Unique spacecraft viewing opportunity tonight (7/28)
 

Folks in North America who look up at the night sky in the right place at the right time tonight will have a unique opportunity to see three spacecraft flying overhead in orbit some 200+ miles above the planet: the International Space Station, space shuttle Endeavour, and an an unmanned Progress supply ship, all traveling along the same arc across the sky. They should be very easy to spot... I've seen ISS from downtown San Antonio; it's bright enough to appear clearly despite all the city lights.

Fine out when and where to look by going to Human Space Flight (HSF) - Realtime Data -- pick your country, state and city, and note the time and direction of approach provided there (in my case, it's a three-minute flyover starting at 9:15pm going from NNW to SE). There's a total of 13 people up there, and you'll get a good idea of what 17,500mph looks like.
