JIUQUAN, April 23 (Xinhua) -- Chinese astronauts Chen Dong, Chen Zhongrui and Wang Jie will carry out the Shenzhou-20 crewed spaceflight mission, and Chen Dong will be the commander, the China Manned Space Agency announced at a press conference on Wednesday.

The Shenzhou-20 crewed spaceship is scheduled to be launched at 5:17 p.m. Thursday (Beijing Time) from the Jiuquan Satellite Launch Center in northwest China, said Lin Xiqiang, spokesperson of the agency.

Chen Dong participated in the Shenzhou-11 and Shenzhou-14 space missions. He served as the commander of the Shenzhou-14 crew and will take on the mantle once again after a two-year interval. He will also become the first among China's second batch of astronauts to carry out three spaceflight missions.

Chen Zhongrui and Wang Jie both come from the third batch of astronauts and will embark on their first spaceflight mission. Before being selected, Chen Zhongrui was an air force pilot, while Wang Jie was an engineer at the China Academy of Space Technology under the China Aerospace Science and Technology Corporation.

Chen Dong described his crew as embodying a synergy of precision and rigor. Speaking to the press on Wednesday, he said the pilot brings sharp thinking and precise operational skills, while the engineer contributes a meticulous attitude and a solid theoretical foundation.

"I have full confidence in our team, and it is capable and resourceful. We collaborate effectively, with each member fulfilling their role and handling responsibilities independently," he added.

The Shenzhou-20 astronauts will complete in-orbit rotation with the Shenzhou-19 crew and stay at the space station for approximately six months, according to Lin.

The new crew will undertake a range of tasks, including space science experiments, application tests, extravehicular activities, and cargo handling. Their mission also involves installing protective devices against space debris, deploying and retrieving extravehicular payloads and equipment. They will also participate in science education, public outreach, and other onboard experimental activities.

The Shenzhou-19 astronauts are scheduled to return to the Dongfeng landing site in north China's Inner Mongolia Autonomous Region on April 29, Lin said.
