The Shenzhou-15 mission is ready for launch with various systems and preparations checked, after a joint pre-launch rehearsal(排练), said the China Manned Space Agency (CMS) on Sunday. Around 7:00 a.m. on Sunday, the Jiuquan Satellite Launch Center, the Xi’an Satellite Control Center and other space tracking and control facilities involved in this mission conducted a simulated launching procedure under the unified command of the Beijing Aerospace Control Center (BACC).

The Shenzhou-15 will be launched on Tuesday, November 29, 2022 from the Jiuquan Satellite Launch Center in northwestern China. It’s due to launch three Chinese astronauts to the China Space Station for a half-year trip. They will stay in the space station with the three-person Shenzhou-14 crew for a short time, who are preparing to head back to Earth. China’s manned space program will run two Shenzhou spacecrafts at the same time for the first time, creating new challenges.

The Yuanwang-6 spacecraft tracking ship, which will carry out the tracking and control mission, is now in its designated mission area. The Shenzhou-15 mission faces a difficult launch window in severe winter conditions, so teams including meteorological(气象的) support, measurement and launching have strengthened meteorological consultation and review of the related facilities. 

Wang Xuewu, deputy director of the Jiuquan Satellite Launch Center, said that “Judging from today’s joint rehearsal with inspection of all equipment and the entire system, we can say that all the systems of the rocket, the spaceship and the launch site are in good conditions.”

Chang Wuquan, chief designer of Long March 2F, also said that his team had connected the devices on the rocket and the ground equipment, and checked the condition of the whole rocket and its sub-systems according to the work plan. “Through inspections, we’ve confirmed that the rocket is ready for launch. We hope it can carry the Shenzhou-15 crew into the space smoothly,” said Chang.
