AKA: OV-103. Status: Operational 1984. First Launch: 1984-08-30. Last Launch: 2011-02-24. Number: 39 . Payload: 24,990 kg (55,090 lb). Thrust: 53.37 kN (11,997 lbf). Gross mass: 116,884 kg (257,685 lb). Unfuelled mass: 104,472 kg (230,321 lb). Specific impulse: 316 s. Height: 37.24 m (122.17 ft). Span: 23.79 m (78.05 ft).
Discovery, the third orbiter to become operational at Kennedy Space Center, was named after one of two ships 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. Empty Weight was 68,670 kg at rollout and 77,550 kg with main engines installed.
Discovery benefited from lessons learned in the construction and testing of Enterprise, Columbia and Challenger. At rollout, its weight was some 3115 kg less than Columbia. Two orbiters, Challenger and Discovery, were modified at 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 Lox/LH2 propellants (other IUS/PAM upper stages used solid propellants), and controls on the aft flight deck for loading and monitoring the Centaur stage. No Centaur flight was ever flown. After the loss of Challenger it was decided that the risk was too great to launch a shuttle with a fueled Centaur upper stage in the payload bay.

After a spectacular night launch, the Shuttle completed its rendezvous with Hubble Space Telescope on February 13. Over the next four days five spacewalks were undertaken to renovate Hubble.
The Hubble Space Telescope was released back into orbit at 06:41 GMT on February 19. Discovery landed on Runway 15 at Kennedy Space Center at 08:32 GMT on February 21.
Deployed and retrieved the CRISTA-SPAS-2 (the Cryogenic Infrared Spectrometers and Telescopes for the Atmosphere-Shuttle Pallet Satellite-2) designed to study Earth's middle atmosphere. The CRISTA-SPAS-2 was making its second flight on the Space Shuttle and represented the fourth mission in a cooperative venture between the German Space Agency (DARA) and NASA.
CRISTA-SPAS was deployed by the RMS arm at 22:27 GMT on August 7 and was recaptured by Discovery's RMS arm at 15:14 GMT on August 16. Because of unfavorable weather conditions at the primary shuttle landing site at the Kennedy Space Center, Discovery was waved off for its scheduled August 18 landing. STS-85 landed the next day, at Kennedy Space Center at 11:08 GMT.
The final shuttle-Mir mission, STS-91 recovered NASA astronaut Andy Thomas from the Mir station and took Russian space chief and ex-cosmonaut Valeri Ryumin to Mir for an inspection tour of the ageing station. This was the first test of the super lightweight Aluminium-Lithium alloy external tank, designed to increase shuttle payload to the Mir / International Space Station orbit by 4,000 kg. At 22:15 GMT Discovery entered an initial 74 x 324 km x 51.6 deg orbit, with the OMS-2 burn three quarters of an hour later circulising the chase orbit. Discovery docked with the SO module on Mir at 17:00 GMT on June 4. NASA equipment was retrieved from the station, and Discovery undocked at 16:01 GMT on June 8, and landed on Runway 15 at Kennedy Space Center at 18:00 GMT on June 12.
The flight of STS-95 provoked more publicity for NASA than any other flight in years, due to the presence of ex-astronaut Senator John Glenn on the crew, which also included the first Spanish astronaut, Pedro Duque. The US Navy PANSAT student satellite was deployed on Oct 30 into a 550 km x 561 x 28.5 degree orbit. The Spartan 201 satellite was deployed from Discovery on November 1 and retrieved on November 3. Spartan 201 was on its fifth mission to observe the solar corona. The data on this mission would be used to recalibrate the SOHO satellite which recently resumed observation of the Sun following loss of control. Discovery landed at 17:03:31 GMT November 7 on Runway 33 at the Shuttle Landing Facility at Kennedy Space Center.
Discovery docked at the PMA-2 end of the International Space Station PMA-2/Unity/PMA-1/Zarya stack. The crew transferred equipment from the Spacehab Logistics Double Module in the payload bay to the interior of the station. Tammy Jernigan and Dan Barry made a space walk to transfer equipment from the payload bay to the exterior of the station. The ODS/EAL docking/airlock truss carried two TSA (Tool Stowage Assembly) packets with space walk tools. The Integrated Cargo Carrier (ICC), built by Energia and DASA-Bremen, carried parts of the Strela crane and the US OTD crane as well as the SHOSS box which contains three bags of tools and equipment to be stored on ISS's exterior.
