Is Earth ready for an incoming asteroid? Not at all, says NASA scientist.

Not long ago, news of a massive asteroid hurtling toward Earth would be a death sentence that humans, like the dinosaurs before us, would simply have to accept. But as near-Earth object detection has gotten more sophisticated, a new field called Planetary Defense has risen to meet the challenge of defending Earth from asteroids.

However, speaking at the annual meeting of the American Geophysical Union, Joseph Nuth, a researcher with NASA’s Goddard Space Flight Center, warned that while asteroids and comets capable of resulting in mass extinctions are rare – as in, every-60-million-years rare – even small objects from space can cause a great deal of damage and the planet’s scientists are are still woefully unprepared to deal with the threat.

“It is really imperative that we reduce our reaction time,” Dr. Nuth said at the meeting. “The biggest problem, basically, is there’s not … a lot we can do about it at the moment.” READ MORE.
