How OneWeb Lied About a Near-Miss Collision With a SpaceX Satellite (teslarati.com) 63

In a follow-up to a story previously reported, Slashdot reader Turkinolith shares a report from Teslarati: In the latest trials and tribulations of a SpaceX Starlink competitor that went bankrupt after spending $3 billion to launch just 74 small internet satellites, it appears that OneWeb knowingly misled both media and US regulators over a claimed 'near-miss' with a Starlink satellite. Back on April 9th, OneWeb went public with claims that SpaceX had mishandled its response to a routine satellite collision avoidance warning from the US military, which monitors the location of satellites and space debris. According to OneWeb government affairs chief Chris McLaughlin, SpaceX disabled an automated system designed to detect and automatically command Starlink satellite collision avoidance maneuvers to let OneWeb move its satellite instead. McLaughlin also stated that "Coordination is the issue -- it is not sufficient to say 'I've got an automated system.'" He also recently criticized the maneuverability of Starlink satellites, claiming that "Starlink's engineers said they couldn't do anything to avoid a collision and switched off the collision avoidance system so OneWeb could maneuver around the Starlink satellite without interference." As it turns out, OneWeb's "near-miss" appears to have been a farce and the company scrambled to promise to retract those statements in an April 20th meeting with the FCC and SpaceX.

In an apparent attempt to capitalize on vague fears of "space debris" and satellite collisions, OneWeb -- or perhaps just McLaughlin -- took it upon itself to consciously misconstrue a routine, professional process of collision-avoidance coordination between OneWeb and SpaceX. McLaughlin ran a gauntlet of media outlets to drag SpaceX through the mud and criticize both the company's technology and response, ultimately claiming that SpaceX's Starlink satellite was incapable of maneuvering out of the way. Instead, according to a precise, evidenced timeline of events presented by SpaceX to the FCC, the coordination was routine, uneventful, and entirely successful. OneWeb itself explicitly asked SpaceX to disable its autonomous collision avoidance software and allow the company to maneuver its own satellite out of the way after SpaceX made it clear that the Starlink spacecraft could also manage the task. The event was neither "urgent" or a "close call," as OneWeb and media outlets later claimed. SpaceX says it has been coordinating similar avoidance maneuvers with OneWeb since March 2020.

Most damningly, SpaceX says that immediately after OneWeb disseminated misleading quotes about the event to the media, "OneWeb met with [FCC] staff and Commissioners [to demand that] unilateral conditions [be] placed on SpaceX's operations." Those conditions could have actually made coordination harder, "demonstrating more of a concern with limiting [OneWeb's] competitors than with a genuine concern for space safety." Crucially, despite lobbying to restrict its competitors, "OneWeb [has] argued forcefully that [it] should be exempt from Commission rules for orbital debris mitigation due to their status as non-U.S. operators." In simple terms, OneWeb is trying to exploit the FCC to suppress its competition while letting it roam free of the exact same regulations.

    This is why we need the states to not only enforce their criminal defamation laws when appropriate, but have a federal one. If you are a PR person or corporate executive and blatantly lie to the public AND regulators your competition should be able to appeal to the US DoJ to have you criminally prosecuted. Sure, it would have a moderately chilling effect on public speech but we need that. We really do. People who are pathological liars in positions of power should fear their victims getting them tossed in prison and people who cannot articulate effectively what [NASDAP], Commie, Socialist, Fascist, pedo, etc. should not allowed to claim "my private definition is my right."

      I'm much less sure of that. Your argument here is motivated by one company that, if SpaceX is correct, is willing to lie and act in bad faith to try to gain a competitive advantage but is doing so against another company that has the power and resources to fight it.

    What are the actual odds any of these things collide if nobody does anything? They are all cube-sats right so not big.

    Space is big, yes LEO isnt as big but its still big. Inst the most likely outcome of these things appearing to be on the same path that they sail by each other at least 1000's of meters apart? How big a problem is this?

    • by queazocotal ( 915608 ) on Thursday April 22, 2021 @09:27AM (#61300556)
      The starlink satellites have a cross sectional area of around 20 square meters. The oneweb ones similar.
      This means that it's likely if you get within about three or four meters, there will be a very significant hit.
      A hit cannot be ruled out generally over the longer term if the intersection distance is under 100m.
      This is as the positional uncertainty of each adds to the possible cross sectional area, so yes, if you have two satellites that are forecast to come within 100m or so, you absolultely need to move them away from each other so that that risk is zero, if you can.
      Obviously, at some point, the decision has to be made of if both of them, or one of them needs to move, as if both move without coordination, they may manoever into a hit.

        Thanks for the quantification

      • Obviously, at some point, the decision has to be made of if both of them, or one of them needs to move, as if both move without coordination, they may manoever into a hit.

        Can't there just be rules for what gets moved when, to determine who moves and in which direction? And which take into account what happens if one party can't move for some reason (e.g. equipment failure)?

        • Given the vast differences in masses, costs, and performance of satellites, what may end up a trivial matter for one operator to move may be mission ending for the other.
          As these near misses are predicted days in advance typically, reasonable negotiations between the operators let them work out the best options between them.

