 1  15.11.2010  F. Yurchikhin  6h 27m
Installing a multipurpose workstation on the starboard side of the Zvezda service module’s large-diameter section, cleaning thermal insulation around the vents for the Elektron oxygen-generation system and relocating 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).
 2  21.01.2011  D. Kondratiyev  5h 23m
Completing installation of a new high-speed data transmission system, removing an old plasma pulse experiment, installing a camera for the new Rassvet docking module and retrieving a materials exposure package.
 3  16.02.2011  D. Kondratiyev  4h 51m
Installing two experiments. One will collect information useful in seismic forecasts and earthquake predictions, and the second will look at gamma splashes and optical radiation during terrestrial lightning and thunderstorms. The spacewalkers also retrieved a pair of panels exposed to space as part of an experiment to identify the best materials for building long-duration spacecraft. The cosmonauts also deployed an experiment called ARISSat-1, or Radioskaf-V, a boxy 57-pound nanosatellite that houses congratulatory messages commemorating the 50th anniversary of Yuri Gagarin's launch to become the first human in space.
