Tiangong: Expedition 10

Expedition 10 began with undocking of Shenzhou-21 on November 14, 2025.

Zhang Lu and Wu Fei performed perform the first spacewalk on December 09, 2025 (8h 17m). The Shenzhou-21 crew astronauts Zhang Lu, Wu Fei and Zhang Hongzhang worked closely together, and with the support of ground scientific researchers to the astronauts exited the Wentian module, while Zhang Hongzhang remained in Tiangong. They successfully completed tasks including inspecting and photographing the windows of the Shenzhou-20 spacecraft's return capsule, installing the space debris protection device on the space station, and replacing the multi-layer cover of the temperature control adapter.
They meticulously documented the damaged window on the return module of the Shenzhou-20 spacecraft. After evaluation, a decision will be made regarding its future. It seems highly likely that a protective element will be installed and the spacecraft will be returned unmanned.

At 11:35 UTC on March 16, 2026, after a 7-hour extravehicular activity, the Shenzhou-21 crew of astronauts Zhang Lu, Wu Fei and Zhang Hongzhang, working closely together with the support of the space station's robotic arm and ground researchers, successfully completed tasks including the installation of space debris protection devices. Astronauts Zhang Lu and Wu Fei have safely returned to the Wentian experimental module, marking a complete success for the extravehicular activity. Astronaut Zhang Lu has now conducted a total of 6 extravehicular activities, making him one of the Chinese astronauts with the most extravehicular missions to date.
