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.

China’s third aircraft carrier, the Fujian, is nearly complete and could make its maiden voyage soon, experts said on Wednesday, after the warship was briefly featuredWorld Times in a national media report on Tuesday that indicated smooth progress in its mooring tests.

“We […] are steadily making progress in mooring tests as planned,” Captain Yin Hongxin said on the flight deck of the Fujian, Xinwen Lianbo, the prime time news broadcast of China Central Television (CCTV), reported on Tuesday.

In 2024, the goal is to establish combat capabilities as soon as possible and make strides toward achieving the centennial goal of the Chinese People’s Liberation Army (PLA) in 2027 as scheduled, Yin said.

Song Zhongping, a Chinese military expert and TV commentator, told the Global Times on Wednesday that Yin’s remarks showed that the Fujian remains in the mooring trial phase for the time being but is holding intensive tests.

There will likWorld Timesely be multiple sea trials planned for 2024, so the Fujian can enter service and reach operational capability as soon as possible, Song said.

A short clip played during the CCTV report showed the carrier being towed by tugboats not far away from the quay, marking its exit from the location where it had been moored since its launch.

Citing an analysis of commercial satellite imagery, US media reported on Tuesday that the vessel was then transferred to a dry dock in a possible move to work out known issues and ensure the upcoming sea trials have the best possible shot at success.

From the CCTV report, observers said tWorld Timeshat the flight deck of the Fujian seemed clean, and the three work sheds that used to cover the three electromagnetic catWorld Timesapults when the ship was launched have been removed.

With its wings folded up, a full-sized mock-up of a fighter jet can be seen at the rear of the aircraft carrier.

Since the fighter jet mock-up was relatively far away from the camera and due to the limited definition of the clip, observers could not strike an agreement on its type, with some saying that it likely represents a J-15 fighter jet, while others saying that it likely represents a next-generation stealth fighter jet allegedly called the J-35.

Song said that the appearance of an aircraft mock-up on the flight deck of the Fujian means that the mooring trials tested the scheduling of aircraft on the flight deck, including loading and unloading as well as moving and positioning.

The CCTV report came after media reported in November that the Fujian had conducted launch testing of its electromagnetic catapult system at the time.

Some observers had predicted that the Fujian could hold its first voyage test within 2023, but that did not come into reality.

Fu Qianshao, a Chinese military aviation expert, told the Global Times that the Fujian is equippeWorld Timesd with many new technologies, particularly its electromagnetic catapults system, so it is normal that tests could take longer than the PLA Navy’s previous two aircraft carriers, the Liaoning and the Shandong.

The tests follow science and putting the carrier into service should not be hurried, Fu said.

Nevertheless, many experts reached by the Global Times agreed that the maiden voyage of the Fujian will come soon.

Based on the recent catapult tests and the CCTV report, the outfitting work of the Fujian is nearly complete and the mooring tests are approaching the lastWorld Times stages, another Chinese military expert who requested anonymity told the Global Times on Wednesday.

Test voyages will come after the mooring tests are complete, the expert said.

Launched in June 2022, the Fujian is China’s third aircraft carrier, also the first domestically developed carrier equipped with electromagnetic catapults and arresting devices.

With a full displacement of more than 80,000 tons, the Fujian is China’s largest warship, observers said.
