Almost everyone knows about the New Horizons space probe that was sent on a 10 ten year mission to the dwarf-planet Pluto, more than 3 billion miles away from Earth. On July 14, 2015, New Horizons made it epic closest approach to the mysterious body in the void. The NOVA produced documentary “Chasing Pluto” is a record of this event and just what we have learnt from a place that has had no visitors for billions of years.
