NASA slams spacecraft into asteroid. If this technology was available a gazillion years ago we wouldn't be dependent on oil today.

I watched the recap of the hit yesterday. I am continually floored by the level of accuracy these missions show is possible. Launching a 24,000 mph vending machine at a rock in space and hitting your target is a phenomenal feat. I look forward to the results to see if and how much that rock got moved.

And, if we had this tech a gazillion years ago, it's likely we wouldn't be here either.

I have this feeling that I can't shake that we've moved it such that it will now be on a collision course with earth.

Don't worry. That will be possible someday too.

An interesting take.

Wherever it going, it's very possible that it will run into something, someday

Maybe 65 million years ago [give or take a million] someone someplace steered an asteroid away from their planet, and it ended up crashing into ours? Could we have just done the same to someone else?

An interesting take.

Not only from a mass extinction POV, but also that the current thinking is that all of the water on Earth came from icy comets & asteroids; shove them out of the way and Earth is waterless [unless, maybe you can create H2O from hydrogen + oxygen + lightning? I'm not sure about that one]

It's amazing what our brains can remember. I wouldn't have seen that game for an incredibly long period of time, but those game sounds (in particular the UFO) and it was like 'yes'.

I guess the "Don't Look Up" movie storyline just became obsolete as well.

Yeah, I don't know why these guys are all excited. I've been doing this for 50 years.

I'm beginning to think that we are much more fucked than I thought.

It's highly unlikely that changing an asteroids path by 1-2% will cause it to be flung out of our solar system, through interstellar space, into another solar system, and collide with an inner planet. It would more likely continue to orbit the sun, just on a slightly different path. Our Voyager missions showed that leaving the solar system is possible but takes a lot of planning and angles/ velocities to exit the solar sphere.

And if they actually did that, humans should be sending them flowers or a shiny golden CD. The destruction of the climate and removal of the large lizard/ bird thingies with big teeths paved the way for small, warm-blooded rats to take over the planet.

Yeah, it's highly unlikely that a bunch of clever monkeys using sophisticated tools could do anything like that on purpose, but we're just stupid enough to do it by accident/dumb luck

I think they prefer the term "Republican."

Actually no. In the movie they plan a mission like that, but then abort it because they think they can make a profit from mining the asteroid instead (which goes wrong). That's kind of the point of the movie.

It was an allegory. SDG knows this. The somewhat mixed critical reception of the movie and lack of understanding of the layered meanings is a higher level abstraction of the same allegory IMO. Very meta, the responses to the movie could have been in the actual movie itself, which was also the point.

Don’t Look Up is playing out in real time right now… replace “asteroid” with “fascism” and “mining” with “cashing in” and you’ve got a good movie. Throw in the “are we the baddies?” meme and the “I’m not a Nazi or fascist, I’m just conservative” meme and you’ve got an Oscar winner. Bonus for a Cassandra reference.

At any rate, JPL gets shit done once again. Culture of winning. Mission Control and their culture manage to keep mucking up the Artemis mission.
