Space Shuttle Discovery was the third operational space shuttle. It was the third orbiter built and the lightest one because of its lightweight thermal blanket material. Discovery was commonly referred to as OV-103, for Orbiter Vehicle-103. Discovery was first flown in 1984 and retired in 2011.

Space Shuttle Discovery Picture

Specs: Empty Weight: 151,419 lbs at rollout and 171,000 lbs with main engines installed.

Name

Space Shuttle iscovery was named after one of two ships that were used by the British explorer James Cook in the 1770s during voyages in the South Pacific that led to the discovery of the Hawaiian Islands. Another of his ships was the Endeavour, the namesake of NASA's orbiter. Cook also used Discovery to explore the coasts of southern Alaska and north-western Canada. During the American Revolutionary War, Benjamin Franklin made a safe conduct request for the British vessel because of the scientific importance of its research.


Upgrades and Features

Discovery benefited from lessons learned in the construction and testing of Enterprise, Columbia and Challenger. At rollout, its weight was some 6,870 pounds less than Columbia. Two orbiters, Challenger and Discovery, were modified at Kennedy Space Center (KSC) to enable them to carry the Centaur upper stage in the payload bay. These modifications included extra plumbing to load and vent Centaur's cryogenic (L02/LH2) propellants (other IUS/PAM upper stages use solid propellants), and controls on the aft flight deck for loading and monitoring the Centaur stage. No Centaur flight was ever flown and after the loss of Challenger it was decided that the risk was too great to launch a shuttle with a fuelled Centaur upper stage in the payload bay.

19. STS-64 (9 September 1994) - Carried the LIDAR In-Space Technology Experiment (LITE), a project to measure atmospheric parameters from a space platform.

20. STS-63 (3 February 1995) - The second mission of the US / Russian Shuttle-Mir Program, which carried out the first rendezvous of the American Space Shuttle with Mir Space Stationr. STS-63 was the first mission to see the use of the new full-pressure Advanced Crew Escape System Pressure Suit, which eventually replaced the partial-pressure Launch-Escape Suit.

21. STS-70 (13 July 1995) - Launch and deployment of the 7th Tracking and Data Relay Satellite (TDRS) by means of the two-stage Inertial Upper Stage (IUS) solid rocket. STS-70 marked the maiden flight of the new Block 1 orbiter main engine.

Discovery underwent a nine-month Orbiter Maintenance Down Period (OMDP) in Palmdale California. The vehicle was outfitted with a 5th set of cryogenic tanks and an external airlock to support missions to the International Space Station. Discovery departed Palmdale, California, riding piggy-back on a modified Boeing 747 at 10:01am EDT 28 June 1996 and arrived at Kennedy Space Center on 29 June 1996.


23. STS-85 (7 August 1997) - Carried a complement of payloads in the cargo bay: the Cryogenic Infrared Spectrometers and Telescopes for the Atmosphere-Shuttle Pallet Satellite-2 (CRISTA-SPAS-02); the Japanese Manipulator Flight Development (MFD); the Technology Applications and Science-01 (TAS-1) and the International Extreme Ultraviolet Hitchhiker-02 (IEH-02).

30. STS-105 (10 August 2001) - International Space Station crew and supplies delivery for Expedition 2 and Expedition 3.


In 2002, Discovery underwent an over two year Orbiter Maintenance Down Period that provided 99 upgrades and 88 special tests, including a number of changes to make it safer for flight. Each wing contains new sensors that are able to take 20,000 samples per second and detect micrometeorite or other impacts. There are 22 temperature sensors and 66 accelerometers. Discovery also has a new 50-foot inspection boom that can be used to check Discovery's underside for damage.


31. STS-114 (26 July 2005) - First return to flight since Space Shuttle Columbia Disaster, tested safety improvements and resupplied the ISS. Eileen Collins was the first woman to pilot and command a Space Shuttle. She was the first astronaut to fly the space shuttle through a complete 360-degree pitch maneuver. This was necessary so astronauts aboard the ISS could take photographs of the shuttle's belly, to ensure there was no threat from debris-related damage to the shuttle.

32. STS-121 (4 July 2006) - The second return to flight mission since the 2003 Space Shuttle Columbia Disaster. Tested new safety and repair techniques, delivered supplies, equipment and European Space Agency (ESA) astronaut Thomas Reiter from Germany to the ISS.

38. STS-131 (5 April 2010) Multi-Purpose Logistics Module loaded with supplies and equipment for the International Space Station

39. STS-133 (3 February 2011) Planned International Space Station flight. Final mission for Discovery and last flight of the Space Shuttle program.


Did you know?

Other famous ships have carried the name Discovery, including one used by Henry Hudson to explore Hudson Bay in Canada as well as search for what was hoped to be the northwest passage from the Atlantic to the Pacific in 1610 and 1611. Another, based on whaling ship design, was used by the British Royal Geographical Society for an expedition to the North Pole in 1875. This organization then built another Discovery in 1901 to conduct its Antarctic expedition that concluded in 1904. This ship still exists and is being preserved by the Society.
