Expedition Report

Launch from the Baikonur Cosmodrome (Aleksandr Kaleri, Oleg Skripochka and Scott Kelly with Soyuz TMA-01M). Fyodor Yurchikhin, Shannon Walker and Douglas Wheelock were onboard since June 17, 2010 (arrival with Soyuz TMA-19).

The Russian resupply spacecraft Progress M-05M, which came to the station in May 2010, was undocked on October 25, 2010 to make room for another resupply spacecraft - Progress M-08M.

On October 26, 2010, the space station performed a Debris Avoidance Maneuver (DAM) in order to get out of the way of a piece of debris from the defunct Upper Atmosphere Research Satellite (UARS).

Progress M-08M was launched from the Baikonur Cosmodrome's Pad 1 (Gagarin's launch pad) at 15:11:50 UTC on October 27, 2010. On October 30, 2010 after three days of autonomous flight following the launch, Progress M-08M docked with the Pirs Docking Compartment Module nadir port of the space station. The successful linkup came at 16:36 UTC while flying 220 miles over western Kazakhstan. In preparation for the docking on October 20, 2010, the engines of the Progress M-07M spacecraft were fired for 228.7 seconds. This reboost placed the space station at the proper altitude to receive Progress M-08M. A late DAM performed on October 26, 2010 sightly changed the station's orientation in space and the planned docking had to be brought forward by a couple of minutes. The Progress M-08M spacecraft, flying on autopilot, performed a flawless rendezvous with the space station. After arriving in the vicinity of the space station, Progress M-08M began a flyaround maneuver to get lined up with the docking port and then executed a roll maneuver to properly orient its solar wings with surrounding structures around the Pirs module. A brief stationkeeping hold with about 650 feet between the spacecraft and space station allowed Russian flight controllers to assess systems before giving approval to commence the final approach. During stationkeeping, flight controllers in Moscow instructed cosmonaut Aleksandr Kaleri to activate the TORU manual docking equipment and take over the piloting tasks from the Progress' autonomous KURS system. The switch to manual mode was decided at range of 194 m. Aleksandr Kaleri worked inside the space station's Zvezda module to fly Progress M-08M remotely using television views and a pair of joysticks and guided it to the successful docking. The range rate at the time of contact, based on Mission Control Center-Moscow calculations was 0.067 m/s.
Progress M-08M hauled about 2.5 tons of cargo supplies including water, air, fuel and hardware for Molniya-Gamma and Coulomb Crystal experiments to the space station. The Molniya-Gamma experiment measures gamma splashes and optical radiation during terrestrial lightning and thunder conditions. The spacecraft also carried high-speed data transmission equipment to be installed on the outer surface of the space station during a spacewalk by cosmonauts Oleg Skripochka and Dmitri Kondratiyev in January 2011. In addition to the standard rations, the food boxes contain fresh fruits and vegetables - lemons, apples, onions, tomatoes, and 1 kg of garlic.
Progress M-08M spacecraft undocked nominally from the International Space Station on January 23, 2011. The undocking command was issued by Russian Mission Control at 00:40 UTC. The spacecraft was not used for further scientific experiments. The deorbit burn took place at 05:16 UTC on January 24, 2011. It re-entered and fell into a remote area of the southern Pacific Ocean at 06:07 UTC.

Space Shuttle Discovery on STS-133 mission was scheduled to arrive at the ISS on November 03, 2010 but was re-scheduled for launch on February 03, 2011. The 10th anniversary of human life, work and research on the ISS fell during Expedition 25.

The only EVA in this expedition was performed by Fyodor Yurchikhin and Oleg Skripochka on November 15, 2010 (6h 27m) to install a multipurpose workstation on the starboard side of the Zvezda service module’s large-diameter section, clean thermal insulation around the vents for the Elektron oxygen-generation system and relocate a television camera from one end of the Rassvet docking compartment to the other (failed due to interference with insulation where it was to be installed).
Fyodor Yurchikhin and Oleg Skripochka installed a portable multipurpose workstation in Plane IV in the Zvezda large diameter and installed struts between Poisk module and Zvezda module and Poisk module and Zarya module. They performed an experiment called Test, which was aimed at verifying the existence of micro organisms or contamination underneath insulation on the Russian segment of the ISS. Fyodor Yurchikhin and Oleg Skripochka photographed and installed the protective cover and disconnected and removed the Plasma Pulse Injector Science hardware from the portable multipurpose workstation in Plane II of the Zvezda. They cleaned the Kontur science hardware (ROKVISS) with dry towels and then disconnected and then removed it. Fyodor Yurchikhin and Oleg Skripochka also installed the protective cover and disconnected and removed the Expose-R scientific experiment from the portable multipurpose workstation in Plane II of the Zvezda module. The Kontur experiment studied remote object control capability for robotic arms and the Expose-R experiment is a European Space Agency experiment designed to expose organic material to the extreme environment of space. Fyodor Yurchikhin and Oleg Skripochka installed an oft hand-rail on Pirs docking module and installed the SKK #1-M2 cassette on Poisk module. The cosmonauts also removed a television camera from the Rassvet module, however they were unsuccessful in relocating the camera due to interference with insulation where it was to be installed.
