STS-105 - .
Call Sign: Discovery. Crew: Horowitz; Sturckow; Barry; Forrester; Culbertson; Dezhurov; Tyurin. Payload: Discovery F30 / Leonardo. Mass: 116,914 kg (257,751 lb). Nation: USA. Related Persons: Horowitz; Sturckow; Barry; Forrester; Culbertson; Dezhurov; Tyurin. Agency: NASA Houston. Manufacturer: Boeing. Program: ISS. Class: Manned. Type: Manned spaceplane. Flight: STS-105; ISS EO-3. Spacecraft: Discovery. Duration: 11.88 days. Decay Date: 2001-08-22 . USAF Sat Cat: 26888 . COSPAR: 2001-035A. Apogee: 402 km (249 mi). Perigee: 373 km (231 mi). Inclination: 51.6000 deg. Period: 92.30 min. 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:
STS-105 main engine cutoff was at 2118 GMT placed Discovery and external tank ET-110 into a 58 x 234 km x 51.6 deg orbit. At 2148 GMT Discovery reached apogee and fired its OMS engines to enter a 155 x 233 km x 51.6 deg orbit; another burn at 0100 GMT raised the orbit to 198 x 277 km. Discovery docked at the Station's PMA-2 port at 1842 GMT on August 12. After some problems aligning the docking system, the docking ring was retracted and latched at 1905 GMT and the hatch was opened to ISS at 2042 GMT. Expedition 3 began on August 13 at 1915 GMT when the new crew's seat liners were installed on the Soyuz transport ship. The formal EX-2/EX-3 change-of-command ceremony was held on August 17 in Destiny.
- Bay 1-2: Orbiter Docking System/External Airlock and 3 EMU spacesuits - 2160 kg
- Bay 4P: Adapter beam with G-780 (Mayo High School, Rochester, Minnesota experiment to study germination of faba beans) and PSP-1 (NASA-GSFC canister with passive experiments and ballast) - 200 kg
- Bay 5: Integrated Cargo Carrier/KYD - 1280 kg, with the Early Ammonia Servicer for the station's P6 truss- 640 kg and two small exposure experiments PEC-1 and PEC-2, to be installed on the be installed on the ISS Quest module as part of the MISSE materials exposure program
- Bay 7-12: MPLM FM1 (Leonardo) module - 9800 kg total including 3300 kg of payload to be transferred to the Station
- Bay 13P: Adapter beam with G-774 (Microgravity Smoldering Combustion (MSC) experiment) and SEM-10 (canister with 11 school experiments) - 410 kg
- Bay 13S: Adapter beam with Simplesat and ACE avionics - 355 kg
- Sill: RMS arm - 410 kg
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.
