SOFIA - The airborne infrared observatory
'Encounter' a satellite in orbit, view the Moon and the Rhine Valley in 3D, board SOFIA, the airborne observatory, or visit the wind tunnel or astronaut training facility to experience the extreme conditions to which materials and people are exposed in space – these are just a few of the many space-related activities that DLR in Cologne will make available to the general public on 18 September 2011.
