Explanation: What happens if you crash a spaceship into an asteroid? In the case of NASA's DART spaceship and the small asteroid Dimorphos, as happened last week, you get quite a plume. The goal of the planned impact was planetary protection -- to show that the path of an asteroid can be slightly altered, so that, if done right, a big space rock will miss the Earth. The high brightness of the plume, though, was unexpected by many, and what it means remains a topic of research. One possibility is that 170-meter wide Dimorphos is primarily a rubble pile asteroid and the collision dispersed some of the rubble in the pile. The featured time-lapse video covers about 20 minutes and was taken from the Les Makes Observatory on France's Reunion Island, off the southeast coast of southern Africa. One of many Earth-based observatories following the impact, the initial dot is primarily Dimorphos's larger companion: asteroid Didymos. Most recently, images show that the Didymos - Dimorphos system has developed comet-like tails.

Did the impact change the trajectory of the asteroid at all? I know that was the purpose of the launch. Pretty cool, in any event.

Probably too soon to measure movement of the mini-moon very accurately.

If we would have hit it with a Russian Belgorad sub (really a modified oscar II), “betcha” the enemy asteroid would have moved...

Should have told Putin the asteroid was trying to join NATO - πŸ‡ΊπŸ‡ΈπŸ˜ŽπŸ‘

I don’t know if they have determined the effects yet.
