This weekend at the #ESAOpenDay, @pmisson, Stefanie Riel, and I presented the scientific work that is done with #Astronaut photographs from the #ISS and #NighttimeLights research in general.
We were very happy to have had two #ESA astronauts stop by for an hour, to help us tell the public about their work: Thomas Reiter and John McFall (pictured)!
Thanks for a great event ESA, and thanks to everyone who stopped by our stand!
