Summarised by Claude from recommending comments
"The year is 2066. A Caltech intern inadvertently notices an anomaly from a space telescope--something is approaching Saturn, and decelerating. Space objects don't decelerate. Spaceships do. A flurry of top-level government meetings produces the inescapable conclusion: Whatever built that ship is at least one hundred years ahead in hard and soft technology, and whoever can get their hands on it exclusively and bring it back will have an advantage so large, no other nation can compete. A conclusion the Chinese definitely agree with when they find out. The race is on, and a remarkable adventure

All of Andy Weir's books are really good. There is even a surprising one that's fun. Also recommend Saturn Run, by John Sandford, while we are on this topic.
on “How far could a spaceship go if we never ran out of thrust? (2020)” ↗…start for some, since it's written in space King's English, but what they load in the book is a gem. 2. "Eifelheim" by Michael Flynn. 3. "The Sparrow" by Mary Doria Russell. Wow. She's brilliant. 4. "Saturn Run" by John Sandford (crime novelist) and Ctein. 5. "Hunter's Run" by George R. R. Martin, Gardner Dozois, and Daniel Abraham (from the Expanse) - 30 years in the making. Technically more like second contact,…
on “The Challenges of First Contact” ↗Hard sci fi is hard to define for me personally. But, Children of Time by Adrian Czajkowski is worth a look, and maybe Saturn Run by Ctein and John Sanford.
on “The Realism of Our Times: Kim Stanley Robinson on how science fiction works” ↗…written by a retired, senior national security advisor to various (USA) Presidents from Nixon on. He was the China expert, who started young, and learned much over his forty(?) year career. Fiction: Saturn Run, by John Sandford. Very exciting, great characters, science fiction with great science. I would call it a modern science fiction novel. Very Refreshing. Science/history/cool: Sunburst and Luminary, by…
on “Ask HN: What is the best book you read in 2020?” ↗Saturn Run, is a really interesting and fun book - by John Sandford. I highly recommend it, as a successful modern science fiction book. That topic is really well covered, with engineers solving all sorts of problems,…
on “Akin's Laws of Spacecraft Design” ↗if you want some interesting sci fi. I've just finished "the Saturn Run" by John Sandford and Ctein. One of those stories like Portal 1/2 I'd like to forget and be able re-experience for the first time
on “Liu Cixin's Technologies of the Future” ↗You're joking but this reminds me of a hard sci-fi novel I read recently, Saturn Run[0]. One of the minor worldbuilding trivia there is that adhesives seem to be way overused to fix and modify things in space. (The book also features the coolest design for a radiator I've ever seen anywhere.)…
on “One hull crack located in ISS, another one suspected” ↗A fun fiction novel by John Sanford, Saturn Run, presents a neat solution for the problem of heat dissipation, in space. Fun read.
on “UK backs Rolls-Royce project to build a nuclear reactor on the moon” ↗…mesh with our astronomical observations. The book that came to mind is a classic, "The Mote in God's Eye." Though there are dozens of delightful variations and imaginative situations, such as with "The Saturn Run." There's an entire spectrum that's been imagined and explored.
on “Odds of communicating with 36 other possible intelligent civilizations are small” ↗Reminds me of the book Saturn Run, by John Sanford - which has a lot of effort put into the technology and radiation of heat in their space ship. Fun science fiction book.
on “NASA's Voyager Found a 30k-50k Kelvin "Wall" at the Edge of Solar System” ↗…he does, I'm going along for the journey. (Honorable mention: Alien Clay. Dishonorable mention: Service Model.) Eric Flint's "Fenrir" was a fun BDO near-future space adventure. (As was John Sanford's Saturn Run, but that wasn't a 2025 book I read.)
on “Ask HN: What did you read in 2025?” ↗The book Saturn Run has an interesting design utilized for a spaceship.
on “Starcloud” ↗Saturn Run by John Sandford and Ctein (2015) has a appendix where the authors runs down the science behind their space science (and calls out something like Star Treky science explaining). I read this after the…
