INNER SPACE: Texas explorer completes deepest ocean dive in history.

A Dallas-based explorer has set a record for the deepest dive ever made in a submersible — in the world’s deepest ocean trench, his organization announced Monday.

Victor Vescovo reached a depth of 35,853 feet on April 28 during a dive to the bottom of Challenger Deep in the Mariana Trench, the deepest known point on earth. The dive was 52 feet deeper than any previous manned dive, Vescovo’s Five Deeps Expedition said.

The last visit to Challenger Deep also set a depth record at 35,787 feet. That journey was made by filmmaker James Cameron in 2012.

During the April 28-May 5 expedition to the Mariana Trench, the team also completed a dive to the bottom of Sirena Deep, about 128 miles away from Challenger Deep. The team spent hours at the bottom of the ocean at these locations, collecting samples, including the deepest piece of mantle rock ever collected.

Cool.
