Space Shuttle Atlantis

Space Shuttle Atlantis, Orbiter Vehicle Designation: OV-104 was the last active Space Shuttle orbiter in the Space Shuttle fleet belonging to the National Aeronautics and Space Administration (NASA), the spaceflight and space exploration agency of the United States. Atlantis was the fourth operational (and the next-to-the-last) Space Shuttle to be constructed by the Rockwell International company in Southern California, and it was delivered to the John F. Kennedy Space Center in eastern Florida in April 1985. Atlantis was the only orbiter which lacked the ability to draw power from the International Space Station while docked there; it had to continue to provide its own power through fuel cells.

The last mission of Atlantis was STS-135, the last flight before the Shuttle program ended. This final flight was authorized by President Barack Obama in October 2010, to bring additional supplies to the International Space Station and take advantage of the processing performed for the Launch on Need mission, which would only have been flown in the event that Endeavour's STS-134 crew required rescue. Atlantis launched successfully for the final time on 8 July 2011 at 16:29 UTC, landing at the John F. Kennedy Space Center on 21 July 2011 at 09:57 UTC. By the end of its final mission, Atlantis had orbited the Earth 4,848 times, traveling nearly 126 million miles in space or more than 525 times the distance from the Earth to the Moon.

Atlantis was named after RV Atlantis, a two-masted sailing ship that operated as the primary research vessel for the Woods Hole Oceanographic Institution from 1930 to 1966.[6] The 460-ton ketch carried a crew of 17 and had room for 5 scientists. The former RV Atlantis is now commissioned as an oceanographic research vessel in the Argentine Naval Prefecture under the name Dr. Bernardo Houssay and finishing a lengthy period of restoration.

Atlantis was completed in about half the time it took to build Space Shuttle Columbia.

When it rolled out of the Palmdale assembly plant, weighing 151,315 pounds Atlantis was nearly 3.5 tons lighter than Columbia. Atlantis is the lightest shuttle of the remaining fleet, weighing three pounds less than the Space Shuttle Endeavour (with the three main engines).

Notable missions

Space Shuttle Atlantis lifted off on its maiden voyage on 3 October 1985, on mission STS-51-J, the second dedicated Department of Defense flight. It flew one other mission, STS-61-B, the second night launch in the shuttle program, before the Space Shuttle Challenger disaster temporarily grounded the shuttle fleet in 1986. Atlantis was used for ten flights between 1988 and 1992. Two of these, both flown in 1989, deployed the planetary probes Magellan to Venus (on STS-30) and Galileo to Jupiter (on STS-34). With STS-30 Atlantis became the first shuttle to launch an interplanetary probe. During another mission, STS-37 flown in 1991, Atlantis deployed the Compton Gamma Ray Observatory. Beginning in 1995 with STS-71, Atlantis made seven straight flights to the former Russian space station Mir as part of the Shuttle-Mir Program. STS-71 marked a number of firsts in human spaceflight: 100th U.S. manned space flight; first U.S. shuttle-Russian Space Station Mir docking and joint on-orbit operations; and first on-orbit changeout of shuttle crew. When linked, Atlantis and Mir together formed the largest spacecraft in orbit at the time.

Shuttle Atlantis has also delivered several vital components for the construction of the International Space Station (ISS). During the February 2001 mission STS-98 to the ISS, Atlantis delivered the Destiny Module, the primary operating facility for U.S. research payloads aboard the ISS. The five hour 25 minute third spacewalk performed by astronauts Robert Curbeam and Thomas Jones during STS-98 marked NASA's 100th extra vehicular activity in space. The Quest Joint Airlock, was flown and installed to the ISS by Atlantis during the mission STS-104 in July 2001. The successful installation of the airlock gave on-board space station crews the ability to stage repair and maintenance spacewalks outside the ISS using U.S. EMU or Russian Orlan space suits. The first mission flown by Atlantis after the Space Shuttle Columbia disaster was STS-115, conducted during September 2006. The mission carried the P3/P4 truss segments and solar arrays to the ISS. On ISS assembly flight STS-122 in February 2008, Atlantis delivered the Columbus laboratory to the ISS. Columbus laboratory is the largest single contribution to the ISS made by the European Space Agency (ESA).

In May 2009 Atlantis flew a seven member crew to the Hubble Space Telescope for its Servicing Mission 4, STS-125. The mission was a success, with the crew completing five space walks totaling 37 hours to install new cameras, batteries, a gyroscope and other components to the telescope.

Among the five space shuttles flown into space, Atlantis has conducted a subsequent mission in the shortest time after the previous mission when it launched in November, 1985 on STS-61-B, only 50 days after its previous mission, STS-51-J.

The longest mission flown using shuttle Atlantis was STS-117 and lasted almost 14 days in June 2007. During STS-117, Atlantis' crew added a new starboard truss segment and solar array pair (the S3/S4 truss), folded the P6 array in preparation for its relocation and performed four spacewalks. Atlantis was not equipped to take advantage of the Station-to-Shuttle Power Transfer System so missions could not be extended by making use of power provided by ISS.

