On December 17, 2024, two Chinese astronauts, Cai Xuzhe and Song Lingdong, made history. They did a spacewalk outside the Tiangong Space Station and broke a world record. They are part of the three-person team on the Shenzhou 19.

The spacewalk started in the afternoon. Cai went out of the space station first at 12:51 p.m. Song followed him about 90 minutes later. After working very hard for 9 hours and 6 minutes, they came back to the station at 9:57 p.m. Before this, the longest spacewalk was 8 hours and 56 minutes. American astronauts James Voss and Susan Helms set that record in March 2001. Our Chinese astronauts walked 10 minutes longer!

While Cai and Song were outside, Wang Haoze stayed inside the space station. She made sure everything worked well. The three astronauts worked together. They also got help from the space station’s robot arm and the scientists on the earth. Cai and Song did many important things during the spacewalk. They checked tools and put in a machine to protect the space station from space junk. Their work was a big success!

This spacewalk is the 17th time Chinese astronauts have worked outside the Tiangong Space Station. These brave astronauts’ hard work is good for China and the whole world. They are heroes. Their work shows us that everything is possible if we try hard. Their success tells us to dream big!
