NASA :Asteroid Data Hunter

NASA Launches Asteroid Contest

NASA launched a set of "Asteroid Data Hunter" developer contests in a quest to enlist scientists and coders to help catalog small(ish) asteroids that could be hazardous to Earth.

NASA has a handle on 98 percent of near-Earth asteroids at least .6 miles in size, but it now wants to get its arms around smaller ones that still could pose a threat.

The asteroid believed to have wiped out the dinosaurs was at least six miles wide.
