The mother ship for a new Chinese deep-sea manned submersible has successfully completed a scientific expedition journey and is now back home.
The 94-meter Tansuo-1, with 60 scientific researchers from the Chinese Academy of Sciences on board, finished 84 missions during its 52-day voyage.
It set out from south China's city of Sanya in June and reached the deepest part of the ocean in the world, the Mariana Trench in west Pacific.
Details of all the samples and data it collected will soon be made public.
