Consider the Earth’s history as the old measure of the English yard,
the distance from the King’s nose to the tip of his outstretched hand.
One stroke of a nail file on his middle finger
erases human history.

It's mind boggling to think about the calculations needed to hit such a small target after traveling so far over such a long period of time.

It will be interesting to find out what comes back to Earth at the end of the mission.

I changed my mind yesterday. The new one doesn't work any better than the old one.

Ahh . . . Hyabusa was an easy one.

I think the Cassini and Voyager slingshots gave Excel a better workout. : )

True. And done with a LOT less computing power! (Did Excel even exist back then?)
But...
Voyager and Cassini didn't need to come back. (salute)

Amazing!

The explosive device, called the Small Carry-on Impactor (SCI), was released from Hayabusa-2 on Friday. The SCI, a 14kg conical container, was packed with plastic explosive intended to punch a 10m-wide hole in the asteroid.
