During the first spacewalk (Russian EVA #27) conducted on 21 January 2011  Kondratyev and cosmonaut Oleg Skripochka focused to complete installation of a new high-speed data transmission system.
Kondratyev was designated as Extravehicular 1, and had a red stripe on his spacesuit.
Kondratyev and Skripochka began the five-hour, 23-minute spacewalk at 9:29 a.m. EST when the two cosmonauts opened the Pirs hatch and began exiting the Russian segment of the space station.
The spacewalk ended at 2:52 p.m EST.
They deployed the antenna for the Radio Technical System for Information Transfer, an experimental system designed to enable large data files to be downlinked using radio technology at a speed of about 100 MB/s from space station's Russian segment.

During the spacewalk, Kondratyev and Skripochka also removed the plasma pulse generator on the port side of the Zvezda module that was part of an experiment to investigate disturbances and changes in the ionosphere from space station impulse plasma flow.
The generator, was covered, removed and returned inside the Pirs airlock.
They also removed the commercial Expose-R experiment from the port side of Zvezda.
The joint Russian and European Space Agency package contains a number of material samples that were left open to space conditions.
Working inside the Pirs airlock, Kondratyev and Skripochka grabbed the new docking camera for the Rassvet module (MRM1) and carried it to the worksite on Rassvet.
They installed the camera and mated the camera's cable to a pre-wired connector that will route the video into the space station.
