This Week at NASA: Oceans Beyond Earth and More.

Two long-running NASA missions are providing new details about ocean bearing moons of Jupiter and Saturn - further heightening scientific interest in these and other "ocean worlds" in our solar system and beyond.

The details - discussed during an April 13 NASA science briefing - include the announcement by the Cassini mission that a key ingredient for life has been found in the ocean on Saturn's moon Enceladus. Meanwhile, researchers using the Hubble Space Telescope observed a probable plume erupting from the surface of Jupiter's moon Europa, at the same location where Hubble saw evidence of a plume in 2014. Researchers say this could be circumstantial evidence of water erupting from the moon's interior. Hubble's monitoring of plume activity on Europa and Cassini's long-term investigation of Enceladus are laying the groundwork for NASA's Europa Clipper mission, which is being planned for launch in the 2020s. Also, Expedition 50 Returns Home Safely, Next Space Station Crew at Launch Site, Student Launch Event, Groundbreaking for New Lab, and Yuri's Night, First Space Shuttle Mission Celebrated.
