Good Book To Read After Project Hail Mary?

Hello!

I just watched the movie last week and finished reading the book yesterday. I am looking for book recommendations that feel similar to Project Hail Mary. I have a few things I am looking for specifically that are listed below but accept recommendations even if they don't fulfill all of them!

1. Science fiction (does not have to involve aliens but I would prefer it involved space travel).

2. A protagonist older than early twenties.

3. Romance is either a subplot or not involved at all.

4. Logical science (does not have to be realistic, just make logical sense for the world it's in).

5. Preferably hopecore (I do not mind scenes with angst but I want to stray away from distopia and existential dread filled stories if possible).

6. Have an audiobook version available.
