Quick Summary

The Deepsea Challenger is a submersible that was designed and piloted by filmmaker and explorer James Cameron for a solo dive to the Challenger Deep, the deepest known point in Earth's oceans.12

On March 26, 2012, Cameron reached a depth of 35,756 feet (10,898 meters) in the Deepsea Challenger, setting a new world record for a solo descent. This submersible was a significant advancement in deep-sea exploration, enabling humans to reach extreme ocean depths. The Challenger Deep itself was first explored in 1960 by Jacques Piccard and Don Walsh in the bathyscaphe Trieste. The Glomar Challenger was a different vessel, an oceanographic drilling ship active from 1968 to 1983, which played a crucial role in supporting the theory of plate tectonics.123
