Cropped view of an extremely turbulent region in Jupiter's northern hemisphere with enhanced colours. Various shades of brown, orange, beige, and blue-green tint the countless cyclones and turbulent weather systems in the area, some of which may be as large as an Earth continent.

For this one, the processing is tailored to the image and guided by its own RGB strip, with AI assistance. I’m not retraining a neural network on a collection of HiRISE images. It’s still an experimental approach 🙂

tthomopoulos @tthomopoulos.bsky.social · 05/09/2026
Thanks! 🙂 It’s an AI-assisted experiment using the original RGB strip as a color reference to extend the palette into the monochrome areas, with local corrections. The aim is to preserve the terrain and textures. Colors outside the strip are inferred.

In Greek myth, Atlas bears the heavens; Argo carries the Argonauts. Here, ATLAS carries the material weight of Mars exploration: ACL landers, habitats and infrastructure deployed ahead of the crew. A speculative concept grounded in plausible mission logic.

tthomopoulos @tthomopoulos.bsky.social · 31/08/2026
Atlas carries the infrastructure. Argo carries the crew. ARGO is a speculative Earth–Mars transport with a detachable MDAV for descent/ascent, while the transit habitat, radiation shelter and propulsion remain in orbit. Concept art, not an engineering blueprint.

tthomopoulos @tthomopoulos.bsky.social · 30/08/2026
Atlas and Argo Atlas carries a fleet of ACL landers and pre-deploys surface infrastructure. Argo transports the crew. Together they form a speculative Mars architecture - an artist’s concept grounded in plausible mission logic.

ATLAS / ACL 🚀 A speculative Mars logistics system: ATLAS stays in orbit while detachable ACLs handle entry, landing and ascent. The same aeroshell supports two roles: cargo delivery or a pressurized human habitat. One carrier, many missions.

Absolutely, the lunar environment makes autonomy much harder. My point is not that it would be easy, but that the cost of permanent human presence could create a much stronger incentive to develop highly autonomous industry there.
010
tthomopoulos @tthomopoulos.bsky.social · 25/08/2026
You're right for now, but on Earth the constraints are very different. On the Moon, any permanent human presence changes the equation. That could make a much higher level of automation economically viable and create a strong incentive to achieve it.

tthomopoulos @tthomopoulos.bsky.social · 25/08/2026
The Moon does not have to become a human colony. Instead, its first major role could be that of an autonomous industrial world, producing structures and materials for space exploration. No permanent crews. Just machines building the infrastructure for humanity's next worlds.

Off-Earth : a speculative atlas of human habitats A first concept for a future human settlement on Mars: a partially buried habitat protected by the surrounding regolith, built around a large pressurized central dome. First step in a project exploring architecture beyond Earth.

Yes, broadly. I keep the original grayscale for the terrain structure and use the central RGB strip to guide the color extrapolation.
