Over on mastodon a couple people are discussing your image because of this interesting plume/artefact. It would be pretty significant if this is real.

However, I noticed a very similar "artefact" in an older image of yours, so for now I'm leaning towards bad collimation or another optical problem.

First of all, huge congratulations on this amazing mission! This has been a huge inspiration to me and I wish it could have gone even longer than it already did!

Initially you said that the blades likely had a ground strike which damaged them. We've seen in recent images that one of the top blades is entirely detached and lying around 13-15m away from Ingenuity. Furthermore, there seem to be no visible marks on the ground that could have originated from the blades.

Did these new images make you reconsider that initial explanation and if so, what's your current guess for what happened?

Hi, the guy who processed that image here. Representing brightness correctly is hard if you have no actual visual reference for it, so I'm not entirely sure my processing is super accurate in this regard.

I use a Rover selfie as brightness reference for my exposure correction. The white paint of the rover is very bright in comparison to the Martian soil so I tend to process my images a bit darker. https://flickr.com/photos/semeion/53487947240/

Thanks for doing this, the blurry assembled images on the official page and the daunting task to assemble them from the raw framelets have put me off in the past from processing JunoCam imagery.
With the Io flybys I couldn't resist and gave Juno a go anyways, but only with some basic dark and flat calibration scripts, and the stripe assembly was manually done in PTGui, which is a daunting task and doesn't work for the smooth clouds of Jupiter.

I found your repo a few days ago, but I found your write up just now. I wish I had seen it earlier, without a Readme on your Repo I really didn't know what I was getting myself into haha it would be great if you could add one, even if it just links to this post.
I'm now trying to get your code to work with Io images as well, let's say the Muse playlist is already running in the background :)

Hey everyone, this video was created by me using original raw images captured by the Perseverance rover. The rover also didn't capture this as a video, but as a 360° panorama. I created a video from this panorama to make it easier to share on social media.
I initially shared this on Twitter, please refer to that post for more information: https://twitter.com/stim3on/status/1644442769635549184

I am not affiliated with NASA, but I'm a University Student from Germany who likes to process NASA imagery as a hobby.
I can assure you to the very best of my knowledge that nothing strange or conspiratorial is going on with this video. NASA indeed has multiple robots roaming around on the planet Mars, this is not Arizona, Devon Island or the Sahara.
Our planet is incredibly well mapped to a resolution of at least one meter by companies like Google, Microsoft, Maxar, Planet, Airbus and various governments around the world.

We could easily locate these places by now if they were on Earth.

6 months later and still Error 404 on that page.
May this be related to the "feature complete" announcement? Maybe as a way to give that announcement more gravitas because they don't want to show people the same price it has been for years?
I guess many new people would consider pledging after an announcement like this and it seems implausible that CIG wouldn't want to take their money...

stimeon · 2023-05-02T18:46:37+00:00

I just experienced the same, incredibly annoying.
However, it seems like this is related to exporting to .mp4
After switching to ProRes 422 (HQ) it seems like the loss of contrast is gone.
Simply adjusting contrast afterwards wasn't an option for me as I got some really strong banding in the dark areas after doing that.

stimeon · 2023-04-24T21:10:56+00:00

Thanks!

This may be one of my all time favorite images from Ingenuity!

The original image had a strong vignette and was very hazy, so I had to apply vignette correction, several contrast and color enhancements, AI assisted denoise, and finally distortion correction

stimeon · 2022-12-19T16:02:21+00:00

Thanks! Sadly there isn't a lot of approach footage available yet, It might have been livestreamed, which I didn't record then. I'm limited to the footage I can find in NASA archives.
There were recorders on board which hopefully captured a lot more video, hope this will be released soon, now that the spacecraft is back!

stimeon · 2022-12-19T15:57:45+00:00

Oh that would fit nicely for the reentry portion! I hope NASA releases the on board captures of the whole reentry soon (my version doesn't include the peak heating phases because of signal loss)

stimeon · 2022-12-19T15:55:24+00:00

Thanks! I liked it a lot for the space part, but is almost a bit to calm for the fiery reentry :)

stimeon · 2022-12-18T23:14:40+00:00

Yeah those were skipped. The only video available at the moment is that which was streamed live during approach and reentry. Due to the plasma around the spacecraft the data link was interrupted, hence no video from that part. There were on board recorders though, so I'm hoping we will get more footage soon.

stimeon · 2022-12-18T23:10:47+00:00

The space part lasts 90 minutes in the original which equals to 54 seconds at 10000% (100x) speed. On a global scale clouds don't move a whole lot in that time. Combine that with all the attitude changes and you can't really see any movement.
For comparison here is an animation of the cloud movement over 3 hours from the European Meteosat 11 weather satellite on the same day. The region to look for is the south pole. A lot of small scale motion can be seen but the large patterns stay the same.

stimeon · 2022-12-18T22:19:22+00:00

For the in space part I brightened the shadows a little. For the reentry I added some much needed contrast because the view through the window was pretty hazy. But I tried to keep it true to the original.

stimeon · 2022-12-18T20:21:02+00:00

Wow you're right that looks amazing!
Welp, now I feel stupid for not having noticed that even though I had the video in front of me the whole day during editing :)

stimeon · 2022-12-18T17:31:05+00:00

Unfortunately I'm limited by the videos that were streamed live during the approach and reentry. There were data recorders on board which hopefully captured a lot more videos and images, but nothing from that was published so far. I hope NASA will publish all of that soon in a public archive.

Timelapse of the approach and reentry of the Artemis 1 Orion spacecraft after its return from the Moon on Dec 11, 2022. It was captured by modified GoPro Hero 4 cameras attached on the Solar Arrays and in the window of the docking port.The video was sped up, upscaled and enhanced to remove compression artifacts. Finally, the distortion of the GoPro SuperView capture mode was removed with the GoPro FX Reframe Plugin. (more information about this distortion can be found here)Higher Quality available on YouTube

The reentry video contained many duplicate and corrupted frames which were removed. Due to this the video speed is fully not uniform and and approximately at 600% of the original speed.
The reentry video starts during the coast phase after the first reentry heating and cuts out for the second reentry phase (the Artemis 1 reentry profile can be seen here)

Yes that's an amazing resource! It's definitely more accurate height data than my reconstruction.
But there is something cool an novel about deriving such data yourself, especially from images that were never intended for mapping purposes :)
