This is my next read on audiobook, not on my planned TBR this month. I continue my sporadic re-read of the Revelation Space books. Going in, I remember very little about it. 🪐📚 #hardsf #spaceopera #scifibooks #sciencefiction

The Type-711A Light Attack Craft designed by @l5resident.bsky.social and Tokydre for @thelunarwar.bsky.social setting. It's non-nuclear and lacks large lasers but it has more than enough missiles to be threatening.

Ich bin ja seit meiner Kindheit HardSF Afficonada, glaube deshalb auch, dass vieles möglich sein wird.

Reiche egoistische Spinner, auf unserem bislang einzigen Mutterschiff, werden aber eher so ähnlich scheitern, wie eitle Protagonisten des Monoskis beim Tourengehen.

A modular spacecraft in low-Earth orbit. It is a series of connected cylinders arranged axially. The front end is tapered and features a small docking port. The back end has a single large engine nozzle and 3 small foldable radiator panels on each side. The daylit limb of Earth is in the background.

Si vous aimez la #hardsf, et les conséquences philosophiques étranges de l'effondrement de la fonction d'onde et l'interprétation d'Everett de la mécanique quantique, vous apprécierez le roman de #SF "Isolation" de Greg Egan ⤵️ belial.fr/legacy/a/gre...

TJ Klune, Under the Whispering Door: it has hardSF-ness, a reasonably happy ending despite a dystopian premise, and the writing is superb. Klune writes gay SF-fantasy, but not erotica. You did say you want to broaden his reading horizons?

My latest (short) science-fiction story "Eclipsed" was published today. It's about how rare total eclipses might be, not just in the solar system, but the universe. See: bit.ly/eclipsedsfst...
#astronomy #astroedu #scifi #sciencefiction #hardsf #hardsciencefiction #eclipses #eclipsechasing

Eclipse sequence, showing how a total eclipse of the Sun happens, by Rick Fienberg (astronomer, astro-photographer, and veteran eclipse chaser.) Here the Moon exactly covers the Sun, blotting out its entire body, and allowing its faint atmosphere to become visible.

#SFFChat 24: Ask a question of your own to #sff participants!

What are your feelings on #HardSF - #ScienceFiction that tries to hew to actual known science? Slower-than-light ships, plausible extensions of current tech (and trends), etc?

If you like it, why? If you don't - also, why? 😀
