Oppy drove back uphill a bit in Perseverance Valley. Here is a stitch from Sol 4879 (10/15/2017?)
I ran it through a slight rinse in my De-Convolution Machine ... -------------------- CLA CLL

Wow! That's radical. Don't think I've seen that before. I only see a trail from the wheel on the right. Was it pivoting?

The 4883 drive looks like a very short bump upslope, towards the direction we're looking in the image I posted. We're sitting almost exactly on our tracks from the downslope drive on 4831 (check Phil's map) and the obvious track is from that drive. It's harder to see the track from the other wheels I guess because of the bigger rocks on that side.

It's been awhile since I have worked on images.

Sol's 4878-4880
I used the wonderful already generated ASU falsecolor images for this, just mosaiced them all together. Full Resolution https://www.flickr.com/photos/43581439@N08/...744050/sizes/o/ |

It's been awhile since I have worked on images. It's been awhile since I posted - thanks for your wonderful work! -------------------- Lyford Rome

Yes, James, thanks! I have been using your images to assemble a photomap base for more detailed mapping of this area. This is still an ad hoc mosaic, not controlled by HiRISE, but it will be warped to fit HiRISE control later, and then the detailed path can be plotted.

Looks like what may be a DD on 4916: We had quite a few cleaning events for the past few weeks. Paolo -------------------- Disclaimer: all opinions, ideas and information included here are my own,and should not be intended to represent opinion or policy of my employer.

Where opportunity is headed downhill there are active sand dunes which would ensure regular cleaning took place. That would be a good location to park opportunity when the wheels pack in. There is an argument for parking opportunity for two years there in any case because of the radio experiment that can be done to investigate the core from a parked lander. There is a plan to launch the insite mission next year to do this radio science experiment, but if this failed then opportunity could perform the radio science experiment whilst filming moving dunes |

Where opportunity is headed downhill there are active sand dunes which would ensure regular cleaning took place. Hmmm... I think that where there's sand accumulation there's a dip in strength of winds. That's why the dunes get bigger and bigger. In the past we have seen cleaning events near clean bedrock. QUOTE There is an argument for parking opportunity for two years there in any case because of the radio experiment that can be done to investigate the core from a parked lander. If there was one I never heard of it. SS never mentioned that. Parking the vehicle for two years would be a major operational nightmare. We have only FIVE rover planners left which would still need to earn a living for those two years, so we would need to find another job for two years. After this forced pause, resuming operations would be quite difficult. It was so when we had to park Spirit for months at a time. I can't imagine what it would be like to resume driving after two years. I liked doing the radio experiment on Spirit, I found it mind bogglingly cool and was part of the team to support it but I hope we can postpone this to when Oppy's wheels fall off or the motors stop responding to our commands. We have tested driving our testbed with only four active drive actuators...

stitched sequence of lossy pancams from sol4924, ICE only being able to deal with ten of the 27 frames but at least gives a useful uphill view of the channel.
ps.. lots of good stuff in A.J.S. Rayl's latest on Planetary.org |

This is hideously distorted because I am not working from a topographic dataset to reproject the images - later, this will be projected onto HiRISE for control. But it gives an impression of the distribution of features around us in mid-December.
