Space trash lasers, explained

Space debris is a huge problem, but we can fix it.

Humans are filling the space around Earth with trash. Most of this junk comes from abandoned satellites, discarded jet engines, and other mission-related debris. And when these objects unintentionally collide, they explode into thousands of debris fragments that can seriously damage operational spacecraft. With a booming commercial space industry that has put an unprecedented number of new satellites in space in just the past few years, our space debris problem is only getting worse.
Scientists worry about a situation called the “Kessler syndrome,” coined in the 1970s, where a runaway chain reaction of collisions and fragmentation results in a cloud of debris around Earth so dense that it threatens future space missions.
But there are a few options to begin clearing out the debris surrounding us, most of them united in a strategy of slowing the objects down enough to de-orbit them - forcing them to reenter Earth’s atmosphere to be destroyed. For the largest category of debris, fragments measuring more than 10 centimeters in size, one solution would be to send a small spacecraft into orbit, where it would rendezvous with the large piece of debris and slow its orbit either by pushing or pulling it.
For the smallest class of debris, which spans a range of 1 millimeter to 1 centimeter in size, there are two main ideas. One would be to put a physical sweeper into orbit to catch or slow these tiny, untrackable fragments. The other would be to introduce a cloud of metal dust into orbit to weigh them down and drag them into Earth’s atmosphere.
For the class of space debris in the middle, measuring between 1 and 10 centimeters, the idea of using ground- and space-based lasers as a cleanup method has circulated for years. In this approach, a laser would use radar to track a piece of debris as it flies into view and then blast a pulse of energy at it. The goal is to nudge the debris enough to disrupt its orbit, ideally enough to slow it down.
Right now, NASA considers this the most cost-effective way to deal with most space debris, but it will take commitment from the international space community to implement any space debris removal strategies.

[@LiamPieters1995]

Awesome, thanks a lot for bringing space lasers to people's attention! Really well-made video. I have been an avid supporter of space-based laser removal since 2018 and published a paper on its feasibility (small-scale debris removal using space-based lasers, by L.Pieters and R.Noomen). One small correction: at 6:18 you mention the space-based laser would have a more favourable angle wrt the debris object. While this is true, the orientation you show isn't the most favourable. You want to be hitting the debris objects as head-on as you can. This way you decrease the velocity, which makes the object de-orbit and burn up in the atmosphere the fastest. Let's hope this method gets realised in the near future.

[@collindwebb]

Yes, shooting a laser to push an object towards earth would just change its orbit a little; it wouldn't help de-orbit any debris we need to worry about.

[@tofferr]

Ah, so the ground based one would also be most effective at a head on angle... but to achieve that it has to go through so much atmosphere. Any idea what the optimal angle is for ground based? Other considerations?

[@LiamPieters1995]

@@tofferr ground based lasers are less worried about the geometry, since they can’t change their orientation anyway. They are always going to follow the target flying overhead for the max amount of time. Indeed, an object close to the horizon has better geometry but the laser spot size increases drastically as it has to traverse almost 1500 km to reach an object at 600 km altitude. I believe somewhere around 45 degrees angle the two effects balance out and the effect is largest

[@calexico66]

If you use laser ablation at the correct times it's possible to decelerate objects in orbit, the issue is that it can only be used for short periods, tracking targets and aiming with precision can be difficult. Unless the light is wider on one of the axes, making it easier to hit a target but could hit other objects that are close by.

[@sebjs3389]

I’m doing some policy research on space debris right now. All of these new technologies are really neat, but they’re so unproven right now and still in the early stages of development. The real problem going forward is space debris prevention-lessening the rapid creation of debris, as opposed to taking care of existing debris. The FAA has an excellent proposed rule working its way through the bureaucratic chain that would require commercial operators to dispose of their rocket bodies. Rocket bodies make up 95% of the mass of all space debris, and are by far the largest and heaviest pieces of trash in orbit (which makes them the most likely to collide with things and fragment). We need to first stop commercial companies from leaving their junk in space before we start implementing costly tech to deal with existing space debris.

[@weekiely1233]

Commercial launch providers don’t leave spent stages. SpaceX, ULA, rocket lab etc all de orbit their spent stages or place them into graveyard orbits. Most spent stages are from decades old missions from the U.S. and Russia in the Cold War

Does the tungsten dust cloud itself necessarily need to be in a stable orbit? It could be put on a suborbital trajectory or even an orbit with a very low perigee, do some sweeping over the short term, then re-enter quickly. Launching it westward instead of eastward would maximize the relative velocity when the particles do impact something, since nearly all satellites go east.

a big step forward would be moving towards full reusability/full de-orbit of all discarded hardware. single stage to orbit craft, or craft with fully reusable first and second stages, would flesh the idea out well. SpaceX has already commercialized the first half of that objective, and is actively pursuing the second.

[@YOOM100]

A system of space mirrors with boosters to guide its angle/trajectory in middle earth orbit would allow ground lasers with a renewable/constant power supply to bounce its beam at an X angle to hit the debris in lower earth orbit downward toward the atmosphere so it can burn up.

Problems: it's hard to target them from the earth, because you need to stay on target for a long time and you're trying to hit a penny with a pistol from 4 miles away - and it's hard to get the necessary power up into space.

For the next few days we heard absolutely nothing on the news. Later in life I was with an ex driving down the highway and seen the same fire in the sky but this time it was smaller.
