That we need to prepare and have the technology to do so, but have no international consortium that will bring us all together is the sad part.

So we can hit an asteriod in space but we dont have running water and proper healthcare here at home? ...wow

[aaronthenorm]

So now in a tragic irony the path that was safe it will now come back and SLAM into us! Very Simpson like!

Amazing outer space video footage of an asteroid .

Emptiness of the mind
encompasses pure emptiness,
tranquil emptiness and the empty space.
When the mind encompasses all of space,
we can hold anything in our hearts.

What sound like a blessing right now can b used as a weapon in the future

[WindFireAllThatKindOfThing]

Someone just got the high score on Asteroids

[bzboi]

wont this cause a domino effect? we just nudge something that wasnt suppose to move out of its orbit. now that its off course wont it hit other asteroids off course make things worse?

[yolobrosuff]

I SEE THE ROCKET HIT IT'S TARGET, BUT DIDN'T MOVE IT OFF COURSE . LOOKING AT THERE ACTIONS SPEAK FOR ITSELF ...GOT MORE EXCITED WHEN IT HIT, THEN WHEN THEY LOOK TO SEE IF IT MOVED OFF COURSE ...

[TheFrancessmith]

We all as well should prepare in all other aspects !!!

[BillStreets_]

how many ppl these days dream about being struck by a comet 🌎☄️?

[Reconseal]

That was most likely a softer asteroid with light ice and minerals instead of something more with heavy metals. But none the less great work NASA!!! 🌎

[shamelwilkens]

They forgot to mention what the asteroid is made of also plays the big roll in defection.

[MrJeepCanada]

I came out with an article that said there's an Asteroid heading to earth right now but will miss us. I know they are tracking them but for them to do this must be one that will impact us. Not saying a world ender but one that can destroy a hole city.

[SAMPINJ]

Sad sad we need to educate the masses and concentrate on something other than racism war and greed so we can focus on what matters

[Bocphu]

We can now blow up Planet X when it starts to arrive.

[MhmHm_]

Preparing for things that may never happen waste of money and time

[walkerfamilyoverlandingpho]

They practicing people.... and they know why..

These people watch too many super hero movies! The same people hysterical over the earth's cyclical climate change think its awesome that we are shooting a spacecraft at a non threatening asteroid with no thought of the possibility of unexpected consequences.
