So if this area is permanently dark how is the rover powered without solar panels?
Nuclear Isotopes
I believe that the rover will have solar panels, and possibly storage batteries that will power the rover in the dark. I don’t know that the rover is actually going to go down into any craters, their sides may be too steep.
It will be able to catch sunlight unless it goes into a crater. Someone can correct me if I’m wrong.
Will it hold up in the cold? What about rover material properties at those temperatures? Iron becomes brittle at below zero. Do other materials have strange, unexpected properties?
