Sunday was the 10th Anniversary of Galileo's I24 encounter with Io. On the blog, I've been taking a look back at that encounter, first at the planning that went into the encounter and then yesterday I looked at some of the obstacles that Galileo scientists and engineers faced during that encounter:
Galileo's I24 Flyby of Io - A Look Back: Planning Galileo's I24 Flyby of Io - A Look Back: The Encounter Later this week, I will take a look at some of the data returned from that encounter and how it changed our understanding of Io. -------------------- &@^^!% Jim!

Finished up that retrospective on the I24 flyby with an animation of the encounter mixed with the data acquired plus a look at some of the result from the flyby:

Well just as I was headed to bed last night, I ran a quick search for papers on Io across all of Elsevier's journals, usually I just following papers posted in Icarus or Planetary and Space Sciences. I came across a paper to be published in the October 30 issue of the Journal of Volcanology and Geothermal Research called, "Volcanic history, geologic analysis and map of the Prometheus Patera region on Io" by Giovanni Leone et al. I read the article this afternoon, and after putting together a nice animated gif of high resolution Galileo NIMS and SSI data of this volcanic flow field, I've gone ahead and posted a summary of the paper on Gish Bar Times.
Enjoy! Geologic Mapping of the volcano Prometheus -------------------- &@^^!% Jim! I'm a geologist, not a physicist!

Sorry I've been ignoring the blog for last few weeks. Blame Modern Warfare 2, no free time outside that and work
Anyways, I've written up a post on another geologic map of Io, this time covering the Hi'iaka and Shamshu regions of Io: http://gishbar.blogspot.com/2009/12/paper-...-of-hiiaka.html -------------------- &@^^!% Jim! I'm a geologist, not a physicist!

With the 400th Anniversary of the discovery of Io and the other Galilean satellites coming up on Thursday, this week I am doing a series of posts on Galileo's discovery, Simon Marius's claim, and the discovery of the moons in the history of astronomy:
Io@400: The 400th Anniversary of Galileo's Discovery of the Galilean Moons Overview post for the Series http://gishbar.blogspot.com/2010/01/400th-...-discovery.html Io@400 Part 1: Copernicus, Galileo, and the Telescope The state of astronomy at the start of the 17th Century, the invention of the telescope, and Galileo's early innovations with it http://gishbar.blogspot.com/2010/01/io400-...alileo-and.html Io@400 Part 2: Looking through the telescope in 1609 Galileo and Thomas Harriot's observations of the Moon and nebulae in 1609 http://gishbar.blogspot.com/2010/01/io400-...-telescope.html Over the next three days, I will update my blog with three more posts, including a post on Simon Marius's claim tomorrow, the discovery of the Galilean satellites by Galileo on Thursday, and Galileo's Sidereus Nuncius and its effect on the scientific community in 1610 on Friday. Happy Io Discovery Day! -------------------- &@^^!% Jim! I'm a geologist, not a physicist!

Thanks again, Jason, for those great summaries of the work of Galileo and his contemporaries.
A question that interests me is when the Laplace resonance (the 4:2:1 ratio of the orbital periods of Ganymede, Europa, and Io) was first noticed and what people made of it at the time. Laplace explained the resonance much later, in the 1700s. You would think the resonance would have been noticed very early, given the great interest in the Galilean satellites at the time, especially their importance for navigation. You would also expect a lot of speculation on the meaning of the resonance once it was noticed. But I haven't heard any discussion of this. John |

John that would have been a good question at the conference last week, as there was a fair body of historical experts there . . . -------------------- Dr. Paul Schenk, Lunar and Planetary Institute, Houston TX

The Gish Bar Times is nearing its 2-year anniversary on Thursday, and with that I want to announce a new URL for the blog: http://www.gishbartimes.org . The old blogspot url will still work, so you don't have to change you bookmarks if you don't want to.
For those who are not regular visitors, lately I have been looking at some of the Io-related LPSC abstracts, including one of the stability of Ionian patera wall slopes and modeling of Pele's plume, examined the geology of Chaac Patera, the possibility of an induced magnetic field on Io, and an animation of the four Io flybys in the current Jupiter Europa Orbiter's baseline tour. -------------------- &@^^!% Jim!

REALLY spectacular animation, Jason!

I've started a new series on my blog where I profile one of Io's volcanoes each week, like I've previously done on a one-off basis for Reiden, Chaac, and Gish Bar.
The first volcano I am profiling is Pillan Patera, a volcano responsible for the massive dark spot seen in the reprocessed image ugordan posted earlier today. The first part is located at http://www.gishbartimes.org/2010/07/volcan...n-part-one.html . I had to break it up because I want to head to Best Buy in a few minutes to get Starcraft II, but I swear, I will get the rest of it in Part Two out tomorrow. I swear I will be productive tomorrow... -------------------- &@^^!% Jim! I'm a geologist, not a physicist!

Part two of my series on Pillan was posted yesterday, and I just finished up on Part Three.
I'm picking an easier to discuss volcano next week, Zal Patera... -------------------- &@^^!% Jim! I'm a geologist, not a physicist!
