“Rocket Summer.” The roar of rocket engines has long haunted the BIS, especially the sound of spaceplanes reaching for orbit: we review Rob Coppinger’s comprehensive analysis of such aspirational projects in the latest issue of "Odyssey" magazine. Don’t miss it! www.bis-space.com/publications/

#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

“On a moonless night, legend has it that Neptune will summon the starfish to the surface of the sea, lighting his path to the shore. Thus a lost mariner can reach safety simply by following “Neptune’s Highway,” these stepping stones on the surface of the abyss.”  Anon Starfish are truly ancient; they predate the dinosaurs by hundreds of millions of years and have survived all five of the Earth's major mass extinction events. Whether they can survive the current ongoing mass extinction event – the Age of the Anthropocene – remains to be seen. “𝗦𝘁𝗮𝗿 𝗙𝗶𝘀𝗵 – 𝗜𝗻 𝘁𝗵𝗲 𝗥𝗼𝗰𝗸𝗽𝗼𝗼𝗹𝘀 𝗼𝗳 𝘁𝗵𝗲 𝗡𝗶𝗴𝗵𝘁" “𝘕𝘢𝘵𝘶𝘳𝘦’𝘴 𝘯𝘦𝘷𝘦𝘳 𝘰𝘯𝘦 𝘵𝘰 𝘸𝘢𝘴𝘵𝘦 𝘢 𝘨𝘰𝘰𝘥 𝘥𝘦𝘴𝘪𝘨𝘯.” 𝘛𝘩𝘦 𝘸𝘰𝘳𝘥𝘴 𝘰𝘧 𝘮𝘺 𝘨𝘳𝘢𝘯𝘥𝘧𝘢𝘵𝘩𝘦𝘳 𝘧𝘭𝘰𝘢𝘵𝘪𝘯𝘨 𝘣𝘢𝘤𝘬 𝘶𝘱𝘰𝘯 𝘵𝘩𝘦 𝘵𝘪𝘥𝘦 𝘰𝘧 𝘮𝘦𝘮𝘰𝘳𝘺, 𝘴𝘶𝘮𝘮𝘰𝘯𝘦𝘥 𝘣𝘺 𝘵𝘩𝘦 𝘶𝘯𝘥𝘦𝘳𝘵𝘰𝘸 𝘰𝘧 𝘛𝘪𝘮𝘦 𝘪𝘵𝘴𝘦𝘭𝘧.
