Aboard the orbiting International Space Station on Friday, the Expedition 28 crew conducted research, did some post-shuttle mission reorganizing and prepared for an upcoming Russian spacewalk.

NASA Flight Engineer Mike Fossum participated in an experiment known as VO2 Max, which observes the aerobic capacity of an individual on a long-duration space mission. The experiment involves a graded exercise test using either a treadmill or exercise bike. By understanding the changes in aerobic capacity that occur within space flight, necessary adjustments can be made to spacewalk exercise countermeasures. Fossum will participate in a VO2 Max observation at least once every 30 days while he is on the station.

NASA Flight Engineer Ron Garan completed maintenance on a multipurpose small payload rack combustion chamber, used to perform research on how microgravity affects flames and other types of combustion.

Japan Aerospace Exploration Agency astronaut Satoshi Furukawa moved equipment associated with the Anomalous Long Term Effects on Astronauts Shield experiment, which looks at the effects of long-term exposure to radiation in the low-Earth orbit environment.

Station Commander Andrey Borisenko spent some time with the RUSALKA experiment. RUSALKA is a test of procedures for remote determination of methane and carbon dioxide content in the Earth’s atmosphere. He took pictures of the atmosphere using special camera filters and sent the information to researchers on Earth.

Borisenko teamed with Flight Engineers Alexander Samokutyaev and Sergei Volkov to prepare the Pirs docking compartment and airlock for the upcoming spacewalk by Samokutyaev and Volkov. The 29th Russian spacewalk is scheduled to begin 10:30 a.m. EDT Aug. 3, and will be broadcast live on NASA Television. The trio also teamed up for several maintenance duties including updating the station’s inventory.

Fossum joined Garan and Furukawa in cleaning up and organizing the Permanent Multipurpose Module after the delivery of supplies and spare parts by the crew of the STS-135 shuttle mission.

Space shuttle Atlantis landed for the final time of the Space Shuttle Program at 5:57 a.m. Thursday, after 200 orbits around Earth and a journey of 5,284,862 miles. Atlantis undocked from the station at 2:28 a.m. Tuesday.
