Shenzhou No. 18 essay

Shenzhou 18 and Shenzhou 19 were two launch missions in China's manned space program. According to the information provided, the flight crews of Shenzhou 18 and Shenzhou 19 had been confirmed and were undergoing training. The two manned missions would carry out a series of missions, including space station maintenance, scientific experiments, and assembly missions. The launch mission labels of Shenzhou 18 and Shenzhou 19 were a yellow line that highlighted the Chinese space station and a red, yellow, and blue circular logo. The numbers "18" and "19" represented the mission number and corresponded to the number of stars. The launch time and specific details of these missions have not been provided.

Shenzhou 18 was the 18th spacecraft launched by China's manned space program. It was launched at the Jiuquan Satellite Launch Center at 20:58:57 on April 25,2024 and successfully entered the scheduled orbit. The Shenzhou 18 manned spacecraft was made up of three astronauts, Ye Guangfu, Li Cong, and Li Guangsu. They would stay in the space station for about six months to carry out space station management, maintenance, and repair tasks. The launch of Shenzhou 18 was a complete success, and the astronauts were in good condition. During their work on the space station, the Shenzhou 18 astronauts would also carry out several extraterrestrial activities. The return of Shenzhou 18 was scheduled for late October.

In 2024, the Shenzhou 17 manned spacecraft carried out two extraterrestrial activities. The second extraterrestrial activity was the first time a Chinese astronaut completed the maintenance mission of a spacecraft extraterrestrial facility in orbit. The focus of this extraterrestrial activity was to complete the maintenance work of the solar wings in the Tianhe core module, eliminating the impact of the impact of small space particles in the early stage. After evaluation and analysis, the power generation performance of the solar wings was normal. After the mission of the extraterrestrial activity was completed, the Shenzhou 17 manned spacecraft and the space station combination were successfully separated, and the astronauts safely returned to the Wentian experiment module. The mission of the Shenzhou 17 manned spacecraft was a complete success.

On April 26,2024, the Shenzhou 18 manned spacecraft successfully docked at the space station's Tianhe Core module. The entire autonomous rendezvous and docking process lasted about 6.5 hours. The docking was done using the autonomous rapid rendezvous and docking mode, and the space station assembly was docked in a radius. The rendezvous and docking was a difficult task because the space station assembly blocked the spacecraft's measurement sensors and the interaction between the engines would pose a challenge. In order to eliminate these risks, the development team controlled the deviation of the performance parameters of the docking mechanism through the development of product and process standards, and conducted several ground standard process capture buffer tests. The docking of Shenzhou 18 marked the further maturity of China's self-developed space rendezvous and docking technology.

In 2024, the Shenzhou 17 astronauts were composed of Tang Hongbo, Tang Shengjie, and Jiang Xinlin. They successfully completed the Shenzhou 17 manned flight mission, including extraterrestrial activities and extraterrestrial maintenance missions. On April 30, 2024, they returned to Earth safely and successfully landed at the Dongfeng Landing Field. The astronauts were in good health and the mission was a complete success. Tang Hongbo became China's longest-flying astronaut, with a total of 215 days in orbit. The return of the Shenzhou 17 astronauts marked the successful completion of their mission and their safe arrival in Beijing.

Shenzhou 15(SZ15) was the 15th Shenzhou spacecraft launched by China's manned space program and the 10th manned spacecraft launched by the People's Republic of China. Shenzhou 15 was launched on November 29,2022 by the Long March 2F launch vehicle at the Jiuquan Satellite Launch Center and docked with the Tianhe Core Vehicle. The three astronauts of the Shenzhou 15 crew would fly in orbit for six months. During this period, they would assemble, test, and commission the load equipment in the cabin, control the robotic arm to install the load outside the cabin, and rotate with the Shenzhou 14 crew in orbit. The purpose of Shenzhou 15's mission was to verify the space station's ability to support crew rotation, carry out the installation and adjustment of the space station's internal and external equipment and space application mission related facilities and equipment, carry out space science experiments and technical experiments, carry out daily maintenance of the space station, and verify the normal operation mode of the three-module combination of the space station.

Shenzhou 15 was a flight crew of China's manned space project consisting of astronauts Fei Junlong, Deng Qingming, and Zhang Lu.

Shenzhou 15 was the 15th Shenzhou spacecraft launched by China's manned space project and the 10th manned spacecraft launched by the People's Republic of China. Shenzhou 15 was launched on November 29,2022 by the Long March 2F launch vehicle at the Jiuquan Satellite Launch Center and docked with the Tianhe Core Vehicle. The three astronauts on Shenzhou 15 would fly in orbit for six months. During this period, they would assemble, test, and commission the onboard load equipment, operate the robotic arm to install the extraterrestrial load, and perform operational management and maintenance of the space station. The Shenzhou 15 crew would also rotate with the Shenzhou 14 crew to achieve continuous human presence. The Shenzhou 15 manned mission was a complete success. The astronauts returned to the Dongfeng landing site on June 4,2023 after working and living in orbit for six months.

Shenzhou-6 was the sixth spacecraft launched by China's manned space project and also China's second manned space mission. It was launched on October 12, 2005 and successfully landed on October 17, completing the mission of "multi-person multi-day" space flight. Shenzhou-6 was an important milestone in China's manned space project, marking the smooth start of the second step of the project. The spacecraft was developed by China Aerospace Science and Technology Corporation. Its main mission was to conduct scientific experiments, such as bone cells on the Earth's surface, cardiovascular medicine, digital photos, and test spacecraft. The Shenzhou-6 had the same shape as the Shenzhou-5 and weighed about 8 tons. It was launched using the Long March 2F launch vehicle. It was China's first manned spacecraft to carry out the mission of "many people and many days", making an important contribution to the development of China's space technology.

The return date of Shenzhou 17 was April 30, 2024.
