ISS: Expedition 26

Launch from the Baikonur Cosmodrome (Dmitri Kondratiyev, Paolo Nespoli and Catherine Coleman with Soyuz TMA-20). Scott Kelly, Aleksandr Kaleri and Oleg Skripochka were onboard since October 10, 2010 (arrival with Soyuz TMA-01M).

The first EVA by Dmitri Kondratiyev and Oleg Skripochka occured on January 21, 2011 (5h 23m) to complete installation of a new high-speed data transmission system, remove an old plasma pulse experiment, install a camera for the new Rassvet docking module and retrieve a materials exposure package.

On January 27, 2011 the Japanese cargo module HTV-2 "Kounotori2" arrived at the International Space Station and was attached by Catherine Coleman and Paolo Nespoli using the station's Canadarm2 robotic arm.

The second and final EVA was performed again by Dmitri Kondratiyev and Oleg Skripochka on February 16, 2011 (4h 51m) to install 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 Gagarins launch to become the first human in space.

On February 24, 2011 the European cargo module ATV-2 "Johannes Kepler" arrived at the International Space Station.

STS-133 (February 26, - March 09, 2011) transported several items to the space station, including the Permanent Multipurpose Module Leonardo, which was left permanently docked to one of the station's ports. The shuttle also carried the third of four ExPRESS Logistics Carriers to the ISS, as well as a humanoid robot called Robonaut.
