Expedition 7 Crew

The International Space Station's Expedition 7 crewmembers concentrated
on Station upgrades and routine maintenance during their 11th week on
orbit. Commander Yuri Malenchenko and NASA ISS Science Officer Ed Lu
also advanced the research in several laboratory experiments during the
week and shared their experiences in both formal and informal settings. 

In the Russian segment of the Station, Malenchenko installed a
refurbished component of the Satellite Navigation System and new pipe
conduits in the condensate separation and pumping unit; all of that
hardware was delivered to the ISS last month on a Russian resupply
craft. The crewmembers upgraded a relay unit in the Russian audio system
which enables module-to-module "telephone" calls; completed inspections
of life support systems, smoke detectors and microbe filters throughout
the Station; rebuilt and restored laptop computer hard disk drives; and
audited supplies to help mission managers decide what to launch on
upcoming Progress resupply ships. 

The presence of a crew on orbit supplies test subjects for human life
sciences research into how people respond to long periods in the absence
of gravity, and this week Malenchenko and Lu gathered data for U.S. and
Russian experiments gauging their health in microgravity. They also
completed two hours or more of exercise each day to maintain their
muscle tone and cardiovascular fitness. 

Last weekend Lu set up an electronic still camera in the Earth-facing
window of the Destiny Laboratory for another session of the EarthKAM
experiment (Earth Knowledge Acquired by Middle Schools). In this
experiment, students in grades six through eight study Earth geography
and orbital mechanics to understand when Station will be over a
particular spot on Earth, and then submit requests that are uplinked to
the on-board computer that controls the camera. The students later study
the photos "they took" of the Earth from an altitude of more than 240
miles; more than 300 such photos were taken during this week's

Malenchenko and Lu took time throughout the week to share the experience
of ISS. On Monday they used the Station's amateur radio system to answer
questions from participants in the Euro Space Center Space Camp in
Belgium, and sent a message of greeting and encouragement for a Space
Day event at ceremonies commemorating the 65th anniversary of the city
of Korolev, home of the Russian Mission Control Center. Tuesday they
chatted with Japanese middle school students at the "Tokyo FM" Radio
Network station, and on Thursday they discussed the mission with a
reporter from the Voice of America. Today they talked with the winners
of a Russian school science contest. 

Information on the crew's activities aboard the Space Station, future
launch dates, as well as Station sighting opportunities from anywhere on
the Earth, is available on the Internet at: 


Details on Station science operations can be found on an Internet site

Flight Center in Huntsville, Ala., at: 


The next ISS status report will be issued on Friday, July 18, or sooner
if events warrant.
