In the past we've had some good Viking images here. Soon - all too soon - we will not have Phoenix any more, but despair not! Now we can re-live Viking by playing with old images. They can be searched by sol at the PDS.
As an example, I've made a composite of the very last Surface Sampler activities at either Viking site. This is work done on Viking 2 sol 957 and imaged on sol 957 and 959. (someone can animate it if they like!)
We see two separate trenching activities at the same place, and a soil dump (bottom) and a conical soil pile made by the second dump (middle). (more obvious in an animation, I just can't make one on this machine).
Phil
Attempt at an animation - not terribly good I'm afraid, I'm a clumsy beginner at this image processing lark.
Great idea Phil... that will bring back some childhood memories.
1976 was a great year for a 10-year old
This is a set of four images documenting that last sampler activity. It is labelled with sol dates. The first trench was dug more than a year before the final digging event.
(EDIT: I have replaced the previous image with a corrected one, and fixed the text describing it)
This last digging event came so late in the mission that it is not documented in the trench maps published by Hank Moore et al. If anyone knows a final trench map that includes it I'd be pleased to know about it. Otherwise I will be making one myself in due course. Note - images 2 and 3 show no surface difference, just different lighting.
I will assemble other surface activity sequences like this, and I'd like to encourage others to join me.
Phil
Ricardo Nunes and I worked together on some images. I made the grayscale images and he did he color.
You can see them on his site under the "super resolution RGB" tab. You can also see his work under other tabs.

Here's a bit more Virtual Viking - reliving the Viking missions to make up for the impending loss of Phoenix.
This is a comparison of the Viking 1 sample field - right side - seen before the arm operations began and after they ended. There are lots of changes - trenches dug, rocks moved, soil piles constructed (one at far left is on top of a rock).
Phil
... and here's the left side of the Viking 1 workspace, before and after.
Phil
Thanks Phil these are quite nice....
I have just edited post 4 above - and replaced its image with a corrected version.
Here is the Viking 2 before and after trench image - right side of the workspace. Lots of frost spots in the lower image.
Phil
Here's another digging sequence from Viking 2. First, a view before anything happens. Then two views on sol 471, before and after a rock called Snow White was moved. The before image (left) also shows a disturbance just below the sampler arm, suggesting an arm touchdown on the surface some time between sols 454 and 471 (possibly on sol 471 just before the image was taken - but I can't find any documentation of it). The last image shows that the dark scrape made on sol 471 as the arm was retracted has been enlarged. This was the XRFS sample no. 12, but it failed to collect a proper sample.
Phil
Nice work, reading " A Passion for Mars " by Andrew Chaikin made me dug up some old treasures
Here's a pic from Viking:
Wow...I don't think I have ever seen those together.
The goldmine(s) for Viking Lander images:
Lander Picture Catalogs of Experiment Data Record - NASA Reference Publication 1068
Does one need a password to access the Planetary Data System ( PDS ) ?
http://pds.jpl.nasa.gov/
No.

http://pds-geosciences.wustl.edu/geo/vl1_vl2-m-lcs-2-edr-v1/vl_0001/browse/
I prefer this source, from which images can be selected by sol, or by clicking on mosaics for each camera to select pictures of a given area.
http://pds-imaging.jpl.nasa.gov/vikingl/vl_images.html
Phil
The Viking 1 site mapped in a new way... This is the polar projection of the landing site, which I posted some time ago, reprojected to HiRISE geometry. In this comparison, HiRISE is at the top and the reprojected Viking pan is below it. Mapping from ground-level images is very difficult, and grotesque distortions are inevitable, but this is the best I can do after several weeks and far too many iterations. The original is detailed enough to make a full photomap of the sampling area, and in that area the mosaic is controlled to fit the original mission map.
Phil
I'm still perfecting that reprojected Viking 1 site map. Meanwhile here's a composite of images showing surface changes at the Viking 1 site. There were a few changes in soil patches on the lander itself as well, otherwise these were the only changes seen by Viking 1. For the first one, of course, the change I'm drawing attention to is the erosion by wind of Conical Pile 4 late in the mission. Several other artificial piles of soil were made and monitored but didn't change.
Phil
Another of the things we can do so much better now than in the old days...
