Uncharted Depths

Two and a half hours down, his thrusters were dead and his submarine was spinning in a circle on the floor of the ocean. The only way back up was one system James Cameron had never been able to fully test...

In 2012, James Cameron became the first person ever to reach the bottom of the Mariana Trench alone, nearly 11 km down (about 35,787 feet). This is the story of everything that went wrong at the bottom, and the almost absurdly simple piece of engineering that carried him home.

Uncharted Depths

In 1960, two men dropped for nearly five hours into the deepest place on the planet, heard something crack in the dark, and kept going anyway. What one of them saw at the bottom is still being argued about more than sixty years later.

This is the story of the bathyscaphe Trieste: the day Jacques Piccard and Don Walsh became the first people ever to reach the bottom of the Challenger Deep in the Mariana Trench, nearly eleven kilometres down.