The STS-96 payload bay manifest:
On May 30 at 02:56 GMT Tammy Jernigan and Dan Barry entered the payload bay of Discovery from the tunnel adapter hatch, and made a 7 hr 55 min space walk, transferring equipment to the exterior of the station.
On May 31 at 01:15 GMT the hatch to Unity was opened and the crew began several days of cargo transfers to the station. Battery units and communications equipment were replaced and sound insulation was added to Zarya. Discovery undocked from ISS at 22:39 GMT on June 3 into a 385 x 399 km x 51.6 degree orbit, leaving the station without a crew aboard. On June 5 the Starshine satellite was ejected from the payload bay. The payload bay doors were closed at around 02:15 GMT on June 6 and the deorbit burn was at 04:54 GMT. Discovery landed on runway 15 at Kennedy Space Center at 06:02 GMT.
Hubble Space Telescope (HST) servicing mission SM-3A, delayed repeatedly by technical problems with the shuttle fleet after the near-disastrous previous launch. Finally launched after the last possible day to avoid Y2K computer problems; one spacewalk was cancelled so that the shuttle could return by December 28. Hubble was in a 591 km x 610 km x 28.5 deg orbit at launch. After separation of the external tank ET-101 the Orbiter was in a 56 km x 587 km x 28.5 deg transfer orbit. The OMS 2 burn at 0134 UTC raised the orbit to 313 km x 582 km. The payload bay contained:
ISS Logistics flight. 100th shuttle flight. Launch delayed from October 6. STS-92 brought the Z-1 Truss (mounted on a Spacelab pallet), Control Moment Gyros, Pressurised Mating Adapter-3 (PMA-3) and two DDCU (Heat pipes) to the International Space Station.
The RSRM-76 solid rocket boosters separated at 23:19 GMT and main engine cut-off (MECO) came at 23:25 GMT. External tank ET-104 separated into a 74 x 323 km x 51.6 deg orbit. At apogee at 00:01 GMT on Oct 12, Discovery's OMS engines fired to raise perigee to a 158 x 322 km x 51.6 deg orbit; ET-104 re-entered over the Pacific around 00:30 GMT. At Oct 12 on 03:01 GMT the NC1 burn raised the orbit to 180 x 349 km; NC3 on Oct 12 to 311 x 375 km; and the TI burn at 14:09 GMT on Oct 13 to 375 x 381 km x 51.6 deg. Discovery's rendezvous with the International Space Station came at 15:39 GMT on Oct 13, with docking at 17:45 GMT. The spaceship docked with PMA-2, the docking port on the +Y port of the Space Station's Unity module. Hatch was open to PMA-2 at 20:30 GMT the same day.
STS-92 Cargo Manifest
Total payload bay cargo: ca. 14,800 kg
The Z1 first segment of the space station truss was built by Boeing/Canoga Park and was 3.5 x 4.5 meters in size. It was attached to the +Z port on Unity. Z1 carried the control moment gyros, the S-band antenna, and the Ku-band antenna.
PMA-3, built by Boeing/Huntington Beach, was docked to the -Z port opposite Z1. PMA-3 was installed on a Spacelab pallet for launch.
On October 14 at 16:15 GMT the Z1 segment was unberthed from the payload bay and at around 18:20 GMT it was docked to the zenith port on the Unity module.
On October 15 at 14:20 GMT the ODS airlock was depressurised, beginning a spacewalk by Bill McArthur and Leroy Chiao. Official NASA EVA duration (battery power to repress) was 6 hours 28 minutes.
The second spacewalk was on October 16, with Jeff Wisoff and Mike Lopez-Alegria. The suits went to battery power at 14:15 GMT and Wisoff left the airlock at 14:21 GMT. Repressurisation began at 21:22 GMT for a duration of 7 hours 07minutes.
Leroy Chiao and Bill McArthur began the third STS-92 EVA at 15:30 GMT on October 17, completing their work at 22:18 GMT for a total time of 6 hours 48 minutes.
