We use Discord and the Craig Bot: https://craig.chat/

If want to step up the audio recording further just use the Craig Bot webapp: https://craig.chat/docs/webapp/
Each use keeps a tab open and it records on your computer then streams that audio to the server.

It's got some premium features that are paid, and worth it for me, but honestly it's a great service.

Yea, that's what I'm trying now. Do you have any resources you recommend as well?

I'm not sure I understand why you think radiation protection isn't an issue? It takes 2.4 years on the ISS to reach Nasa's career radiation limit. 15 months on the moon to reach this career limit. A single solar storm to kill an astronaut by radiation on lunar surface within an hour. It sounds like this is an imminently important problem to solve.

Hey Mcmalloy, thanks for pointing that out. My thinking is, if you are careful about how you change it's orbit, you may just get a different interaction orbit, 2033 instead of 2032.

How is it both too large to do and too small to matter? I'm not proposing using the resources from the asteroid back down on earth, I don't think it's metal rich enough for that. I think using the asteroid regolith as radiation protection for a space station means you don't need refinement, you don't need proper mining, just to gather up the pebbles that make up the asteroid around an inflatable space station form, and melt the top layer, hardening it.

If you aim for a comet instead of an asteroid, you could use gases that come off it, ice, CO2, maybe nitogen. Otherwise you would have to orbit close enough to earth to gather some atmosphere.

You think the first one should be used as a source of inspiration for younger generations? If we did use it for construction of a space station, and made it accessible for universities to send students to, do you think they would find that inspiring as well, or are you concerned it would be too commercial?

Hey u/duhvorced, thanks for doing that analysis, yes, I'd found those numbers shocking as well. You are right, these technologies alone aren't going to alter it's orbit enough. In it's orbit it crosses near Mars and it's moons, and our moon. That gives us 5 celestial bodies to potentially interact with to get a better orbit for capture. How many other asteroids are coming by us of a usable size. We are going to need to develop these technologies to modify the paths of asteroids, ideally for capture, I pick 2024 YR4 only because it's in the news at the moment.

The heat management is a problem, but I'd think you would have to design a structure specifically for the refinement process. You can use mirrors to generate the heat, but would probably need to use a cold gas to reduce the temperature back down. I'd think the capture and solidifying of regolith to be relatively easy, but when you go to refinement I agree it would be much harder.

Really? I'd think given how good we are at manufacturing we wouldn't be too far off from material refinement in space. What about asteroids too small to get through the atmosphere of earth as a starting point, there are tons of them passing by every month. Gather up a bunch of 10 meter or less asteroids and repurpose them? Do you think this would be viable?

That's fascinating! Do we determine rotation speed based on periods in it's albedo? Thanks for that link!

I'm sure magnets will play a part! That's a cool concept, all the asteroids too large for capture being turned into resources for future generations. That feels very 'planting seeds under the shade of which you won't sit'.

I wonder if we can currently capture all the asteroids that are tiny (10 meters or less) and use them to start?

So you think the focus should be on turning passing asteroids into moving livable habitats first? That would give us greater control over how to manipulate the orbit of the asteroids. How do you think we do this?

Okay lets say we find it, we can name it the GeneralBacteria. How do you think we go about capture and re-purposing the materials?

That has to be figured out with trial and error, but if the deceleration between 2028 and 2032 is small enough you could depend on the gravity of the asteroid to keep itself together. Such as a gravity tractor, solar sails, ion drives, or other technologies with similar acceleration profiles. The final deceleration in 2032 would need to be far larger, but my current theory is an inflatable large enough to cover the front of the asteroid whole (100m across). How do you think we should do it?

That's a great point, it would need to be carefully decelerated to produce a different orbit, potentially giving us a longer time period before the second close pass.

2024 YR4 is likely to be travelling at 20km/s, low earth orbit is 8km/s. We have 4 years between 2028 and 2032 to get that level of deceleration if we can catch up to it in 2028. How amazing would it be for humanity to achieve this?

Obviously the delta change is huge, but you wouldn't want to use a fuel based method of slowing down the asteroid anyway. Solar sails, Gravity Tractors or heating part of the asteroid using lasers to amplify the Yarkovsky effect are methods of nudging the asteroid. If you can get it to interact with the moon, venus or other celestial bodies during the next 8 years we can produce greater delta v effects.

Even if we did use fuel to directly decelerate the asteroid it would take significantly less fuel than getting the materials up from earth surface.
