Well, howdy there internet people, it's Bob again.

So today we are going to talk about how NASA has a spacecraft perfectly on course to smash into an asteroid. But that's the point. It's okay.

It's part of Dart, the double asteroid redirection test.

If this sounds vaguely familiar, it's because about nine months ago, I made a video talking about it,

it said it was going to take forever to get there. It's almost been forever.

So what's happening? The idea is to develop the first step in a planetary defense system.

So if there ever is a situation

in which an asteroid is coming towards Earth,

and Bruce Willis isn't available, they can use what is in essence a

space battering ram to alter the course of the asteroid so it doesn't hit Earth.

At the current time, there is no threat.

This is a proof of concept.

This is just to kind of test it out, see if this would work,

and see if they can move the asteroid.

This test will be taking place

about 6.8 million miles from Earth and it is designed to hit one

asteroid that is orbiting a second asteroid, the asteroid that is going to be impacted is about

520 feet long which is definitely big enough to cause a problem if it was to

hit Earth. The spacecraft, the battering ram is going to be moving at around

15,000 miles per hour. So, this is the first step. This is one of those things that you

definitely want to try out before you have to actually use it.

And while there has been no evidence whatsoever, no statement, anything like that suggesting that an asteroid is coming towards Earth at any
