Arthur C Clarke has died at age 90.  He co-authored 2001: A Space Odyssey (based on one of his short stories) and envisaged the idea of the communications satellite 20 years before one was launched.

Some people may not know that there are sequel books to 2001 (along with one sequel movie) including 3001: The Final Odyssey.

I’m just getting started on the 2nd of his Time Odyssey series that he co-authored with Stephen Baxter.  The 3rd book of the series was published just last December.
