Tonight's special Intrepid event was the book launch of "Artemis" - the new novel by Andy Weir, author of The Martian. He wax interviewed by Jeffrey Kluger, author of Apollo 8 and Apollo 13. Both men discussed their interest in science and accurate details in their books. Mr Weir has published on-line some very interesting papers on his research for his new book. Lively questions were posed by the audience. A fun night. I'm a big sci-fi fan.
