Re: steering


Inertia wheels are used to reorient communications satellites in
Earth orbit.
Inertia wheels are not used for linear acceleration in space for reasons
that are probably reasonably obvious to a reasonable job applicant.


It depends on the job. A physics job, maybe yes. An electrical engineering
job, maybe. Somebody selected from the general population, probably not.
The idea of the center of inertia staying in place is actually very subtle.
