Russia May Have Just Shot Down Its Own Satellite, Creating a Huge Debris Cloud (arstechnica.com) 176

Posted by BeauHD from the irresponsible-behavior dept.
An anonymous reader quotes a report from Ars Technica: The seven astronauts and cosmonauts onboard the International Space Station sheltered inside their respective spacecraft, a Crew Dragon and Soyuz, on Monday morning as the orbiting laboratory passed through an unexpected debris field. This was not a pre-planned collision avoidance maneuver in low Earth orbit, in which the station would use onboard propulsion to move away. Rather, the situation required the astronauts to quickly take shelter. Had there been a collision during the conjunction, the two spacecraft would have been able to detach from the space station and make an emergency return to Earth. Ultimately that was not necessary, and the astronauts reemerged into the space station later Monday. However, as the crew on board the station prepared for their sleep schedule, Mission Control in Houston asked them to keep as many of the hatches onboard the space station closed for the time being, in case of an unexpected collision during subsequent orbits.

It appears likely that the debris field that had alarmed flight controllers on Monday was caused by an anti-satellite test performed by Russia's military early on Monday. [...] It appears that Russia launched a surface-to-space Nudol missile on Monday, between 02:00 and 05:00 UTC, from the Plesetsk Cosmodrome in the northern part of the country. The missile then struck an older satellite, Cosmos 1408. Launched in 1982, the satellite had been slowly losing altitude and was a little more than 450 km above the Earth. This is a large satellite, with a mass of about 2,000 kg. As of Monday afternoon, US Space Command said it was already tracking more than 1,000 pieces of new debris. Although the satellite's altitude is higher than the International Space Station, which is about 400 km above the surface, a kinetic impact would spread a large cloud of debris. Satellite expert Jonathan McDowell believes the Cosmos 1408 satellite is the likely candidate for the space station's ongoing debris event.

During a daily briefing today, US State Department Spokesman Ned Price said the test had created more than 1,500 pieces of trackable debris and hundreds of thousands of pieces of un-trackable debris. "The Russian Federation recklessly conducted a destructive satellite test of a direct-ascent anti-satellite missile against one of its own satellites," Price said. "This test will significantly increase the risk to astronauts and cosmonauts on the International Space Station as well as to other human spaceflight activities. Russia's dangerous and irresponsible behavior jeopardizes the long-term sustainability of outer space."

        It's important to consider the relative level of screwery. Before jumping to conclusions it might be good to investigate just how much important orbital infrastructure Russia has compared to the other major powers, and how dependent they are upon it. Even if they'd rather not destroy it, they might be sending a message that they're willing to if the competition doesn't back off.

        Basically, if your military and industry is heavily dependent on orbital infrastructure, and mine is only modestly so, then I will dramatically reduce your advantage if I destroy the viability of orbital infrastructure for everyone. It's akin to burning cities or salting fields when you know you won't be able to hold them, but your opponents will. A time-honored military tactic.

        Right now the space race is heating up again, and in all likelihood the early adopters will be able to claim all the really valuable real estate before anyone else even gets off the ground. Shackleton crater on the moon, Ceres and 16 Psyche (likely representing a huge portion of the total wealth of the Belt between them) and the handful of other really large asteroids, etc. The US is well positioned as the home of SpaceX, China and the EU are busy throwing lots of resources into catching up. And Russia is still suffering from the ongoing collapse of the Soviet Union, while their space program is crumbling under poor management, and has maintained an adversarial relationship with Musk and SpaceX since before SpaceX existed.

        Throw in the fact that Russia controls vast untapped mineral wealth here on Earth, all of which would be rapidly devalued by asteroid mining, and that they alone among the major powers stand to benefit substantially from global warming, and they could very reasonably conclude that their long-term interests are best served by denying their competitors access to space until they're positioned better positioned to compete on an equal footing. At the very least they're in a position to threaten such an action for political leverage, with the competition knowing full well that that they have no great reason not to.

        Now, obviously I don't know that's what they're doing - this could really just be a reckless anti-satellite weapons test. But it seems very dangerous to assume that's all it is.

          The idea is not to win, but to make the opponent bleed.

          (just as the USA did, bleeding the Soviet Union dry in an arms race, space race, ... during the Cold War).

        • It's also possible that Russia is aware that it's getting left behind in terms of space tech and industry (US, China, EU, Japan, and even India, etc are catching up or already passing Russia when it comes to Space) and it's trying to make sure nobody else gets to ""play" in space when it's getting badly left behind.

    The US, Russia, China and India have all done satellite tests of a similar sort. And all have created bad debris clouds. That said, the US and India tests were both at comparatively low orbits, so the risk of a long-term debris cloud was smaller. The Indian one was especially low, at only about 300 KM up https://en.wikipedia.org/wiki/Mission_Shakti [wikipedia.org]. The higher up the orbit, the more chance that there will be a lot of debris that takes a very long time to decay. That said, even given that, there's always a substantial danger here that some debris will move into much higher orbits. No one should be doing this.

          Surely. Sand is just a cheap alternative. The point isn't that you need sand, Tungsten Carbide or Depleted Uranium. The point is that just about any hard and small material you place in the retrograde orbit in different orbital shells is going to take care of a lot of satellites. Getting any hard material into an orbit where it can simply "interact" with satellites will do the trick.

          • You don't need to just get the particles into orbit. They need to stay there.

            The atmosphere doesn't stop at the Karman Line. It just thins out. The friction at 300 km is negligible for a satellite but significant for a grain of sand. It will deorbit in a few months or a year.

            A particle of tungsten has a quarter the area of a grain of sand with the same mass, so it will experience a quarter of the friction, stay in orbit four times longer, and therefore four times more likely to hit a target.

            • Yup, another way to say the same thing is, for a given size, the tungsten will have more mass and thereby be less affected by drag (the more mass something has, the higher its terminal velocity -- a plastic ping pong ball falls slower in air than a lead ball of the same size.) It will also impart a higher force in collision.

              • Also, the "hardness" is completely irrelevant.

                An impact with a particle in a retrograde orbit will have a delta-V of roughly 20 km/sec. It will immediately turn into a jet of plasma with no atomic structure.

    The more SpaceX and other US companies drive down the cost of access to space and have tens of thousands of satellites in orbit, the more competitors like China and Russia will be tempted to deny space to everyone using debris. Currently there's a modicum of balance in space but if it becomes much more valuable to the US than to competing nations then making earth orbit operations non-viable becomes relatively more attractive. Doing so can even be deniable; you just stage some accident and say "whoops, sorry".
