No. Date Together with Time Main tasks and notes
 1  10.07.2008  O. Kononenko  6h 18m
Inspection of the Soyuz TMA-12 spacecraft, checking the five locks that attach the return module to the propulsion module, and retrieve a suspect pyrotechnic bolt for inspection by engineers on the ground. They also installed a docking target for a new Russian module scheduled for launch late summer 2009.
 2  15.07.2008  O. Kononenko  5h 54m
Removing and installing science experiments. They also installed rendezvous equipment for a new Russian module scheduled for launch late summer 2009.
 3  03.08.2011  A. Samokutyayev  6h 23m
Moving a small crane, installing a communications terminal and removing and inspect antennas. Other tasks included installing a materials science experiment and deploying a micro-satellite.
 4  03.02.2016  Y. Malenchenko  4h 45m
The spacewalkers performed works with the experiment Test at two locations: they took away samples from the outer surface of the docking compartment Pirs hatch and in the area of the cover window #8 at the service module Zvezda. Goal of the experiments is to develop methods for detecting leaks and control of elements of the exterior surface of the ISS.
The cosmonauts also dismantled a monoblock responsible for exposing samples of organic and biological materials in open space (experiment Expose-R) and set the unit samples #2 from an experiment for the study of space influence on the mechanical properties of materials. At the same module, they had to replace a removable cassette container, where the samples are placed of the exterior of stations in conditions of prolonged exposure, change the orientation of the pressure control unit on the module Poisk.
One of the important tasks were works on an experiment with the goal to develop technologies for sticking film thermal control coating, secure package screen-vacuum thermal insulation on the surface to be repaired and transactions that require bonding film materials in space flight.
For more convenient travel on the outer surface of the ISS the spacewalkers installed handrails on the soft part of the conical device of the Functional Cargo Block Zarya. Upon completion of the main tasks the cosmonauts started a photo documentation of the external surface of the ISS Russian segment.
