Report, if you have a problem with this page“ Mars is not Earth. It doesn't have a thick atmosphere to bend light and carry particles that reflect light around corners. It's damn near a vacuum here. Once the sun isn't visible, I'm in the dark. Phobos gives me some moonlight, but not enough to work with. Deimos is a little piece of crap that's no good to anyone. ”
