Space really should be a neutral ground like Antarctica. Especially since the consequences of space debris might trigger the Kessler effect [1], denying humanity future access to low-earth orbit for the considerable future. 1. https://en.wikipedia.org/wiki/Kessler_syndrome

What is the point of any treaty with the current US administration which does not play by international laws? Rules and laws that the USA itself spearheaded after WW2.

The Soviets attached cannons to space stations, and the Chinese are believed to have deployed space-based weapons. The USA is actually a laggard in this field.

Exactly. Most of these things are just big world politics. Same for AI, btw. "OMG dont do this this is horrible" as the other country does it and hasn't talked about it or haven't been caught doing it.

It's all information wars at the end of the day, and HN is not impervious to any of it. Its like OAI and Anthropic saying we should all slow down AI model work. Like, lol, right. As if others would do that.

The only way to be safe, so far, has to be that everyone is second guessing everyone's capabilities - not "ahah they dont do it anyway lets go crush em".

Same as nuclear weapons basically, we all have them.

> Adding a few thousand more pieces of debris would not be even remotely as bad as using a tactical nuclear weapon in war would be. The worst effect would be a nuclear weapon in space. The resulting EMP would probably fry more than enough electric and electronic devices to throw back whatever country is hit by it by decades .

If someone launched a nuke in space how would other nuclear powers react? I doubt they would assume "this is probably just an EMP and not a direct nuclear strike on our territory"

If you had time to plan it, you'd probably want to put the warhead on a satellite launched by a normal satellite launcher. It'll look benign until you detonate it.

There is the Outer Space Treaty (1967), which forbids placing "nuclear weapons or other weapons of mass destruction in orbit or on celestial bodies or station them in outer space in any other manner", but you can get around that by saying that it's just a conventional weapon, not nuclear or WMD. If it's for space to space combat, you could say that any weapon is potentially a WMD due to the Kessler potential, but if…

Realistically pretty much anything in orbit is a viable space to space weapon (for related reasons all space propulsion is ITAR controlled) so it was never practical to ban them. Space to earth, maybe, but that isn't unless it hits vague 'WMD' categories, and I'm not sure space to ground is necessarily what the US is declaring here. I suspect whatever capability the US is referring to is far more "counter space" than…

Every spacefaring nation seems to have had their go in blowing up satellites using anti satellite weapons [1] and smashing satellites into other satellites [2]

It's most likely space-based missile defense, perhaps DOD secretly revived the Brilliant Pebbles (https://en.wikipedia.org/wiki/Brilliant_Pebbles) program?

People hear "space weapons" and think Rods from God (https://en.wikipedia.org/wiki/Kinetic_bombardment) but hitting a precise target on the ground from space is really hard, like tying to hit a bull's eye from hundreds of miles away. The more practical application is missile defense or anti-satellite stuff.

As long as they're OK with China and other countries having space weapons then all is fine. Everyone is equal with - they all have nukes in space sitting over each other's countries waiting to drop. This is fine.

> Space really should be a neutral ground like Antarctica

"They are dismantling these systems because they do not expect they will ever have a use for these weapons. Not because chemical weapons are immoral. Because they are ineffective, whereas landmines, cluster munitions and nuclear weapons are assumed to have future uses. Morality was never at issue, effectiveness was.

That has some big consequences, most of which are actually unpleasant. It means that efforts to ban ‘immoral’ weapons that are effective will likely never succeed. The model that activists thought they were building on is a foundation of sand – the only way you ban weapons is after they are basically useless anyway (to cut that point finer: you get to ban weapons after they stop being useful to the great powers, who may then enforce the ban on smaller states). The idea that we might summon up enough moral indignation to set these weapons aside seems unfounded. We are not nearly so moral as my high school teachers imagined, nor are we so cowardly as a ‘Fremen apologist’ might think. We’ve simply made an amoral calculation about effectiveness" [1].

> the consequences of space debris might trigger the Kessler effect

Kessler is terribly understood in the public consciousness. There is no known solution for generally denying access to space using anything less than orders of magnitudes of the resources it would take to just continually shoot everything down. In high orbits, Kessler can deny specific orbits–GEO is a notable one that we could generationally fuck. But the idea that nobody will be able to go to space, much less LEO, is wrong and distracts from the real issues with space-based weapons, especially ones in LEO.

It’s paywalled. Is anyone reading it before replying here?

It's not paywalled - it's the BBC. But maybe try CNN's version: https://www.cnn.com/2026/09/15/us/us-space-force-weapons-cap...

I have been getting occasional paywalls from the BBC asking to pay to read articles. Clearing cookies does remove the paywall for a while so I think it's some sort of A/B test they're running.
