In honor of the 20th year anniversary of Huygen's landing. I have recreated the cloud texture from scratch using Cassini imagery to 16K and realign the south polar vortex to rotate correctly. I have also added a couple faint clouds to the northern areas as well as a hint of transparency much as what...

Major update to this addon EXPANDED RINGS!!! Saturn's outer rings are now displayed. Witness the majesty of the G and E rings!!! Turn up the brightness to reveal the Janus/Epimetheus ring and Pallene rings... turn it up to 11 and you may even catch the Anthe and Methone rings too! Watch these smalle...

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.

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 slig...

Grand Tour Mars has been updated. I have not updated this topic in a while.
The Grand Tour Mars can be found here

16K dust has been added. The planet will be found completely covered in a global dust storm if time is changed to dates like early June 2018 or October 1971. Otherwise it will have a few regional dust storms by default. This makes the planet change and come alive when viewing addons for missions lik...

Added local dust storms for when Mars isn't having a complete dust tantrum. Also added normal maps for both the non global clouds and dust storms. The global dust storm doesn't have a normal because its literally a global smooth sphere of dust with very little apparent shadow within. Arsia Spiral.pn...

PART 3 Eventually with the mapping of all available images, I then used layer mask to filter out where the closer images were lower resolution at the fringes. By luck, the Pioneer 10 closeup images worked well with Pioneer 11 images despite the planet's changing clouds with a band of squiggly clouds...

PART 2 With the images located and sorted, I started projecting them. Initially I used globes in closeup image documentation to map those, then I started mapping further out imagery. With each image, Jupiter's rotation revealed more and more of the planet. Images were prioritized by whichever were h...

PART 1 A month ago an idea popped into my head. I was unable to go to sleep so I decided to test it, mapping Jupiter as it appeared during Pioneer. This was going to be a challenge! Only a couple attempts have been done prior to map Pioneer images of Jupiter and they were low resolution 1K maps. I h...

A couple weeks ago I got the idea of making a Mars dust storm atmospheric layer. The problem is, objects cannot have more than one cloud layer. Thankfully there is a workaround for this. By creating an invisible non interactive diffuse object slightly larger than Mars, I can give it a cloud layer an...

(or well textures for comets if the base download of Celestia had them) Since prehistoric times, comets have been observed once in a while as wandering stars. What were they? Did they foretell grave omens? Much was to be asked of comets. It was in the 18th century Edmund Halley predicted the orbit o...

FULL ADDON HAS BEEN RELEASED!!! Added level 5-12 detail for landers. Added 43 extra overlays. Added night map. Added Pre Mariner 9 dust storm Mars texture to base download which displays all we knew of Mars from Mariner 4,6,7 and ground observations. Fixed texture issue around Opportunity. Added fai...

Updated to include albedo corrected Hellas, landing site details, and 16K clouds from real data. Now you can say goodbye to those inaccurate clouds and hello to high resolution ones from real data by MRO.

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. JupiterSL9.png Ganymede imagery was improved with a single image from Juno's SRU cam...

Part 4: With my base 64K map finished, I noticed the default Mars clouds are terrible. Even Origin and Echoes' clouds are terrible and don't look like realistic Mars clouds. I noticed the USGS had global mosaics of Martian weather from the MRO MARCI camera. Problem with these clouds is they move and...

Vesta.png Following the discovery of Ceres in 1801, a search began for more planets in the sky. After all, it was only decades earlier Uranus was discovered after millennia of there being six known planets. In 1802, Heinrich Wilhelm Matthias Olbers discovered Pallas, then there was Juno, Vesta, Ast...

Added several gigabytes of extra alternate textures like geology and topography:

The moon base has been updated with closeups of landing sites. Later this week I will have the geology, topography, mineral maps etc. uploaded as a separate download link as they are huge.

Mars, the fourth planet from the Sun and recognizable for its red color from Earth. Because of this color, it was often associated with the aspects of war and bloodshed. In the 19th century, telescopes had become advanced enough to observe any detail on Mars. It was noted that Mars had peculiar surf...
