"A lot of empty space" doesn't really cover it. As the other comment says, on average there are about 600,000 miles (~1 million km) between asteroids. To put that into context, if you were in the the asteroid belt, and traveled around it for a distance equal to the distance between the earth and the sun, you'd only pass about 150 asteroids. And most of them would be only like 100 meters across. If you flew on spaceship through the asteroid belt at random, the odds are pretty heavily against you even being able to see a single asteroid in the distance, much less needing to worry about crashing into one.

Anybody anywhere doing work on this using current technology?

You don't want to shatter the asteroid. You do want to detonate it at a short distance, so that the side facing the nuke vaporises and pushes the asteroid away like a rocket engine. This has been simulated to work using supercomputers, how it'll work in practice is anyone's guess.

@faithnfire4769

2 жыл бұрын

If I recall the last bit of research I saw on the matter. It's an option, but the main issue is that it is still impressively difficult to really damage large hunks of rocky material. Even loosely held together, the bomb needed would be quite large (remember this isn't a demolition charge carefully placed, but something impacting at best and any distance greatly reduces felt energy). So really the question is, A. if you already are in this zone would a huge kinetic impactor be more effective. (because at sufficient speeds the impulse transfered could be huge) B. Would it even be possible to get the international or even national consensus to build such a nuclear tool. (as this is far worse than any nuclear reactor or propulsion) C. how effective a nuclear explosion in space is at actually transferring energy to an object. Certainly it is possibly the best excuse to use a nuclear bomb for civilian use I've ever heard. So hopefully someone is still researching it l, even if it's just for the next generations Scott.

@charleslambert3368

i don't think it's a lot less dangerous. An any case, you only have to give an asteroid a tiny nudge to move it 1 earth diameter (enough for it to miss us) over the course of many months. it's take a lot more energy than that to blow an asteroid apart, even if it's a pile of gravel held together by gravity alone.

We want to move it and not create tons of smaller chunks. One large explosion would be great for a decent boost but is more likely to shatter the rock and lose a ton of energy. Smaller more contained explosions or more directed thrust is needed. Rocket engine vs bomblette engine. Which is more usable) This test is a directed impact that will give us tons of data so we can do some simulations and thought experiments on how best to actually redirect a rock when needed.

Why do ion drives always seem to use xenon? It's expensive, it's hard to store (high pressure tanks are needed) and it takes a lot of work to get much of an exit velocity (high molar mass and it doesn't really like to be ionized). I'd think something like bromine would be a lot better. It's cheap (Nile Red made some in his parent's garage) easy to store (you could use a pop can with stable surface treatment) and it should be easy to accelerate (i.e. I think it's charge per mass when ionized using a given voltage is higher so the mass specific energy out the back should be higher as well).

Then, the kinetic energy of an exhaust atom is qV = (1/2)mv^2. With some rearranging that means the momentum per atom is p=√(2mqV).

Thank You Scott. I share your interest, and have been interested in anything about space since Friendship 7 when I was a kid. I'd love to see them land an engine that could put out a significant amount of thrust to see what we can do to an asteroid's path in space. A tiny change in trajectory over significant time and distance could theoretically avoid a collision, but that needs us to see it in enough time. I love your smile and obvious fascination. Life is just not boring when there's always so much to learn. If there's a day when I don't learn, I will know I'm dead. LOL

The insight gained from a mission like this could very well save the planet from hazardous Asteroids in the future. Can't wait to see how this mission goes.

I don't know why there is such a big hubbub over this SpaceX mission. After all both the US and Russian space programs have been hitting their marks for decades. Even India and Israel has some experience in this arena. (To soon?)

When it comes to LEO sure, but the records of things beyond LEO changes a bit. There are some gaps in your understanding.

The only involvement of SpaceX in this is providing the ride and having their meme lord giggle like a twelve year old at the "69"-bid. Yet this kind of bullshit brings more clicks and likes from the teenagers and devout followers of the technoking manchild than the actual content. The only thing I hate more than the YT algorithm that encourages this kind of bollocks is falling for it - from the stupid AF thumbnail I genuinely thought that SpaceX actually built a probe of sorts...

Prediction: most of the energy will not turn into asteroid's kinetic energy. Instead it will be dissipated into heat and the kinetic energy of the debris that will just escape the twin system. Since change in mass or temperature will not result in the change of the orbital period, we will probably see very little of the desired effect.

Don't look at the energy here, look at the momentum. That's a better indicator of the asteroid's trajectory change.

likely, yes. though... that heat will re-radiate (probably unevenly, cuz lumpy space rock) and THAT can nudge it around

Great job, thanks 👍 Don't forget the nearby Uncle Asteroid - Biggus Dyckus 😁😂🤣

This mission is so cool, plus my dad worked on the DART's star tracker!
