JPL designed, developed and assembled the Cassini orbiter. Buratti led a team of 35 co-authors that published their work in the journal Science on March New findings have emerged about five tiny moons nestled in and near Saturn's rings. The work paints a picture of the competing processes shaping these mini-moons. The surfaces of the moons Atlas, Prometheus and Pandora, farther out from Saturn, have ring material as well - but they're also coated with the bright icy particles and water vapor from the plume spraying out of Enceladus. Scientists will use the new data to model scenarios and could apply the insights to small moons around other planets and possibly even to asteroids. Scientists also found the moon surfaces to be highly porous, further confirming that they were formed in multiple stages as ring material settled onto denser cores that might be remnants of a larger object that broke apart.
