Regulators Are Ignoring How Low Orbit Satellite Broadband Is Trashing The Night Sky

from the blinded-by-science dept


As previously noted, Space X, Amazon, and others are pushing harder than ever into the low-orbit satellite broadband game. The industry, pockmarked by a long road of failures, involves firing thousands of smaller, cheaper, lower orbit satellite constellations into space to help supplement existing broadband services. The lower orbit means that LO satellite service will offer lower-latency broadband than traditional satellite offerings, which for 15 years or so have been widely maligned as expensive, slow, “laggy,” with annoying monthly caps.

And while these services should absolutely help bring some additional options to rural Americans, nautical ventures, and those out of range of traditional service, folks shouldn’t get their hopes up in terms of broader disruption of the uncompetitive U.S. telecom market. The physics involved in satellite transmission means there will always be limited capacity and odd throttling and network management restrictions, meaning it won’t really make much headway in highly monopolized major metro areas. In short, the tech is absolutely a positive advancement, but it’s not going to be the game changer many think.

And there’s another growing problem with low orbit satellite technology. As we launch thousands of these micro-satellite constellations into space, the LO satellites are annoying professional and amateur astronomers, who say they’re interfering with space observation and important scientific data collection (especially at wide-field observatories). During the recent monitoring of the NEOWISE comet, for example, photographer Daniel Lopez showed what Starlink “photobombing” looks like in practice for those trying to track these sort of events in the night sky:

Not great. And it’s going to get notably worse. Amazon’s Project Kuiper constellation, for example, will eventually consist of 3,236 satellites, more than the 2,600 satellites currently in orbit. Space X’s Starlink project, in contrast, could ultimately consist of as many as 12,000 satellites all told. In some instances this is an even worse problem for slightly higher altitude LO satellites. And keep in mind this is just the testing phase… we haven’t even gotten close to broader commercial deployment yet.

While Space X says it’s taking steps to minimize the glare and “photo bombing” capabilities of these satellites (such as anti-reflective coating on the most problematic parts of the satellites), regulators at the FCC and elsewhere appear to be asleep at the wheel in terms of the broader impact on science and astronomy:

We don’t yet have any kind of industrywide guidelines,” said Michele Bannister, a planetary astronomer at the University of Canterbury in New Zealand. “We don’t have an industry body that’s producing good corporate citizenship on the part of all of these enthusiastic companies that want to launch, and we don’t have any regulatory setup in place that’s providing clear guidelines back to the industry.”

She added, “To me, honestly, it feels like putting a bunch of planes up and then not having air traffic control.”

No guidelines. Not just patchy or undeveloped guidelines. But none.

It won’t get mentioned by the Times, but part of the problem are regulators who base their decisions on ideology and not data. In telecom, folks on the “deregulate everything and free market magic springs forth from the sidewalk” side of the policy aisle have long tried to paint emerging broadband alternatives as near-mystical panaceas to justify deregulation. As in, “we don’t need regulation of telecom monopolies or consumer protection because this new technology X will create competition and fix everything.” It never works because the U.S. telecom industry is painfully monopolized and broken, yet that never seems to matter.

This performative policy happened most notably years back with broadband over powerline (BPL), which former FCC boss turned cable’s top lobbyist Mike Powell hyped as the “great broadband hope.” Powell routinely hyped the tech to justify his massive deregulation of telecom in the aughts, but willfully ignored the fact the technology was an interference prone mess causing massive problems for radio transmissions nearby. BPL failed, and you only need to look at U.S. broadband prices, rankings, or Comcast’s customer support to see how this worked out for everybody.

Low orbit satellite is far more useful and solid than BPL ever was, but I’m expecting to see it used in much the same way by the Pai FCC. As in: Pai’s crew will quickly rubber stamp Amazon and Space X’s ambition, hopeful that the added competition will help them retroactively justify their complete demolition of U.S. telecom consumer protections at the telecom lobby’s behest. As in, we didn’t need pesky oversight of monopolies because free market competition saved the day. But by Musk’s own admission Starlink won’t truly disrupt U.S. telecom because it can’t serve dense urban or suburban markets, meaning companies like AT&T, Verizon, and Comcast won’t be meaningfully disrupted, and reality and aspirational policy once again won’t line up.

