On February 16, 2011 Russian cosmonauts Dmitry Kondratiev and Oleg Skripochka (ISS Expedition 26 flight engineers) performed a spacewalk.

The EVA was performed via the Earth-facing "Pirs” Docking Compartment. This was the second spacewalk for Kondratiev, EV1, who was wearing an Orlan-MK spacesuit with red stripes and the third for Skripochka, EV2, who was wearing the blue-striped Orlan-MK suit.
Kondatiev and Skripocka beat their own record of January 21's EVA, when they returned to the station about 30 min ahead the schedule. On February 16, 2011 they spent in space 4 hours and 50 minutes instead of 6 hours planned.
During the spacewalk, the cosmonauts installed equipment for two experiments outside the Zvezda service module: Molniya-Gamma, to observe gamma splashes and optical radiation during thunderstorms on the Earth, and Radiometria, to gather data for seismic forecasts and earthquake predictions. Kondratyev and Skripochka also retrieved two Komplast panels from the exterior of the Zarya module. The panels contain materials exposed to space, and are part of a series of international experiments to find the best materials for constructing long-duration spacecraft.
