Clearing Space Debris

[@FloraJoannaK]

I mean... Propulsion, robotics and life-extension are all charismatic subject matters in futurism, but what about the literal plumbing and trash collection? It's such a non-issue in the West, that few think of it-- but reading some accounts on 1800s in London and New York, one can only wonder what kinds of problems a space habitat of similar population might have. Interesting stuff!

My thought is- it isn't simply 'trash' being scattered up there; it is highly refined metals and ceramics many of which could still be useful, especially if they could be taken apart. Orbital recycling is the key here; not just letting things burn up but actively collecting them at the end of their life, towing them up to a higher orbit where those materials can be put to use. Maybe humans would have to be out there at first to get everything started but once machinery is in place they can depart and leave it to work-at-home drone operators. Think of all those beautifully machined, aerospace-quality aluminium structures; they wouldn't need much effort to repurpose.

[@robertkesselring]

Sweeper lasers could be duel purpose. Light has momentum, which means lasers have recoil. Lasing a piece of debris behind you also boosts your own orbit. If a satellite is high enough and has enough solar panels to maintain station keeping with the laser recoil, it could sit up there indefinitely clearing debris behind it as it goes.

[@Vhalikuporamee447]

That effect is absolutely miniscule. The sun's rays bouncing off your solar collectors might even be more substantial.

[@sarcasticpomegranate4549]

The main source of force for debiting with lasers is blasting of mater off the item to create a thruster to de orbit the object.

One more reason to push right to an orbital ring, not only would less junk be generated, but it would necessarily have a defense grid comprising mounting laser brooms on the ring would have millions of units with unlimited power for maintaining clear orbits

[@Tehom1]

This is an important issue. I'm always surprised not to see SPADE mentioned, since it is the most realistic and practical option. Basically a ring in the upper atmosphere lifted by balloons puffs air upwards into the path of space debris.

[@YodaWhat]

Exhaust from chemical rockets does much the same thing, but accidentally.

I take it the puffs of air are to act like the atmosphere to slow them down or to push them away to grave yard orbit.

[@YodaWhat]

@@mr.ackermann807- Only to slow them down. Any air puffed up from below will be practically motionless, compared to orbital velocity. Plus, being at right angles to the orbits, any upward push would only serve to increase orbital eccentricity.

[@FourthRoot]

I've thought a lot about Kessler syndrome, and I have gradually changed my mind to conclude that the hazard is overstated. When two satellites collide in low earth orbit, they effectively produce 2 clouds of debris. But only small cross sections of debris from those clouds actually remain if orbit. If the resulting velocity change vector imparted on an object ejected from a collision has a significant radial, antiradial, or retrograde component, then its periapsis will be low enough that it will rapidly decay. This consideration greatly increases the calculated "critical mass" necessary to initiate Kessler syndrome. Also, the assessment that Kessler syndrome would make LEO impassable for any significant length of time is incorrect. If there is a collision cascade, there is effectively no limit to how thoroughly the debris would pulverize itself. The result would be a ring of ultrafine dust, perhaps even approaching the atomic scale. The only debris that could possibly persist might be a thin ring of dust directly over the equator from about 1000 to 2000 miles in altitude. But that's nothing we couldn't avoid.

[@BillyOrBobbyOrSomething]

I’d need to do the math a bit (probably will later after studying) but at face value it seems highly unlikely that any two same-direction (W to E) satellites colliding would provide enough change in velocity to de-orbit any debris quickly enough to negate the risk of Kessler syndrome significantly. I mean yes a majority of the resulting debris would be sent into a decaying orbital pattern but quickly enough to avoid problems??? Idk. If you’re done the math I’d be happy to see your thought process here

[@FourthRoot]

@YeaaIJusShiddedOnEm When 2 satelites collide at these velocities, very little momentum is exchanged. But both satelites basically explode like water balloons. Most of the debris cloud expands approximately perpendicular to the relative velocity vector. In order for a satelite to remain in orbit below a certain altitude, its velocity vector must be nearly parallel to the earth's surface. Let's consider an east-west collision between two satelites at 500km. Virtually none of the debris will receive a prograde kick. Some debris will receive a retrograde kick. If that kick is more than a few hundred meters per second, that debris will reenter within half an orbit. For debris that shoots radially or anti-radially, the bump needs to be bigger, perhaps 1 km/s, but that's nothing compared to the velocity of the collision, which is 15 km/s. The only debris that would survive is debris that is ejected north or south with no significant radial or retrograde component. I would guess 75% of the mass would reenter within 90 minutes, and 90% would reenter within 24 hours.

[@pineberry212]

In my pathfinder homebrew, it takes place on a dyson ring swarm. The civilization makes use of megastructure sized nano swarm cubes of ballistic gel, clear so that sunlight can reach internally to solar cells. They use ion power to move around, and use the things they intercept to build further/fuel themselves. I realize that could very well be a big ol safety hazard to anything that runs into them, and a real risk of paperclip maximizing. Tiny pieces that get ejected simply rearrange to fly back to the blob, and burn up all of itself doing so, or have enough mass to start as its own cleaner.

[@pineberry212]

Or instead of clear, green tint to make use of plant reception to absorb sunlight. Yes they are a gelatinous cube technically.

