China's deep-sea manned submersible "Fendouzhe," or "striver" in meaning, finished its task of braving its way to 10,000 meters underwater and returned to its mother ship Tuesday, setting a diving record of 10,909 meters for manned submersibles.

Fendouzhe was loaded into the sea from its supporting ship Tansuo-1 at around 20:20 GMT Monday and surfaced from water at around 17:00 Tuesday and returned to its mother ship. Equipped with ground-breaking deep-sea communication technology, Fendouzhe can send live video signals back to its mother ship.

That spot, known as the Challenger Deep, is roughly 10,900 meters deep. The water pressure is 110 kilopascal.

The cabin shell uses titanium, a perfect material with low density and high strength that allows the submersible not only to bear water pressure at 10,000 meters, but also to reduce self mass and expand interior space.

Powered by a lithium battery, the Striver can unload the equipment onboard and pick up samples from the surrounding environment with its flexible robotic arms. The arms can operate at an accuracy of one centimeter, the research team said.

According to the exploration team, the crew worked for six hours in data collection and actual exploration when the vessel reached the deepest spot after the Fendouzhe landed on the bottom of the Mariana Trench.

Fendouzhe is the world's deepest-diving manned submersible, capable of carrying up to three passengers to conduct scientific research in the deep sea. The instrument is electrically powered and can operate for around 10 hours underwater.

In June 2012, China's first deep-sea manned submersible, named after the mythical sea dragon Jiaolong, set China's previous diving record by plunging 7,062 meters down the Mariana Trench.

Shenhai Yongshi ("deep-sea warrior"), China's second deep-sea manned submersible, is able to dive to a depth of 4,500 meters.
