Inside the Cupola of the International Space Station, Canadian astronaut Chris Hadfield, Expedition 34 flight engineer, sits in for a refresher session with the controls of the Canadian-built Space Station Remote Manipulator System or Canadarm2. In less than a week, the crew will receive a welcome visit by the SpaceX Dragon vehicle, which is scheduled to bring supplies up to the orbital outpost during the first week of March. After being docked to the station for several days, Dragon will return to Earth with a different batch of materials and hardware.
