International Space Station Status Report #03-39

Expedition 7 Crew

Aboard the International Space Station, Expedition 7 Commander Yuri
Malenchenko and NASA Science Officer Ed Lu studied their first sample in
an experiment designed to look at how air bubbles can weaken metals,
crystals and other materials as they coalesce on orbit. They also packed
a resupply craft full of trash and readied it for departure next week. 

Today marked the crew's 118th day on orbit. Sample processing for the
Pore Formation and Mobility Investigation (PFMI) concluded today after
beginning Wednesday inside the U.S. laboratory Destiny and the
protective environment of the Microgravity Science Glovebox. Processing
of the first Expedition 7 sample had been postponed from the previous
week due to a missing data cable. Lu found the cable after he talked
with former Station Science Officer Don Pettit via cell phone. Plans
call for Lu to process seven more samples. 

Malenchenko participated in his fifth session with a Russian heart
experiment, Study of the Bioelectric Activity of the Heart at Rest, with
Lu assisting as crew medical officer and administering the
electrocardiogram. Lu also performed periodic health tests with a
portable clinical blood analyzer. 

"The crew is in great spirits and looking forward to a busy week of
departures and arrivals next week," said Expedition 7 Lead Flight
Director John McCullough. 

As the crew exhausted the supply of oxygen from the Progress 10 cargo
vehicle docked to the back of the Zvezda Service Module to repressurize
the Station, they continued filling it with trash and worn-out
equipment. The old Progress is scheduled to undock from Zvezda at 5:43
p.m. CDT Aug. 27, and later will be commanded to re-enter and burn up in
the Earth's atmosphere. That undocking will vacate a port for the
Progress 12 vehicle that is scheduled to launch from the Baikonur
Cosmodrome in Kazakhstan at 8:48p.m. CDT Aug. 28, and dock to Zvezda at
10:43p.m. CDT Aug. 30. Progress 12 will deliver about 1,000 pounds of
food, supplies and equipment for use on the Station. 

Early next month, the Progress 11 resupply craft will depart its Pirs
docking compartment moorings to make room for the Soyuz TMA-3 spacecraft
that will ferry the Expedition 8 crew and European Space Agency
astronaut Pedro Duque of Spain to the Station on Oct. 20. Expedition 8
Commander Michael Foale and Russian cosmonaut Alexander Kaleri will
replace the Expedition 7 crew, which will return to Earth Oct. 28 with
Duque after he completes more than a week of science activities.

future launch dates and Station sighting opportunities from anywhere on
Earth is available at:

The next ISS status report will be issued following the Progress 10
undocking Aug. 27, or sooner if events warrant.
