Like Sir Arthur, Pete Worden was 'in at the beginning' of countless courageous departures -- among them the Strategic Defense Initiative, the revitalization of civil space exploration and Earth monitoring, and programs to get mankind at a working distance from Near Earth ObjectsNASA scientist gets Arthur C.

Sri Lankabhimanya Sir Arthur Charles Clarke, CBE, FRAS (16 December 1917 – 19 March 2008) was a British science fiction author, inventor, and futurist, most famous for the novel 2001: A Space Odyssey, written in parallel with the script for the eponymous film, co-written with film-director Stanley Kubrick; and as a host and commentator in the British television series Mysterious World. For many years, Robert A. Heinlein, Isaac Asimov, and Arthur C. Clarke were known as the "Big Three" of science fiction.
Clarke served in the Royal Air Force as a radar instructor and technician from 1941–1946. He proposed a satellite communication system in 1945 which won him the Franklin Institute Stuart Ballantine Gold Medal in 1963. He was the chairman of the British Interplanetary Society from 1947–1950 and again in 1953.
Clarke emigrated to Sri Lanka in 1956 largely to pursue his interest in scuba diving, and lived there until his death. He was knighted by Queen Elizabeth II in 1998, and was awarded Sri Lanka's highest civil honour, Sri Lankabhimanya, in 2005.
