Happy New Year !

In the beginning of 2016 I suggest you rediscover the Viking Lander 2 site in high resolution and color !

Here

NOON HIGH RESOLUTION COLOR MOSAIC :



This project failed well never produce : I really totally/completely underestimated the time needed !!!


EDIT

Viking Lander 2 Camera 1
21i091 HIGH RESOLUTION COLOR (Frost) :

I add links to all high-resolution color images :






There are also "old" cited in post # 61:

But quality is not perfect ...

Here's another one from Ricardo Nunes who also worked with Ted Stryk's super-resolution images as mentioned in post #5 of this thread.

Two other images of Ted Stryk :

Yes it's time -consuming. But your work is very nice indeed.
Thanks a lot Vanden to share it with us and congratulations !!!

Nice to see Vanden's persistence and new result with the VL2 noon color hi-res panorama!

Thanks !

I edited my post "NOON HIGH RESOLUTION COLOR MOSAIC" to add a new high resolution color image : 21i091_HIGH_RESOLUTION_COLOR

Although modest in size it is a part of the famous/historical/mythical low-resolution color image (official version): PIA00571

For information here's how raw images (mainly used) are :
- Low-resolution color: 21i093
- High-Resolution black & white : 21i091

My Low Resolution version (21i090+21i093+21d224-225-226) :

Viking Lander 2 Camera 2 Low Résolution FROST Color Images :

22i109 (Sol 1050 12:40

I used a low-resolution panorama of Oliver (thank) as a basis for color calibration.

Viking Lander 1 Camera 2 Low Résolution SKY AT SUNRISE

Thanks a lot Vanden for those good processings of yours ! How NICE they are ! Your 'frost' pan is gorgeous wheel.gif wheel.gif wheel.gif

The picture you show ('Low Resolution SKY AT SUNRISE') is a very interesting one indeed !
It is the 1st of three images taken more than ten minutes apart on Chryse Planitia by Viking Lander 1 on Sol 379 at 07:50 a.m, 08:03 a.m. and 08:15 a.m. respectively (see the 'triptych' herewith).
The fog had settled in over the entire area and it was dense enough so that the Sun was not visible above the horizon until the last image where it made a shy appearance (elevations respectively of 0.0°, 2.7° and 5.4°).
Like on Earth, sunrise on Mars often sees frost and patches of fog and low clouds made of water ice crystals.
These images were the first direct, visible evidence of water exchange (moisture) between the Martian surface and its atmosphere.
Sometimes, the cold nighttime temperatures lead to saturation of water vapor with fog formation that extends to altitudes of 60 m (97 feet) to 80 m (262 feet) above the surface during the night.
Usually, the fog disperses within two hours after sunrise. smile.gif

About your good idea of processing VL2's nice Sol 631 sunrise, here is the full story of this picture : the goal was then to capture the blue aureole of the Martian sky above the horizon.
So, the Viking Lander Imaging Team members programmed camera # 2 to avoid imaging the Sun itself and the risk of damaging the delicate sensors.
But, the timing of the sequence was calculated without enough margin. When the camera started to record the scene, the Sun was not yet visible.
But when the mirror scanned the place where the Sun had to be, this one had just popped up over the horizon !
This small inaccuracy resulted in the making of one of the most ‘iconic’ picture ever recorded by the Viking Landers : the first picture showing a sunrise on Mars.
Please, note that the banding in the sky is an artifact produced by the subtle brightness levels that cannot be accurately captured by the camera imaging scan system.
Also, some oblique delicate wispy markings in the sky crossing the aureole are thin cirrus clouds made of small water ice particles and believed to be drifting at an altitude of 10 to 15 km (6.20 to 9.30 miles) above the surface.
This picture was the very first to capture Martian clouds from the surface.
At the lower right of the picture, part of the Lander’s leg #3 support structure can be seen (herebelow here is my version)

Thank you for the information !

Small correction my Viking Lander 1 Camera 2 'Low Resolution SKY AT SUNRISE' 12E189 is the second of three images taken more than ten minutes apart on Chryse Planitia by Viking Lander 1 on Sol 379 at :
12E188 : 07:38
12E189 : 07:50
12E190 : 08:02
I have long wondered what is the white "spot" in the sky in 12e190 picture !!!
In all first I thought is noise (the sun is not visible 12 minutes earlier) but it's too big and too concentrated for make this possible.
I also thought the sun (see a star) but the sun should overexpose the sensor and should have been visible 12 minutes earlier ...
But thanks to your explanation, all become more understandable ! Thank you !

Also thank you for your version of the 22H093 picture (and the explanation), I am inspired me to correct my version (minimization of overexposure in the blue and green channel).
The link remains the same (see my previous post)

I made a nice flash animation that shows the different modes of the camera :
- Low Resolution Color (NOON SEVEN MULTISPECTRAL FILTER MOSAIC 22a190) @ 600%
- High Resolution Color (HIGH RESOLUTION COLOR 22b-089-100-103) @ 200%
- High Resolution Black and white (for luminance) and High Resolution Color (for color) (NOON MOSAIC 22b057.bb1) @ 200%

Here also the first frame of NOON MOSAIC 22b057.bb1 panorama with the color layer of (Native) HIGH RESOLUTION COLOR (Mosaic) panorama : 22b057HighColor @ 200%
I think the 2/3 (right) of NOON MOSAIC panorama is feasible with the same quality ... for the rest it will be much more complicated !

Hello,

I made a website to present my images: http://www.astrosurf.com/marsimages/VikingLander2.htm
There are also all raw panoramas of viking lander 2 camera 2: http://www.astrosurf.com/marsimages/VikingLander2RAW.htm
