Here's another goodie from my files. My first love has always been irregularly shaped worlds... I mean, my first among spacy things (sorry, dear!). This is Deimos in transit over Mars, from Viking. Not sure if this one has ever been published anywhere. It's from Orbiter 1, orbit 564.

I have seen that image before, but I think it was on your website! Do you know if the original is actually overexposed to the point of washing out? If not, it would be interesting to play with the grayscale.

Ted, it's so long since I did that, that I can't recall if Mars is saturated in the images (I think it's more than one image in that sequence). Probably not, I'd say, but Deimos is so dark that I just overbrightened it. I was really only interested in Deimos. But I bet you could get something better out of it.

 Here it is again : I published it inside "L'Astronomie Magazine" a few years ago. Deïmos was flying above Cassini Regio.Enjoy as desktop wallpaper to download !

Thanks Ted ! Ans as a tribute to PHIL STOOKE's great work on irregular bodies and for his nice discovery of the location of Viking Lander 2 on Mars, let's dedicate to him this Phobos image. It was flying above Ascraeus Mons enshrouded by morning clouds (also as desktop wallpaper for you to download). Enjoy !

Here is the raw black-and-white version of Phobos passing over that volcano from APOD:
http://antwrp.gsfc.nasa.gov/apod/ap031129.html Phobos Over Mars Credit: Viking Project, JPL NASA Explanation: Hurtling through space a mere 3,000 miles above the Martian surface, the diminutive moon Phobos (below and left of center) was imaged against the backdrop of a large shield volcano by the Viking 2 Orbiter in 1977. This dramatic picture looks down from the Orbiter's viewpoint about 8,000 miles above the volcano, Ascraeus Mons. Phobos itself is 5,000 miles below the Orbiter. North is toward the top with the Sun illuminating the scene from the South (black dots are reference marks). For scale, Ascraeus Mons is about 200 miles across at its base while asteroid sized Phobos is about 15 miles in diameter. In this spectacular moon-planet image, volcanic calderas (craters) are visible at the summit of Ascraeus Mons -- while impact craters on the sunlit side of Phobos' surface can also be seen! -------------------- "After having some business dealings with men, I am occasionally chagrined,
and feel as if I had done some wrong, and it is hard to forget the ugly circumstance. I see that such intercourse long continued would make one thoroughly prosaic, hard, and coarse. But the longest intercourse with Nature, though in her rudest moods, does not thus harden and make coarse. A hard, sensible man whom we liken to a rock is indeed much harder than a rock. From hard, coarse, insensible men with whom I have no sympathy, I go to commune with the rocks, whose hearts are comparatively soft." - Henry David Thoreau, November 15, 1853 |

For you to appreciate the picture processing, here is the REAL original pic taken by VO2. Enjoy (if I may say...)

It's part of a set of several images : this is why in my processings you see more on the left hand side of the picture.

I posted some views of Proteus I have been working on in the Neptune thread. Here are some improved versions. To the left is an image based on the only multispectral series Voyager 2 obtained. To the right is the 1.3 km/pixel image (resampled to 2.6 km/pixel to compensate for the underexposer. While there is some data loss with regards to the outline, it definitely makes a better looking picture this way. Color is based on the first view.
