My friend, Prof Corien Bakermans, just did a great interview for a CBC show about her recent study of tardigrade survival in simulated Martian soils. Give it a listen! #tardigrades #mars #regolith #astrobiology

Forschungsteam bricht in die Atacama-Wüste auf

Eine Gruppe von vier Wissenschaftler:innen ist unter der Leitung von Prof. Dr. Cyprien Verseux vom ZARM für eine zweiwöchige Exkursion in die Atacama-Wüste (Chile) aufgebrochen – um den Mars besser zu verstehen.

Only hydrated #minerals as a water source cover the needs to produce propellants and life support #water💧. Extraction from #regolith requires autonomous excavation, transport, processing of regolith and water treatment that present significant challenges. #Atmospheric water harvesting suffers from the extremely low residence time of air in the system. Compression is power-intensive 🪫 but can be competitive if the waste heat from the fission reactors is accessible https://www.sciencedirect.com/science/article/pii/S0273117725012864?via%3Dihub#s0185

The Perpetually Curious!Jan 18

RE: https://mastodon.social/@theperpetuallycurious8/115706997888373254

🌙 The full Moon appears about 40% brighter than geometry predicts due to the opposition surge, where regolith's microscopic particles hide their own shadows and can even produce coherent backscatter when Sun, Earth, and Moon nearly align.

✨ This hair-trigger optical effect reveals how alien dust transforms moonlight itself.

✍️ See the original post in this thread for the full article exploring regolith mysteries!

Laterite (Pedology 🟤)

Laterite is a soil type rich in iron and aluminum that often forms in hot, wet areas; most such soil is found in the tropics. Nearly all laterites are of rusty-red coloration due to high iron oxide content. Laterite soils develop by intensive and prolonged weathering of the underlying parent rock, usually under conditions of high temperatures and heavy rainfall...

Trying to live with #regolith-desktop on #debian 13. It's partially #gnome & partially #i3
That's what I figured out:
1. 100500 of key combinations it's not the problem. I know lots of them and use them without hints after a day.
2. It's really effective to arrange windows tiling with keys only. Although one need strong skills to make it fast.
3. The best thing: Regolith looks & feels like no-desktop-linux.
4. The worst thing: GTK-apps start is too slow!

I wrote up something about an #emacs application launcher that I am using with #Regolith and #i3wm. Enjoy! https://arnesonium.com/2025/11/regolith-emacs-launcher
An Emacs Application Launcher for Regolith

I run the Regolith Desktop Environment on my laptop, which I love because it provides a convenient GNOME wrapper and interface for the i3 tiling window manager. Regolith relies on a program called ilia for application launching, and sometimes ilia gets caught in some kind of CPU-churning state that locks up my whole system. I have not been able to figure out what is causing it, so I (of course) turned to Emacs for a solution.
