Jiaolong dives to a depth of nearly 7,000 meters, does anyone know how deep a human submersible is?

According to the 25th channel, the famous American director James Cameron recently drove a solo submersible to the bottom of the Challenger Abyss, the deepest part of the world's oceans. He has now completed his dive and is back at the surface.

Cameron's partner in the diving challenge, National Geographic, confirmed that Cameron had reached 10,898 meters, the ultimate depth for humans to dive into the ocean. Cameron was the third person to reach the bottom of the deep trench near **, and the first to dive alone.

It is reported that Cameron is 57 years old this year, he insists on running every day and practicing yoga to improve the flexibility of his body to adapt to the narrow space design of the deep submersible. In addition to this, he is also actively learning about the ocean.

The deepest ocean dive.

American "Trieste" (10,916 meters).

Depth: 10,916 m (nearly 11 km).

Underwater duration: 20 minutes.

On January 23, 1960, Picard and U.S. Navy Officer Don Walsh traveled aboard a deep-sea submersible named the USS Trieste to the Mariana Trench, the deepest point in the South Pacific, and reached a point nearly 11 kilometers below sea level (10,916 meters). This is the deepest place under the sea that man has ever reached. However, due to the pressure on the seabed, a slight crack appeared in a 19-centimeter-thick porthole of the deep-sea submersible, and Piccard had to rush to the surface after spending 20 minutes at the bottom of the sea.

In March 2012, the famous American director James Cameron took the submarine "Deep Sea Challenger" alone, diving nearly 11,000 meters to explore the bottom of the Mariana Trench.

The Jiaolong manned submersible is a manned submersible designed and integrated by China, and it is also a major research project in the 863 Program. From May to July 2010, the Jiaolong manned submersible carried out several diving missions in the South China Sea, reaching a maximum depth of 7,020 meters.

In 2002, China's Ministry of Science and Technology listed the development of deep-sea manned submersibles as a major special project of the National High-tech Research and Development Program (863 Program), and started the self-design and integrated development of the Jiaolong manned deep-sea submersible. From 2009 to 2012, the 1000-meter, 3000-meter, 5000-meter and 7000-meter sea trials were successfully achieved.

In June 2012, in the Mariana Trench, it set a Chinese manned deep diving record of 7,062 meters, which is also the world's largest diving depth record for similar operational submersibles.

Technological advantages. 1. It has the largest diving depth of 7,000 meters in the same type in the world, which means that the submersible can be used in the vast sea area that occupies the world's ocean area.

2. It has a stable hovering for the operation target, which provides a reliable guarantee for the submersible to complete high-precision operation tasks.

3. It has advanced underwater acoustic communication and seabed micromorphology detection capabilities, which can transmit images and voices at high speed and detect small targets on the seabed.

4. Equipped with a variety of high performance to ensure that the manned submersible can complete complex tasks such as fidelity sampling and submersible drilling and coring under special marine environment or submarine geological conditions.

China's Jiaolong submarine dives to a maximum depth of 7,062 meters.

From May to July 2010, Jiaolong carried out several diving missions in the South China Sea, reaching a maximum depth of 3,759 meters. On July 26, 2011, the Jiaolong manned submersible reached a depth of 5,057 meters. On June 27, 2012, the metre was reached.

On March 17, 2015, Jiaolong officially berthed at the home port at the national deep-sea base at 36°20 120°43.

Note: Jiaolong is long, wide and high, weighs no more than 22 tons in air, does not include the weight of the crew, has a payload of 220 kilograms, is designed to dive to a depth of 7,000 meters, can carry one submarine and two scientists, and can explore the sea area covering the world's oceans, although it is still a considerable distance from the bottom of the Mariana Trench, the deepest known part of the Earth's oceans, at 10,911 meters.

The project began in 2002 and was included in the 863 Program by the Ministry of Science and Technology of the People's Republic of China. A total of about 100 scientific research institutions and enterprises, including the Shenyang Institute of Automation, Chinese Academy of Sciences, participated in its research and development work. The chief designer of Jiaolong is Xu Jinnan, an expert in deep diving technology in China.

Jiaolong currently has a maximum diving depth of 7,062 meters and a maximum working design depth of 7,000 meters.

After the successful delivery of Jiaolong, from 2009 to 2012, Jiaolong successively achieved 1000-meter, 3000-meter, 5000-meter and 7000-meter sea trials. The dive to 7,000 meters shows the maturity of the integrated technology of the Jiaolong manned submersible, marking that China's deep-sea submersible has become one of the frontiers and commanding heights of marine scientific investigation.

Since 2013, Jiaolong has officially entered the experimental application stage. On June 13, 2017, local time, Jiaolong successfully completed the last dive of the third voyage preparation and clearing section of Dayang 38 voyage, marking the successful completion of all the diving tasks of the experimental application voyage.

So far, Jiaolong has successfully dived 158 times. The deep sea is rich in resources and is the blue space for the future development of mankind. As the only manned submersible capable of diving 7,000 meters in China, Jiaolong plays an important role in exploring the deep sea.

The significance of the successful development of Jiaolong

1. It can carry out fine measurement of the topography and landform of the community, obtain nodule samples, water samples, sediment samples, and biological samples at fixed points, and evaluate them by taking pictures and comparing the coverage rate of polymetallic nodules, etc., and can also measure the temperature of the polymetallic sulfide hydrothermal nozzle, collect water samples around the hydrothermal nozzle, and store hydrothermal water samples in fidelity, etc., explore cobalt crust resources, use submersible drills to carry out core sampling operations, and measure the coverage and thickness of cobalt crust deposits.

2. China is the fifth country in the world after the United States, France, Russia and Japan to master the technology of large-depth manned deep diving. Among the world's manned submersibles, China's Jiaolong belongs to the first echelon. At present, there are about 90 manned submersibles of various types in use in the world, of which only 12 have dived to a depth of more than 1,000 meters, and the number of deeper submersibles is even less.
