Space Station Trash Plunging to Earth

Oct. 31) - A piece of space station trash the size of a refrigerator is poised to plunge through the Earth's atmosphere late Sunday, more than a year after an astronaut tossed it overboard.

NASA and the U.S. Space Surveillance Network are tracking the object - a 1,400-pound tank of toxic ammonia coolant thrown from the International Space Station - to make sure it does not endanger people on Earth. Exactly where the tank will inevitably fall is currently unknown, though it is expected to re-enter Earth's atmosphere Sunday afternoon or later that evening, NASA officials said.
