List Of Large Reentering Space Debris
This is a list of artificial objects reentering Earth's atmosphere by mass (see space debris). Such objects are often completely destroyed by reentry heating, but large enough objects or components can survive. Most of the objects which reenter are relatively small; larger objects have survived but usually break up into smaller pieces during reentry. The list includes group entries for the 134 Space Shuttle external tanks used between 1981 and 2011. During Space Shuttle launches, the tanks reached space without reaching orbit and re-entered the atmosphere, breaking apart before impacting the ocean. The mass of those tanks varied throughout the years, as improvements made them lighter - successive modifications reduced their empty weight from approximately to approximately for the Super Lightweight Tank used after 1998. The tanks were also not necessarily completely empty when discarded. Many other launch systems have discarded spent stages into space, but not all stages go ...

STS-135 External Tank Floats Away
STS-135 ( ISS assembly flight ULF7) was the 135th and final mission of the American Space Shuttle program. It used the orbiter '' Atlantis'' and hardware originally processed for the STS-335 contingency mission, which was not flown. STS-135 launched on 8 July 2011, and landed on 21 July 2011, following a one-day mission extension. The four-person crew was the smallest of any shuttle mission since STS-6 in April 1983. The mission's primary cargo was the Multi-Purpose Logistics Module (MPLM) ''Raffaello'' and a Lightweight Multi-Purpose Carrier (LMC), which were delivered to the International Space Station (ISS). The flight of ''Raffaello'' marked the only time that ''Atlantis'' carried an MPLM. Although the mission was authorized, it initially had no appropriation in the NASA budget, raising questions about whether the mission would fly. On 20 January 2011, program managers changed STS-335 to STS-135 on the flight manifest. This allowed for training and other mission specific ...

Phobos-Grunt
Fobos-Grunt or Phobos-Grunt (russian: link=no, Фобос-Грунт, where ''грунт'' refers to the ''ground'' in the narrow geological meaning of any type of soil or rock exposed on the surface) was an attempted Russian sample return mission to Phobos, one of the moons of Mars. Fobos-Grunt also carried the Chinese Mars orbiter Yinghuo-1 and the tiny Living Interplanetary Flight Experiment funded by the Planetary Society. It was launched on 8 November 2011, at 20:16 UTC, from the Baikonur Cosmodrome, but subsequent rocket burns intended to set the craft on a course for Mars failed, leaving it stranded in low Earth orbit. Efforts to reactivate the craft were unsuccessful, and it fell back to Earth in an uncontrolled re-entry on 15 January 2012, over the Pacific Ocean, west of Chile. The return vehicle was to have returned to Earth in August 2014, carrying up to of soil from Phobos. Funded by the Russian Federal Space Agency and developed by Lavochkin and the Russian Spa ...

Compton Gamma Ray Observatory
The Compton Gamma Ray Observatory (CGRO) was a space observatory detecting photons with energies from 20 k eV to 30 GeV, in Earth orbit from 1991 to 2000. The observatory featured four main telescopes in one spacecraft, covering X-rays and gamma rays, including various specialized sub-instruments and detectors. Following 14 years of effort, the observatory was launched from Space Shuttle ''Atlantis'' during STS-37 on April 5, 1991, and operated until its deorbit on June 4, 2000. It was deployed in low Earth orbit at to avoid the Van Allen radiation belt. It was the heaviest astrophysical payload ever flown at that time at . Costing $617 million, the CGRO was part of NASA's " Great Observatories" series, along with the Hubble Space Telescope, the Chandra X-ray Observatory, and the Spitzer Space Telescope. It was the second of the series to be launched into space, following the Hubble Space Telescope. The CGRO was named after Arthur Compton, an American physicis ...

Cosmos 1443
The TKS spacecraft (russian: Транспортный корабль снабжения, , ''Transport Supply Spacecraft'', GRAU index 11F72) was a Soviet spacecraft conceived in the late 1960s for resupply flights to the military Almaz space station. The spacecraft was designed for both crewed and autonomous uncrewed cargo resupply flights, but was never used operationally in its intended role – only four test missions were flown (including three that docked to Salyut space stations) during the program. The Functional Cargo Block (FGB) of the TKS spacecraft later formed the basis of several space station modules, including the Zarya FGB module on the International Space Station. The TKS spacecraft consisted of two spacecraft mated together, both of which could operate independently: * The VA spacecraft (known mistakenly in the West as the ''Merkur spacecraft''), which would have housed the cosmonauts during launch and reentry of a TKS spacecraft, while traveling to and fr ...

