ATV-5 docking refresher

Cosmonaut Sasha Skvortzov and ESA astronaut Alexander Gerst during a rehearsal of the docking Europe's cargo vessel ATV-5 on the International Space Station. Astronauts often do practice runs or take refresher courses in space.

Alexander and Sasha set up the command post that will monitor the approach and docking of Europe's largest spacecraft 8 July 2014, one month before the planned arrival of ATV-5.

During his six month Blue Dot mission Alexander will perform over 70 experiments.
