That was smooth!
Tons of us collected to view the stream and the control room from the bridge. A textbook launch, that was. Mission operations have also just confirmed separation.

Chairman Woerner has just announced that first signal (AOS) was just received through the Troll ground station in the Antarctic!
Michael Schmidhuber has posted a quick one on the German-language pages. There are great pictures of him standing on a chair, watching the launch with binoculars in one hand (the MCC in Baikonur is 7.8 km from the silo) and a telephone receiver in the other. Check them out. He has also posted a couple of pictures of the cloud formations after separation of the first stage. A bit of party time today and the DLR team flies back on Tuesday.
We will come back with more information when we can. In the meantime, check in at @DLR_en on Twitter.
