Yeah, there is no go-around with a glider, so we have to practice landings very well before departing on such a flight.
There are established meadows that are (probably) safe to land and we always keep them in safe gliding distance in case the thermals run out.
I really like the challenge of it, plus its a very calm and peaceful way of flying.

2026-05-04 13:42:58 UTC

Some photos from the glider flight I did on Saturday - my furthest one so far, crossing through Austria and well into the Swiss Alps!
It's always a joy to see these amazing mountains from above!

This video isn't an uninterrupted timelapse but rather combines several intermittent image sequences that were captured during the flyby.
It was originally published by NASA on Instagram. Most of these frames have not been published in full quality yet.
https://www.instagram.com/reel/DW7AKrtjQQl/
I spent a lot of time stabilizing the images since the original video was very jumpy and flickery. I also used frame interpolation to make the motion in the video a bit smoother.

The Total Solar Eclipse from Artemis II

I spent the afternoon and evening color correcting and stabilizing the video. This proved rather difficult because the video already had some kind of processing applied to it.

I was ready to go to bed late last night, but continued to listen to the audio descriptions from the astronauts which were incredibly captivating. In my mind I was painting a picture of this scene, and the images certainly didn't disappoint.
This is a HDR merge combining the long exposure art002e009573 with the shorter art002e009571. I also fixed the motion blurred stars with deconvolution and applied some noise reduction and slight color adjustmens.

I really can't stop looking at this photo - We usually think of space as being entirely empty and dark, but our Sun has a lot of dust around it that we can rarely see. This so called Zodiacal light is giving the moon this eerie backlit glow.
And four people really have been there and witnessed this yesterday, absolutely blows my mind!

The resulting transformation has an RMS error of ~1.7px which might be limited by the precision of my GCPs and the fact that +tpers ignores the oblateness and just uses a spherical Earth.

This required switching to the tilted perspective projection which needs tilt and azimuth values that can't directly be calculated.
At this point I gave in to the LLM temptation and had Codex write me a custom optimization routine to fit the affine transform, tilt value and even optimize the capture time since the EXIF time is often slightly off.

I converted the Ephemeris file published by NASA (https://www.nasa.gov/missions/artemis/artemis-2/track-nasas-artemis-ii-mission-in-real-time/) to a Spice kernel, then used Spice to calculate the sub-observer point and distance to make an initial nsper projection. I then used QGIS to georeference the image to the NASA BlackMarble night light image (https://science.nasa.gov/earth/earth-observatory/earth-at-night/maps/).
Unfortunately, an affine transform couldn't fit this perfectly, since the image is not exactly pointed to nadir and needs perspective correction.

You can actually see the small blue leader develop above the cloud before it fully discharges as a gigantic jet with vibrant purple and red colors.
After the jet disappears, the leader flickers a few times and surprisingly produces a second jet shortly afterwards. That's something I have not seen before!

Gigantic jets (part of the Transient Luminous Event phenomena) typically form over intense tropic thunderstorms. Current research suggest they are initiated by intra-cloud lightning that triggers a discharge up into the ionosphere.

I started with some 50 year old permanent slides shown in the first post. The first one shows a fruit fly and the second one a brine shrimp (sea monkey), both under darkfield illumination.
My camera adapter hadn't arrived at this point, so I was just taking pictures through the binoculars. Though that will give you a better feel how it looks in person, like diving into an entirely different universe.

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 🧵

I mentioned in the beginning, that Perseverance captured more than 26.000 images during the landing. Last year I processed ALL OF THEM to make a complete remastered video of the landing.
Thanks again to @npub12g5…4qf6 who helped me with the editing and rendering.

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 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 animation was originally processed by Andrea Luck (@npub1zc8…nxvk) who did an amazing job colorizing the individual grayscale filters with an RGB triplet from the middle of the sequence.
Because the different filters from HRSC have very different spectral responses, some flickering remained in the sequence.

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:

I'll leave you with a very preliminary false color (IR Orange Blue) image. Still needs more work and eventually I'd like to make a true color calibration if the necessary filters are available. 🔭

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.

2024-11-21 22:38:24 UTC

What I'm applying here is called optical flow, the software essentially calculates how each part of the image moved relative to the reference and then warps the image to match.
This worked surprisingly well for these images thanks to the large amount of detail in the image.

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 wanted to try if I could pull any details out of the comet through image stacking, with pixel rejection tuned to remove the darker clouds.
The first results were promising, but the tail didn't really get much more visible, even with aggressive post processing.

Towards the end of the timelapse, the sun fires off one CME directly towards Earth, a so called halo CME which often causes aurora here on Earth. It should arrive in a few days.
The energetic particles from the associated flare create lots of bright streaks when they hit the image sensor.

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.
