    What are these units relating the rate of use of fuel: m/s? Is it the velocity of expelled reaction gas?

      I think that's delta-v.

        I’ll take your word for it; I’m not familiar with satellite-speak.

        But to me,

        “In this case, the fuel required to conduct such a maneuver is ~105-106m/sec”

        means that they’re talking about a quantity of fuel, but giving a velocity.

      > Russia is trying to determine if the US is useing these particular satelites for real time targeting and weapons direction on Russians, in Russia, which if true,then makes it there absolute right to destroy the sattelite weapons systems, and legaly target there operators, wherever they might be.

      Would that actually be true? How does delayed vs realtime change if they are legitimate targets?

        one is meerly satelite info that is evaulated for strategic or even tactical information use, the other is a literal weapons system component used for killing humans,in a situation that would otherwise be impossible without the satelite, which is an act of war, ie: "killchain", with no proxy , but the false claim of lack of resonsibility. the case in point likely involves drones that are fired from mainland europe into russia, with complete american command and control, but atributed to ukrain, which if russia can prove conclusivly, will then have consequences, legal and military, though of course, as usual, everybody will blame somebody else, and nobody will admit anything

      does everyone who gets photographed by a satellite get an "absolute right" to destroy the satellite then? Bit of a slippery glidy no-fun slope

        When those photographs are used to commit acts of war, yeah
        • yread4 hours ago
          shh there is no "war"

      Why should the American government, quite critical about the Ukrainian government, use Finish satellites for this?
      • Yiin3 hours ago
        they might be critical in public, but they still provide a lot intel

      Not even Putin is stupid enough to attack American satelites openly, regardless of his "absolute right".
