2. Manned submersible Fendouzhe sets diving record

On Dec 5, China's manned submersible Fendouzhe (Striver) returned to a port in Sanya, Hainan province, from a 53-day expedition. As of December, it has completed 21 dives with a depth of over 10,000 meters, carrying 27 scientists to the deepest parts of oceans. Both the figures are the highest in the world.

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.
