Grand Tour Jupiter

Io with it's many volcanoes and mountains behind Jupiter's aurorae.

Jupiter is the definitive King of Planets in both size and color. It's surface is not so much a surface as much as it is the topmost layer of clouds that boil and swirl like a planet-sized witch's cauldron. It was known to the ancients but little did they know, had it not been for Jupiter's brightness, they would be able to see with just their eyes 4 dots around Jupiter. It was 1610 when Galileo pointed his telescope that he saw those four points of light around Jupiter. The discovery of these "moons" shattered the prevailing line of thought that everything orbited the Earth, almost landing Galileo in prison in the process. For centuries, these moons remained a mystery and it wasn't until 1892 that a fifth moon, Amalthea was discovered with further discoveries following. When Voyager 1 flew past Jupiter with more modern camera equipment, it discovered a solar system of Jupiter's own.

This overlay set overhauls 9 of the objects in the Jupiter System:
16K Jupiter from Juno and Cassini
8K Voyager Jupiter
4K Pioneer Jupiter
2K Jupiter night
16K Jupiter rings
1K Metis from imagery
1K Amalthea from imagery, not that shaded relief map everyone uses
1K Thebe from imagery
16K Io texture
4K Io specular (gives those lava lakes a slight reflectivity
4K Io night (NOTE:Night textures do not work when moons are eclipsed, it is a well known bug in Celestia)
16K Io normal (about 50 percent of it but it gives off nice shading detail)
64K Europa
64K Ganymede
64K Callisto
You can see the readme for where I got the hard to find albedo maps for the inner moons as well as the large Io dem, and 64K Europa and Ganymede.

Like father, like son, a crater on the largest moon serves as the foreground with the largest planet as the background.

Updated over the forum outage. Added date dependent layers for Jupiter. Now you can witness Jupiter as it appeared during Voyager or when SL9 impacted it. To see these, change the time to when these events happened.

Ganymede imagery was improved with a single image from Juno's SRU camera. Callisto was improved with small areas of extra detail from USGS maps.

This addon has been updated with a few things:
Inner moon colors have been corrected
Io Night has been tempered to look less like its undergoing nuclear fusion
Juno Data has been added to Europa and a better geologic map has been found
Juno added to Ganymede geologic map
Europa darkened ever so slightly so its not just a featureless white ball
Pioneer Era Jupiter has been developed with 4K resolution maximizing what was imaged by those two probes.
Placenames updated for Galileans.

Story of how Pioneer Jupiter was mapped can be found here: viewtopic.php?f=6&t=24484

Updates to come:
Possible redo of Amalthea to clean up seams
32K Io with Juno updates
JIRAM Io map
Io night redone in higher resolution
Io normal fix with Juno data
Jupiter by the year since Hubble

Some digging revealed there were pieces of a USGS map of Callisto that allowed 64K coverage of the moon. Finally some justice to Callisto!!! Color was made a bit more realistic and detailed. Galileo NIMS spectral maps added to it and Europa.

In 64K, isolated parts of Callisto imaged in high resolution by Galileo can now be viewed at max resolution
