On 23 January 1960 the bathyscaphe Trieste, carrying Swiss Jacques Piccard and American Don Walsh, reached the floor of the Challenger Deep at about 10,916 m. It was designed by the pilot's father, Auguste Piccard. No one went back for 52 years, until director James Cameron in 2012.

Until 2012, only two people had been to the bottom of the Mariana Trench, six times fewer than had walked on the Moon. Piccard and Walsh dived in 1960; twelve astronauts walked on the Moon in 1969–1972. Share →
