If the goal of planetary exploration is to build a permanent and expanding, self-sustaining extraterrestrial civilization,
then clever and myriad uses must be made of planetary resources. Resources must be identified and evaluated
according to their practicality. A new economy should be devised based on resource occurrence, ore accessibility,
options for ore transport, material beneficiation, and manufacturing; end uses and demand; and full economic
cost/benefit assessment. Locating and evaluating these resources should be done with coordinated robotic assets
arrayed in orbit and on the surface. Sensor arrays and tandem on-ground means of physical manipulation of rocks
should incorporate highly capable onboard data processing, feature detection, and quantification of material
properties; intelligent decision making; a flexible capacity to re-order priorities and act on those priorities in carrying
out exploration programs; and human-robot interaction. As resource exploration moves into exploitation, sensors
working in tandem with robust physical manipulation will place increased emphasis on automation in effective and
safe robotic quarrying, tunneling, boring, and ore beneficiation. Any new global planetary economy will have to
weigh the efficiency of resource identification and utilization with full-spectrum cost/benefit assessment for human
health and safety, the environment, future habitability and sustainability, and human priorities in the development and
growth of civilization. It makes no sense to rove from one planet to another in a wave of resource use and depletion,
like interplanetary locusts. Robotic systems will open new worlds to human use, but they will also place a premium
on human ability to control exponentially growing consumption.
