Probes Could Swim Through Ice on Mars or Europa
Fraser Cain writes "NASA's Institute for Advanced Concepts (NIAC) has funded a proposal to explore the idea of a robotic probe that could melt its way through the polar icecaps on Mars or ice covering Europa's ocean. A swarm of these these 100 kg probes would sample pockets of air in the ice as they maneuvered around in formation, searching for evidence of life - either past or present."
Before you bother to go to Europa, do try it at home! On Antarctica's lake Vostok. AFAIK, that ice above this lake is still not penetrated? Will it be easier on Europa, where the pH is around zero?
