Fun that only a sort of hemispherical 'cap' on the antisaturnian side of Titan ever gets *truly* dark, with the rest sitting in various degrees of moonlit twilight at their gloomiest. That big tall atmosphere acts like god's own lampshade!

Cool views of lunar highland mountains from Apollo 17. Zoom to examine and you can get a good feel for the hight and ruggedness of the terrain.

Excerpts from a NASA/NASA contractor public info publication in my collection. This one, from North American Aviation, was tucked into newspapers across the US ahead of Apollo 4, the first flight test of the Saturn V, in November 1967.
I post one of these in its entirety on my Patreon every Sunday.

A bit more TTT - working on the interior layer of the cylinders at the moment. Each of those tiling plates is about 50km long!

Cassini spacecraft leaving Earth on top of Centaur upper stage.
Back in October 2017 I made a series of Cassini themed artworks as a tribute to this amazing mission that gave us most breathtaking images of the other worlds.
Painted in Procreate on iPad Pro.

I've heard about planet WASP-76b showing hints of optical phenomenon called Glory. It looks like iridescent rings caused by liquid droplets in clouds. In this case the liquid droplets are made out of molten metal in the clouds of this hot Jupiter planet.

LOG 8: Z-Pinch Fusion The Runaway is a rapid transit vessel (colloquially, a "torchship"), designed to transport cargo and passengers as quickly as possible on intrasystem trips between wormholes. During the majority of a journey, the vessel acceleration is between 8 m/sยฒ and 11 m/sยฒ, the comfort range of gravity for most sophonts. While this shaves days off of voyages and reduces crew time spent in microgravity, it requires a great deal of firepower. The Runaway's comparatively tiny habitat sits on top of a massive pair of fuel tanks and z-pinch fusion engines. As plasma fuel is injected into the fusion chamber, the engineโs capacitor banks deliver thousands of electrical pulses per second, creating magnetic fields strong enough to initiate nuclear fusion. This magnetic field โpinchesโ the plasma along the engine's z-axis into a blinding blue jet of super-heated gases, pushing the ship to its cruising acceleration. Engine Schematic: fuel tanks deuterium capacitor banks shadow shield outer electrode inner electrode plasma electric current The magnetic field follows the direction of the electrical current. magnetic nozzle helium, hydrogen, and neutrons FUSION Image: Bip grumpily holds up a sign in front of one of the deuterium fuel lines with โ3Heโ written on it. Bip: Ideally, I'd have one tank of ยณHe and one tank of deuterium, that would be more efficient than reacting doot with itself... Talita: Beggars can't be choosers. Also, fusion engines aren't the only propulsion here! Image: She points at a small multi-nozzle rocket on the side of the Runawayโs habitat. Talita: On both ends of the vessel are rings of reaction control systems, aka RCS. These smaller chemical rockets are used for fine maneuvering and approaching dock, since fusion engines are illegal to operate too close to habitation. While fusion engines have less radioactive exhaust than fission engines (which use a process similar to a nuclear bomb for propulsion), they still emit deadly neutron radiation when operating. To protect the inhabitants from being fried by their own engine emissions, there is something called a "shadow shield" between them and the thrusters. This is a block of material that absorbs the thruster radiation and creates a cone of protective shadow around the body of the ship. Image: A diagram of the Runaway shows shape of the shadow cone, and the size of the habitable area of the ship (green) relative to the rest of the vessel. The main habitat is a four story structure under a 12th of the total length of the ship, with a short cargo bay hallway in the upper section of the spine. Most of the length of the vessel is occupied by fuel tanks, shielding, and the engines. Habitat (green) cargo bay (green) RCS (purple) shadow shield (dark blue) radiators (red) Neutron Radiation Zone (white with skulls and crossbones) Radiation Shadow Cone (light blue) This stellar flamethrower also creates a ton of waste heat, which in the insulating vacuum of space, dissipates very slowly. In order to prevent heat from traveling up the spine of the ship and turning the habitat capsule into a multi-story oven, heat from the propulsion system is diverted to the radiator wings. The radiators pump waste heat away from the engine and spine of the ship, giving it more time and space to dissipate, and can glow red-hot while the engine burns. Their triangular shape allows them hide within the shadow cone during burns, and extend to cool faster and provide maintenance access when the ship is coasting or docked.

A bit of worldbuilding-related WIP stuff for my personal project (TTT) featuring my beloved 5th-Percentile Morlock/Queensland Gollum.
And some solipsistic fanart of my own work in the Shipbreaker's Toolkit (again, Mothership).
This processing setup has proved to be really fun and has produced a lot of neat illustrations in the past week or two -- this will be the first of many, hopefully.
