A novel that proposes an idea about how the human race might have begun and where it might be headed...given a little help from out there. A colaboration of ideas with director Stanley Kubrick in the late 1960's it begins at "the dawn of man" and then leaps to the year 2001 where a mission to Saturn (Jupiter in the film) is mounted to try and answer questions raised by the discovery of an ancient artifact dug up on the moon. Though not particularly fast paced, the science is good, and there are a few hair raising events. There are also interesting speculations about the future, such as the space shuttle, and a device eerily similar to an iPad. Leaving plenty of room for contemplation and the appreciation for the inevitable trials of space travel, this is one of the truly landmark pieces of hard science fiction.
SF, especially, hard SF, has always tackled grown up questions.
Here are a few I have recently re-read:
The Dispossessed by Ursula K. Le Guin, Saturn's Children by Charles Stross, Engines Of Light by Ken McLeod, 2001 by Arthur C. Clarke, Robots of Dawn, etc. by Isaac Asimov.
Then when Clarke did the book for 2010 he retcon'd it to match the movie.
That being said, I think the onscreen evidence for Clarke's version is compelling. Most notably, it solves the mystery highlighted by the article as to why HAL didn't kill Bowman on the first EVA: If the computer could have engineered a plausibly innocent loss of contact with Mission Control, he could have acted freely to preserve both the astronauts' ignorance and the success of the mission without worry of being contradicted by the ground-based twin computer (which he surely knew would eventually diverge from his decision-making, having not been informed about the Monolith).
Once the astronauts were told of the divergence and took it seriously enough for their discussion in the pod, HAL had no remaining options.
