Riverside, Calif (ucr.edu): On Thursday, May 10, NASA Astronomer Trina L. Ray will give a presentation at UC Riverside, “Cassini’s Legacy: Saturn’s Secrets Revealed.”

Ray will highlight the most exciting discoveries of NASA’s 20-year mission to Saturn, which ended with the Grand Finale on September 15, 2017. The talk will provide an overview of the questions the Cassini mission has answered (and will continue to generate) about the planet Saturn, its magnetosphere and spectacular rings, and Titan and the other icy moons.

The international Cassini-Huygens spacecraft was launched on October 15, 1997 and entered orbit around Saturn on June 30, 2004. The 23-foot tall, 14-foot wide, 6-ton spacecraft was the largest most sophisticated outer planet spacecraft ever built. Its key discoveries included liquid methane seas on Titan, and the global ocean with indications of hydrothermal activity within the moon Enceladus. Even in its last moments Cassini added to the massive amount of data it had collected.

This program is cosponsored by UCR Library and the Librarians Association of the University of California - Riverside Division (LAUC-R).
