Space history: The first European laboratory dedicated to long-term experimentation in weightlessness

Since being attached to the Harmony (Node 2) module a few days later on 11 February, Columbus is now an integral part of the International Space Station (ISS), bringing years of organisation and hard work to fruition.

With a projected 10 years in orbit, Columbus creates space history as the first European laboratory dedicated to long-term experimentation in weightlessness.
 
ESA astronauts Léopold Eyharts from France and Hans Schlegel from Germany were crewmembers on the Columbus assembly and commissioning mission. They joined five NASA colleagues on the STS-122 Shuttle flight.

The Columbus Mission had two phases:

1. The 13-day STS-122 flight (also known as the 1E assembly mission) to attach the European laboratory to the ISS, and thereafter activate, and begin commissioning of the laboratory. This included the attachment of European external experiment facilities and additional assembly/maintenance tasks.

2. After the undocking of STS-122, Léopold Eyharts remained on the Station for nearly 7 weeks as a member of the ISS Expedition 16 crew.

   Eyharts continued Columbus commissioning activities, completing the activation of the internal experiment facilities as well as undertaking European scientific, public relations and educational activities and additional activities in his role as ISS Flight Engineer 2.

   Eyharts returned to Earth with Space Shuttle Endeavour (STS-123 mission) on 27 March 2008 after nearly 49 days in space.
