Expedition 7 Crew

Expedition 7 Commander Yuri Malenchenko and NASA International Space Station Science Officer Ed Lu today wrapped up a busy week of station and science activities as they approached the end of their eighth week on the ISS. Lu performed another run of the InSPACE experiment in the Microgravity Science Glovebox while Malenchenko spent some time loading the Progress 10, docked to the rear of the Zvezda Service Module, with station discards.

InSPACE stands for Investigating the Structure of Paramagnetic Aggregates from Colloidal Emulsions. The experiment, in the U.S. laboratory Destiny, looks at fluids that contain small particles that can be magnetized. The research could result in improved brake or vibration dampening fluids, or even improved systems to make buildings better able to survive earthquakes.

Malenchenko spent part of today loading the Progress 10 unpiloted supply craft docked to the aft port of Zvezda with ISS discards. With its load of trash, that progress will be undocked in October and burn up in the Earth’s atmosphere. A similar craft, Progress 11, arrived at one of the Zarya docking ports on June 11 and crewmembers have worked to unload it.

Lu and Malenchenko on Monday and Wednesday replaced the flexpacks in the canisters of the resistive exercise device (RED). The flexpacks provide the resistance as crewmembers exercise major muscle groups. The new flexpacks were brought up on Progress 11.

Tuesday Lu calibrated an ultrasound device and downlinked ultrasound images from the instrument in the Human Research Facility, a rack in the U.S. laboratory. Malenchenko did maintenance on the Zarya module’s cooling system, replacing a pump in one of the cooling loops.

Medical tests continued throughout much of the week. On Wednesday Lu set up and calibrated the Portable Clinical Blood Analyzer (PCBA). The next day each crewmember performed health status checks on one another using a variety of equipment, including the PCBA.

The two crewmembers talked on Tuesday with reporter Stephen Young of Wednesday they held a ship-to-ship chat with the six-member Aquarius crew of the NASA Extreme Environment Mission Operations (NEEMO). Peggy Whitson, the first NASA ISS science officer, who flew on ISS Expedition 5 from June to November 2002, commands the Aquarius crew. And on Thursday they talked with people from the NASAexplorers website at NASA’s Marshall Space Flight Center in Huntsville, Ala.

Saturday and Sunday will be days off, though exercise and necessary station maintenance will be performed both days. On Sunday they will have a chance to talk with their families in private family conferences. Another InSPACE run is scheduled for Monday, as is data transfer with the EXPRESS Rack 1 in the Destiny laboratory.

The next ISS status report will be issued on Thursday, July 3, or earlier, if events warrant.
