The idea of human colonization of space is just as much a pipe dream now as it was then. But they are still cool renderings.
yeah, actually there is something you can't do with a robot/crawler and a camera: Pick up a rock and take a look at it. Bring it back inside your vehicle/habitat and feel the surface. Break it open and feel the difference between the weathered exterior and a fresh break. Taste it (yes I am serious). Climb up on top of a boulder at the base of a rock outcrop and bust off a piece from 10 feet up, where your robot can't reach. Take a look around at small, subtle clues that are hard to discern even for a high-resolution camera with high-bandwidth data channels, but are trivially easy for trained eyes and wetware to see.
Costs more - of course it does. BUT robots and telepresence can absolutely NOT provide everything a human can do, except in pipe dreams...
