Work on the International Space Station this week started out with a spacewalk, moved back inside with extensive laboratory research work, and wound up with a series of maintenance tasks before the Expedition 5 crew began a long holiday weekend.

Commander Valery Korzun and Flight Engineer Sergei Treschev completed a 5-hour, 21-minute spacewalk Monday morning, swapping out Japanese space exposure experiments and a Russian experiment measuring jet thruster residue on the shell of the Zvezda Service Module. Flight Engineer Peggy Whitson kept everything running smoothly and helped coordinate her crewmates' activities from inside. She also helped take post-spacewalk readings on how her crewmates' lungs were functioning after working in the lowered pressure of their spacesuits, part of an ongoing study.

Then research took center stage again as Whitson cleaned up the Microgravity Science Glovebox and prepared it to resume experiments studying semiconductor formation in space. After a recent fifth experiment run, a quartz sample tube broke inside the glovebox enclosure. Whitson used a vacuum tube and fan system to remove and secure any particles left inside the box.

Whitson also downlinked a video tour of the U.S. Destiny laboratory module for NASA's Marshall Space Flight Center, where station research is coordinated by the Payload Operations Control Center. Whitson highlighted some of the two dozen experiments that she and her crewmates have been conducting during their first three months in orbit. Thirteen of the 24 phone booth-sized racks inside Destiny are dedicated to science investigations including a wide variety of experiments in human life sciences, physical sciences, commercial space product development and Earth observation, as well as education and technology demonstrations.

Friday, Whitson worked in the Quest airlock module, servicing the American spacesuits and recharging their batteries to prepare for upcoming tests next week. She also partially removed the Express 2 experiment rack in Destiny to gain access and replace a balky smoke detector before the crew began a three-day break over the Labor Day holiday.
