Björn Jónsson (Iceland) is the developer of the IMG2PNG software, which batch-converts spacecraft image data to PNG format. His website contains simulated views of other planets produced using image maps generated from space image data; most of his image processing work is posted only within unmannespaceflight.com or on this website.

What is the highest resolution global Jupiter mosaic that includes a satellite transit that can be assembled from Voyager images? Satellite transits are especially beautiful when the resolution is high enough for some details to be visible on the satellites so I decided to check this. And I was remarkably lucky.

This is a very large (19000 pixels square) mosaic of the fjords and glaciers of southern Greenland. I had been interested for a long time in experimenting with the processing of Earth satellite imagery just to get a comparison to the other planets.

Back in 1979 the twin Voyager 1 and 2 spacecraft flew by Jupiter. Some of their images were processed into color images and mosaics that have appeared countless times in books, magazines, on TV and on the Internet. Many of these images and mosaics are spectacular but they were processed more than 30 years ago using computers that are extremely primitive by today's standards. It's possible to get better results by processing the original, raw images from the Voyagers using modern computers and software.

An animation assembled from 58 images obtained by the Voyager 1 spacecraft from January 6 to January 29, 1979. The animation has been 'tweened' to increase the apparent number of images and the smoothness of the cloud motions. Jupiter's size is held constant even though the spacecraft's distance dropped from 58 to 36 million km from start to finish of the animation. The individual images were obtained one Jovian rotation (10 hours) apart and have been sharpened a bit to reveal more details.

A double transit of Jupiter by moons Io and Europa, as observed by Voyager 1 on its approach on February 27, 1979. This is a 14-frame mosaic. Most of the data was captured in a 3-by-3 mosaic at around 11:00 on February 27, 1979, but gaps were filled with data taken an hour before and an hour later.
