On November 4th, at 1:24 am Beijing Time, the Shenzhou 18 spacecraft safely landed at the Dongfeng landing site. It carried three astronauts: Ye Guangfu, Li Cong, and Li Guangsu. Medical teams checked them and said that they are all in good health. The Shenzhou 18 mission was a success!

The three astronauts spent a record 192 days in space. They carried out lots of scientific experiments. Now, they have returned with about 34.6 kg of test samples (样品). These samples have been handed over to scientists to study.

The astronauts’ safe return is a big win for China’s space program and adds to its space “story”. Since the start of the space age, China has made huge strides in space, including launching its first manned spacecraft and building the China’s Space Station. The successful return of the astronauts shows how hardworking the space team is. As technology improves, China is expected to do even more in space exploration.
