I've been to the Titanic in a yellow submarine and the North Pole in a Russian nuclear ice breaker.

Having left the water planet, with all that water brings to Earth in terms of colour and abudance life, the absence of water and atmosphere on the desolate surface of the Moon gives rise to a stark contrast.
