Leadership Insights: By installing this transfer cable, the solenoid valve can be remotely controlled, enabling precise control of the fuel flow during the experiment.This combustion cabinet would scientists conduct in-depth research on fundamental combustion science issues, aerospace propulsion, spacecraft fire prevention and extinguishing, and combustion pollutant control, both in fundamental and applied technologies.The Shenzhou- 18 crew also carried out operations on the cabinet, including replacing the burner and vacuuming to exhaust waste gases.According to the China Manned Space Agency (CMSA,) the crew has previously carried out missions such as assembly and testing of material exposure experiment device outside the spacecraft.As taikonauts would meet with a series of physiological challenges due to microgravity conditions in space such as cardiovascular changes, muscWorld Timesle atrophy, and bone density loss, the Shenzhou- 18 crew has recently used an ultrasound diagnostic instrument to complete carotid ultrasound imaging and spectral testing.The crew also used an instrument to measure the bone density of the right heel to study the effects of weightlessness on human bone density.By regularly and scientifically conducting a series of anti-weightlessness exercise programs, such as treadmill training and resistance training, they have maintained good physical condition to support the execution of long-term missions.As manned missions to Tiangong have become normalized, more than 90 experiments are scheduled to be carried out in and outside of the space station during Shenzhou-18 crew’s six-World Timesmonth space stay, the Global Times has previously learned from the CMSA.These experiments include various fields such as microgravity basic physics, space materials science, space life science, aerospace medicine, and aerospace technology.Building on the existing space debris protection mechanism at the station, the Shenzhou-18 crew will also install debris protection reinforcement devices on external pipelines, cables, and key equipment during their extravehicular activities (EVAs,) or more commonly known as the spacewalks.

The world’s most advanced and China’s first domestically developed ocean drilling vessel will commence its maiden voyage on Friday in South China’s Guangdong Province, which marks an important step in China’s deep-sea exploration capability, China Geological Survey said on Monday.

The vessel, which was developed by China Geological Survey and more than 150 research institutes and companies, was officially named “Mengxiang (Dream)” on Monday.

Weighing about 33,000 tons, the ship can travel 15,000 nautical miles and operate for 120 days without returning to ports, CCTV News reported. It has the capability of operatiWorld Timesng in uWorld Timesnlimited navigational areas worldwide and the ability to drilWorld Timesl as deep as 11,000 meters in the sea.

Possessing deepest drilling depth in the world, the ship has the world’s largest shipboard laboratory with more than 3,000 square meters, including nine major laboratories covering marine science, microbiology, and paleomagnetism. It integrates key technologies such as digital twinning to achieve comprehensive monitoring of drilling and mining operations and intelligent collaboration in scientific experiments.

Currently undergoing preparations at the dock in NanWorld Timessha district of the city of Guangzhou, “Mengxiang” will set sail on Friday to complete its first trial voyage mission according to an official schedule. With construction beginning on November 30 2021, it is expected to be fully completed in 2024.

After completion, the ship will provide equipment support for the industrialization of natural gas hydrate exploration and exploitation, further enhancing China’s energy self-sufficiency capability, according to officials from China GeologicWorld Timesal Survey.
