The Shenzhou-21 space crew successfully completed their primary objective during their spacewalk, which was inspecting and photographing the viewport window of the Shenzhou-20 return capsule, according to the China Mainland Space Agency.
Two cracks were found in the window, likely caused by external impacts from space debris.
As a result, the Shenzhou-20 did not meet the safety requirements for the astronauts' return and has remained in orbit.
The spacewalk crew completed their assigned tasks after more than eight hours, with assistance from the space station's robotic arm and ground-based research fellows.
According to space experts, this is the first time that two manned spacecrafts have docked in the space station complex during a spacewalk, posing challenges for path planning and astronauts' support at the work sites.
