Isn't the cost of taking down a satellite lower than putting it up?

The problem would be all the debris up there. Maybe destroying one satellite would destroy them all.

    Probably not for Starlink. You’ve got mass-manufactured satellites in a constellation launched on a reüsable, profitable platform on one hand. And on the other hand you have experimental expendable ASAT weapons.

      How much does it cost to launch ball bearings into an intersecting orbit? They are even cheaper to mass-manufacture.

      The anti-satellite side has a budget hundreds to thousands of times cheaper, based on average ball bearings to satellite density in orbit, with a decent spread and multiple orbit intersections per day.

        Approximately as much as a finished satellite or block or gold of similar mass. The bulk of the cost is in launch and aiming.

        Imagine you're standing on a simplified earth that's a perfect sphere, with no air resistance, and have a gun that has a muzzle velocity of orbital speed.

        There are 40,000 SUVs randomly located on the planet.

        You fire randomly in the horizontal plane.

        What's the probability of you hitting an SUV, and not yourself in the back 84 minutes later?

        The earth is big. The probability isn't zero, but for any given orbits period it is low. And both the ball bearings and the satelites will re-enter after a while.

    Is not changing BGP route cheaper than taking down a satanlite ? Sorry, satellite.
