Rosaly Lopes has a new blog post on the Planetary Society blog on the mysteries still surrounding Everyone's Favorite Moon (and if it isn't your favorite moon, then may a giant, falling chunk of komatiite greet you ). She aludes to the upcoming observations by New Horizons to study surface changes and volcanic activity on Io, and to an upcoming book, on Io. The book, Io After Galileo, is currently on Amazon, but rest assured, it will be available until early 2007. here is a link to the book's Amazon.com page: http://www.amazon.com/Galileo-Springer-Pra...TF8&s=books -------------------- &@^^!% Jim!

The utter mystery of Io certainly is mind-boggling, and this satellite definitely makes my top 10. Had to chuckle at Stevo's anecdote about "pizza-face" Io
Paul Schenk and others have written about the "surprisingly low relief" of the regions surrounding the hot spots. Paul noted that unlike Mars with its great shield volcanos, Ra Patera, the largest shield volcano on Io, was only 1 km high and its slope was <0.5 deg. Looking at the images that have become available (huge thanks to the imaging teams for providing them and to the community of amateurs and professionals alike for producing a variety of enhanced versions), it just seems to me that the regions near the active hot spots are shaped like lakes. So the question is: "What is the evidence by which we know that the flowing material (whatever it is) is flowing away from and not toward the active regions? martin |

While we are on this topic, there is a great new release on the photojournal.
