Just saw your link! Going to go out tonight with the kids and try to see both - they are going to be only 2 minutes apart where I am (as the ISS goes out of view the Shuttle should come into view!). :)
It’s SO cool to see. Be ready for the night when the shuttle undocks to come home. You might have a night or two of seeing the ISS fly over first and the shuttle trailing a few degrees behind it.
