On May 8, 2012, Bill Nye and Neil deGrasse Tyson brought their unique brand of motivational speaking to Capitol Hill. In a standing-room-only lunch discussion in one of the meeting rooms for the Committee on Space, Science, Technology, these two space superstars, along with planetary scientist Louise Prockter, explained to members of Congress, staffers, and media why we must continue to invest in planetary exploration.

Welcome to my monthly roundup of the activities of our intrepid robotic emissaries across the solar system! I count 16 spacecraft that are actively performing 13 scientific missions at Mercury, Venus, the Moon, Mars, Vesta, Saturn, and at the edge of the heliosphere. This month's highlight: Cassini's about to fly close past Enceladus and Dione.

Welcome to the Planetary Society's new website! What you're looking at right now is the result of months of continuous effort by the very small Web team here at the Society. Our goal was to create a new home for the Planetary Society on the Internet that reflects the way things have changed since our last redesign: changes in the Planetary Society, changes in space exploration, and changes in the way the Internet functions.
