Just a few weeks back in an article i had mentioned Arthur Clarke commenting on the Orion. I woke up today morning with the news that the celebrated thinker, novelist, writer had passed away in his Sri Lankan home due to heart failure.
I have read quite a few of his fictional works. I started reading his works at the age of 10. He thought ahead of the present generation. His famous works included 2001:A Space Odyssey. After military service in the great war Clarke wrote a lot of fictional stories and technical papers. His writings he Exploration of Space (1951) and The Promise of Space (1968 ) made him very famous for the concept of a geostationary satellite. The International Astronomical Union recognizes a geostationary satellite as a Clarke orbit. The idea of space elevator is also associated with him. I would not count on his achievements anymore. His detailed biography can be found here.
This is sad news, though not unexpected. He had recorded a good bye message for friends on his 90th birthday. Maybe he saw it coming. A legend is no more between us.
