Early this month I had trouble sleeping one night and this thought came into my head as I had been working on maps of Mars. "What if I try to make a map of Jupiter from Pioneer. Surely the available maps do not do justice to the lost world of Pioneer era Jupiter with its Red Spot floating amid a milky white band."
So I got to work hunting down images from this program. One person I tried to contact was Ted Stryk of fame on here but sadly I was unable to get in touch with him to see if he had further info on the images. The places I got images are: http://www.astrosurf.com/nunes/explor_p10_11.html https://www.planetary.org/space-images/post...yk_lpsc_pioneer https://web.archive.org/web/*/http://astros...xplor/pioneer/* Using ReprojectImage, I crudely reprojected the images, tinkering with the results until I got it. Biggest hurdle was the images were often deformed because of the slow speed Pioneer 10/11 took images relative to Jupiter's rotation and movement of spacecraft. I then moved the images so they are correctly located in relation to each other to my best ability given the planet's rotation and changing clouds. Then I changed the brightness and color until it matched something close to real color. This is the result after 70 hours. The highest possible resolution map of Jupiter from Pioneer imagery. (Yes I know the planet changed between P10 and P11 but oddly when I was putting this together, the clouds lined up pretty well with no changes to the bands between the two spacecraft.) It is a major improvement over existing maps and it even captures some of the polar areas and the swirl in the GRS. -------------------- "Thats no moon... IT'S A TRAP!"

Great work! I'm probably more struck by the details that, in your processing, come to look like familiar and timeless (?) features of some latitudes than the unusual quirks of the GRS and the mid-south. The Pioneer imagery of Jupiter will permanently be a significant early record in a finite and ongoing sequence of looks at that changing planet and useful to our understanding of what is normal, repeating and what is not. This work should help with that!
