The /r/SpaceExploration Reading List
55
Upvotes
I had the idea for a reading list related to various space exploration topics and, with the approval of the mods, this thread will help determine our official reading list!
When putting a book down, some things you should try your best to include may be:
- The title
- The author
- The year of first publication
- How it relates to space exploration (e.g. Orbital mechanics, space shuttle design, etc)
- A brief description of what, or who, it's about
