If you liked The Martian and Project Hail Mary, two books I cannot recommend enough are Daniel Suarez' Delta-V and Critical Mass. Highly technical focused hard-sci-fi about asteroid mining and human dynamics in high-risk envrionments. I can't vouch for the absolute factual correctness, but it has an appendix listing the papers the author indirectly references for the book.

Delta-V is also described as a "Technothriller" - i.e. in the grey area between action thriller and sci-fi, where the tech is current and cutting-edge, or possibly an inch beyond. I liked the first book, will try the second some time soon.

I really enjoyed his Daemon novel, and I think it would appeal to the HN crowd. Interesting intersection of code and the real world, and it is set more-or-less in the current time.

Daemon is the first of a trilogy. The remaining two books are good, but not quite as good IMO.

Do you know any other hard sci-fi books like this? I loved the Delta-V series, and have been looking for hard sci-fi like it ever since.
