You don't get to meet an astronaut every day

This weekend I was invited to attend ESA's and DLR's #SocialSpace tweetup in Cologne, Germany, organised in the context of the German Aerospace Day.

I will post a more elaborate photo report of this very fine and interesting meeting later this week, but for the moment I want to show you the picture below: Dutch ESA astronaut André Kuipers, who went to space in 2004 and 2012, was so kind to pose with me for a picture.
