It's #Spacetober day 7, Venus. #SciArt #spaceart Artwork of the Venera 9 spacecraft on the surface of Venus. The Venera probes were a series of ten successful missions sent to Venus by the Soviet Union in the 1970s. Venera 9 was launched on 8 June 1975. 1/2
A, hazy, yellow and rocky landscape, barren of life. The surface of Venus. Left of centre, sitting on an outcrop of rock, is the Venera 9 lander. There is lightning in the sky, although whether Venus has lightning is disputed.

It's #Spacetober day 6, rover/robotic explorer. Exploration of Europa In the future, a probe descents into an ice chasm on Jupiter's moon, Europa. Jupiter is seen in the sky, with another moon, Io, in transit. #SciArt #spaceart
Illustration in acrylic, modified in Photoshop. We are inside a chasm on Jupiter's moon Europa. Jupiter is seen in the sky with Io in front of it. The landscape is a mix of rocks and ice. A probe is descending into the chasm, emitting light that illuminates the chasm wall nearby.

More work on the docking area of the BIS Avalon. I'm trying to make it work in Lightwave 2026, and get render times low enough to animate it. I'm getting there at the cost of turning off GI. vimeo.com/1230288862?s... Also a big still:

If we ever do colonise Mars, robots will likely come with us. Structures like those here are unlikely to be permanent habitats, as they are exposed to radiation due to Mars planet lacking a magnetic field. In the longer term, underground facilities provide better shielding. #sciart #blender #scifi

#Blender animation depicting Mars 4100-3700 million years ago. The period is characterised by high rates of meteorite impacts, volcanism and possibly abundant surface water — however, the water is thought to have been localized rather than spanning the planet in oceans, as on Earth.

Just finished Susanna Clarke's "Piranesi", an utterly delightful read. Wildly original, I was about 40% in before I got a feeling for what was actually going on. I found "Jonathan Strange & Mr Norrell" superb, I'd say this is even better.

Lunar View, after Lucien Rudaux. The original lighting made the central peak pitch black, as it was completely backlit, so I moved the Sun to one side. The Earth is unrealistically large. Terrain in #Gaea, everything else in #Lightwave3d
