Can We Stop Asteroid Bennu?

With the recent return of NASA's OSIRIS-REx from Asteroid Bennu - Earth's close encounters with asteroids have been on many peoples' minds equally fascinating and alarming us. But what if we could prevent a potential catastrophe? Let's dive in an explore the groundbreaking methods NASA is researching and implementing to divert these celestial threats.

Remember to stay away from windows. In Halifax there was a Halifax explosion that leveled the entire city. An anchor off of a ship flew several km and landed in a park in the middle of town. Most of the injuries where people staring out of the window looking at the boat that was about to explode.

1 in 2700 sounds terrifying. Needs more 0s.

I love how Osiris just shot a package at us then went on its way to another mission. It's amazing how just over a hundred years ago, we were just beginning to fly via the first prototype aircrafts.

Aside from the bad thumbnail this was a well executed and informative video without the typical dumbed down sensationalism and background music. Subscribed

The 'mushroom cloud' graph' was much much better than any pie chart or saying thousands of Hiroshima' s.
Being able to still 'see' the starting point has a great effect

[kelly]

wow this Osiris mission is certainly getting some work done, well done to the team behind it!

[peterjames]

Superb mini documentary on this important subject. Well done!. It is reassuring to know that serious work is being done to try and mitigate such disasters.

[thomasboomer]

Dr. Miles, you have a gift for explaining complicated subject matter. Thank you.

[eliteiel]

This is the type of content that should earn a sub… not that bs influencers that are dominating youtube rn

[ttystikkrocks]

Excellent treatment of the material. I've been following this topic for half a century, since I was a child, and it's exciting to see the developments in knowledge, detection and potential options for dealing with this threat.

Thanks for resisting the temptations of shallow content and clickbaity titles! I'm subbed and I'll be looking forward to more videos like this one.

[bo-bodad]

Well done! It's nice to watch a reasoned discussion of a potential asteroid impact rather than the sensationalist click-bait you typically see.

[PrometheusZandski]

Incredible content. I doff my hat to you, sir. I was afraid this was clickbait, but I was delighted to see the detail, realism and well researched content you presented. If only others on YT would be half as good as you.

[vanpunk]

Great video, really like the informative pacing, kept me engaged the entire video.

66 million years ago. Seems like just yesterday it was 65 million years ago. Gee time flies!

I wonder what our technology will be like in 30-40 years from now. Which is pretty much the time I have left. Unless I somehow make it into my mid 80s. Which I doubt, unless I make changes to my lifestyle.
I hope there's a technological leap during that time. Probably not as great but similar to the kind my parents have experienced. They were born in the 1950s.

i truly enjoyed this clip - its just really scary when you realize that earth is a not-so-large target in a shooting gallery where the trajectories of objects are dictated in both circular and straight-line principles. Its reasonable that nothing could be More than 100% spot on but dude, if i ever could... 11/10 for this discussion 🙂

[thomas]

OSIRIS ftw. Fascinating topic and great content. Thank you Dr. Miles.

[honza]

Well presented and informative vid. Great job 👍

[bugscorb]

Very informative. Thank you for making the video.

The bit about the energy @1:15 isn't quite right, that wasn't the impact energy, that was the kinetic energy before it entered the atmosphere, it lost a lot of energy as it was passing through the atmosphere, most of the energy it had was absorbed by the atmosphere and resulted in the air burst, the actual ground impact was much less than 500KT.
