NASA Satellite Expected To Collide With Earth

According to NASA, a retired U.S. research satellite the size of a school bus has been sucked into the Earth's gravitational pull. The space agency expects the satellite to break into pieces on entry to the atmosphere, and for some of those pieces — some as heavy as 300 pounds — to rain down later this week. Donald Kessler, who served as NASA's senior scientist for orbital debris research, tells Michele Norris that an event of this nature is highly unusual — and odds are slim that the debris will injure people or destroy property.
