I recommend sticking a long piece of conductor to the satellite, rather than banging on it with spaceships (;-))

What you get is smaller objects heading in different directions at different velocities, none of which are all that predictable, and in total more danger to objects in space than before and still significant danger to ground objects. What you want is to turn it harmless. This is done by gently attaching to it and then giving it a controlled push. I've been curious about what one could do over time just using the pressure of light from the ground, or enough light to gassify material to add delta V, however high power devices for this would also be effective weapons.

(anyone? there's a LOT of zeroes... ) I have project ploughshare on my mind, except kinetic, and it's less deflection on my mind than reducing a rubble pile to rubble, identifying the good pieces, and bringing them back. -- This song goes out to all the folk that thought Stadia would work: https://www.linkedin.com/posts/dtaht_the-mushroom-song-activity-6981366665607352320-FXtz Dave Täht CEO, TekLibre, LLC _______________________________________________ Starlink mailing list [email protected]<mailto:[email protected]> https://lists.bufferbloat.net/listinfo/starlink -- Bruce Perens K6BP _______________________________________________ Starlink mailing list [email protected]<mailto:[email protected]> https://lists.bufferbloat.net/listinfo/starlink -- David Collier-Brown, | Always do right.
