 13, 1989. STS-29R was the eighth flight of ''Discovery'' and the 28th Space Shuttle mission overall; its planned predecessor, STS-28, was delayed until August 1989. The mission was technically designated STS-29R as the original STS-29 designator belonged to STS-61-A, the 22nd Space Shuttle mission. Official documentation and paperwork for that mission contained the designator STS-29 when it was allocated to Space Shuttle ''Columbia'' and later as STS-30 when allocated to ''Challenger''. As STS-51-L was designated STS-33, future flights with the STS-26 through STS-33 designators would require the R in their documentation to avoid conflicts in tracking data from one mission to another ...

STS-26
STS-26 was the 26th NASA Space Shuttle mission and the seventh flight of the orbiter ''Discovery''. The mission launched from Kennedy Space Center, Florida, on September 29, 1988, and landed four days later on October 3, 1988. STS-26 was declared the "Return to Flight" mission, being the first mission after the Space Shuttle ''Challenger'' disaster of January 28, 1986. It was the first mission since STS-9 to use the original Space Transportation System (STS) numbering system, the first to have all its crew members wear pressure suits for launch and landing since STS-4, and the first mission with bailout capacity since STS-4. STS-26 was also the first U.S. space mission with an all-veteran crew since Apollo 11, with all of its crew members having flown at least one prior mission. The mission is technically designated STS-26R, as the original STS-26 designation previously belonged to STS-51-F (also known as Spacelab-2).