After the spacewalk, Discovery completed the second of the three station reboosts scheduled for STS-92. They fired reaction control system jets in a series of pulses of 1.4 seconds each, over a 30-minute period, gently raising the station's orbit by about 3.1 km.
The last of four successful spacewalks began on 18 October at 16:00 GMT and ended at 22:56 GMT, lasting 6 hours and 56 minutes. Jeff Wisoff and Mike Lopez-Alegria each jetted slowly through space above Discovery's cargo bay.
After the space walk, Discovery completed the third and final reboost of the space station.
On 19 October the astronauts worked within the ISS. They completed connections for the newly installed Z1 external framework structure and transferred equipment and supplies for the Expedition One first resident crew of the Station. The crew also tested the four 290-kg gyroscopes in the truss, called Control Moment Gyros, which will be used to orient the ISS as it orbits the Earth. They will ultimately assume attitude control of the ISS following the arrival of the U.S. Laboratory Destiny. The tests and the transfer of supplies into the Russian Zarya Module took longer than expected. As a result, the crew's final departure from the Station's Unity module was delayed. Melroy and Wisoff took samples from surfaces in Zarya to study the module's environment. They then unclogged the solid waste disposal system in the Shuttle's toilet, which was restored to full operation after a brief interruption in service.
Discovery undocked from the ISS at 16:08 GMT on 20 October. The final separation burn was executed about 45 minutes after undocking. The crew had added 9 tonnes to the station's mass, bringing it to about 72 tonnes. The return to earth, planned for 22 October, was delayed repeatedly due to high winds at the Kennedy landing site. The landing was finally made at Edwards Air Force Base, California, on October 24, at 22:00 GMT.
STS 102 was an American shuttle spacecraft that carried a crew of seven astronauts (six American and one Russian). The primary mission was to deliver a multi-rack Italian container (Leonardo MultiPurpose Logistics Module, LMPLM) to the Destiny Module of the International Space Station, ISS. It docked with the ISS at 05:34 UT on 9 March. The 6.4 m x 4.6 m cylindrical LMPLM delivered new equipment to Destiny, and retrieved used/unwanted equipment, and trash back to the shuttle. The crew did a few spacewalks to install a platform on the ISS to support a Canadian robot arm when it arrives next month. The STS 102 left behind three of the astronauts (two American and one Russian) and brought back the three astronauts (one American and two Russian) who had been inhabiting the ISS for about four and a half months. It landed at Cape Canaveral at 07:31 UT on 21 March.
Discovery was launched on mission STS-102 (Space Station flight 5A.1) into an initial 60 x 222 km x 51.6 deg orbit. The mission was delivery of supplies and equipment, and changeout of the Expedition One and Expedition Two station crews. STS-102 carried the Leonardo Multi Purpose Logistics Module (MPLM), built by Alenia Spazio (Torino), to the International Space Station. The 6.4 m x 4.6 m cylindrical MPLM was a descendant of the Spacelab long modules. Also carried was a Spacehab/Energia unpressurized Integrated Cargo Carrier with LCA/MTSAS-A, RU, and PFCS. A sidewall adapter beam with two GAS canisters (G-783 and WSVFM) was also on board. WSVFM measured vibration during launch. Another adapter beam, probably at the rear of the payload bay, carried SEM-9. SEM-9 and G-783 contained high school microgravity experiments.
Leonardo carried 16 'racks' of equipment, including the Human Research Facility Rack (Rack 13) which allowed the astronauts to do extensive medical experiments, the CHeCS Rack (28), the DDCU-1 and DDCU-2 racks (7 and 9), the Avionics-3 (Rack 6), and the MSS Avionics/Lab (Rack 11) and Avionics/Cupola (Rack 12) racks for a total of 7 equipment racks to be installed on Destiny. Three Resupply Stowage Racks (50, 51, 52) and four Resupply Stowage Platforms (180, 181, 182 and 188) remained installed on Leonardo, with their equipment bags being individually transferred to the Station. System Racks 2, 3, 4, 5 and 8 were already on Destiny together with stowage racks 110 through 117. Each rack had a mass of 150-300 kg.
