(19) TOUGH SF & SPACE KOALA

SF on X!

Which I suppose makes them somewhat unusual in an entry for SF books but that’s part of why my special mentions are, well, special.

Tough SF is essentially an SF blog or more precisely an SF blog on X (Twitter) – posting ‘real life’ or ‘near future’ SF, with a focus on concept art or real life designs of space travel or nuclear power (or both).

Space Koala is essentially also an SF blog on X, but with a tongue-in-cheek focus on “space memes”, “fusion dreams”, and a white-hot rage against the continued existence of the planet Mercury.
