The fissures seen here have lead NASA scientists to believe there may be "ocean-like" liquid salt water on Enceladus, one of the dozens of moons that circle Saturn. The fissures spray icy particles, water vapor, and organic compounds--erupting from beneath the surface and into the atmosphere, NASA said today. The cosmic dust analyzer aboard NASA's Cassini spacecraft found particles low in salt far away from the moon, but samples from closer to Enceladus' surface found that large grains rich with sodium and potassium dominate the plumes, suggesting a composition beneath the surface that's similar to Earth's oceans, according to Frank Postberg, a Cassini team scientist at the University of Heidelberg in Germany.

Is this a real RoboCop?
The K5 robot, developed by Sunnyvale, Calif.-based Knightscope, is designed to be a surveillance robot for law enforcement, private security firms, schools and anything else looking for an extra set of eyes and ears on the ground. The 5-foot, 300-pound robot can roam autonomously, sending back real time data about an area with technology that does facial recognition, lidar mapping and 360-degree video. CNET's Kara Tsuboi got a closer look at what makes the K5 robot tick.