When your top priorities are the maximizing of corporate revenues or the retroactive justification of bad policy based exclusively on ideology, the end result usually tends to lack… nuance. And in this case, this regulatory myopia could in many ways have unintended harm that goes well beyond the telecom sector and into the night sky itself.

Two senators have asked for a GAO review of a 1986 decision by the FCC that satellite systems were covered by a ?categorical exemption? to the National Environmental Policy Act, which requires an environmental impact statement. The exemption means that satellite systems seeking FCC licenses like Starlink are not required to undergo an analysis for their effects on the night sky.

In January, a paper by a Vanderbilt University law student attracted attention by arguing that the categorical exemption was inappropriate and that the FCC could be sued in federal court to overturn it.

As of January 2019, more than 128 million pieces of debris smaller than 1 cm (0.4 in), about 900,000 pieces of debris 1-10 cm, and around 34,000 of pieces larger than 10 cm were estimated to be in orbit around the Earth

Those satellites will be a very small addition to the existing hazards.

Re: Oh calm down

Sounds OK. The galaxy (and the universe) will be fine without humans all over the place, thanks.

Humans aren’t even very good material for filling up space. You "colonization for survival" fetishists would be better off going with something more efficient, some organism stripped down to do nothing but spread and reproduce. Rocket-building bacteria.

In your world, everything else seems to be a luddite distraction anyway.

until we kill ourselves off

Actually, all of "us" are going to die regardless. Nobody alive is moving to space, and definitely nobody alive is living forever. What you want is for some completely unrelated people to maybe come into existence at some future time. Those are fantasy people, unless specific actions are taken to make them real.

If we don’t dick around with your grandiose space colonization bullshit, and therefore there aren’t 15 gazillion humans wandering around all over the galaxy (until they kill themselves off), then absolutely nobody will in fact be any worse off. The interests of nonexistent people don’t count.

If you don’t take a course of action that creates somebody, you have not wronged that person. If you do take a course of action that creates somebody, then of course you’re responsible for what happens to them. And you have no way of knowing what kind of lives they might have, should you succeed in bring them into being.

And as for the interests of any possible set of "end times" inhabitants of Earth itself, you’re not going to save enough of them to rise above the noise floor. You might make their lives worse by burning resources on this colonial horseshit, or by provoking fights over who gets to run it.

soon or later we’re going to colonize the galaxy.

Well, that’s circular, isn’t it? Either you do it or you don’t. Duh.

And the bottom line is that nobody should care.

Lights in the sky seem a small price to pay for that.

Not to people who aren’t caught in some kind of fucked-up, mindlessly expansionist, species worship thing.

… and not, by the way, that these particular constellations will contribute in any way to any colonization objective you might have. They are simply an application of well-understood technology to an unrelated problem. They will have no spin-offs. All they’ll do, if they do anything at all, is make it easier to get onto TikTok. Not every fool thing anybody does in space necessarily contributes to your Grand Takeover.

120 years ago you people would have been the ones moaning about how these newfangled "airplane" things are going to mess up view of the clouds.

On your own values, aviation adds very little value and should probably be cut way back. Steamships and trains made the modern world; they enable industry that can get you off the planet. Most airplanes just make it easier to go be an obnoxious tourist, and/or to drop bombs on people. Those are distractions from taking over the galaxy as soon as possible. You should only care about the very few airplanes that directly contribute to colonization.

Or are you just rhetorically masturbating – spouting text that’s meant to put down your imaginary opponent – because it feels good, without having any point of your own to make?

You aren’t the only one who does this. Y’all seem to be a sub-species of troll, who get their kicks from imagining that they make other people feel bad, but fail to accomplish even that, as they attack imaginary strawmen who don’t exist.

