This map, which involved drawings and photos from telescopes, may be the last such map made for scientific purposes in the history of lunar exploration.

The map of "Luna Incognita," the sliver of the moon near the south pole missed by the missions of the 1960s and 70s, produced by the Association of Lunar and Planetary observers around 1990, which combined spacecraft and telescopic images. I was involved in the the final verification phase of it.

Small preview of color photographic map of Pluto in Mollweide oblique projection. It contains one large global map with four small hemispheric maps and basic description. Full version of this map is available for download in links in the main post.

Dione, moon of Saturn, from Voyager 1 on November 12, 1980. The wispy trailing hemisphere can be seen on the left-hand side.

Sorry, but we have pictures of the shooter, and he's a radical

In my hurry to share this before I got out the door this morning, I accidentally called this Mars in the original post.

Saturn from the Hubble Space Telescope in June of 2018. The color data used here extends from near UV to near IR, which is why the intensity of the features on the Saturnian disk seems more pronounced.

Actuellement deux comètes présentes dans notre système solaire semblent se tirer la bourre. Leur nom de code : C/2025 K1 ATLAS (à gauche) et C/2025 R2 SWAN (à droite). En réalité leurs trajectoires respectives sont très différentes.

Saturn, rings, and moons on August 30-31, 1979, from Pioneer 11 as it approached the planet. This was produced using images over a two and half hour period that spanned from just about midnight on August 30th into the wee hours of August 31.

Saturn from the approaching Pioneer 11. During this approach humanity saw the night side of the rings at an angle unachievable from earth (although the night side can be seen at times near a ring plane crossing, but the rings are much closer to edge on). Titan can be seen to the upper left, and a smattering of other moons made cameos.

The moon from the Galileo spacecraft during its flyby in December, 1992. The quality of the images it returned really shows what could have been had its antenna opened (it could send back images at a high rate with its omnidirectional antenna near earth, but not from Jupiter).

Europa from the Galileo spacecraft in June of 1997. The hemispheric differences in color are quite apparent when one compares the left and right sides of this image.

Je ne sais pas qui vous êtes, mais merci pour vos magnifiques photos et légendes. J'ai l'impression de voyager à travers la France.

Ted Stryk @tedstryk.bsky.social · Sep 14

Pioneer Venus too, if someone would put it on the web.

Ted Stryk @tedstryk.bsky.social · Sep 14

Yeah, but I'm just thinking of pretty global pictures right now. The lack of coverage of the Venusian surface is painful.

Ted Stryk @tedstryk.bsky.social · Sep 14

When I see all these new Mars images, I can't help but wonder what such a camera could show us at other worlds. We have great coverage of earth and Mars, plentiful UV coverage of Venus (though no active orbiter now). What would we see at Triton, moon of Neptune?
