神舟二十号
A specialized repair device was expedited to the launch center and installed inside the Shenzhou-20 capsule to reinforce thermal protection and sealing for reentry.
During the nine days after the Shenzhou-20 return postponement, six taikonauts were simultaneously on Tiangong and Wang Jie was responsible for ensuring stable operation of the environmental control and life support system.
During final pre-return inspection the Shenzhou-20 crew discovered a triangular crack that penetrated the outermost layer of the return capsule window.
The Shenzhou-20 crew used an integrated thermal roasting device with an internal range-hood function to heat and roast food on orbit, including steaks and chicken wings.
Chen Dong flew on the Shenzhou-11, Shenzhou-14, and Shenzhou-20 missions.
China conducted an emergency-response launch with the Shenzhou-22 spacecraft after the Shenzhou-20 return was postponed.
The Shenzhou-20 crew completed a crew handover with the incoming crew while both crews were on orbit.
Approximately 20 days elapsed between discovery of the Shenzhou-20 window problem and the safe return plus the successful launch and docking of Shenzhou-22.
Ground mission control assessed that Shenzhou-20’s return posed safety hazards and postponed the return while activating an emergency plan.
In microgravity during the Shenzhou-20 mouse experiment, the mice initially showed stress reactions to weightlessness and later adapted to move and feed normally.
The Shenzhou-20 crew performed multiple scientific experiments on orbit, including a mouse experiment and high-temperature materials tests.
The three Shenzhou-20 taikonauts have had their mental and physical health monitored since returning to Earth.
Wang Jie served as the science operator on Shenzhou-20 and operated and maintained the space station systems during the mission.
All six taikonauts from both crews participated in observing and verifying the Shenzhou-20 return capsule window condition with ground control.
The crack is located on the edge of the outermost glass pane of the Shenzhou-20 window.
The crack on the Shenzhou-20 window is triangular in shape and approximately 2 cm long.
Shenzhou 20 is an uncrewed return capsule.
Shenzhou 20 spent 270 days in orbit, setting a new Chinese record.
Shenzhou-20’s reentry module returned completed science experiments, personal items for the crews, and a Feitian (飞天航天服) spacesuit.
Recovery teams cut Shenzhou-20’s parachutes after touchdown because no taikonauts were onboard to send the parachute-cutting command.
