A lot of nice Io images are now up on the LORRI raw images page. I think this may wrap up the Io images except for some eclipse observations.
http://pluto.jhuapl.edu/soc/data/jupiter/l...0x630_sci_1.jpg This image shows Loki and Ra Patera at high phase angles. Note their forward scattering properties. At Loki, this is likely due to a glassy lava surface. Compare with this Galileo image: http://pirlwww.lpl.arizona.edu/~perry/io_i...2ISLOKI__01.jpg . See also http://pluto.jhuapl.edu/soc/data/jupiter/l...0x630_sci_1.jpg for a VERY shiny Loki. http://pluto.jhuapl.edu/soc/data/jupiter/l...0x630_sci_1.jpg Europa and Io http://pluto.jhuapl.edu/soc/data/jupiter/l...0x630_sci_1.jpg Is Thor erupting too? -------------------- &@^^!% Jim!

Whoah -- that glassy surface is really cool. I hadn't been aware of that charateristic of Ionian paterae before. Thanks for pointing that out, VP!

This appears to be all she wrote WRT Io images from New Horizons (LORRI images anyway), though there are some eclipse observations left to go. I want to congratulate John Spencer, Jeff Moore, Alan Stern, and the rest of the New Horizons team on planning and returning such a wonderful dataset, and I want to thank them for making these jpegs available on the web. Looks like there is plenty to work with, particularly with plume dynamics. I certainly echo John's statements at the press conference, that it will be sad to no longer see new images show up.
The final version of time-lapse movie from New Horizons can once again be found: http://pirlwww.lpl.arizona.edu/~perry/Io_movie.gif Here are a few looks at the images that showed up today: Here is the Io/Europa conjunction, with combined MVIC and LORRI data: And it does look like the Thor plume was active during the New Horizons encounter, with a much smaller plume than was seen and flown through by Galileo: -------------------- &@^^!% Jim!

Wow... the time-lapse movie leaves me speechless. Truly. Awesome.

Ditto. Thanks to Alan and the NH team for taking us along for the ride. And thanks to VP for volunteering to be and doing a great job as the UMSF Io Tour Guide. |

If you have been following the main Jupiter encounter thread, you know that some of the New Horizons data has been uploaded to the PDS. This includes data from all instruments, not just LORRI. For Io surface science, the most important instruments are LORRI, MVIC, and LEISA. I have made some headway playing around with LORRI and MVIC data. LEISA, well, the data is there, but the time being it is beyond my skills to manipulate. I can view but I have no method for trying to pull out hotspots from that stuff (other than Tvashtar, which glows like a beacon, that volcano sure is a ham... ). Anyway, here are the two color views I have been most looking forward to, and I will leave it at that.
For the record, the color data is from MVIC, with LORRI providing the greyscale high resolution data: The left image is from Ishine1 and shows a portion of Io's Jupiter-facing hemisphere illuminated by Jupiter. The MVIC filters used are blue (for blue), red (for green), and NIR (for red). The right image is from Initemon2 and shows Pele in color. The MVIC filter used are blue (for blue), 50% blue-50% methane band (for green), and the methane band. -------------------- &@^^!% Jim! I'm a geologist, not a physicist!

You've got to warn people before posting pictures like that

THANK YOU for that second Io pic... that is simply stunning... serious case of acne that poor moon has... Hope you won't mind me showing that pic in one of my school talks next week, the kids'll love it! -------------------- |

A few comments:
1) in the first image, Emakong Patera is a little further to the north, directly between Prometheus and Sigurd. The feature you labeled as "Ekhi Patera" is actually Arusha Patera. Ekhi is to the northeast. 2) The feature you labeled as "Amirani" in the second image is actually Shango Patera and the new lava flow that has formed to the south of that volcano. The feature you labeled as "Maui" is actually Amirani. Itzamna Patera is also labeled incorrectly. It is labeled correctly in the first image. -------------------- &@^^!% Jim!

He (3488) did. For some reason he wanted to delete all his posts and leave.
