NASA says there are 20,000 asteroids and comets in our solar system that are potential threats -- larger than 460 feet in diameter. So far, they've only located 6,000 of these objects.
Oh damn, more 'rocks of mass destruction.'
NASA is charged with spotting most of the asteroids that pose a threat to Earth but doesn't have the money to complete the job, a federal report says.
Specifically, the mission calls for NASA, by the year 2020, to locate 90 percent of the potentially deadly rocks hurtling through space. The agency says it's been able to complete about one-third of its assignment with the current telescope system.
NASA estimates that there are about 20,000 asteroids and comets in our solar system that are potential threats. They are larger than 460 feet in diameter — slightly smaller than the Superdome in New Orleans. So far, scientists know where about 6,000 of these objects are.
NASA calculated that to spot the asteroids as required by law would mean spending about $800 million between now and 2020, either with a new ground-based telescope or a space observation system, Johnson said. If NASA got only $300 million it could find most asteroids bigger than 1,000 feet across, he said.
