Killer Asteroid: Defending Earth 4k

When natural disasters threaten, we turn to science and technology to warn us… to seek shelter or get out of the way. But can they face the ultimate threat: speeding projectiles from the depths of space? Cutting-edge space missions are underway to deflect and destroy space objects that threaten to rock our world. Can they save the planet from a killer asteroid?

Bravo once again SpaceRip aka Thomas Lucus EXCELLENT WORK

4:27 That was one of the best shot's I've ever seen. Just the small size of the rock and the huge size of the fire around it is insane.

As Neil DeGrasse Tyson says, "Asteroids are the universe's way of asking us HEY, HOW'S THAT SPACE PROGRAM GOING?"

We could get the UN to write a strong letter of condemnation and send it to the asteroid.

The golf cart moved the pyramid much more than was expected. It seems like good news for the earth defense folks.

[markcostello]

how will we respond? if its anything like covid then were all fucked

[orangecreme]

I know I don't like a lot about life on Earth, it doesn't mean I want a rogue rock to destroy everything.

The only downside of breaking a big rock into smaller rocks is that they will generate heat as the burn during entry into the atmosphere. Even if they don't hit the ground, their collective results can cause widespread fire outbreaks.

Beautifully explained. Hope these ideas and many more new ones keep us alive, save us from armageddon. Something should be done for the unpredictable killer volcanoes, earthquakes that are a constant threat to life on earth.

The DART mission was successful in nudging a small asteroid from its prior path. We have to get reeaaallly good at this thing so when the eventual big ones come inside our moon's trajectory we can nudge it away again! BTW if a big one hits the moon we are also DONE

[thomascopley]

Awesome video. Thank you for sharing it with us

[Doitgood]

I’ve always thought that the better option would be to have a starship gently nudge into the object without breaking it, 😮and then push it out of the way rather than breaking it up into smaller pieces

The greatest disaster we face is.. EACHOTHER

[mansoormannix]

Now we know we are not completely safe from external forces but some powerful being is protecting us for reason...

[CesarLopez-ndle]

Detecting these objects is key and finding and developing technologies to destroy monitoring thier trajectory is also key in determining whether it hits our planet or misses our planet 😊

[johnfic]

I still think a nudge is better than a massive explosion of rocks falling onto us is better.

Great doc however I was hoping to hear more comprehensive data on probable impactor origins and the orbital interactions that can move small bodies into the path of Earth, such as s7 secular resonance and asteroid families.

13:05 I've been there twice! On one visit, hiked the entire circumference.

[rebjorn]

Best option is to have all the Chinese jump up and down at the same time, disturbing the Earth's orbit

Killer asteroid. My boss your still expected to come into work. Would you like a day off with out pay? So your saying you are unavailable?
