Presumably we will see a HIRISE image of the Pathfinder site at some point, so I am posting a polar view of the site here for comparison. I started with the Presidential Panorama. There was a slight mis-match between the ends of the pan - as if it had been slightly cropped for posting - which I can't fix, but it doesn't do too much damage to the polar view.

Regarding the final position of Sojourner. The rover was designed to circle the lander if communications were broken with the lander. But lander communications with Earth were lost first....isn't it possible that the lander was still functioning and communicating with the rover for some time after that happened? If so, Sojourner "might" be in the same spot it was last seen in.

Regarding the final position of Sojourner. The rover was designed to circle the lander if communications were broken with the lander. No - that's what I thought, but actually - it was due to go back to the lander, but at the same time it had a keep-out zone at the lander. It would have kept trying to get closer, whilst nudging the keepout zone...and probably turned right and circled the lander not by design, simply as a symptom of two fighting commands..get close and keep out. However - eventually, the rovers knowledge of its own location would drift and it could have gone basically anywhere. The lander had no commands to send to the rover, and I think the lack of communication from the lander was probably a lander failure, not just a comms failure. But to be honest, who knows. Personally, I give the rover a 50% chance of still being at Chimp, a 25% chance of being near the rear rover egress aid, and a 25% chance of having gone rogue and gone crazy Doug |
