While some space officials are worrying about the fate of the Martian rovers as a giant dust storm continues to rage on the Red Planet, others are having a bit of fun. An astronaut spacewalking outside the International Space Station tossed a 200-pound camera mounting out into the void. Mission Control reportedly called it "a fantastic throw." The next toss will be a 1,400-pound ammonia tank that made its way up to the station in 2001. Meant to serve as a backup coolant in case of a leak, the ammonia never proved necessary, so the astronauts are jettisoning it soon. Both hunks of space junk will orbit Earth for a while before re-entering. The camera mount should disintegrate completely, but scraps of the much larger ammonia tank may make it through—and, according to researchers, will probably land in the ocean.
