There's going to be a lot of traffic in outer space:  NASA Science News says:

Something special is happening this weekend. Venus and the Moon are gathering for a sunset conjunction on Saturday and Sunday, May 15th and 16th. On the same nights, the ISS is going to be flying over many US towns and cities. And if space shuttle Atlantis launches on schedule–wow! People could witness a rare meeting of the shuttle, station, Venus and the Moon. Details and observing tips may be found in today's story from Science@NASA.

Locally, we'll have opportunities for two ISS flyovers: May 15 @ 9:38 AM (49 degrees) and May 16 @ 8:28 PM (32 degrees).  The shuttle launch is scheduled for 11:20 AM today.  The 17th (8:52 PM) and 19th (8:07 PM) should have a good viewing of the ISS with Atlantis docked if all goes well.
