Expedition 7 Crew

The Expedition 7 crew, Commander Yuri Malenchenko and NASA ISS Science
Officer Ed Lu, wound up a busy week with a Canadarm2 session that could
lead to operation of the Station's robotic arm by controllers on the
ground without crew participation. 

Today's activity, with Lu working with flight controllers in Houston,
began a little after 3 a.m. CDT. It was a feasibility study. Lu
performed task the ground cannot yet do - operating the latching end
effector and initiating joint motion, for example. The task was
completed successfully before 7 a.m. Results will be used in validation
of the concept and in determining software, hardware or procedural
changes that would be needed for arm control from the ground. 

Lu also spent some time working with the Coarsening in Solid Liquid
Mixtures (CSLM) experiment's sample processing units (SPUs) in the
Microgravity Science Glovebox of the U.S. laboratory Destiny. One unit
Lu installed was found to be distorted, so he reinstalled the previous
SPU. The CSLM experiment was delayed from early in the week because of
internal humidity and dew point concerns. The experiment is expected to
begin next week. It will study "coarsening" during which the strength of
a material is reduced. This phenomenon is seen in many materials,
including water droplets in rain clouds and dental fillings. It can
weaken high-temperature turbine blades. Meanwhile, Malenchenko worked
for more than two hours to load discarded items into the Progress 10
unpiloted cargo craft docked at the rear of the Zvezda Service Module. 

Last Monday the crew focused on medical experiments and an inventory by
Malenchenko of 44 Russian medical, food supplement and ointment kits,
about a two-hour task. Tuesday saw additional medical tests and Mission
Control Moscow continued testing a new satellite navigation system
antenna. Both crewmembers took time to answer questions from elementary,
middle and high school students relayed to them by educators at Kennedy
Space Center. 

After Soyuz descent training and continued work with the week-long
process of space suit batteries conditioning Wednesday, Lu and
Malenchenko on Thursday prepared for today's robotic operations and
Malenchenko continued participation in a Russian study of bioelectrical
heart activity while at rest. 

Throughout the week both crewmembers continued regular maintenance
activities on the Station, and performed their daily exercise sessions,
designed to ward off the effects of lengthy exposure to the microgravity
environment of the orbiting laboratory. 

NASA announced on Friday that astronaut Michael Foale and Cosmonaut
Alexander Kaleri will be the Expedition 8 crew of the International
Space Station. They are scheduled to launch on a Russian Soyuz
spacecraft with European Space Agency astronaut Pedro Duque of Spain on
Oct. 18. Duque will return to Earth with the Expedition 7 crew, which
arrived at the station April 28. Their Soyuz is scheduled to land in
Kazakhstan Oct. 28.

dates and Station sighting opportunities from anywhere on Earth is

The next ISS status report will be issued on Friday, Aug. 1, or sooner
if events warrant.