…and with iron alone it’s not going to be a decent dyson sphere. I mean, there’s the "poor dyson sphere builder’s solution" of just covering the output of a star with sufficient numbers of floating habitats but that’s cheating. What you really want to make a dyson sphere or better yet, a matrioshka brain, is some form of material with sufficient tensile strength to actually create a full enclosure of the star.

We’re looking at some fairly exotic forms of matter being required. Larry Niven’s scrith from his "Ringworld" books, perhaps, or some other form of pseudoscientific impossibility…

naschsays:

Re: Re: Re: Just for fun

I don’t think you need anything all that exotic because there’s not a great deal of force applied anywhere. Consider starting with one satellite in an orbit similar to Earth’s. Then attach another satellite to it, and another, until there’s a ring all the way around. Then start building toward the "poles". Other than impacts, all it has to withstand is the sun’s gravity, which is almost nothing at that distance.

Anonymoussays:

Re: Re: Re: Re: Just for fun

Low force only applies while in an orbit, which has a centre that is coincident with the centre of the Earth. To stay in a fixed position relative to an orbiting object and out of the orbit plane takes force. In your example, the bits above the the poles have a full one G of force towards the Earth, because they have zero orbital velocity.

naschsays:

Re: Re: Re: Re: Re: Just for fun

In reality (wait is that what we’re talking about?) nobody would be likely to build a Dyson Sphere. Just a ring would have millions of times the surface area of Earth. By the time we could build such a thing and actually use all that space, it would probably make more sense to go build one around another star than to go full Dyson sphere. IMO anyway. It would also be problematic to build one here because, well, the Earth is in the way.

Anonymoussays:

Re: Re: Re: Re: Re: Re: Just for fun

Read whatever it s orbiting instead of Earth.

The only parts of a sphere or ring, not subject to some gravitational force are those at orbital velocity, and on the plane of the orbit at exact orbital height. While the forces are small, satellites are subject to gravitational torques because parts are outside the line that defines the orbit. Part of satellite design is distributing its mass so that it keeps the desired bit pointing to whatever it is orbiting.

Oh another problem with Dyson spheres, and ring worlds, ,their position are not stable, and a nudge off centre results in a drift in that direction. Also, a ring world rotating at orbital velocity has a problem for living on, effectively no gravity at its surface. Rotate it fast enough to create artificial gravity and whatever it is made off requires considerable strength.

Scary Devil Monasterysays:

Re: Re: Re: Re: Just for fun

"I don’t think you need anything all that exotic because there’s not a great deal of force applied anywhere."

Put a trillion tons of iron around the solar system and I’ll show you some impressive tidal force torque, even as far out as the outer asteroid belt. Even your idea about an earth ring will end up shredding every known material in a single lunar revolution.

The main issue is that anything remotely solid will end up undergoing regular and persistent deformation due to gravitational shifts – and the weak gravity of the gas giants will be anything but negligible if it acts on enough mass.

So that means you need something either flexible and durable enough to survive the constant flexing and magically hold it’s position without the still-standing poles of it just collapsing inwards to the sun – or something rigid and indestructible enough to not give a shit about the fact that every time one of the gas giants swing past enough forces sufficient to move earth-sized planets will be tearing parts of the dyson sphere in multiple directions.

Conventional theory states that in order to build a dyson sphere you need to strip-mine and convert every planetary body in the star system into shell material. If that’s the tech we are assumed to have then the shell will be built out of something not covered by the periodic table – i.e. exotic matter, because i doubt we’ll find transuranic elements solid, lightweight and stable enough.

If we ever do find a civilization capable of encasing a star we’d better hope the god-like beings in charge of that are friendly or at least uninterested.

Scary Devil Monasterysays:

Re: Re: Re: Re: Re: Just for fun

Addendum:

Larry Niven’s "Ringworld" solution is slightly more feasible. You can spin it to provide stability and centripetal force, something which would be difficult to manage with a sphere. That solves a lot of problems but introduces even more demand on the durability of the material.

Anonymoussays:

Re: Shift left! If I do we will miss the runway! Well...

I think you are grossly underestimating the amount of space up there for these satellites. It would take precision beyond the level of a 2 mile sniper shot to try to hit one of these when returning to earth. Sure 20,000+ LEO satellites sounds like a lot, but there is a lot of space up there for them to sit in.

