NASA Hit an Asteroid 26 Times Further Than Expected | DART Dimorphos Impact

[@Stewi1014]

The way that ESA(+friends) and NASA(+friends) work together on specific missions, but also (as in this case) develop missions in tandem that compliment each-other is truly an example of humanity at its best. Space should be an excuse for international cooperation; never national, much less corporate, posturing.

I would call it an existential imperative, rather than just "worthwhile". Sure, percentages are low for an actual life ending threat, but certainly not zero. Being able to do something to this effect may someday prove to be the only reason we survive. As an aside, as someone who played percentile based rpg's for years, I never ceased to be amazed at how often you would roll that 1.

[@-BuddyGuy]

​@@redrocklead​ An automated system that could last longer than a century would be enormously difficult to design. All the components would need to be chemically stable over long periods. It would need nuclear fuel with a long half life, very robust protection against cosmic rays, and highly exotic integrated circuits that don't break down with extremely long term use. The semiconductors for this would require new factories. The mapping of future threats would also need to be happening, to automate this would be an even bigger challenge than designing the projectile's vehicle. Earth's atmosphere just isn't practical for zero maintenance long lasting machines, so we would need multiple satellite telescopes with all those same design constraints. The orbital decay would have to be managed somehow as well. Getting past prototype testing would take decades or even a hundred years of changing governments without any of them canning the project. And then we might get a few hundred years of functionality out of it with possibly one of the most expensive engineering projects of all time. Since we can see many of the threats 100 years out anyway, and the probability of an existential threat coming in a random 100 year window after we build this is so very low, the return on investment for this project would likely be zero, and best case a few hundred years. So while the sentiment is nice I don't think it would ever be feasible without a total revolution in autonomous maintenance, construction and space flight. The technology levels required would make space X landings look like caveman technology.

People have made much talk of the reality vs expected results of the DART mission, and forgetting to mention that their ‘expectation’ was not the published figure, rather this was a ‘minimum’ result. They are space nerds, they’re not going to be that far out. However, there was a legitimate difference which was not originally accounted for. That’s why the experiment was done - so that we could figure out how to divert a dangerous asteroid if ever it was required…

[@takumi2023]

I always wanted to know the differences. What were the expected figures and why was the figure different from the observed effects. I dont think i found a video explaining this sufficiently. I understand basic physics, so the minimum should be based on the lowest speed and density of the astroid at impact. But beyond that, im kinda stumped.

Dart has taught us that tracking and cataloging is more important than deflection. Deflection appears to be easy, if we have sufficient warning time. That caveat, 'IF' looms large.

[@Lukeasdf123]

seems to be that way based off of this test but just to be sure I'd say we need to do it a few more times on various types and sizes of asteroids things look good!

[@kukuc96]

And there is that adage "If brute force isn't working, you are not using enough of it". If we have a shorter time, and a big object, we could just send more and bigger impactors. Sure it's expensive to dedicate every rocket you can build to it, but it is cheaper than extinction.

The Ordo Acronymis is a shadowy yet essential division of the Adeptus Administratum, tasked with crafting the sacred abbreviations that guide every facet of the Imperium's countless operations. Their skill in distilling convoluted mission names into memorable acronyms is revered as both an art and a divine science, ensuring morale, clarity, and compliance in the field. Each acronym undergoes a rigorous vetting process involving phonetic resonance, historical allusions, and subtle prayers to the Emperor, with fees for their services often rivaling the cost of an entire campaign's initial deployment. To fail in this sacred duty is unthinkable; after all, even the mightiest crusade would falter without a properly blessed and memorable moniker.

It is decieving because it's not to scale. In reality each of those dots should be an infinitesimally small part of a pixel. Asteroid "fields" are not like sci-fi, they are incredibly far apart, even in the densest areas of the solar system. If you flew through the asteroid belt between Mars and Jupiter with your eyes closed, your chances of hitting something are less than winning the lottery.

[@rxmclaren7]

The thing that is super scary to me is that such a small satellite moving at 22k km/h hit an object with such force that it moved Dimorphos in the first place...physics is awesome...the scary part is if such a small object can do that much damage, what would happen if an object with a proportional size of these two hit earth...

[@lancerevell5979]

I wonder if the miniasteroid's orbital time change and shape change would be markedly different had it been made of solid rock, rather than the mass of smaller rocks and dirt? 🤔

[@brentogara]

Good point! Would the momentum transfer be any different if it were a solid mass? Would the transfer of energy remain the same overall, or be meaningfully different? We should ask an astrophysicist!

[@kukuc96]

It definitely would, but no asteroid is a solid rock, especially not big ones you would worry about deflecting. That's just a sci-fi thing. In reality the way they form doesn't create big solid rocks, they are all loose piles of rubble.

[@Mark_Bridges]

A lot of the orbital change was caused by material ejected from the asteroid. That material acted a bit like a rocket exhaust pushing the asteroid away. A solid rock or metal asteroid should have a different reaction, although I have no idea how much difference to expect.

Nuking an asteroid can work very well if instead of trying to blow up the asteroid, you place the nuke next to the asteroid then detonate it. When this happens, the surface of the asteroid facing the nuke is vaporized, shooting off the rock at very high speed, essentially turning the whole asteroid into a rocket. Repeat this process as many times as necessary

[@ThetaGraphics]

Kind of ironic that the option dismissed in “Armageddon” (nuking the asteroid’s surface) was actually the correct one! 😆 (as long as it was hit from the side)

Obviously we want to nudge an asteroid away from hitting the planet completely. But if you could fragment an asteroid into 20 smaller pieces and even if all 20 smaller pieces hit the Earth, it won't go as deep and it won't do as much damage. So it won't kick up as mantle into the sky and have it raining down all around Earth.

13:12 I don’t believe focusing played a big role at all. As you said earlier, the closest complete image was recorded at a distance of 12 kilometers. Relative to the scale of the focal length of the telescope, this is probably still close enough to consider ‘infinity’. The very last partial image, is however clearly blurry and that may indeed be caused by the telescope finally getting close enough to be out of focus.