The Vikings carried mirrors on the sampler arm, and one of them could be viewed by one of the cameras to see underneath the lander. Seven images of the mirror were taken by Viking 1 on sols 528, 550, 582 and 594. They can be combined to produce a mosaic of the area underneath Engine 2 (the one right under the cameras) to look at the erosion effects of the engine during landing. The version made during Viking times was really bad! But now we can do it much better. This image contains two separate mosaics - they are supposed to fit together, but right now I don't have the old mosaic with me to compare and figure it out. They have been reversed to take the reflection into account and enlarged 2x. The bottom mosaic shows an erosion pit where loose soil has been blown away to reveal harder crusty stuff underneath. (EDIT: I found the location and fixed the mosaic)
Phil
Here's the Viking 2 mosaic underneath Engine 2. The images were taken on sols 57 and 555.
Phil
Those are truly special, Phil!
They are indeed! I'm gonna start saving my pennies for your forthcoming atlas...
I have edited my post above with the Viking 1 mirror mosaic - took out the old attachment and replaced it with one showing the two halves joined correctly. I found one 'accidental' mirror image from Viking 2 as well, that adds to coverage there, but I don't know exactly where the new frame fits. It doesn't actually overlap the mosaic. For reference these mirror mosaics cover an area roughly 20 by 60 cm across.
Phil
Another bit of Viking history now we are all thinking about the amazing views out past Endeavour crater in the Opportunity thread. After the Viking landing sites had been chosen in 1973 people began to have concerns about their safety. They looked for some extra-safe sites (as determined from earth-based radar) near the equator, the so-called C sites (A sites were at 20 north for the first mission, B sites at 44 north for the second mission. C would be used if A crashed or if all sites at those latitudes looked too rough in Viking images). C1 was just north of Capri Chasma, C3 at Schiaparelli crater, but C2 was at Meridiani. Here's a map showing three possible ellipses described in the minutes of the Landing Site Staff during Viking site certification in 1976. The top one just touched Endeavour crater.
Phil
Fascinating (not a word I use lightly), Phil; did not know that.
One can only imagine how the Mars exploration strategy might have evolved had V1 landed in Meridiani on top of a nice piece of sedimentary pavement...
There's a lot of good stuff in those committee minutes. My next step is to go through the Viking landing Site Working Group minutes from c. 1970-1974.
Phil
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.
Phil
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.
Phil
Gorgeous pic Phil, great work as usual. I could - and probably will! - stare at that for yonks!
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.
Phil
Awesome job on both.
Amazing!
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.
Phil
Unique scenary. Surface is very rocky. That leads me to think on how lucky was Viking with landing!
As a tribute to Phil's gorgeous work, here is a VL2 controlled mosaic made in 2001 for a Mars educational exhibit built for the French section of the Mars Society... Enjoy !
...and now for VL1 (especially made to show to the public the technical aspects of the robotic arm/soil sampler). Enjoy also !
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.
Merci Olivier... the quality of the panos is absolutely stuning
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.
Phil
Ooo...gotta be some good stuff in there, Phil, happy hunting!
Admit that I'm most curious to know just how close they came to selecting Meridiani as the V1 landing site.
OK, back from Providence with lots of goodies.
Nprev - they didn't get close to choosing site C2 - Meridiani. They had three sites at that latitude, Capri, Meridiani and Schiaparelli (C1, C2, C3), but they never considered any but C1 seriously.
C1 was called Capri, but it was not in Capri Chasma, part of Valles Marineris. It was on the plateau north of the canyon. A similar site was considered for Mars '84, an ambitious rover mission.
Phil
Welcome back, and thanks for checking that out, Phil!
So, when's the book coming out? Gotta admit that the hindsight gained from everything since Viking makes the project's history even more fascinating. 'There were giants in those days!'
My current plan is to submit the manuscript at the end of 2011, for publication a year later. That would be for Volume 1, up to Mars Express. Volume 2 would follow about 3 years later. But a final decision on a 1 or 2 volume format has not been made yet, and if it's a single large volume it will take 5-6 years.
Phil
Here's a little goodie from my visit to Brown University earlier this summer (and big thanks to everybody there for the help, both in the archives in the John Hay Library and in the RPIF).
This map shows the first serious effort to pick landing sites for Viking. If you read the NASA history volume 'On Mars', by Ezell and Ezell, those authors mention a meeting late in 1970 when the members of the Viking Landing Site Working Group proposed 'several lists of sites, including six by Carl Sagan'. But Ezell and Ezell don't identify the sites. I hoped to find the committee minutes, among Tim Mutch's papers in the archives. I did get to see his papers, but mostly material on Mars 1984 (a rover mission) plus some interesting personal things about his Himalayan expeditions before the one he died on.
