  • NASA’s plans to explore the ice moons of the Solar System are getting more detail as the space agency is developing a robot that would use steam to power itself in deep space.
  • In a post to its website, NASA’s Jet Propulsion Laboratory notes researchers are developing a soccer-ball sized robot known as SPARROW (Steam Propelled Autonomous Retrieval Robot for Ocean Worlds) that “would use steam propulsion to hop across the sort of icy terrains found on Jupiter’s moon Europa and Saturn’s moon Enceladus.”
  • By using steam to power the robot, SPARROW could thrive in the “low-gravity environment” on Enceladus and Europa, hopping “many miles over landscapes that other robots would have difficulty navigating.