The orbiter fired its OMS engines at 1221 GMT to raise the orbit to 185 x 219 km. Discovery docked with the PMA-2 port on the Station at 0639 GMT on March 10. The LCA (Lab Cradle Assembly) was attached to Destiny's +Z side during an EVA. It was to be used on the next mission to temporarily place a Spacelab pallet on Destiny during installation of the Station's robot arm. Later, it would be the site for the main Station truss, beginning with segment S0.
The PMA-3, on Unity at the -Z nadir position, had to be moved to the port position to make room for Leonardo. An external stowage platform was attached to Destiny and the External Stowage Platform and the PFCS Pump Flow Control System were added to the port aft trunnion on Destiny. A rigid umbilical (RU) was connected to the PDGF grapple fixture on Destiny to support the Station's future robot arm. Leonardo was docked to Unity at -Z for a while so that its cargo could be transferred to the station easily; it was then be returned to the payload bay and brought back to earth.
At 0232 GMT on March 19 command of ISS was transferred to Expedition 2 and the hatches were closed. Discovery undocked at 0432 GMT and flew once around the station before departing at 0548 GMT. ISS mass after undocking was 115527 kg. The OMS engines fired for the deorbit burn at 0625 GMT on March 21, and Discovery touched down on runway 15 at Kennedy Space Center at 0731 GMT.
STS 105 was an American shuttle that carried a crew of ten (including three crew for the ISS - one American and two Russian), five tonnes of supplies, hardware, and a bedroom suite to accommodate a third astronaut in the Destiny module. The crew installed in the station two new science experiment racks that were carried in the Leonardo container which was first lifted out of the shuttle and bolted to the Unity module. Leonardo then carried back all the trash from the ISS back to the shuttle. They crew installed the MISSE (Materials International Space Station Experiment) container outside the ISS to test the effect of radiation on materials and some low-cost science experiments such as microgravity cell growth studies inside the station.
The 15,107 kg payload consisted of:
The Leonardo MPLM module was lifted out of Discovery's payload bay at 1326 GMT on August 13 and docked to Unity's nadir at 1554 GMT. 3300 kg of cargo from Leonardo was transferred to the Station. Then 1700 kg of station garbage and materials were loaded into Leonardo. It was unberthed from Unity at 1816 GMT on August 19 and returned to the payload bay for the return to Earth at 1917 GMT.
Discovery undocked at 1452 GMT on August 20 with the Expedition 2 crew aboard, leaving Expedition 3 at the Station.
At 1830 GMT on August 20 the Simplesat test satellite was ejected from a GAS canister in the cargo bay. Discovery landed at Kennedy Space Center at 1822:58 GMT on August 22 on runway 15, after a deorbit burn at 1715 GMT. The Expedition Two crew of Usachyov, Voss and Helms had been in space for 167 days. Discovery was taken out of service after the flight for structural inspections. Its last maintenance down period was in 1995-1996.
The EVA ran from 0841 to 1606 UTC. The astronauts installed the NICMOS cooling system (NCS). During preparations for EVA-3, a problem with a valve on Grunsfeld's suit caused it to leak water, and Grunsfeld switched to Newman's suit. For each of EVA-3,4,5 the appropriate size legs and arms were replaced on the same basic HUT (Hard Upper Torso)/PLSS (Primary Life Support System) combination.
Return to flight after loss of Columbia. Delayed extensively as NASA attempted to fix the external tank foam-shedding problem that resulted in the loss of Columbia (first planned for September 12, 2004, the launch slipped to March; May 14, 15 and 22; July 13, 2005). Discovery safely reached orbit at a total mass of 121,485 kg, but extensive video coverage detected external tank foam shedding during ascent. Discovery docked at the Pirs module of the ISS on 28 July 28 at 11:18 GMT. Following replenishment of the station (using the Raffaello MPLM-6 module with 8240 kg of supplies), a series of spacewalks verified the integrity of the shuttle's heat shield and tested repair techniques, Discovery undocked from the ISS at 07:24 GMT on 6 August and landed safely on Runway 22 at Edwards Air Force Base at 12:11 GMT on 9 August. However the shuttle fleet was immediately grounded again while NASA attempted to find a permanent fix to the external tank foam woes.
Flight delayed after the Columbia disaster. No crew had been named at the time of the loss of Columbia. STS-132 was to have flown ISS resupply mission ISS-UF6. Supplies and equipment would have been delivered via an MPLM and EXPRESS Pallet in the cargo bay.
