8C9416142-120312-neo-asteroid-threat-hmed-426pAs the anniversary of last year’s surprise Russian meteor explosion nears, a United Nations action team is taking steps to thwart dangerous space rocks, including setting up a warning network and a planning advisory group that would coordinate a counterpunch to cosmic threats. A global group of experts on near-Earth objects (NEOs) met in Vienna Feb. 10 to11 for the 51st session of the United Nations’ Scientific and Technical Subcommittee of the Committee on the Peaceful Uses of Space. The meeting came just a few days before the one-year anniversary of the Russian meteor impact. On Feb. 15, 2013, a 65-foot-wide (19 meters) space rock detonated without warning over the city of Chelyabinsk, injuring more than 1,200 people and bringing home the reality of the asteroid threat to much of the world. The plans the experts discussed have taken shape over a decade of work by the UN Action Team on Near Earth Objects, known as Action Team 14. AT-14 was established in 2001 and has crafted a roster of recommendations for an international response to the asteroid impact threat. Yahoo News
