The disturbance created by Siwarha produces a dense wake of material.

Research at the Center for Astrophysics | Harvard and Smithsonian links the wake produced by Siwarha to changes in Betelgeuse.

Astronomers using NASA's Hubble Space Telescope and ground-based observatories have traced how Siwarha, Betelgeuse's companion star, disturbs gas in Betelgeuse's extended atmosphere.

Zhang Lu, Wu Fei, and Zhang Hongzhang were onboard the Tiangong Space Station for the Shenzhou-21 mission just before the New Year.

Taikonaut instructor Jiang Yuan noted that data on psychological states in extreme environments will aid in establishing a psychological support system for future missions.

Taikonaut Zhu Yangzhu highlighted that cave training enhances teamwork skills valuable for future spaceflight missions.

Commander Zhang Lu sent a New Year's message from inside the Wentian experiment module of the Tiangong Space Station.

The cave training environment simulated conditions of isolation, claustrophobia, and high-risk scenarios that the taikonauts will experience in space.

The taikonauts were divided into four groups and spent six days and five nights underground for training.

Wu Fei is the Flight Engineer for the Shenzhou-21 mission and it is his first trip into space.

The China Astronautic Scientific Research and Training Center conducted surveys to find suitable caves for taikonaut training.

In June 2016, Ye Guangfu participated in a caving course in Italy, where he trained with colleagues from the United States, Spain, Japan, and Russia.

At the end of the cave training, the groups conducted a brief jungle survival exercise, including tasks to signal for rescue.

As of mid-2024, a total of forty-four individuals are prepared for space missions within China's taikonaut corps.

Wu Bin from the China Astronautic Scientific Research and Training Center outlined the rationale for the cave training as improving capabilities for manned space missions.

China is developing hardware such as the Lanyue lunar lander, Mengzhou crew capsule, Wangyu lunar spacesuit, and Tansuo rover.

Taikonauts wore insulating clothing and had to carry their own equipment and supplies while navigating the cave.

During the cave training, the taikonauts had to map their route, gather data on the environment, and collect samples.

The group commanders for the training were Wang Yaping, Liu Yang, Cai Xuzhe, and Tang Hongbo, with equal representation of men and women.

In December 2025, twenty-eight taikonauts participated in cave training exercises in Wulong, Chongqing, ahead of lunar exploration missions.

Veteran taikonauts Ye Guangfu and Zhai Zhigang monitored the safety and condition of their colleagues during the training.

Regular inspections and maintenance of the space treadmill and life support equipment were completed by the crew.

In January 2026, the crew of Shenzhou-21 engaged in various missions, including space medicine experiments and routine emergency drills.

Zhang Lu is the Commander and Pilot of the Shenzhou-21 mission and is a veteran of the Shenzhou-15 mission.

In case of emergencies, communication lines and a video surveillance system were installed in the cave for monitoring progress.

Zhang Hongzhang is the Payload Expert for the Shenzhou-21 mission, marking his first spaceflight.

Taikonauts involved in the Shenzhou-21 mission collected kinematic data on their movements using specialized equipment during their in-orbit activities.

As a result of the cave training, many of China’s spacefarers are now partially trained for crewed lunar missions.
