• How to avoid a falling satellite. CNET's William Harwood wrote, "Experts expect more than two dozen chunks of debris to survive re-entry and hit the ground in a 500-mile-long footprint somewhere along the satellite's orbital track. But given the bus-size 6.3-ton's satellite's trajectory and the vast areas of ocean and sparsely populated areas UARS passes over, experts say it is unlikely any falling debris will result in injuries or significant property damage." And even though you're very unlikely to get hit by falling space junk, CNET contributor Eric Mack tells us how to track the doomed hardware just in case.
