Thanks! (I'm useless with orbital mechanics).
Obviously LLO is sufficient, since one can use solar sails or plasma
drives to go from there.

Isn't this primarily a timing problem? I.e. in the simplest

solenoids, firing a ferromagnetic brick?

How much power can we switch with a triggered arc discharge?

If this is not too much trouble on your part, please do.