The shuttle was launched using external tank ET-119 and solid motors RSRM-93. Cameras revealed that large chunks of foam were still shed from the external tank during the ascent to orbit. However examination of the heat shield using a new extension and sensors attached to the shuttle's robot arm revealed no significant damage. Discovery docked with the PMA-2 adapter on the Destiny module of the ISS at 14:52 GMT on 6 July. On July 7 the Leonardo cargo module was moved from the shuttle payload bay by the robot arm and docked to the Unity Module of the ISS between 09:42 and 11:50 GMT. The crew then began unloading the spare parts and supplies in the module to the station. A series of three EVAs conducted on 8 to 12 July tested the new equipment and techniques for repairing the shuttle heat shield in case of damage, and did some preliminary installations on the exterior of the ISS to pave the way for continued station assembly missions. On 14 July, the station's SSRMS robot moved the Leonardo module from the station back to the shuttle cargo bay between 13:08 and 14:50 GMT. The shuttle separated from the ISS, and fired its engines at 12:07 GMT on 17 July to make a 92 m/s deorbit maneuver. Discovery landed at the Kennedy Space Center at 13:14 GMT. European astronaut Reiter was left behind to make up part of the EO-13 resident crew on the station.
The mission used solid rocket booster pair RSRM-95 and external tank ET-123. At SSME burnout Discovery was in a 58 km x 220 km x 51.6 deg preliminary burn. The OMS-2 burn at 02:25 GMT placed the shuttle in a stable 225 x 250 km orbit from which rendezvous maneuvers began. Discovery docked with the ISS at 22:12 GMT on December 11. In the most demanding ISS assembly mission ever, the crew would require an additional spacewalk to complete installation of the P5 truss, retraction of the recalcitrant port P6 solar array wing, and activation of the truss electrical and cooling system. Sunita Williams rode the shuttle to the station, and remained behind with the EO-14 crew; ESA astronaut Thomas Reiter, already aboard the station, was returned to earth. Due to weather problems a landing at White Sands was considered; but in the end Discovery landed safely at Kennedy Space Center, after which it was to enter a year-long overhaul cycle.
Main mission objectives were delivery of the Harmony module to the station, and external work to move the P6 truss to its final location and put the ISS into its full-power configuration for the first time. Discovery docked with the ISS at the Destiny module at 12:40 GMT on 25 October. The cargo of 17,390 kg was as follows:
Discovery delivered to the International Space Station the Kibo Pressurized Module, the primary element of the Japanese portion of the station. Half an earth away from jettison of external tank ET-128, a 76 m/s OMS-2 burn at 21:40 GMT put the Shuttle in its low-altitude chase lorbit. Discovery docked at the PMA-2 port of the station at 18:03 GMT on 2 June. Using the shuttle and station's robotic arms, with assistance from spacewalking astronauts, the Kibo module was attached to the station's Harmony module at 23:01 GMT on 4 June. The previously-delivered Japanese Logistics Module was transferred from Harmony to Kibo on 6 June at 20:04 GMT. The Shuttle undocked from the station on 11 June at GMT and landed on 14 June at 15:15 GMT at the Kennedy Space Center.
Crew: Sturckow, Ford, Forrester, Hernandez, Fuglesang, Olivas. Deliver to the ISS and install the Multi-Purpose Logistics Module (MPLM); Lightweight Multi-Purpose Experiment Support Structure Carrier (LMC); Three-crew quarters, galley, and second treadmill (TVIS2); and the Crew Health Care System 2 (CHeCS 2).
Final flight of the space shuttle Discovery. The spaceplane docked with the International Space Station at 19:14 GMT on 26 February. The ELC-4 Express Logistics Carrier 4 was transferred from the Shuttle to the S3 station truss on 27 February. The station's SSRMS robot arm moved the Leonardo Permanent Multipurpose Module from the shuttle to the nadir port of the Unity module between 13:46 and 15:05 UTC on 1 March. Following cargo unloading and three spacewalks devoted to station repair and assembly, Discovery undocked from the station for the last time at 12:00 GMT on 7 March, landing at the Kennedy Space Center at 16:57 GMT on 9 March.