But in the RPIF I found - or rather Peter Nievert found for me - a real gem. Ezell and Ezell had written a much more complete account of the site selection process, in a hand-annotated typescript. It must have been condensed for the later history volume, but this version had all the missing bits in it - very nice indeed. So here is a map of those sites, chosen when the only spacecraft data were from Mariners 4, 6 and 7 (so plotted on a Mariner basemap).
Phil
"High speed" panorama from Viking 1. Its low-res, not so good as from vikingmars (really awesome job!).
But its all around panorama.
Morning on Mars from Viking 2 lander. First image was transferred to Earth without middle part.
...and the same for camera 2.
scalbers, Machi - just fantastic work, guys, genuinely thrilling to see those images. I wonder what amazing sights we'd enjoy if we - and by "we" I obviously mean geniuses like you! - went back through the all Viking data and used modern image processing techniques on the lesser-known images...
Stu - one "modern" thing I've long been interested in would be to combine low-res color information with the hi-res mosaic intensities. This might look pretty good if the lighting were close enough in each.
Steve
All these ideas are very good - and exactly what I was hoping to encourage when I started this thread. I'll dig out some more of my stuff too...
Phil
Yes I can appreciate the hi-res color mosaics might be challenging, yet I believe the effort may be worthwhile. The hi-res is three times the angular resolution of the low-res so there is a significant gain in detail (9 times the pixels). I recall back in 1977 that this type of combining was done at least in the context of individual hi-res images and it looked pretty good. It was done at JPL/IPL using VICAR so any geometric corrections would have been doable (e.g. with the GEOCAM program).
I wonder if the original imagery can still be reprocessed with http://www-mipl.jpl.nasa.gov/external/vicar.html somehow. Otherwise something like IDL or other languages can fairly easily correct for camera tilt. The other camera distortions might require something like what VICAR/GEOCAM did if they are significant. If there are offsets in shadows then maybe a fancier program can be put together that would use "nearby" color information when needed.
Looking online, here are some http://nssdc.gsfc.nasa.gov/photo_gallery/photogallery-mars.html#surface from Mary A. Dale-Bannister.
Here's http://www.astrosurf.com/nunes/explor/viking/12d089cal.jpg from http://www.astrosurf.com/nunes/explor/explor_vik.htm who also worked with Ted Stryk's super-resolution images as mentioned in post #5 of this thread.
The black and white mosaics do have fairly consistent lighting, so I'm checking whether there are any wide angle panoramic color images (or mosaics) from similar times of day where this can be attempted. Using Phil's PDS link in post #19 I was able to construct this fairly wide angle low-res color view. I can see the lighting and geometry issues when matching to the hi-res mosaic. The missing vertical lines need to be filled in as well - there used to be a VICAR program called FILLVL to do this.
Can anyone help me with this? I'm trying to find out how many images were taken by Viking Orbiter 1 and how many by Viking Orbiter 2. All I can find is the combined value.
Phil
Sorting the CUMINDEX.TAB file for Viking Orbiter on SPACECRAFT_NAME, I get
34918 VIKING_ORBITER_1
15582 VIKING_ORBITER_2
Does this sound reasonable?
That was quick! Thanks very much. Yes, very reasonable because VO1 lasted twice as long as VO2.
Phil
Just to follow up, that number may not include some approach views, calibration images, satellite and ring search images etc. (Yes, there was a satellite and ring search at some point fairly late in the mission) - but it seems to match the archived image totals - as of course the source would suggest it should. I have a suggestion that 1039 images are not included in those totals. That may also include some which were either lost in transmission, and lost or unreadable on the old tapes.
Phil
It includes the following:
547 VO1 images targeted at "STAR" or "MARS" during cruise -- there's your approach and calibration images;
8 VO1 images of the bicentennial emblem;
I don't see any VO2 approach "STAR" images, but there are the PRE_ORBIT images of MARS, 91 of them.
One thing I know for sure that the PDS archive does not include is the Earth-Moon departure images. I tried to inquire with someone at the geosciences node about these but I don't think she understood that I was looking for original data, not cruddy old press-release images; she didn't seem interested in pursuing them.
You can explore the file for yourself here:

Thanks again!
Phil
This is an image that, as far as I know, has never been compiled or published before. Earlier I posted mosaics of images taken underneath the two Viking landers using small mirrors on the sampler arm. This is another one. It's from Viking Lander 2, showing images taken over three sols far apart in the mission, looking at the area near Footpad 2. This footpad carried a temperature sensor. They needed to know if it was buried or not - Viking 1's was buried, this one is not. The sensor is near the right end of the mosaic, but I couldn't tell you which object it is.
