New NASA Mission To Help Us Better Estimate Asteroid Impact Hazard
Washington DC (SPX) Feb 08, 2013
Every year, sensors designed to detect nuclear explosions see harmless bursts in Earth's upper atmosphere from the breakup of an asteroid a few yards across. Tiny asteroids are much more numerous than big ones, so destructive hits to Earth are very rare. However, because of their potential for devastation, NASA's Near-Earth Object (NEO) observations program supports surveys which are undertaking sustained searches to find the largest objects and predict their impact threat to Earth. Accordin ... read more
