The Dongfeng landing site in Inner Mongolia of north China is ready for the return of the Shenzhou-18 astronauts, according to the Jiuquan Satellite Launch Center.
The last comprehensive drill was carried out at the landing site from Thursday evening to early morning on Friday, said the center.
The return capsule of the Shenzhou-18 manned spaceship, carrying three astronauts, is scheduled to touch down on Earth in the early morning on Monday.
The comprehensive drill simulated all possible scenarios and tested every piece of equipment, taking into account of various challenging conditions, the center said.
"We conducted multiple rounds of self-training and separate drills previously. Today, we held a full-scale air-ground joint search and rescue exercise, which proved that we've achieved the expected effect. As we'd carry out the search and rescue mission at night, and it is dark night now, so it's challenging to us to a certain extent. Our team has performed flights on night-vision devices before, which plus our aboard equipment and additionally installed electro-optical pod could assist us in quickly tracking the return trajectory of the spacecraft," said Wei Guo, an officer of the air search and rescue team of the Shenzhou-18 mission.
"Our joint exercise today went relatively smoothly, especially people of our various systems coordinated very well. Our air and ground teams, right upon their arrival, also delivered very normal teamwork. We have the ability and confidence to complete the search and rescue mission," said Sun Liwen, an officer at the Jiuquan Satellite Launch Center.
The three Shenzhou-18 astronauts, Ye Guangfu, Li Cong and Li Guangsu, were sent into space on April 25.
China launched the Shenzhou-19 crewed spaceship on Wednesday, sending another three astronauts to its orbiting space station for a six-month mission.
The Shenzhou-19 and Shenzhou-18 crews met in the Tiangong space station, and performed a new round of in-orbit crew handover.
