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.

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 Phil I assume you worked with hi-res images? For comparison at this MSSS link are some VL2 mosaics (bottom of page). These are later versions of the ones I worked on during my internship at JPL in 1977. http://www.msss.com/mars/pictures/viking_l...ing_lander.html I have just photographic prints/negatives of the earlier versions, unfortunately they aren't in digital form. Nice to hear you got a chance to look at Tim Mutch's papers. He was certainly a great person to have had the privilege of working with. -------------------- Steve [ my home page and planetary maps page ]

Here by the way is a montage of the quadrant pairs in the MSSS versions of the VL2 Camera 1 pm mosaic. These are less than the full resolution however they are corrected for the VL2 tilt. Steve |
