Mission overview[edit]

Three Russian cosmonauts, two American and one Japanese astronauts made up the Expedition 23 crew. It was the first ISS crew to include three Russians at once.[4] The Expedition 23 crew continued outfitting the newest modules of the nearly completed space station. The crew welcomed the shuttle flight STS-131 in April 2010. The Expedition 23 crew also saw the arrival of the Rasvet Russian docking module (MRM1) aboard Space Shuttle Atlantis on STS-132, which launched on 14 May 2010.
