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."
