Battling against the establishment, Harrison stood alone in pursuit of his solution and the £20,000 reward offered by Parliament.

Have you ever wondered what it would be like to watch a double sunset on Tatooine, stand among the sand dunes of Arrakis or gaze at the gas-giant planet Polyphemus from the moon Pandora?
