Thanks to the MRO the Viking Lander 1 site has been viewed twice already at nerly the same Mars local time :
- PSP_001521_2025_RED.jp2 taken on 11 November 2006 (w/30.3 cm/pixel resolution) at 3:20 PM ;
- PSP_001719_2025_RED.JP2 taken on 12 december 2006 (w/28.8 cm/pixel resolution) at 3:27 PM.

So I decided to pixel overlap the 2 pictures retrieved from the LPL site at their maximum resolution (as "full JPEG 2000" images), knowing that each individual pixel from those 2 images would not cover exactly the same area on Mars.
The goal was :
1. to gain some resolution over individual pictures ;
2. to assess the reality of some features as seen from orbit ;
3. to determine is some individual Lander components could be seen ;
4. to see an "average" site free from bad pixel and false features.

After a painstaking process, here are the results on the 4 goals :
1. resolution gained : ==> not obvious on overlap image ;
2. reality of some features : ==> real features are seen on overlap image ;
3. Lander components : ==> some individual components discriminated ;
4. "average" site free from bad pixel and false features ==> goal attained.

About the lander itself : the shadow seen for its high-gain antenna mast and for its antenna itself is narrow. This implies that the disk-shaped antenna was not facing the sun when the images were taken, meaning that the high-gain antenna is pointing either towards the north or towards the south.

The same overlap processings were also applied to the area where the backshell touched down the surface with its parachute ==> An overlap image is seen also.

About the landing site itself around Lander 1 with its features, please refer to the explanations given it the previous post :

...So I just merged the final RED hi-res panchromatic image (see hereabove) with the color product found on MRO's website !
Now you see the VL1 site in full color at its maximum resolution...
Enjoy !

This is a great image! Historic, even. I think the Viking 1 site is right up there with Apollo 11 as a place where we pushed forward as a race. Good work!

Thanks a lot JRehling for your kind comments !
...And here is the "basic" original color HiRise image from which the final color overlap (see hereabove) was produced (it has less resolution/pixel) and after final color calibration of course (deleting also the blue halo around VL1)...
Enjoy also !

Great!
I made this modified version in order to improve contrast/pixelization/color... (I do not know how much realistic is, however ).

Nice improvements, especially for pixellization !
Here is my final HiRise color processed image before I merged it with the hi-res panchromatic one...
Enjoy also !
