Thought stream: Minimum arc length of hidden (eclipsed) section of orbit; the higher the orbit, the slower the satellite needs to travel to maintain; I don't have experience with exactly the right math, but intuition tells me that regardless of distance from Mars, the related speed means that the time to traverse that arc will be the same ... maybe we could use an atypical orbit (passing closer to the planet while hidden?) to reduce eclipsed traversal time?
