Ge 194 Juno and Cassini. 6 units (3-0-3), first term. Prerequisite Ge103 or equivalent. A coverage of the key science addressed by Juno (currently in orbit around Jupiter) and Cassini (end-of-mission part only, close in to Saturn). Topics include the internal structures (gravity and magnetic field), atmospheric structures, composition and dynamics. The emphasis will be on how the spacecraft instruments work, what they measure and how the resulting data are interpreted. Outside speakers will be used on occasion. The big questions (origin of these planets) will also be addressed. Each student will do a small project related to the data or their interpretation. Instructors: Stevenson and Ingersoll.