During the STS-129 post-flight interview on 16 November 2009 shuttle launch director Mike Leinbach said that Atlantis officially beat shuttle Discovery on the record low amount of Interim Problem Reports, with a total of just 54 listed since returning from the STS-125. He continued to add "It is due to the team and the hardware processing. They just did a great job. The record will probably never be broken again in the history of the Space Shuttle Program, so congratulations to them". However, during the STS-132 post-launch interview on 14 May 2010, shuttle launch director Mike Leinbach said that Atlantis beat its previous record low amount of Interim Problem Reports, with a total of 46 listed between STS-129 and STS-132.

Orbiter Maintenance Down Periods

To date Atlantis has gone through two overhauls of scheduled Orbiter Maintenance Down Periods (OMDPs) during its operational history.

Atlantis arrived at Palmdale, California in October 1992 for OMDP-1. During that visit 165 modifications were made over the next 20 months. These included the installation of a drag chute, new plumbing lines to configure the orbiter for extended duration, more than 800 new heat tiles and blankets and new insulation for main landing gear and structural modifications to the airframe.

On 5 November 1997, Atlantis again arrived at Palmdale for OMDP-2 which was completed on 24 September 1998. The 130 modifications carried out during OMDP-2 included glass cockpit displays, replacement of TACAN navigation with GPS and ISS airlock and docking installation. Several weight reduction modifications were also performed on the orbiter including replacement of Advanced Flexible Reusable Surface Insulation (AFRSI) insulation blankets on upper surfaces with FRSI. Moreover lightweight crew seats were installed and the Extended Duration Orbiter (EDO) package installed on OMDP-1 was removed to lighten Atlantis to better serve its prime mission of servicing the ISS.

During the stand down period post Columbia accident, Atlantis went through over 75 modifications to the orbiter ranging from very minor bolt change-outs to window change-outs and different fluid systems.

Planned decommissioning

NASA administrator Charlie Bolden announces that Atlantis will remain at KSC on permanent exhibition.

NASA had planned to withdraw Atlantis from service in 2008, as the orbiter would have been due to undergo its third scheduled OMDP. However, because of the final retirement of the shuttle fleet in 2010, this was deemed uneconomical. It was planned that Atlantis would be kept in near flight condition to be used as a parts hulk for Discovery and Endeavour. However, with the significant planned flight schedule up to 2010, the decision was taken to extend the time between OMDPs, allowing Atlantis to be retained for operations. Atlantis has been swapped for one flight of each Discovery and Endeavour in the current flight manifest. Atlantis had completed what was meant to be its last flight, STS-132, prior to the end of the shuttle program, but the extension of the Shuttle program into 2011 led to Atlantis being the STS-135, the final Space Shuttle mission in July 2011.

Once Atlantis is finally decommissioned, it will be displayed at the Kennedy Space Center Visitor Complex. NASA Administrator Charles Bolden announced the decision at an employee event held on 12 April 2011 to commemorate the 30th anniversary of the first shuttle flight: "First, here at the Kennedy Space Center where every shuttle mission and so many other historic human space flights have originated, we'll showcase my old friend, Atlantis.

The Visitor Complex plans to suspend Atlantis with cargo bay doors opened such that it appears to be back in orbit around the Earth. A multi-story digital projection of the home planet that will rotate behind the orbiter in a 64,000 square-foot indoor facility is also proposed.Ground breaking of the facility is planned to begin in 2012 with the exhibit opening in 2013.

Crews

A total of 155 unique individuals have flown with Space Shuttle Atlantis over the course of its 32 missions. Because the shuttle sometimes flew crew members arriving and departing Mir and the ISS, not all of them launched and landed on Atlantis.

Astronaut Clayton Anderson, ESA astronaut Leopold Eyharts and Russian cosmonauts Nikolai Budarin and Anatoly Solovyev only launched on Atlantis. Similarly, astronauts Daniel Tani and Sunita Williams, as well as cosmonauts Vladimir Dezhurov and Gennady Strekalov only landed with Atlantis. Only 146 men and women both launched and landed aboard Atlantis.

Some of those people however, flew with Atlantis more than once. Taking them into account, 203 total seats were filled over Atlantis' 32 missions. Astronaut Jerry Ross holds the record for the most flights aboard Atlantis at five.

Astronaut Rodolfo Neri Vela who flew aboard Atlantis on STS-61-B mission in 1985 became the first and so far only Mexican to have traveled to space. ESA astronaut Dirk Frimout who flew on STS-45 as a payload specialist was the first Belgian in space. STS-46 mission specialist Claude Nicollier was the first astronaut from Switzerland. On the same flight, astronaut Franco Malerba became the first citizen of Italy to travel to space.

Astronaut Michael Massimino who flew on STS-125 mission became the first person to use Twitter in space in May 2009.

Having flown aboard Atlantis as part of the STS-132 crew in May 2010 and Discovery as part of the STS-133 crew in February/March 2011, Stephen Bowen became the first NASA astronaut to be launched on consecutive missions.
