[CCTV News]The Shenzhou 18 launches into space and the scientific exploration of the dream space continues to move forward_Guangming.com

On April 25, 2024, the Shenzhou 18 manned spacecraft was launched, and astronauts Ye Guangfu, Li Cong, and Li Guangsu began their space journey.

Shenzhou 18 manned spacecraft launched

The Long March 2F carrier rocket successfully launched the Shenzhou 18th crew into orbit. The launch mission was a complete success. The Shenzhou 17th and Shenzhou 18th astronaut crews successfully “reunited” at the Chinese Space Station. People are very fond of the Shenzhou 18th mission. The mission that the No. 1 will perform is full of expectations. While in orbit, the crew of Shenzhou 18 will carry out a number of scientific experiments, including implementing the country’s first on-orbit aquatic ecological research project. “Space fish farming” is expected to be realized on the Chinese Space Station; conducting 2 to 3 extravehicular activities, and conducting Install debris protection and reinforcement devices on external pipelines, cables and key equipment. In addition, passive radiation refrigeration materials, optical fiber materials and optical film materials are also planned to be installed by astronauts in the material extravehicular exposure experiment device in May this year and then leave the cabin to conduct a new round of exposure experiments.

Previously, the Shenzhou 17 astronaut crew composed of Tang Hongbo, Tang Shengjie, and Jiang Xinlin had successfully completed two extravehicular missions while in orbit, completed the maintenance mission of the extravehicular facilities of the orbiting spacecraft for the first time, and also successfully retrieved the first batch of There are 407 material samples for extravehicular exposure experiments, including metals and non-metals. These samples will then be returned to the ground with the Shenzhou spacecraft for further study by scientists. In the field of aerospace medicine, we have conducted lower limb kinematics testing experiments to study the biomechanical characteristics of astronauts’ movements in a weightless environment; we have conducted visual function research to explore the pathogenesis of spaceflight-related visual function damage to propose corresponding protection plans. . In addition, the Shenzhou 17 astronaut crew continued to cultivate the “space vegetable garden” and not only achieved bumper harvests one after another, but also staged “eating and broadcasting” in space, allowing netizens to taste the fruits of the two crews’ joint cultivation.

From Shenzhou 5 to Shenzhou 18, from a single person entering space to a three-person crew entering the Chinese Space Station, the number and types of various scientific and technological experimental projects have increased qualitatively. These experiments are not only of great significance to technological innovation on the ground, but also have a profound impact on human exploration of space and the establishment of space homes. For example, in the field of new space technology, the results of the space-efficient free-piston Stirling thermoelectric conversion test can reduce our reliance on traditional solar energy and provide more solid technical support for our future manned lunar exploration and deep space exploration missions.

The greater the undertaking, the more challenging it is. Heading towards the stars and the sea, the Chinese people are constantly exploring the romantic universe, and the scientific exploration of the dream of space is also constantly moving forward. As one major space mission project after another is carried out in an orderly manner, facing the future, we must continue to accelerate in innovation, continue to climb the peak of science and technology, and make more contributions to propel China from a space power to a space power!