          I'm sure there are a bunch of such "rules" - some formal, some more informal.

          But, obviously, the powered satellite must be the one to move if the other is using a solar sail.

      • On the other hand, the "altitude" of the satellites is not precisely held (not to the approximately 5 meters size of the satellite).
        And an orbit is about 40,000 km long, and a spacecraft "covers" only its length - so about one in 10 millions of it.

        As such, even a "close" pass have a very small chance of actual collision.

        The issue is however:
        -compared to the cost of putting two satellites in orbit, a small manoeuver (and with enough forewarning the manoeuver is indeed small) will solve all issues (satellites

          • by ClayJar ( 126217 )

            From the SpaceX filing, "if a maneuver was needed, typically a single in-track burn would be conducted to reduce collision probability". So, a slight prograde or retrograde burn which will slightly raise or lower the orbit. This would, of course, not just adjust the height of the orbit but also the timing, resulting in a reduction in the probability of a collision. Also, in case you might wonder, with SpaceX's avoidance system, "maneuvers occur approximately 12 hours before the predicted closest approach

            • Prograde will be more economical in the long run. It just forestalls the next station-keeping burn.

              If they're even calling ion-engine thrusts 'burns' these days.

              • Well they do still consume a "fuel" of limited quantity on board. You can't just "burn" these forever or till the electronics fail. Once out of Xenon, Krypton or whatever gas they are using, the ion thrusters are just as worthless and a normal fuel rocket without fuel. One has to wonder if you could make an essentially unlimited use thruster, or at least unlimited use till the compressor fails, by using a constantly running compressor powered off solar to compress the minute amounts of gas in LEO (LEO is no

      The probability of a collision was given as 1.3%. Even if it was 1/10th of that it would still be very much worth avoiding, given the amount of debris and havoc it could create.

    • Bigger than what we see for cubesats - even a 12U cubesat is only about 10x10x15 inches and spec'd at 2.9 lb per U.
      OneWeb body is roughly a 3x3x3 ft cube with solar arrays sticking out, total about 300 lb.
      Starlink body is about 3x6 ft area, and the solar array looks to be about 24 ft tall, total about 500 lbs.
      In common units, that's a washing machine and a fridge.

    • What are the actual odds any of these things collide if nobody does anything?

      Think of it like nuclear fission. The odds that any one Uranium-235 nucleus will decay is 50% over a period of 700 million years and the odds that this decay is spontaneous fission is about one in 5 million so to odds of any one nucleus undergoing spontaneous fission in any one year is about one in 3,500 trillion. That does not mean that nuclear fission is incredibly rare and nothing to worry about though. The reason that fission does happen a lot is that there are many U-235 nuclei in a lump of uranium an

        • I am forced to admit that it takes a metric fuckton of work to make U-235 produce a chain-reaction. It won't happen by accident.

          Not only can it happen by accident it actually has [wikipedia.org]. Of course today a natural reactor is just about impossible because the fraction of U-235 in natural uranium has decreased so much due to its faster decay rate. Also, it is not true to say that spontaneous fission is not the same a radioactive decay: it is a type of radioactive decay [wikipedia.org] with the branching ratio I stated for U-235.

          However, that's not really relevant because the number and density of satellites in orbit is not a natural situation. We have ca

I would suggest editors never allow content from them be a primary source; the summary (which presumably is the entire article) provides no actual information and is just a word salad. Typical of their content— stretch a sentence into 500-2,000 words with as much useless garbage and fluff as possible.

    As it turns out, OneWeb's "near-miss" appears to have been a farce and the company scrambled to promise to retract those statements in an April 20th meeting with the FCC and SpaceX.

    This comes from a filing by, well, SpaceX. Other, less Musk-boot-licky sources, checked on OneWeb's response - and in their own filing they say they made no such promise or offer to retract anything, and stand by the story. Also, complaints about SpaceX's behavior in this particular venture are not exactly peculiar to OneWeb. This may or may not be a publicity game, but the posted article is essentially an unquestioning parroting of the SpaceX official line.

    IMHO, what is needed is a standard set of regulations on this, conceptually similar to what exists on the water.

    At sea, there is a consistent set of relatively simple rules that govern which vessel is the "stand on" vessel, ie which one holds its course and speed, and which is the "give way" vessel, which maneuvers to avoid a collision. These govern interactions of all vessels at sea, from my little 27' sailboat all the way up to the world's largest supertanker. These rules include things such as when passing, the overtaking vessel gives way to the slower vessel, the vessel approaching the port side of another gives way, etc...

    The rules are partially practical (as a rule, most maneuverable vessel gives way), and partially arbitrary (sailboat on a port tack gives way to one on a starboard tack), but it leads to very little question as to who has to maneuver and who is to hold steady, in practically any situation.

    A conceptually similar set of rules would likely serve well in orbit, as things get more and more crowded.

    • there is a consistent set of relatively simple rules

      A high school friend of mine (who was a sea scout) insisted that one of those rules was "wood before plastic".
