The coolest thing. I went to the planetarium in Rochester last weekend and they gave out pamphlets on when to watch for the ISS to pass over at night. I saw it two nights ago and watched it pass through the Big Dipper, then become very bright...brighter than a star in the sky...and pass over head at just the time the pamphlet said it would. Then tonight, they said the Space Shuttle was detaching and coming to Earth and I looked for it tonight and there were TWO of the same entities going across the sky at the same pace. Then the one that I assumed to be the SS flared bright for a second....I assume a rocket boost...and they both travelled off to the horizon together. We'll only be able to see the ISS pass overhead this summer for a couple more nights and then its orbit takes it over the horizon...but if you want to look to see where it is passing over your city, go to:

you can log in after you sign up and put in your town or city and click on ISS ten-day predictions and it will tell you if it will be passing over your coordinates any time in the next ten days. Really cool. If you like star watching/gazing, this is a truly awesome sight.
