In its earliest days, science fiction was almost always about space travel. Back in the bad old days of the 1920s and 30s, when the genre was gathering steam in the American pulps, heavily muscled spacemen and bug-eyed alien monsters predominated. It was only when John W. Campbell Jr. took on the editorship of Astounding Stories in 1937 and began to recruit as contributors the likes of Isaac Asimov and Robert A. Heinlein that sci-fi started turning respectable (in its own eyes, if in few others at the time).

Science fiction . . . or “speculative fiction?”
Later, widely acclaimed writers such as Kurt Vonnegut, Margaret Atwood, and Doris Lessing began writing science fiction even though they denied that was what they were doing. And that was when critics started referring to the genre as “speculative fiction” while casting aspersions on mainstream efforts in the field. But that was a mistake. By then—the 1950s and 60s—the best science fiction authors were producing stories that could stand up to the best that the “literary” critics could point to . . . if only they weren’t looking down their noses with such disdain. And that is most assuredly still the case today.
Are space operas really about space travel?
Nowadays, space travel is merely one of a number of themes commonly explored in science fiction. While novels of that ilk still frequently appear, they’re matched by equal numbers of stories about artificial intelligence and robotics, dystopian visions of the future, speculation about time travel, and other themes. Thus, although I’ve read hundreds of science fiction novels and nonfiction books about science and technology, I find that only a few dozen are truly about space travel. Admittedly, thousands of space operas have been sold which, in my view, are only tangentially about space travel. They’re . . . well, the literary descendants of the old “horse operas” from the era of the pulps. And they rarely give any sense of what the experience of living and working in space might actually be like.
Now, I love good space operas. I’m a particular fan of the long-running Vorkosigan Saga by Lois McMaster Bujold, who has won numerous literary awards for the books. (You can find my reviews of those stories at The pleasures of reading the complete Vorkosigan Saga.) But I don’t regard these novels as casting any light on the reality of space travel, so I’m not listing them here.
Good books about space travel, including both nonfiction and fiction
The lists that follow include only those individual books that directly concern space travel. In several cases, trilogies or longer series of novels include only one such book, and that’s the only one I’m listing here. Also, I’m including only those books I’ve awarded scores of @@@@ or @@@@@ (4 or 5 out of 5). Numerous others that received lower scores don’t appear here.
I’ve listed five nonfiction books first. The rest are novels. In both lists, titles appear in alphabetical order by the authors’s last names.
