Space station trash plunging to Earth

Space station trash plunging to Earth: "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 expects up to 15 pieces of the tank to survive the searing hot temperatures of re-entry, ranging in size from about 1.4 ounces (40 grams) to nearly 40 pounds (17.5 kilograms).

If they reach all the way to land, the largest pieces could slam into the Earth's surface at about 100 mph (161 kilometers per hour). But a splashdown at sea is also possible, as the planet is two-thirds ocean.

"If anybody found a piece of anything on the ground Monday morning, I would hope they wouldn't get too close to it," Suffredini said.
