Here is a HiRISE photo showing the Conjunction resting places of Perseverance and Ingenuity. Note that Percy's wheel tracks can be seen. And to the right of the Rover is a curvilinear dark trace, possibly a dust devil track.
I wonder if this dust devil was seen in the dust devil monitoring program?

Animated comparison of two Navcam images before and after conjunction,
here on sol 216 and sol 232 at a local mean solar time around 08:00 in the morning.
Some grains are slightly displaced, especially around the rocks in the lower left quadrant of the image.
There also appears to be some slight movement on the surface of the small dunes,
if this is not due to image compression artifacts and/or moving shadows.

to me the changes in the two above images look a lot like camera noise

but i am used to looking at grain in photographic film ( 10+ years in photo darkrooms)

so that is what i see

There is a degree of illusion due to lighting differences between images but you can track the physical movement of some small granules. Perhaps in the interlude one of the gusts we have seen in the distance passed across the area.

Agreed some granules moved. That's not unexpected - we've seen that elsewhere on Mars over previous conjunctions.

Subtle. Mars can be so subtle.

Even for most locations on Earth, if you photograph a patch of dirt & rocks, wait 14 days and take another photo, you don't get much change.

Drive on sol 237 to 7/2246. Maybe ENE?\
Not many images yet, here's a couple of R-Navcam's from the end of drive roughly assembled using MS-ICE and de-greened, but looks like it also acquired some images mid drive

Back in the saddle again... here's the sol 237 circular panorama. We moved about 30 m east (and a bit north).

Quick note: Now that we're past conjunction & this thread has become pretty hefty we've decided that it's time for a new thread for events from sol 237 onward. Thanks! smile.gif

A few will take this knowledge and use this power of a dream realized as a force for change, an impetus for further discovery to make less ancient dreams real.
