I'm wondering about a couple of things as they would relate to potential manned rovers for the Moon and Mars:1 - what would power them on long drives? solar / batteries, nuclear, methane/lox etc?
2 - On concepts I never see large radiators. Would they need large radiators to dissipate heat?
3 - what kind of range/duration of mission would they need to support?
4 - Could an exploration rover double as a construction vehicle? Or would dedicated rovers be more appropriate?