The lowest diameter of SpaceX satellite orbit of their initial 4425 satellites is about 9000 miles giving a total sphere surface area of about 250 million square miles. If you flattened that out in a 2d plain, that would be about 56,500 square miles per satellite.

The "challenge" of vectoring around these, is about equal to vectoring around a single Tesla in a target the size of the entire state of Michigan. Not a concern in the least.

Paul Bsays:

Re: Re: Shift left! If I do we will miss the runway! Well...

I mean the real issues are:

If you do hit one (or anything bigger than a screw) its a bad day for the ship taking off.

The units are causing various ground based platforms a huge amount of problems since they are trying to detect the wobble caused by planets going around stars by red/blue shift. This is a huge issue for things that require good long exposure times since the satellites are setup in a fairly standard pattern to give good global coverage.

Anonymoussays:

Re: Re: Re: Shift left! If I do we will miss the runway! Well...

The earth is a sphere, not a circle, and these satelites are not in an equatorial orbit. You need to use surface area of a sphere, not diameter of a circle. In fairness, you do need to subtract some of it, since they don’t quite make it to the poles.

By your logic, the 7.7 billion people on earth would each only have 0.2 inches of space to exist.

Are you claiming there is no threat? Debris Avoidance Maneuvers are not cheap, they are not uncommon and are used to avoid the junk they can detect. Small objects at high velocity are not detectable with present technology and are capable of significant damage. But hey – let’s go on a space vacation because it is so safe and all.

Eldakkasays:

In the short term this is going to be a huge problem for astronomers. But not in the medium (10-30 years) or longer term. Why you ask?

Because the primary thing that all these launches are doing is bringing down the cost of entry to space. SpaceX has already brought it down massively from $200 million for a large satellite launch (sole use of the launch vehicle) to something like $60 million for sole (reusable) use of the launch vehicle. And it’s still coming down. It’s even been reported (not sure if this is from SpaceX or just speculation) that it costs SpaceX less than $60 million/launch, but since everyone else is still paying $100-200 million at present, i.e. lack of competition, they have undercut their rivals enough for the time being, leaving a comfortable margin for themselves.

Once Starship and New Glenn and all the others come online (e.g. follow-on to Ariane 6, ULAs project, etc.), prices will come down even further.

In the last 20 years, there has only been one major optical telescope launched into orbit, Hubble, due to cost. With its replcement, JWST still not launched, not until next year at the earliest.

In a decade, I think it will be relatively cheap to launch 4m(Hubble)-8m(JWST) class telescopres into orbit. Might not sound very big, but Hubble at 4m is better than any of the existing 8m-10m ground based telescopes, like Keck of VLT (operating independantly, one the hook em up into their interferometry configurations, combining 2 Kecks or all 4 VLTs into a single scope they are perhaps better). Therefore even small collaborations will be able to launch these types of telescopes into orbit themselves. With the larger launch vehicels like Starship, 10m-class telescopes could be launched into orbit relatively cheaply for larger colloborations such as 30m-class scale collaborations. Sure, they don’t have the serviceability or upgradeability of ground-based ‘scopes, you can’t just add more experients to them, but you may be able to launch a new scope per colloboration every 10 years or even more often with the newer instrumentation.

And long term 30+ years, with this declining cost in access to space, they may be looking at building even larger telescopes on the moon. Perhaps even bigger than the 30m-class that are currently under construction that a lower gravity would allow.

I see it as a short term pain for the astronomers for a medium to long term atronomical (pun intended) gain with routine space-based or even moon-based ‘scopes.

And, hey, if the costs to space don’t come down much, then the satellite swarms won’t be profitable. They’ll cost too much to maintain the swarms in LEO, they’ll all just deorbit and burn up in the atmosphere. ~3 years after they stop replenishing the swarms due to cost, their LEO orbits will decay and they’ll all burn up, thus opening up the night sky again.

