Swarming for Extraterrestrials

Interesting idea out of NASA's Innovative Advanced Concepts (NIAC) - a robotics engineer has been awarded Phase II funding for miniaturized micro-swimmers that could be deployed through an ice probe beneath the ice surfaces of Europa or Enceladus. The swarm of swimming robots only inches in dimensions could explore ice-covered ocean worlds much faster than individual robotic missions when searching for signs of life.
