The Cassini Mission has less than two months to go before it ends with a spectacular plunge into the beautiful ringed world. Planetary Society Senior Editor Emily Lakdawalla has prepared a guide to the last orbits by the historic spacecraft. Bill Nye provides examples from his new book of how we will benefit from space applications and the way nerds solve problems. His impressions may not be ready for prime time, but Bruce Betts’ guide to the night sky and Random Space Facts are always entertaining.
