The world mourns the passing of a great man.  Science fiction author, scientist, and visionary, Dr. Clarke was the guiding light of the space travel movement.  He was writer of the powerful and controversial motion picture “2001: A Space Odyssey.” He wrote hundreds of fiction and non-fiction books and essays that advocated space travel and a positive future. He was also a believer in the emerging commercial space travel industry, including space tourism.  We shall miss you!
