Cassini imaging science subsystem (ISS) team associate Mike Evans speaks with Cassini NASA Social attendees, Thursday, Sept. 14, 2017 at NASA's Jet Propulsion Laboratory in Pasadena, California. Since its arrival in 2004, the Cassini-Huygens mission has been a discovery machine, revolutionizing our knowledge of the Saturn system and captivating us with data and images never before obtained with such detail and clarity. On Sept. 15, 2017, operators will deliberately plunge the spacecraft into Saturn, as Cassini gathered science until the end.

NASA Administrator Jim Bridenstine answers a question during a Mars 2020 NASA Social at Kennedy Space Center’s News Center in Florida on July 29, 2020. At left is NASA astronaut Zena Cardman. The Mars Perseverance rover and Ingenuity helicopter are scheduled to launch July 30, on a United Launch Alliance Atlas V 541 rocket from Space Launch Complex 41 at nearby Cape Canaveral Air Force Station. The rover is part of NASA’s Mars Exploration Program, a long-term effort of robotic exploration of the Red Planet. The rover will search for habitable conditions in the ancient past and signs of past microbial life on Mars. The Launch Services Program at Kennedy is responsible for launch management.