Apollo SA-7 CSM BP-15
AS-102 (also designated SA-7) was the seventh flight of the Saturn I launch vehicle, which carried the boilerplate Apollo spacecraft BP-15 into low Earth orbit. The test took place on September 18, 1964, lasting for five orbits (about seven and a half hours). The spacecraft and its upper stage completed 59 orbits before reentering the atmosphere and crashing in the Indian Ocean on September 22, 1964. Objectives AS-102 was designed to repeat the flight of AS-101. It would once again carry a boilerplate Apollo command and service module. The only difference from Boilerplate 13 carried on AS-101 was that on Boilerplate 15, one of the simulated reaction control system thruster quads (attitude control thrusters) was instrumented to record launch temperatures and vibrations. Another major difference on AS-102 was that the launch escape system (LES) tower would be jettisoned using the launch escape and pitch control motors. AS-102 was the first time a Saturn rocket carried a progra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Apollo SA-6 CSM BP-13
AS-101 (also designated SA-6) was the sixth flight of the Saturn I launch vehicle, which carried the first boilerplate Apollo spacecraft into low Earth orbit. The test took place on May 28, 1964, lasting for four orbits (about six hours). The spacecraft and its upper stage completed a total of 54 orbits before reentering the atmosphere and crashing in the Pacific Ocean on June 1, 1964. The flight experienced a single anomaly: one of the eight first-stage Saturn I engines shut down early, but the guidance system compensated by burning the remaining seven engines longer. AS-101 was followed by four more flights to verify the launch aerodynamics of the Apollo command and service module (CSM) and its launch escape system (LES) tower. Boilerplate Apollo The first five launches of the Saturn I had carried Jupiter nosecones, a proven design which allowed engineers to focus on development of the rocket. To verify the launch aerodynamics of the CSM, AS-101 carried BP-13, a boilerpl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Apollo SA-5 Nose Cone
Saturn-Apollo 5 (SA-5) was the first launch of the Block II Saturn I rocket and was part of the Apollo program. In 1963, President Kennedy identified this launch as the one which would place US lift capability ahead of the Soviets, after being behind for more than six years since Sputnik. Upgrades and objectives The major changes that occurred on SA-5 were that for the first time the Saturn I would fly with two stages - the S-I first stage and the S-IV second stage. The second stage featured six engines burning liquid hydrogen. Although this engine design (RL10) was meant to be tested several years earlier in the Centaur upper stage, in the end the first Centaur was launched only two months before SA-5. This rocket stage was delivered to the Cape by a modified B-377 aircraft, the '' Aero Spacelines Pregnant Guppy''. Other major design changes included the enlargement of the fuel tanks on the first stage. For the first time the rocket would carry its planned 750,000 lb (340,0 ...

Salyut 4
Salyut 4 (DOS 4) (russian: Салют-4; English translation: Salute 4) was a Salyut space station launched on December 26, 1974 into an orbit with an apogee of 355 km, a perigee of 343 km and an orbital inclination of 51.6 degrees. It was essentially a copy of the DOS 3 (or Kosmos 557), and unlike its ill-fated sibling it was a complete success. Three crews attempted to make stays aboard Salyut 4 ( Soyuz 17 and Soyuz 18 docked; Soyuz 18a suffered a launch abort). The second stay was for 63 days duration, and an unmanned capsule, called Soyuz 20, remained docked to the station for three months, proving the system's long-term durability despite some deterioration of the environmental system during Soyuz 18's mission. Salyut 4 was deorbited February 2, 1977, and re-entered the Earth's atmosphere on February 3. Description Salyut 4 represented the second phase of DOS civilian space station. Although the basic design of Salyut 1 was retained, it switched to three large sol ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Salyut 3
Salyut 3 (russian: Салют-3; en, Salute 3; also known as OPS-2 or Almaz 2Portree (1995).) was a Soviet space station launched on 25 June 1974. It was the second Almaz military space station, and the first such station to be launched successfully. It was included in the Salyut program to disguise its true military nature.Hall and Shayer (2003). Due to the military nature of the station, the Soviet Union was reluctant to release information about its design, and about the missions relating to the station.Zimmerman (2003). It attained an altitude of 219 to 270 km on launchBond (2002). and NASA reported its final orbital altitude was 268 to 272 km. Only one of the three intended crews successfully boarded and manned the station, brought by Soyuz 14; Soyuz 15 attempted to bring a second crew but failed to dock. Although little official information has been released about the station, several sources report that it contained multiple Earth-observation cameras, as well a ...

Salyut 1
Salyut 1 (DOS-1) (russian: Салют-1) was the world's first space station launched into low Earth orbit by the Soviet Union on April 19, 1971. The Salyut program followed this with five more successful launches of seven more stations. The final module of the program, ''Zvezda'' (DOS-8), became the core of the Russian segment of the International Space Station and remains in orbit. Salyut 1 was modified from one of the Almaz airframes, and was made out of five components: a transfer compartment, a main compartment, two auxiliary compartments, and the Orion 1 Space Observatory. Salyut 1 was visited by Soyuz 10 and Soyuz 11. The hard-docking of Soyuz 10 failed and the crew had to abort this mission. The Soyuz 11 crew achieved successful hard docking and performed experiments in Salyut 1 for 23 days. However, they were killed by asphyxia caused by failure of a valve just prior to Earth reentry, and are the only people to have died above the Kármán line. Salyut 1's mission w ...
