Without more funding, NASA will not meet its goal of tracking 90 percent of all deadly asteroids by 2020, according to a report released today by the National Academy of Sciences.
The agency is on track to soon be able to spot 90 percent of the potentially dangerous objects that are at least a kilometer (.6 miles) wide, a goal previously mandated by Congress.
Asteroids of this size are estimated to strike Earth once every 500,000 years on average and could be capable of causing a global catastrophe if they hit Earth. In 2008, NAS's Near Earth Object Program spotted a total of 11,323 objects of all sizes.
