A prototype module for a private space station has passed an orbital milestone after completing its 10,000th trip around the Earth.

The crew of the space shuttle Discovery successfully completed a dress rehearsal today for their upcoming launch. They capped off their practice run at Cape Canaveral with a simulated countdown to liftoff at 11:00 a.m. ET.

If you live in the Northern Hemisphere you only need to look overhead and toward the north where you will find the seven bright stars that comprise the famous Big Dipper.

Data-recovery specialist Jon Edwards may have set a new standard: He found information on a melted disk drive that fell from the sky when space shuttle Columbia disintegrated in 2003.
