The Apollo Moon Programme has been called the last optimistic act of the twentieth century.
Over a strange three-year period between 1969 and 1972,
twelve men made the longest and most eccentric of all journeys and all were indelibly marked by it.
Of those astronauts who walked on the Moon only nine are still alive.
One day in the near future there will be none:
no one on Earth will have known the giddy thrill of gazing back at us from another world.
In Moondust, Andrew Smith sets out to find and interview the remaining Moonwalkers
in order to learn how their lives, and ours, were changed by this surreal adventure for ever.
