This reminds me of an experience I had in Joshua Tree one evening. The sun had just set and it was getting dark. I noticed two bright dots in the sky in close proximity to each-other. At first I thought "airliners", but had to rethink my hasty conclusion because the lights weren't blinking. I had to stop walking to really take in the scene: two very bright white dots in the eastern sky, about one closed fist at arm's length away from each other, moving across the sky slowly but consistently. Having observed ISS before I knew how bright it could be. This certainly seemed like another ISS sighting, but what was the other thing? Then I remembered: the shuttle had launched not too long ago for a mission to ISS. Could I have just witness the moments after undocking? I checked NASA's data as soon as I got home and sure enough the undocking time was just prior to my observation. This was among the last shuttle missions so I'll never forget that moment!
