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.

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).
