Project Hail Mary, The Martian, Contact. Somewhat in line with a better future mentioned in the essay, The Ministry for the Future and the Mars trilogy by Kim Stanley Robinson posit some solutions to some big technological challenges with a lot of time with each side in the political debate, though whether one finds it optimistic lies with the reader.
I was as disappointed as everbody else by Artemis, but Project Hail Mary was a great return to form and a great Space MacGyver Procedura. Definitely left me fired up and feeling positive as well. I really appreciate just the joy in knowledge that Weir's books revel in.
I might just be vulnerable to maudlin storylines but Project Hail Mary made me tear up a couple of times. The audiobook adaptation is tremendous with sound effects, too.
