Tank of toxic ammonia coolant thrown from station more than a year ago
NASA astronaut Clayton Anderson, an Expedition 15 flight engineer, tosses a hefty unneeded ammonia tank the size of a refrigerator ovebboard from the space station during a July 23, 2007 spacewalk. The tank is expected to reenter Earth’s atmosphere on Nov. 2, 2008.
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 (635-kilogram) 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.
