Today marks the 30th anniversary of Voyager 1's flyby of Jupiter. On March 5, 1979, Voyager 1 flew through the Jupiter system providing a wealth of information of Jupiter, its magnetic field, and moons. Thanks to Voyager 1, the Galilean satellites became worlds with real geology and amazing vistas. Voyager 1 also revealed Jupiter's ring system and Io's volcanism for the first time.
I've written up a longer post about the encounter with Io on my blog, which also has an animation of the flyby: http://gishbar.blogspot.com/2009/03/30th-a...1-flyby-of.html -------------------- &@^^!% Jim! I'm a geologist, not a physicist!

This is certainly extremely interesting. I tried recomputing the color balance of a Voyager 2 GRS mosaic I did back in 2001 ago but I now used calculations similar to those used above by Gordan and described in more detail in the VIMS thread. I think the color is significantly more realistic in the new version but beware that there might still be some bugs in my code so this might change slightly. Anyway, this is what it now looks like:
A smaller image showing the color in the old version of the mosaic: The new version definitely looks more realistic in my opinion. It should be noted that I haven't done any gamma corrections. By the way these are images of the Great Red Spot obtained by Voyager 2 on 6 July 1979 at a range of 3.8 million km. We are viewing the GRS from directly above in this mosaic so it shows the GRS' true shape better than the original images which were obtained with the spacecraft about 5 degrees north of the equatorial plane. |
