ISS Cities at Night

Thanks to astropixie for pointing this out - a cool video of still images taken from the ISS of cities around the world at night, narrated by astronaut Don Pettit. I saw Pettit present this video at ISDC 2007 in Dallas last May, so I'm happy to find it on the web now. He talked about how they had improvised the "barn door tracker" from spare parts found on board the space station, which allowed them to get very sharp time-exposed images (previous hand-held digital camera images had been very poor). The still image above is an example from 2003. It's London, where I will be heading on Friday for another business trip.