So either it’ll be profitable because access to space is cheap, thus opening up other realms of possibilities cheap space access allows, or they won’t and they’ll remove themselves from the night sky in a few years anyway, bringing us back to the status quo in 10-15 years.

Eldakkasays:

Re: Re:

Even with 100,000 satellites in LEO, all improbably in the same orbital plane (~428km for my calculation, but obviously they will be spread across several planes from ~250km to about 1300km depending on the particular companies plan, not all lumped into the same plane, thus the separations will be even greater because there will be far less per plane than I’ve calculated, but more complex as there will be several nested spheres of orbits with greater separations to pass through), that still puts them at an average separation of 140km. Plenty of room to launch a rocket through.

Total bullshit.

This is not a problem with "micro satellites" (and at 500 lbs a pop, calling a starlink satellite a "micor satellite" is a bit of a stretch). This is a problem with astronomers failing to apply the plentiful solutions. Done right, this is a non-problem.

First off, you know where you can see these streaks with your unassisted eyes? Nowhere, that’s where. Not because they’re too dim, but because THEY DON"T EXIST. They are purely an artifact of long-exposure photography. From the length of the trails, at least multiple seconds. This is how you have to take photos of dim scenes when you use silver-halide photographic plates, as astronomers used to do. You know who does that nowadays? Almost nobody. Instead they use light sensitive electronic sensors (CCDs, bolometers and other depending on the EM frequency you want to capture). To get the shown effect, you use low (ish) sensitivity sensors with a high integration time (the time over which the sensor builds up the charge representing the light the sensor is receiving). For a number of reasons – one of which is the ease with which the satellite images can be removed and replaced by the background – this is, to me, a very dubious approach. Probably penny-pinching to avoid the cost of better sensors. A much better approach would be a higher sensitivity sensor (preferably with more bits-per pixel than the desired output), lower integration time and you take multiple shots then sum them using a filter that removes the anomalies. If you add an exact knowledg of your position and the exact location of the starlink satellites when you shoot, an even better filter could easily be developed.

There is no reason for this problem, other that bad technique by the astronomer, that would take more that a few thousand dollars at the outside to fix (for better sensors, which would be a boon to the astronomers anyway). Even if it were impossible to fix at the astromer’s end (which is isn’t), I would put the (great) economic value of the starlink system – which will support unconnected people and communities around the entire globe, eventually, above the narrow interests of these astronomers. To those who moan an complain about this, I say: Boo hoo, cry me a river, you are just a bunch of selfish, NIMBY neoludites.

Anonymoussays:

Re: Total bullshit.

It’s quite clear you have no idea what you’re talking about. The problem is simply that finding objects is hard enough as it is. The problem is very simple: most things worth studying are dim and hard to see under the best of circumstances. We need to set up in isolated places because light pollution is a problem. By your logic, it ought to be just as easy to do astronomy in New York City, and the fact we have to set up in places like the Atacama Desert is just because we’re too cheap to use better sensors.

Plus, what happens when the satellite is right in front of the object we want to study? When you have thousands of them, that’ll happen an awful lot, and the worst part is we won’t even know all the times it happens: how many dim objects will be missed because we never noticed them because of the glare of satellites?

As for neoluddites, you do know most astronomers are into, you know, space, right? We support things like NASA, Mars exploration, and let’s not even get started on space telescopes. So no, that’s a ridiculous argument: just because you don’t understand the problem doesn’t mean it’s not there.

Scary Devil Monasterysays:

Re: Total bullshit.

"There is no reason for this problem, other that bad technique by the astronomer…"

So as a layman with no experience in the field your argument is that the highly paid professionals whose job has been to consistently improve their detection techniques are doing it wrong?

Bravo. You should put this hypothesis of your up for publication and take away your nobel prize of physics. /s

Meanwhile, in the real world, it’s not that simple. Any object in orbit which reflects light adds a major factor of error. The light scatter alone is enough to drown out the sort of light astronomers try to detect, in much the same manner the headlight of an oncoming car a mile down the road will drown out the light of the firefly the astronomer tries to observe a hundred miles down the same road.

