Mission objectives

Expedition 8 Commander and NASA Station Science Officer Michael Foale, Flight Engineer Alexander Kaleri and ESA Astronaut Pedro Duque docked the Soyuz TMA-3 with the International Space Station at 07:15:58 UTC on 20 October 2003. At the time of docking, both spacecraft orbited the Earth above Russia.

Once the Expedition 7 crew undocked, Foale and Kaleri settled down to work, beginning a more than six-month stint focused on Station operations and maintenance.

The new Station crew, along with Duque, launched from the Baikonur Cosmodrome in Kazakhstan at 05:38:03 UTC, on 18 October 2003.

Spacewalks

The Expedition 8 crew conducted the first two-person spacewalk at the International Space Station. Unlike previous spacewalks conducted by ISS crews, there was not a crewmember inside the Station as the spacewalkers worked outside. The spacewalk was based out of the Pirs docking compartment; the spacewalkers wore Russian Orlan space suits.

This was the 52nd spacewalk devoted to Space Station assembly, operations and maintenance, bringing the cumulative total to 322 hours and 32 minutes. It was the 27th based out of the Station, bringing the total to 155 hours and 17 minutes.

	This spacewalk was cut short due a cooling system malfunction in Kaleri's spacesuit. Although the spacewalk ended early, Foale and Kaleri were able to complete a number of their tasks. The first task was the replacement of cassette containers that hold sample materials for an experiment studying the effect of long-duration exposure to the microgravity environment. Later, Foale replaced two similar cassettes housed on the outside of the Zvezda Service Module. A Russian experiment named Matryoshka was attached to the outer hull of Zvezda which will provide data on radiation exposure to the human body during space flight. The spacewalkers also removed one of the suitcase-sized devices associated with the Japanese Aerospace Exploration Agency's MPAC-SEEDS experiment. They relocated a second device. This experiment was studying micro-meteor impacts and material exposure in the space environment. This experiment was installed on the ISS by Expedition 3 spacewalkers 15 October 2001. The crew was not able to complete the removal of laser light retroreflector devices from the aft end of Zvezda. The reflectors were being studied as navigation devices for the European Space Agency's Automated Transfer Vehicle, which first flew to the ISS in 2008. Another task not included was work on a materials science experiment called Kromka. This experiment measured the amount of residue emitted from Zvezda's jet thruster firings. Foale and Kaleri departed the station for earth aboard the Soyuz TMA-3 spacecraft on 29 April 2004 along with ESA Astronaut André Kuipers, who had arrived with the Expedition 9 crew aboard Soyuz TMA-4 nine days earlier.
