Departing from my tech theme, I had to share this. This footage is so clear, and not just some blurry dot in the sky. This footage was captured by crew members on board the current Shuttle Mission, STS-120, after jettisoning the External Fuel tank. They use handheld cams to capture this footage for analysis of the tank, probably after previous well known incidents of damage. If you dont want to watch the whole thing, fast forward to 2 mins 20 seconds to see what the talk is about!
