The engines of the Zvezda service module fired for a two-minute, 49-second reboost of the International Space Station’s orbit Thursday in a maneuver originally planned for next week. The maneuver was performed at 12:45 p.m. EDT and raised the orbiting laboratory’s altitude by 4.7 kilometers, or 2.9 miles.

The reboost was performed early so that it could double as a debris avoidance maneuver. The altitude increase avoided a four-inch-diameter piece of Russian rocket body launched in December 1991. Another reboost is being planned for Oct. 19 or 20 to complete the process of putting the station at the proper altitude for the docking of the ISS Progress 45 cargo craft, which is scheduled for launch Oct. 30.

Meanwhile, the Expedition 29 crew living and working aboard the station performed a variety of scientific research, cargo transfers and maintenance activities Thursday.

Commander Mike Fossum replaced and reconfigured equipment inside the Combustion Integrated Rack (CIR) and the Fluids Integrated Rack (FIR) which are part of the Fluids and Combustion Facility inside the Destiny laboratory. The pair of facilities help researchers study how fluids and flames react in the microgravity environment aboard the station and can be operated by crew members or remotely by researchers on Earth.

Flight Engineers Sergei Volkov and Satoshi Furukawa gathered and stowed unneeded equipment and hardware for disposal on the ISS Progress 42 spacecraft. The resupply vehicle is scheduled to undock from the station on Oct. 29 for a destructive re-entry into Earth’s atmosphere.

Volkov also had some time set aside to participate in a variety of scientific research including the Russian Uragan Earth observation program that studies natural and man-made disasters from space. He also worked with the Russian Plants-2 experiment, which researches the growth and development of plants under spaceflight conditions in a special greenhouse facility.

Furukawa prepared support equipment for the activation of the Multipurpose Small Payload Rack in the Kibo laboratory. He also worked with the CGBA-4 (Commercial Generic Bioprocessing Apparatus 4) and CGBA-5 payloads in their EXPRESS Racks, performing inspection and maintenance.