"I would put the (great) economic value of the starlink system – which will support unconnected people and communities around the entire globe, eventually, above the narrow interests of these astronomers."

One of the low-albedo slow moving object types said astronomers are looking for would be medium-sized asteroids on an intersect orbit with earth. Dinosaur killers, in other words. Statistically we’re well overdue for one, and whether we spot it a century away or ten years away will mean the difference of whether we as a species will live or not.

It takes a special kind of stupidity to value the short-term economy over the actual survival of the species.
The universe isn’t safe. There’s almost no place in it where we won’t either freeze or burn. Extinction events are a rule, not an exception. Sooner or later this planet will become uninhabitable in a hurry, and at least a few of the likely causes can be spotted only by astronomers.

The only reason anyone would argue differently without just being ignorant and willfully blind is by the assumption that pot odds are a trillion-ton ice mountain won’t be falling on our heads within the next century and the evaluation that it isn’t worth giving a shit about what happens to your great-great-great-grandchildren or the human race as a whole.

That would truly take "Fuck you, Got mine" to the next level.

Either that or – and this is lamentably not too uncommon among a certain subset of fuckwit – as long as the current generation does all right for itself they truly couldn’t care less if todays actions mean the human race ends in fire from the sky a century or two down the road.

As I said, it takes "Fuck you, Got Mine!" to the next level.

Salutatory for Satellits.

So, yes, there’s an opportunity cost to putting up a great number of low-orbiting satellites.

That said, it’s looking like SpaceX may actually pull it off. There’s people beta testing their satellite internet presently.

We all know the broadband space is in desperate need of disruption, and if a satellite internet provider can do so, I’d like to say "more power to them!"

Even better, we’ve got more than one competitor in the space (no pun)!

In the future, I expect using satellites for astronomic observation will become more common, which completely ameliorates the ground-level photography issue. On top of that, there’s a ton of cpu-drive techniques for getting non-static objects out of images.

We have so much to gain, and ready solutions to every complaint. We should be going full-steam ahead on satellite internet, in my opinion.

That alright where it is just the appearance that matters, but in astronomy a little spot of light is significant, as is its position relative to other little spots of light. Also, image differencing for spots of light are used to detect moving objects in the night skies. Spaces is about to introduce a lot of noise into images where low noise, at least on clear nights, was expected.

This was addressed in the second paragraph:

"And while these services should absolutely help bring some additional options to rural Americans, nautical ventures, and those out of range of traditional service, folks shouldn’t get their hopes up in terms of broader disruption of the uncompetitive U.S. telecom market. The physics involved in satellite transmission means there will always be limited capacity and odd throttling and network management restrictions, meaning it won’t really make much headway in highly monopolized major metro areas. In short, the tech is absolutely a positive advancement, but it’s not going to be the game changer many think."

Something needs to disrupt the industry, but this won’t be it.

"Something needs to disrupt the industry, but this won’t be it."

Worse, it’s yet one more of those "want to have" solutions meant to circumvent what people "need to have".

There are plenty of ways to run a full-coverage landline all over a continent. Problem is the cost of that will be loaded on the taxpayers as a whole rather than paid for by any single corporate entity simply because the roi on supplying communication to small, scattered rural communities isn’t going to be significant in the short term. Since it won’t pay for itself to supply communication off the beaten track those communities remain isolated.

"It is then unfortunate that the taxpayers as a whole have been paying toward that lofty goal…"

I re-read what I wrote and it didn’t come out quite right.

I’m not opposed to tax payers paying for core infrastructure – as a european I expect that’s what my taxes are going to – but in the US such projects would be considered an abomination.
To some extent that would be correct thinking as the US in quite a few memorable cases where they tried churning out massive government public-interest subsidies simply couldn’t stop from turning it all into a pork barrel project.

The issue I’m seeing here is that starlink constellations is the effort of private industry to cover infrastructure gaps which should have been the government’s responsibility and as a result of that what you get is an overpriced and overhyped "pay more, get less" solution rather than a sustainable one.

Fiber in the ground sticks around. Starlink doesn’t and instead has to rely on someone perpetually firing new cubesats into orbit.
