Maybe life on Mars is disguised in the form of … regolith grains? 😃 🙃

This little fellow decided to take a walk and have some fun exploring its container.

@65dBnoise Did you notice the SHERLOC focusing sequence?
It was my understanding that since the cover failure, the focusing mechanism was out of order, but maybe they got it running again!
Except maybe it's focusing via changing the distance to the object, I didn't check for that yet.

@65dBnoise I bet there is an interesting story to be told about a group of engineers in the Marsyard working long nights to develop a plan how to regain focusing capability with Sherloc by incrementally moving the robotic arm :)

Well what a night it was...
I didn't expect very much since Munich is quite far south, but what unfolded surpassed our wildest expectations!
It took me a while to edit these images, in total I took more than 2000, but that also means there are some timelapses waiting to be processed :)

The large dishes belong to an old satellite ground station in Raisting, near Ammersee in southern Bavaria that was built in the 1960 and is still operating to this day.

@tom30519 Thanks Tom, it was a night worth remembering.
I wish you good luck tonight, though it looks like we might get clouded out instead :)
Some interesting whisky cirrus clouds are in the north right now.

Almost certainly not the best shot I got tonight but the first one that made it into Lightroom!

This is from southern Bavaria, the Aurora are just crazy right now.

To my European followers:
It looks like the solar storm might arrive earlier than expected (it already did partially!), which means very good chances tonight for Aurora over Central Europe!

The current model run from NOAA SWPC already predicts Aurora as far south as Cologne! And levels may very well increase during the night!

I wish you all good luck and most importantly clear skies!

Earlier today, the rover captured this long distance view of the Mars Helicopter. The new image shows possible footprints from an earlier flight to the left of the current location.

Here is the full mosaic that's made up of five individual SuperCam images.

I processed the images with AI noise reduction and color corrected them to approximate what the human eye would see.

I believe we can now reconstruct the last moments of 's with some certainty. The actual trajectory may be a little more complicated, e.g. turning while hopping, but we'll never know.

EDIT: there is a new theory about Flight 71, see comments.

@65dBnoise I'm not sure that this kind of bounce is possible. I was told by one of the Ingenuity engineers that the shock absorbers are so effective even on hard ground that a bounce on much more absorbent sand could never reach this high.

There is a new theory that these imprints on the backside of the sandripple are actually from Flight 71. The official landing location was apparently just a rough estimate and there don't seem to be any imprints at that location anyways.

stim3on,
@stim3on@fosstodon.org avatar

@65dBnoise As far as I know, only partial telemetry (the output from the kalman filter) is transmitted during a flight, individual sensor data and images are only sent after landing.
These data are stored in RAM during flight, and I believe there is a mechanism that reboots the system after an aborted flight. That's why there are no images and why there is almost no telemetry data to analyze from these flights, which makes it so hard to reconstruct.

@65dBnoise if was indeed just a popup flight without lateral drift, a fast vertical landing on the slope would induce quite a bit of roll. This could introduce significant gyroscopic precession effects on the blades which the team believes could have bent the rotors beyond their limits until they snapped off.

Here are two animations I made about how gyroscopic precession would bend the blades. I thought it might have bent them until contact but they are most likely too stiff for that.

@65dBnoise I made these animations almost two months ago, long before we knew about the new footprints.
I got the same feedback about the bounce height back then.
I never thought about an impact while the rotors were still generating lift, that could explain a larger bounce, but I doubt the heli could have traversed the sand ripple crest like that without any additional marks.

New site number 52 for on Sol 1129, but apparently at the same location. The rover appears to be stuck in a sand field, although that may not be the reason for its recent inactivity.

The hills are alive ... in this beautiful panoramic "painting" by Mars rover Perseverance looking east from its high vantage point in Jezero crater.

This composite image was stitched together from images taken on April 13, 2024. Needs more sophisticated image processing than my limited capabilities to bring out its beauty, to balance the colors and to remove the distortions.

The rover captured this scenic panorama a week ago on Sol 999 with the left Navcam.
In front of the rover lies Neretva Vallis and the Jezero Crater Rim where the mission is heading to in the future.

Also visible in the panorama, but very tiny, is the Mars helicopter which had its fateful last flight a few months ago.
It rests on the crest of a sand ripple now dubbed Valinor Hills.

The image was stitched from 24 Mastcam-Z and several Navcam images.

I reprocessed the Sol 1110 Ingenuity image with AI-upscaling to improve visual fidelity.

As @65dBnoise already noted, there seems to be disturbed sand on the other side of the sand ripple. We are still hoping for SuperCam images of the area to get a better understanding of what happened.

I've also just made a combined version of the Mastcam-Z images and Navcam images from Sol 1110.
Now you can zoom in all the way to Ingenuity's final resting place at Valinor Hills.
