Dart impact as seen from Earth

Hope this is ok to post here. Just seen this on the news and was blown away, incredible footage.

Really impressive, thanks for posting. Tried to get a live earthbound telescope feed from South Africa last night, but yes, you’ve guessed it, they were clouded out.

That is ompressive and thanks for the posting 👍

Google  "dart mission" and see what happens to your screen 😉

Really stunning. I also love the fact that not only did NASA attempt to impact the moonlet, they also decided to make things harder by having a little separate "drone" detach and film the impactor from the side/at an angle, as it hit.

Really, so amazing what mankind can achieve.

My question is how that impact may or may not have affected it's speed or trajectory, I would assume it has but by how much.

Dr Becky is pretty good on that question 😀

Great video, thanks. 
 

Regarding a much larger body would it not make sense to detonate a massive nuclear warhead at some distance so as to change the objects trajectory without creating many smaller threats? or am I watching to many sci-fi flicks 😄

worry there would be a failed launch i guess

I am no physicist, but I suspect it all depends on what is the most efficient means of transferring energy from the method used to deflect the asteroid to the asteroid itself.  I suspect, but don't know for certain, that with a small body impacting the asteroid you get a very efficient energy transfer which can be targeted at the point of impact most likely to result in that transfer of energy altering the orbit in the required manner.  I think it would be more difficult to achieve these twin goals with a nuclear warhead detonated at a distance.   Then again, it is now some 36 years since I failed my physics GCSE. 😂

Wow!  Thanks for posting 👍👍
