According to media reports, in October this year, the Chinese "Struggle" manned submersible successfully sat on the bottom of the Mariana Trench, reaching a depth of 10,909 meters. The successful exploration of the
"Struggle" means that my country has made a new breakthrough in the field of scientific research. It is understood that during the time of the "Struggle" undersea observation, the three divers saw a lot of volume comparisons on the bottom of the sea. Small transparent sea cucumber. In addition to discovering sea cucumbers, the Struggle will continue to search for creatures with observational value.
A new breakthrough in China's deep-sea field
It is understood that before the Chinese Struggle entered the Mariana Trench, the deepest detection record in human history was 10,911 meters, which was held by the United States.
A deep-sea probe in Japan before, found a fish that is known to live in the deepest part of the ocean at a depth of more than 8,000 meters in the Mariana Trench.
However, in the late 1990s, the Japanese "Trench" deep submersible in the Mariana Trench captured white plastic garbage left by humans at a depth of more than 10,000 meters.
Chinese researchers have also found many plastic residues deep in the Mariana Trench.
Because only some sea cucumbers and plastic left by humans can be found in the depths of the ocean, the United States' exploration of the deep sea seems very hasty.
But unlike the United States, China has never stopped exploring the depths of the ocean. In addition to the Struggle, China has a large number of unmanned submersibles that have been placed on the seabed for deep-sea exploration. The proper layout of
has given China more say in the deep-sea field, and made the United States jealous.
China currently combines manned submersibles and unmanned submersibles, giving China the ability to independently study 10,000 meters of deep sea. Among them, the submersible is very complicated.
and the buoyancy of the deep submersible is also very particular. During the buoyancy process, the buoyant material outside the hull will open to provide a balloon-like structure for the hull to ensure that the hull returns to the surface safely.
Major breakthroughs in the aerospace field
In addition to the deep-sea field, China’s development in the aerospace field has also attracted worldwide attention. China’s Sky Eye system is well-known in the world. The independently developed Beidou navigation system has replaced the previous GPS.
The Beidou system independently developed by China can realize independent operation, realize global navigation and provide more accurate positioning services for customers around the world.
and Beidou navigation satellites have also added a communication function. This function not only allows users to know their location, but also reports their location to others in the form of text messages. Although the function of
looks very useless in areas covered by the signal, in some very special circumstances, such as deep mountains or deserts, once an accident occurs, the Beidou system can send information to the outside world in time to obtain Rescue.
