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 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.

And to complement your good info, here is what was written a while ago + how Meridiani would have looked to the Viking Lander camera. http://www.unmannedspaceflight.com/index.p...st&p=105769 Enjoy ! |
