Shenzhou-19 Crew Marks 100 Days in Orbit | China Space Station
China's Shenzhou-19 crew has spent 100 days aboard the Tiangong Space Station since the launch over three months ago, successfully carrying out mission assignments and celebrating the traditional Chinese Spring Festival in orbit.
The Shenzhou-19 crew was launched into space on October 30, 2024, for a six-month mission, prior to the end of the previous Shenzhou 18 mission. Saturday, February 8, 2025, marked the 100th day in space for the three astronauts—Cai Xuzhe, Song Lingdong, and Wang Haoze.
During the 100 days, the Shenzhou-19 crew members carried out their duties efficiently aboard the Tiangong Space Station, maintaining a steady workflow and ensuring mission objectives were met as planned.
Last week and earlier, the three astronauts celebrated the Spring Festival, or the Chinese New Year holiday, in orbit, marking the fourth Spring Festival celebrated by Chinese space station crew.
The astronauts pasted Spring Festival couplets, hung the Chinese characters of Fu (good fortune) and shared a New Year's Eve family reunion dinner on January 28 to celebrate the festival in space.
The crew donned festive outfits and extended their new year wishes to Chinese people, and called their families and friends via video link on this festive occasion.
Over the past 100 days, they conducted daily duties, such as station management and various space science experiments efficiently.
The astronauts also completed blood sample collection, centrifugation, packaging and freezing.
The samples will be analyzed by ground researchers to study the changes in bone-related physiological systems during long-term spaceflight and the effects of the space environment on gene expression regulation.
The crew also used the relevant equipment and software to conduct behavioral tests and fine motor control tests with the testing data intended to explore the impact of gravity on visual motion information processing and the cognitive mechanisms behind fine motor control in microgravity.
Moreover, the crew completed in-orbit emotional state assessments and evaluations on emergency decision-making ability as part of ongoing research into astronaut psychology and behavior.
As per their schedule, the crew underwent medical checks using instruments, like traditional Chinese medicine diagnostic tools and bone density meters to monitor their health, while conducting physical exercise.
