I was looking at some galaxy information in Stellarium last night with my son when I noticed the ISS pop up over the horizon. I’ve never seen it before, so we rushed outside to watch it pass overhead and were treated to far more. Discovery had just undocked from the ISS and started its journey home and we were treated to a view of the shuttle leading the ISS by a few seconds across the entire sky. Fantastic to see, and all the more poignant because it is planned to be the last trip Discovery will make.
Shame I didn’t have a suitable camera and scope set up, but we were lucky to notice it happening in the first place.
