Technology?

 I just wondered what is actually going on...
  Tomorrow a " small rock" well 430 Ft is going to pass earth.  This is classed as a near miss with the distance being around 3.8 million miles  This "rock" if it hit would be 1.5 times bigger than anything detonated so far, 77 megatons.
  If this is supposed to miss? then why did NASA send up a rocket to land on it and explode to deflect it away from us?

I did already know it was just amusing how they sent the rocket off and kept it low profile.
  It was on my newsreel feed.

I think its to see if we have any sort of defence against asteroids if one was ever going to come in contact with earth. I think its a good thing to try and see if we can deflect rocks that could hit us, saying that though it does make me think what if they get it wrong and instead of deflecting a rock to not hit us, diverts its path so it does hit us.

asteroids and space rocks are scary as we can't see them all and haven't mapped them all so potenially one could be heading for us right now and we wouldn't know until it was close enough, some arn't even seen till its too late and hits us like the Chelyabinsk meteor that hit in russia a few years ago or the tunguska event.

I do believe we will need some sort of defence against them otherwise one day we will be sitting ducks, but hopefully one doesn't hit till far in the future and whereby we have set up a good defence system against them.

If anything was to happen atleast we know to send bruce willis up with a nuke to blow it up.

And so it begins.....
  For those of you that are up at 07:44 am in the Antarctic, there is an eclipse.
  It is happening right now so if you want a live feed try googling Eclipse today, or go to U-Tube later as I am sure it will end up there.
