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.

Tens of thousands of Australian households will have their rubbish and recycling monitored by tracking devices placed in their dustbins in a move dubbed by the media as “Bin Brother”.
Officials on Monday confirmed that 78,000 new council-issued bins in the eastern suburbs of Sydney have been fitted with small radio frequency tags, which allow for data collection.
Each bin will transmit a unique identification code to the rubbish truck which weighs and empties it each week, allowing officials to identify how much waste is produced at each address. Continue reading »
