I updated my Sol3 MastcamZ panoramic with Sol11 pictures. The horizon was kinda blurry because of little bit out of focus pictures. Now it's in the past.

With, I hope, Damia's blessing, I took the medium resolution version of your panorama, cropped specifically around the delta, and magnified the vertical axis 8x.

This, to me, highlights the objective of the mission as well as any image now can. When we see the delta soar high and imposing we see the grandeur of Perseverance's aspirations. And all those smooth surfaces facing us conceal what we want to know about, and what, we hope, Mars Sample Return will fully reveal.

All that wide panorama of Jezero is beautiful, but the objective is right here, in this one formation, and the many parts of it that we cannot see yet.

Amazing Damia, you mastered this panorama! I can't imagine the number of hours you spent on that one.

Thank you Thomas & Olivier for your very kind words smile.gif

Indeed Thomas, it took me many time to get this panoramic right !

Hello to all,
we went back to the panorama of sol 4 and we worked mainly on the sound of the wind (repeated a few times in this movie). Earphones are not required.
it's a bit like being on Mars for 5 minutes smile.gif

An unprotected mic (eg a camera mic) in the wind can produce spurious low-pitched rumbles, I guess due to turbulence or oscillations around the mic. I don't know if that might be what we're hearing here.


Exactly, local dynamic pressure fluctuations cause the microphone diaphragm to move just as elastically-propagated pressure variations (aka sound) do. Although one person's noise is another person's signal, I wouldnt call it 'spurious'. We may try to use microphone data to measure winds and turbulence

Perseverance's Landing Vision System is still delivering surprises!

Fellow enthusiast Simeon Schmauss has done some remarkable work stabilizing LCAM images, and in so doing, spotted a large dust devil traversing across the delta during Perseverance's descent, northwest of where the rover would land only seconds later. Simeon's discovery is the first dust devil imaged by Perseverance. Also worth noting, we've seen dust devils from the surface and from orbit, but never from an entry system, before this.

Simeon clocked the DD moving at an astonishing 8.5 m/s. The DD was roughly 20m wide at its base and traversed between 600 and 1000m, depending on where you perceive the first discernable visual signal.

It's a remarkable discovery and a testament to the value of getting raw images to public expediently.

That is amazing. What a discovery! Thanks for linking to it.

I just watched the Anderson Cooper segment about Percy and Ingenuity on 60 Minutes https://www.youtube.com/watch?v=gRrFRL5v0ig He mentioned the early panorama of rover images put together by Sean Dornan. The project scientist Ken Farley was impressed.

There were 4 images of the Sky Crane/Descent Stage crash... I finally took some time to do a little something with them.
I wrote a very simple interframe interpolation program (thank goodness the camera didn't move)
A little cleanup and little equalize...

* the dust cloud around Percy (from the Sky Crane) is settling into the distant
* the crash plume moves slowly southerly on a breeze
* there is a local horizon before the Deltas
* the Hazcam dust cap goes away and we then see clearly on Sol 2 (almost the same local time)
* the actual plume images cover 18 secs (I really sped it up!)

Here is the GIF
