Not sure a "hibernation" mode would take that much less energy to keep the systems cool and happy. Ideally, the solar panels should make conserving electrical power less of an issue (unlike some other manned space systems that use fuel cells).
Eww. Worst lunar surface rendering ever. The key in these illustrations is to use a stock photo as a background. Also texture maps on the vehicles (not a strong suit of mine, either.)
This company was offering models of the system, although they seem to have temporarily discontinued it.