[@benjaminhenderson5025]

Man its really funny this is your topic. I just had a very random conversation about removing space debris with my Mom on Christmas. 😄

[@UrdnotChuckles]

Wasn't there a charged electron beam being developed at the University of Colorado? Having something akin to a tractor beam might help plenty for space debris clearing. But yeah, as we start building larger ships in space it would make sense to armour them to deal with the tiny stuff. Then we can focus on the bigger and easier to track stuff.

[@YodaWhat]

Charged Particle beams would be nearly impossible to put on target, much less keep on target, because of interactions with Earth's magnetic field and the slightly-magnetized plasma of the exosphere and upper atmosphere. BUT it is relatively easy to make Neutral Particle beams, which are not immediately deflected, but do gradually become ionized when passing through a plasma, and thus deliver charge and a small push.

[@lamebubblesflysohigh]

I think laser is the most realistic and practical option. Technically we can build one right now, that technology already exists.

[@skateboardingjesus4006]

Lasers have a lot of potential. An abundance of unimpeded sunlight that can be used to nudge space-junk through ablation and that can also be used to alter the orbit of the laser platform itself, making it probably the most energy efficient option available.

[@johnsmith-vn9cs]

Cheapest least problematic option would probably be Bigass mirror(s) in high orbit, or even Lagrange point(s). Use them to reflect solar radiation in large areas of space to push everything down (or up). No ruinous energic costs, not limited by magnetism of the targets, no prohibitive calculation and targeting abilities required.

[@shanepye7078]

I’ve seen demonstrations where a ball bearing is dropped through a coil and nothing happens. It’s then activated and the ball dropped and it travels slowly through the EM coils. Would something like that be possible on a much larger scale to clean N.E.O?

[@atk05003]

That sounds like magnetic breaking due to eddy currents. I suspect that using that effect to clear debris would require huge magnetic fields. Laser brooms or probes that physically intercepting objects would probably end up being simpler for a similar effectiveness.

[@youngimperialistmkii]

Rifts! That brings me back. I used to play Hero's Unlimited, back in the day.

[@rainerandkatieniederoest825]

I suspect the question, "what is optimal orbit, that would eventually pass close to the largest amount of debris and defunct satellites?", is the best way to start solving the problem. Since rendezvous is costly, maybe the focusing on the necessary orbit first will suggest whether collection, ionization, atomization, or de-orbiting should be the first mission.

[@RicksPoker]

Science question: Why not use a charged particle beam weapon to put a few electrons on the small debris. The Earth's magnetic field would engage, and the objects would be kicked out of the current bad orbits into lower ones (and burn up faster) or higher ones where people care less. Eventually they will lose the charge, but it seems to me that this is a cheap way to move small debris out of the orbits you care about. Warm regards, Rick

One way you could get a lot of debris in orbit would be after a space war. Also if we did have too much FOD flying in orbit then one way that we could remove it is with aircraft equipped with radar and lasers to burn it down. This is something that we can do with our current technology.

@All - Would you use ocean destillation to lower the oceans, to create/ free up land mass. Course things will heat up, couldn't we also use the kessler syndrome to counter cool that scenario? It might be cheaper to use ferrofluid to create clusters of junk and let gravity bring it back down. Then trying to individually collect.

[@paxdriver]

I'm not so sure nukes in space would be good at clearing debris. A lot of the damage caused by blasting a nuke in an atmosphere or underwater has a medium to propagate through, and the EMP from setting off a nuke in space could be dispersed across the atmosphere, making it hard to keep track of all those orbits we just perturbed. I think nukes would be terrible at clearing orbital debris.

A per-kg disposal tax could be charged to launch providers. When the craft they launch re-enter the atmosphere, their tax is refunded with interest. The fund itself is managed by companies providing insurance for spacecraft. This pool of $$ funds collection and de-orbit activities.

[@nias2631]

Interesting idea. I wouldn't pay the interest though. They make profits off of their spacecraft performing services like Earth observation. If launch costs keep dropping you might see people launch useless to near-useless spacecraft into orbits that take years to decay. Basically they have an in orbit Treasury bond.

[@mm-rj3vo]

What if you placed a small asteroid in a highly elliptical orbit, very low on one end, very high on the other, and just let that go around the earth a few hundred times?

For smallish dense objects like nuts and bolts hitting them head on with a block of ice could work. The resulting water vapor would slow whatever goes through the cloud but it will disperse quickly under solar pressure nor is the slowing affect an entirely a bad thing.

[@Pystro]

Ice technically is an ideal material for such a projectile. Sadly, ice isn't really a renewable resource in space (at least around Earth). Since the ice only has to get to space, and not to orbit, you could maybe launch it from earth with a spinlaunch-like system or a linear accelerator. But that generates "fuel" costs for each intercepted object (where your fuel is technically electricity). And you'd need to enclose the ice in some fairing. That fairing would be guaranteed to de-orbit itself, but it still adds extra cost to each launch - even if the "fairing" is the outer most layers of ice of the projectile itself. Also, the nut or bolt or whatever could easily tumble upon impact with the ice, so that it's orbit after impact can't be accurately predicted. It would still be on a guaranteed de-orbit path, so it would only do a single pass through lower orbital space, but that added risk might be a deal-breaker.

[@calvingreene90]

@@Pystro Sub 3 inch objects like nuts and bolts are hard to track so the risk of them hitting something within the less than 2 hours they would have left in space after hitting the ice is significantly less then the risk of leaving him in orbit. Spin launch is a ludicrous absurdity; consider how much angular acceleration there be subject to when approaching launch velocity. Lift the water to orbit using the difference between maximum payload weight and actual payload weight.
