I thought it was really cool.Well, I thought the picture was coming from a telescope and we’d see an explosion or sumpin’. Nope. It was some kind of camera on the spacecraft itself…the thing that smashed into the asteroid. So of course we get no image of an impact because it blew up. But we saw up to the moment of impact and it was a direct hit. Kinda neat. Now NASA will analyze what effect we had in moving that asteroid. Not sure how long that will take.
There are several telescopes around the world trained on the asteroid. NASA/APL knows from 7+ years of watching that it takes ~11 hours for the smaller asteroid to complete 1 orbit around the larger one. They will know, and announce, by the end of the week what the time of the new orbit is.
FWIW, DART was roughly the size of a full size school bus hitting an object that is 2 times the length of the statue of Liberty.
Now the science begins. They'll be collecting data for several years via ground telescopes, Hubble and Webb. Coming next is ESA's launch of a spacecraft that will study exactly what impact (no pun intended) DART had on the asteroid. That will take another couple years and then one or two more to collect all the data.
I watched it on NASA tv, and man, those folks were seriously geeking out!!!
Thinking they missed a great opportunity by not having Billy Bob Thornton there for commentary. Ya know, the movie...
On a serious note though, anything they can do for planetary defense is a win in my book. Also this marks the first time humanity has ever moved a celestial body.
Yeah ok, I'm geekin' out.
