Chinese Submarine Breaks Deepest-Dive Record in Mariana Trench

A Chinese submarine descended to 6,908 meters (22,600 feet) in the Mariana Trench today, breaking the record for the nation’s deepest dive a day after astronauts performed China’s first manned space docking.

The Jiaolong submersible began the descent in the trench, located in the Pacific Ocean, at 7 a.m. today and will try more dives with the goal of reaching 7,000 meters, the Xinhua News Agency said. The Jialong carries a crew of three.

An earlier dive attempt was aborted because of a communications problem. A leaking hydraulic pipe was also fixed, Xinhua said.

The dive occurred less than 24 hours after three Chinese astronauts, including China’s first woman in space, docked their spacecraft with an orbiting Tiangong space module. The docking was broadcast live on state television.