Phil
(EDIT: I changed 'left' to 'right' in the last sentence - it's correct now. I forgot I had flipped it to remove the mirror reversal.)
Very cool - I have been transported in time AND space!
...And by the way, phil : you did a GREAT work !
i would say that the temp sencer is this ( in red ) and it's cable ( in green )
[attachment=20535:vik2_foo...d_images.png]
Here is the comparable mosaic of images of the footpad temperature sensor from Viking 1. This sensor, on Footpad 2, was found to be buried (or partly buried?) in the fine drift material which covered the footpad itself. Like the Viking 2 mosaic, I don't think this was ever previously assembled like this and published. The images were taken on sols 40, 203 and 520.
Phil

But quality is not perfect ...
Beautiful. Thanks!
Always love looking at Big Joe...wonder how he looks now. IIRC, V1 observed that a small part of his sand-cap fell off at one point.
Not his cap but the drift at his base!
Phil
Was it? I always thought that a piece of the cap fell off & impacted the base dune, but by now I should know better than to trust a 30+ yr.-old memory.
(My God...I'm old now!!!)
Thanks, Phil.
The only visible change was at the base, no change on top, so that can't be right. I'll post pics tomorrow.
Phil
Oh, I believe you, man; love to see the pics!
As I recall, NASA stated that this was the first example of small-scale natural erosion on another world ever observed (actually, unless the MERs or Pathfinder saw something as well it might still be the only one. Not sure if the sublimation seen by Phoenix counts, and can't call the polar landslides "small-scale".)
Viking 1 saw a second similar change later, as well. Spirit saw the little dust ripples move during a dust storm, with a nice animation posted on here at the time. We also saw tracks filling in with dust where we crossed old tracks (Home Plate, exiting Endurance, etc.) Pathfinder wasn't on the surface long enough to catch anything, and normally the MER rovers were not in one place long enough to see any changes.
Phil
Here are the two Viking 1 changes with a little bit of super-resolution to sharpen them. This is from the forthcoming Mars Exploration atlas - first draft now finished.
Phil
I should add that the Viking Lander imagery is ripe for re-analysis, looking for smaller overlooked changes. It can be tricky getting the lighting similar enough, but there's lots to do here.
Phil
Awesome. I forgot all about the Whale slump.
Thanks, Phil; anxiously awaiting publication of your atlas!!!
Here's another comparison image showing changes at the VL1 site:
That's fascinating Phil, thanks. I honestly wasn't aware they'd even done that.
...And another one, done using the same techniques, and just found in my archives. Enjoy too !
Tremendous, I really dig that last one...
... thanks for posting...
Thank you for these images and explanations.
I like see "new" images of old missions !!
Here is the complete panorama :http://infonetservices02.chez.com/VL1_Cam1_Color_HD.jpg
Wauw! to that complete panorama, new desktop!
Finally full size, high-res, color panorama from Viking. Spectacular!
A little experiment. This is a super-resolution composite of five HiRISE images of Viking Lander 2.
Phil
Wow. That is sharp.
When I processed and built the Curiosity dusk panorama
http://www.unmannedspaceflight.com/index.php?s=&showtopic=7591&view=findpost&p=198007 ,
I knew that a similar imaging experiment was done during the Viking Lander 1 mission.
It was ordered by Carl Sagan himself who was a Member of the Lander Imaging team and who wanted to see how the Martian landscape looked like at dusk...
Here is his panoramic picture taken on Sols 163 and 164 (BB4 diode), fully processed and colorized using the real colors retrieved from images taken at sunset.
A tribute to Carl Sagan and to the Planetary Society. Enjoy !
That's a very nice result! Thanks for working on it.
Very nice, Olivier!
Phil
Thanks a lot Phil and Tom for your kind comments.
Now as a tribute to your superb work, here is, fully reconstructed, the famous 1976 "Viking Sunset" picture embedded inside a late-afternoon panorama with colors fully corrected also... Enjoy my friends !
Ahhh, that's very nice Olivier ! Thanks for doing this work !
With Viking pictures, there is something mythic, legendary, that the other landers on Mars don't have IMHO. We can truely sense the feeling of the wind of exploration, the very beggining of things to come. This is images like these -processed by you Olivier- that gave me chills down my spine, and the envy later to process my own pictures. Thank you for doing this .
Many thanks Ant103.
...and here is the famous original painting from Monet and from which the Viking image was made : "Plaine de Chryse, coucher de soleil" seen in the collections at the Marmottan Museum in Paris.
