For those interested.....
The space shuttle and ISS will be available for viewing by the naked eye tonight as they pass over North America.
Last night they flew over at 11:04pm my time. It was pretty awesome, you could see the two separated. While they only look like bright stars going by it is pretty cool being able to see them fly by at 18,000mph.
They go by tonight at 9:52 CDT my time. It only lasts for a couple minutes. Here's a link to viewing times and where to look in you're area if you're interested.
