Space junk falls harmlessly in Pacific

CAPE CANAVERAL, Fla. -- A refrigerator-sized piece of space junk fell harmlessly into the South Pacific Sunday night, according to NASA.

The junk was a tank full of ammonia coolant on the international space station that was no longer needed. Astronaut Clayton Anderson discarded during a spacewalk in July 2007.

Space station program manager Mike Suffredini said Monday that the debris splashed down somewhere between Australia and New Zealand Sunday night.

The tank had served as a reserve supply of spare coolant at the space station since 2001.
