This was a really good collection. Almost every story in the book was about space and rockets, although there was a bit of variation. All the stories were well written, Bradbury seems to focus on the characters first and foremost, which makes it easy to connect with the stories.
It should also be noted that this is not a light book. A lot of the stories are very, very dark, and some are disturbing. There is a sprinkling of upbeat stories mixed in which keeps it from being too much, but it's pretty intense. It's small and short, but definitely not a light read!
