That was a lot more powerful than I expected.

The explosion was much brighter than the asteroid, and the ejecta was vey visible. It was a much bigger bang than the animations they published earlier.

I guess a couple of hundred pounds at 14k MPH adds up to a lot of kinetic energy.

      - That's about 600 kg. - ER - 9/30/2022 12:58:52 PM
        
        This reads like it's relative to Dimorphos - BuckGalaxy - 9/30/2022 3:48:33 PM
        
        At that speed, and with 600kg mass... - RL - 9/30/2022 5:36:16 PM

  - Probably an indication it was more rumble than solid rock or metal - BuckGalaxy - 9/28/2022 1:02:42 AM
