Book Recommendation: Rendezvous with Rama
If you are looking for something to read or listen to then I would like to recommend the 1973 book Rendezvous with Rama by the late author Arthur C. Clarke. Set around 100 years in the future it encompasses the discover and exploration of what first appears to be an asteroid, which is later found to be much more.
While it may be considered cheating to book lovers, I listened to an abridged audio book which provided a very interesting two hour listen.
Outside of the above Rendezvous with Rama is also available in book, ebook, or unabridged audiobook form in a number of places.
