Firing the cannonball enabled researchers to directly observe the formation of a crater in microgravity for the first time, answering how much the microgravity affects crater formation.

The crater growth process appears to be controlled by the surface gravity, not by the surface material strength. In fact, the diameter of the new crater on Ryugu is about 7 TIMES LARGER than if it had formed on sand under the Earth’s gravity.

“If we want to deflect an asteroid by an impact, we need a much better understanding of this process,”

“All this is super exciting.”

Like ol' Ron Paul said, last year over a million people died of TB, and nobody said a word; and it appears some interesting drug developed for Ebola seems to cure Coronovirus, and time marches on, while down here in Costa Rica I saw an old lady buy twenty rolls of toilet paper and wondered what the world was coming to; these determined astro physicists keep plugging away at the only problem we really have, survival in a pinball machine on a ball covered with wonder, and us being the only conscious creatures on it, and not all of us at that, it would appear. Thought you might need a little distraction~ here you go!
