On Monday, Sept. 26 at 7:14 Eastern time NASA will crash a satellite into an asteroid. I think it will be streamed live.
Mission is called DART, they want to see if they can nudge the orbit. A step towards protecting Earth from future asteroid strikes.
They call it DART, my name for it is “The Bruce Willis Mission”.
