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.

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