I think the value of that razor sharp pan is considerable. Seeing the entire area in context to itself is really different than in seeing just segments of it. My impression all along was that landing site was pretty level all around, but it isn't. Looking at the whole thing you really see the dips and rises and and elevation changes and appreciate just how much topography is there. The site is FAR more interesting than it was 30+ years ago, LOL.
A frosty view of the Red Planet to wish you an Happy New Year 2014 to you all at the UMSF Forum
Thanks! It's nearly as cold as Mars here in Ontario this morning.

Merci 4th rock from the sun,
J'ai les dates (Sols) pour les expériences "Labeled Release" des Vikings, et je cherches celles pour les expériences de "Gas Exchange" et "Pyrolytic Release". J'aimerais bien pouvoir ajouter un tableaux qui résumerais bien toutes cette série d'expérience dans le livre et à la fin du chapitre sur les Panoramiques des Vikings !
Depuis le temps que je cherches ces informations sans les trouver !!!
________________________________________________________
Thank you 4th rock from the sun,
I have dates ( Soils) for experiments " Labeled Release" of the Vikings, and I searched for those experiences " Gas Exchange " and " Pyrolytic Release" . I wish I could add tables summarize all of this series much experience in the book and at the end of the chapter on Panoramic Vikings !
Since the time I searched without finding this information !!!
This gives some Gas Exchange information:
http://onlinelibrary.wiley.com/doi/10.1029/JS082i028p04669/pdf
(if you have access)
And this has information on the Pyrolytic Release (Carbon Assimilation) experiment:
http://onlinelibrary.wiley.com/doi/10.1029/JS082i028p04659/pdf
Also, I have some information in text and tables in my International Atlas of Mars Exploration.
Phil
Does anybody know where I could learn what the final orientation of the Viking 2 high-gain antenna and surface sampler boom housing were when its batteries died?
I am attempting to align a 3D-model of the lander created by n1ckdrake with PSP_001976_2280. Knowing the position of these moving parts would help make the match.
I have tilted the lander 8.2° down in the direction specified by the "Generalized Working Map of Sample Field" and matched the virtual camera orientation with the emission angle of HiRise.
Attached is a current best-fit. Any suggestions for improvements?
The sampler was last used on sol 958, and as far as I can tell it was fully retracted with the housing facing pretty much straight ahead. Looking quickly at images taken after that date, that is my impression.
I don't know about the HGA, but if it ran searches for Earth after loss of communication (which I assume might be possible) we wouldn't know its orientation. It is small enough that it's not going to make any difference to your fit.
Phil
I processed five HiRise images of Viking 2 landing site: PSP_001501_2280, ESP_016665_2280, ESP_037974_2280, PSP_001976_2280, PSP_002055_2280.

Phil and others interested in Viking, we are (slowly) curating the largest (and growing) collection of original Viking artifacts, documents, images, etc...
The purpose is to educate the public AND provide access to preserve the history, engineering, science, and artifacts, and to prevent further loss and inaccessibility, of the same.
You can see a tiny bit of our curated materials on our website, Facebook and Twitter.
Let us know if you have particular interest areas and keep in touch. We will showcase individuals work using Viking materials, as well as making the originals available for research and non commercial use.

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

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)
Panorama Viking Lander 2 Camera 2 in native High resolution colors :
- http://vandenk.free.fr/VLHDColor/HIGH-RESOLUTION-COLOR-RAW.jpg
- http://vandenk.free.fr/VLHDColor/HIGH-RESOLUTION-COLOR.jpg
I made a nice http://vandenk.free.fr/Anim_HTML5Canvas.html 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 : http://vandenk.free.fr/VLHDColor/22b057BB1&HighColorX2.jpg
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
Hi - do you mean the polar projections themselves or the versions reprojected to a HiRISE base?
Phil
Polar mapped on top of the HiRISE base.
OK, I am posting four images illustrating this mapping, two for each lander. Spread over 3 posts.
Phil
OK... over 2 posts - the first two were combined into one.
Phil
That is epic! You have a lot of skill doing this! Could you post them separately so I can use them as overlays for part of my Google Earth project?
Hi - it should be easy to crop each one as needed. They are in pairs because they had to fit the pages of a book. Try cropping yourself first, I will help if you can't do it.
Phil
At Antdoghalo's request I will post maps like these for some other sites, but as they are not Viking I will post them under 'Martian Cartography'.
Phil
Hi Phil, do you have a link for the topic 'Martian Cartography'
I suspect that Phil means this:
Unmanned Spaceflight.com > Mars & Missions > Mars > Martian Cartography
