quite clearly

How inappropriate to call this planet Earth when it is quite clearly Ocean.
~ Sir Arthur C. Clarke

Grand Master Science – Fiction author, Sir Arthur C. Clark was born to be a visionary in the public eye, he was a Sagittarius, with Sun conjunct North Node of destiny.

He was a futurist with Venus and Uranus in Aquarius  – Venus trine Jupiter in Gemini.  He had a knack for creative ideas, was fond of exploring, (he was an avid scuba diver) and he was an optimistic idea man with a mind bursting with possibilities.

In 1945, his paper the “Extra-terrestrial Relays” he set out the principles of satellite communication with satellites in geostationary orbits  – a speculation realized 25 years later. During the evolution of his discovery, he worked with scientists and engineers in the USA in the development of spacecraft and launch systems, and addressed the United Nations during their deliberations on the Peaceful Uses of Outer Space.
Today, the geostationary orbit at 36,000 kilometers  above the equator is named The Clarke Orbit by the International Astronomical Union.

He had Saturn conjunct Neptune in Leo, lending a studied, reasoned approach to his creative writing of the cosmos.  He was fully aware the science fiction he wrote could very well one day become science fact.  Saturn and Neptune in opposition to Venus and Uranus indicates his balance between the mystical properties of fiction built from fact and blended into the future.

Mars in Virgo trine a Moon Mercury conjunction in Capricorn.    He was all about diligent methodical and accurate communication, obviously.  It was his idea to have satellites ‘hop’ signals across space aka satellite relays.
In World War II he served in the Royal Air Force as a radar specialist, working in early warning systems.

Pluto in Cancer opposite Mercury and Moon in Capricorn, he expressed ‘home’ in his novels as far from his doorstep as he could get, and led all his readers to envision new horizons as well.
He was building the future through science – fiction writing.
