Chinese Manned Submersible Reaches Deepest Part of Mariana Trench

China shared livestream footage of its latest submersible safely parked at the bottom of the Pacific Mariana Trench on Friday.

The vessel, Fendouzhe, or Striver, went down 35,790 feet (10,909 meters) with three scientists on board, stated Chinese news agency CCTV (in Mandarin).

Footage of the impressive descent has been shared, with images of dark green and blue hues, floating sediment, and rocks on the seabed circulating. 


Last week's descent was just shy of beating the deepest dive world record, which was set by the American explorer, Victor Vescovo, in 2019 reaching a depth of 35,853 feet (10,927 meters), reports Science Times.

Earlier this month, Fendouzhe successfully landed at the deepest known section of the Mariana Trench — the Challenger Deep — after having carried out a number of successful dives, says

Friday's descent marked the first-ever livestreaming of a submersible's drop into the world's deepest oceanic trench. 

The green and white submersible is equipped with robotic arms to collect biological samples, as well as sonar eyes to identify its surroundings by using sound waves. To keep it balanced, scientists have placed buoyant materials on it. 

Our oceans are still a huge mystery to scientists, so Fendouzhe's mission is to shed more light on scientific exploration of our deep oceans, explained Ye Cong, the vessel's designer, to Science Times.

The Chinese scientists working on the project remain humble, however, as they state that one successful touchdown does not count as a successful mission— there have to be at least a couple more descents.
