A good panorama for Viking 2 is hard to find. I have gone through the online CR-ROMs at PDS and extracted everything useful, and combined it here in one panoramic image.

For each camera I took morning and afternoon pans, and for camera 1 also a noon pan. Then, for each camera, I made a composite of the multiple views, with flaws or gaps in one fixed from one of the others. The tricky part after that was to combine Camera 1 and Camera 2. My intention is to mimimize obstructions by spacecraft components and maximize the visible surface, plus to combine the two views of the foreground into a full view of the sampling area. This cannot be done without introducing distortion in this view. Later I will rubbersheet the image to fit proper ground control for a photomap of the sampling field.

Everytime I look at the Viking sites I still marvel at how lucky we were. Beautiful work as always, Phil.

Quick question: How did you account for V2's site slope in this view? IIRC the lander had something like an 8-deg tilt, so would have expected a very shallow parabola across the top of the FOV. Was this sort of "washed out" by the distant topography in your rendering?

Just curious, and forgive me if it's a silly question; my abject lack of image processing skills matches my lack of understanding of them!

The tilt was already corrected for in the assembled panoramas I worked from. They were made at JPL and saved in a rather chaotic collection of archived files in the PDS. The hard part was finding suitable files to use.

Right now I'm trying to project the pan onto a HiRISE image to make a photomap.

Gorgeous pic Phil, great work as usual. I could - and probably will! - stare at that for yonks! smile.gif

Here's the Viking 2 pan wrapped into a circle with exaggerated horizon relief - greatly exaggerated, or you don't see anything. I did this for Viking 1 a while ago.

Thanks! I am doing some improvements to the panorama to get more uniform lighting - I just used the contemporary mosaics, now I'm making my own camera 2 pan with better morning lighting. Meanwhile, also working on step by step arm activity illustrations similar to some posted earlier. I must have Viking 2 finished by the end of July to stay on track.

Unique scenary. Surface is very rocky. That leads me to think on how lucky was Viking with landing!

Those were AWESOME, VM, thanks!!!

Never, ever saw that V1 pan before; the arm was a beast indeed!

Spectaculars pictures. The VL2 landing is terrific. How lucky was VL2. Thanks Vikingmars.

Speaking of Viking... next week I'm at Brown University, going through the papers of Tim Mutch in their archives. I'm looking for the minutes of the Viking Landing Site Working Group and related materials. Should be fun. smile.gif
