Re: This seems like a good argument for ion drives
I discussed this kind of application (at a space conference) with one of the major ISS designers (prior to ISS happening). He agreed it was a good application in principle, e.g. avoiding the “structural rattle” associated with (more impulsive) traditional gas-expansion attitude-control options.
But the aerospace industry is renowned for its conservatism. Who needs wheels when there is so much accumulated experience with skids? And risk assessors love accumulated experience.
One reasonable question (addressable) regards possibility of ionisation and hence structural charge.
