It can only be answered by the observation, as pointed out by @David Hammen, that some parts must remain warm. Apparently, this (tbs) thermal goal will not be met if the spacecraft remains in a penumbra for a given (tbd) duration. Such a demonstration would be a full answer to your question. | |

Nothing can tell us (at least me!) that smaller orbits within the allowed "box" would not give some desirable features (freedom of launch window? stability?...). So "non-issue" is a bit far-reaching conclusion. "Not very constraining" would be a correct qualification for the no-eclipse-allowed requirement. Also, the displayed orbit is just one representative example, not the actual one nor the "targetted" one. | |
