NASA has been building a system that can defend the Earth against dangerous asteroids, and it is nearly ready to go into space!
I will sleep easier when that happens. Hey, I don't lose sleep worrying about a catastrophic asteroid impact, but it could actually happen. And if it did happen, boy would we feel stupid if we had the technological capability to defend against it, and yet didn't make the capability operational.
Well, it appears that we might have that capability. Still must be tested, but at least they're trying.
The experiment that could save the Earth: Nasa's spacecraft made to deflect incoming asteroids has entered the final stages and will launch 'by 2020'
Here's the more technical description of how it will work.
Double Asteroid Redirection Test (DART) Mission
And a schematic:
So, don't you feel more relaxed about this now, too?
