But I think we should say what DART is.

So DART was a NASA mission, the Double Asteroid Redirect Test.

It was a test on an actual asteroid to see if we can deflect it so that in the unlikely case that an asteroid comes towards Earth for us to be ready.

And it was a complete success.

So we can all feel safe.

We can, so far, yes.

So the impact was very successful.

And how on earth did you go about doing this?
