Björn Jónsson produces beautiful color and 3D global mosaics of Vesta from Dawn's archival data.

Voyager 1 revisited: Io and Europa transiting Jupiter

Posted 2013/01/22 06:04 CST | 0 comments

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.

Pretty picture: Landsat view of southern Greenland

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.

This animation is composed of calibrated, archival science data. Cassini captured the 90 frames for this animation of the braided F ring at intervals of 3.5 minutes on February 13, 2013 from a distance of 650,000 kilometers.

Jupiter's cloud motions as Voyager 1 approaches

This movie is based on 58 orange-green-blue color composites obtained on every Jovian rotation from January 6 to January 29, 1979. Over this period Voyager 1's distance from Jupiter dropped from 58 to 36 million km, so the resolution and sharpness of the frames increases from start to finish. The 58 frames were tweened, increasing the number of frames by a factor of 8 (that is, 7 synthetic frames are inserted between each real frame).
