Deep Space Observatory - Keck, Hawaii

Richard Hammond journeys to discover the startling engineering connections behind the Keck Observatory, which has seen further into the universe than any other telescope on earth.

He reveals that the observatory owes its incredible design to an ancient Greek ritual, an early twentieth-century Russian inventor, an American Civil War general, a breakthrough in aerial reconnaissance and an attempt to cure yellow fever.

Hidden in its DNA he finds an ancient technique for lighting a flame, a weird-sounding musical instrument, a sandblaster, a Korean spy plane and a refrigerator.
