Expedition 2
Expedition 2 (also called ISS EO-2) was the second long-duration spaceflight aboard the International Space Station, immediately following Expedition 1. Its three-person crew stayed aboard the station from March to August 2001. In addition to station maintenance, the crew assisted in several station assembly missions, welcomed the first space tourist Dennis Tito, and conducted some scientific experiments.
The crew consisted of one Russian, commander Yury Usachev, and two American flight engineers Susan Helms and James Voss. The three had been to the station briefly in the previous year, during the 10-day mission STS-101 in May 2000.
The Expedition 2 crew was brought to the station aboard Space Shuttle Discovery during mission STS-102. The Expedition's increment began when Discovery docked on 10 March 2001, bringing Expedition 1 to an end. In addition to the Space Shuttle flights which brought the crew to and from the station, there were two visiting Space Shuttle missions and one Soyuz mission which docked with the ISS during Expedition Two. In August Discovery returned to rotate the long-duration crews again, bringing the crew of the next expedition. The Expedition 2 increment ended when Discovery undocked from the station on 20 August 2001.
All three crew members had visited the International Space Station together in May 2000 aboard STS-101. In addition to this spaceflight, the Expedition 2 Commander Yuri Usachev also had two other spaceflights, both of which were long-duration missions aboard Mir (EO-15 and EO-21).
In addition to STS-101, flight engineer Susan Helms had three other spaceflights, all of which were Space Shuttle missions (STS-54, STS-64, STS-78). James Voss also had three other spaceflights, all of which were Space Shuttle missions (STS-44, STS-53, STS-69).
Expedition 2, the second long-term crew for the International Space Station arrived in March 2001. They returned to Earth on mission STS-105, 22 August 2001 after having spent 163 days aboard the station and 167 days in space. Only Voss performed a spacewalk on STS-101, along with Jeffrey Williams.
During this expedition, research facilities launched to the Space Station included a Human Research Facility, two EXPRESS (Expedite the Processing of Experiments to the Space Station) Racks, one of which contains the Active Rack Isolation System and the Payload Equipment Restraint System. They also prepared the Destiny laboratory to enable upcoming experiments to be conducted.
A major focus was on gaining a better understanding of how to protect crew members from radiation while working and living in space. Radiation exposure in high doses over long periods of time can damage human cells and cause cancer or injury to the central nervous system.
