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 -------------------- ... because the Solar System ain't gonna map itself.

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.

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. http://www.astrosurf.com/nunes/explor/explor_vik.htm -------------------- |

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 -------------------- ... because the Solar System ain't gonna map itself.

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 -------------------- ... because the Solar System ain't gonna map itself.

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 EDIT - the touchdown in the second image was made just before the image was taken. The arm touched the surface, was raised up, then extended to push the rock. As it was retracted it scuffed the surface to leave a scrape mark seen in the third image. The XRFS trench was dug later, but the arm struck a buried rock and did not penetrate enough to collect a sample. Phil -------------------- ... because the Solar System ain't gonna map itself.

Here's a pic from Viking:
