Tim (daox) is going to laugh when he reads this...
I'm enough of a nerd I'm going to tell everyone who might be interested: the International Space Station is streaming live video 24 hours a day (where there's coverage - it seems to drop out over parts of Asia, the Indian Ocean & some of the middle east).
You can view it from
NASA's TV page, in combination with this live, updating Google map showing the ISS position over the ground (or water) in real time:
LIVE REAL TIME SATELLITE AND SPACE SHUTTLE TRACKING
When the space dudes on board are working during the day (I'm guessing they keep to Florida time), they turn the camera towards the inside of the ISS. But most of the time it seems to be pointed out a window at the Earth screaming past about 350 km below at ~28,000 km/h (about 4.5 mi./sec).
To me this ranks up there as one of the coolest things I've seen online.
Above: screen grab from a few minutes ago. ISS is scooting along below Australia (hi Pete!). When it goes over land you can easily pick out major features.
There are also sites that let you look up when the ISS will be (easily) visible in your location (usually just after dusk, or before dawn). I'm looking forward to showing my nieces & nephews the web sites, tracking the station as it moves over the west coast, into dusk and then going outside to spot it flying overhead.
