I believe fredk is only active on this discord server and maybe facebook, but I might be mistaken. This is their website: https://cosm.ca/msl/details.html
I might make a version of this myself sometime, but I know [@Landru79](https://astrodon.social/@Landru79 ) is already working on one, maybe check his BlueSky page tomorrow.

This is possibly the most incredible tracking video of a rocket launch that I have ever seen, and Shuttle had some really incredible videos too!
Just look at those gorgeous flame dynamics and then the booster separation...

Just a few hours ago, the Perseverance rover captured this afternoon view of some wispy clouds above the Nili Planum region on Mars.

I just realized I never shared pictures of the red sprites, that I caught last year on August 14th.
They occured over a large thunderstorm complex in the Franche-Comté region in France, about 400 km from my location.

Quick reminder, tonight at 6:30 p.m. CDT (one hour from now) I will be presenting my virtual #LPSC2025 poster about mars rover photogrammetry and image processing.
You can find the zoom link on my iPoster, or if you comment under this post I'll send it to you via DM.

This little fella is a #tardigrade and I absolutely adore how chubby it is with it's eight little legs. Slowly floating through space - umm I mean a water droplet.

But first, this thing hadn't been used for years, so I had to clean it a bit. Maybe it was also just an excuse to understand how this thing works :)
It's an inverted design and has two optical paths, one for the binoculars and one for the camera.

So a few weeks ago, a relative of mine was looking for a new home for his old ZEISS research microscope.
And while I'm not a biologist - I'm a pretty big optics and photography nerd so I obviously couldn't decline the offer.
Let me take you onto a little journey to the #microcosmos 🧵

Of course this landing wouldn't have been possible without the Sky crane. Lowering a the rover under a rocket powered jetpack still seems nuts to me, but it worked flawlessly - TWICE!

Some of the most amazing images were definitely taken by the Descent Stage Downlook camera, mounted to the Sky crane.
The rover deck is pristinely white, but a lot of dust is blown up once the rocket exhaust impinged on the surface, obscuring the rover at touchdown.

I can't believe it has already been 4 years since the Perseverance rover landed on Mars!
The rover was equipped with six engineering camera that captured more than 26.000 images during the landing!

Just a little over one year ago, the Juno spacecraft made its first of two very close flybys of Jupiter's volcanic moon Io.
This picture from JunoCam was processed to approximate true color.

I used a high pass filter to transfer only the small scale details of his animation to a common background image, eliminating the flicker almost completely.
For the version above I also applied interpolation with RIFE 4.4 to create a smooth video.

This outbreak of local dust storms was captured by the Mars Express HRSC camera on November 16, 2006.
HRSC captures Mars with many different filters, some looking ahead of the spacecraft and some behind.
These images are taken over the course of about one minute, allowing for some nice short duration animations of moving clouds or dust.
ESA published this interesting article about the image in 2020:

This is based on the skimage.registration code example with a few tweaks to ingest PDS data and make a three color image.
I also had to tune a few parameters so the registration tracked the features correctly.

For those wondering what this is, color images like these taken by the Rosetta OSIRIS NAC camera are not taken instantaneously, but each filter is taken sequentially.
This creates parallax between the filters which causes lots of headaches to the people processing these images...

I was out with some friends today to photograph C/2023 A3 Tsuchinshan–ATLAS, but unfortunately some clouds came in and obscured the view.
Thankfully I still managed to catch it before it became completely hidden.

This is Comet C/2023 A3 (Tsuchinshan–ATLAS) passing by the sun while she fires off one CME after the other.
Mercury also makes an appearance on the left.
These images were taken by the LASCO C3 coronagraph on board the
ESA / NASA / SOHO spacecraft.

I applied some further processing to this amazing family portrait of our Earth-Moon system taken by the JANUS camera onboard ESA's JUICE spacecraft.
This is approximately how it would appear to the human eye.

Afterwards I got a great tour around ESOC from Ignacio Tanco, the JUICE Spacecraft operations manager.
My highlight was seeing the JUICE engineering model in person. It's so much bigger than I imagined, especially if you consider the huge solar arrays that are missing here.
If you look closely, the blue box shaped object on the left is (a replica of) one of the JMC cameras that took these amazing photos.

If you followed my boosts of @npub1wg6…p0eg toots, you may have already seen that I got to visit ESA in Darmstadt last week to process some pretty cool images from the ESA JUICE lunar-Earth flyby.
This is the fantastic timelapse video that Mark put together from the images I processed:
