Two new extravehicular spacesuits are able to provide astronauts with greater comfort and convenience during spacewalk activities, according to the China Manned Space Agency (CMSA) on Thursday.

These two new suits, delivered to orbit in July 2025 by the Tianzhou-9 cargo spacecraft, feature improvements in thermal comfort, human-machine interface capability and operational safety, while maintaining high standards of reliability, Zhang Jingbo, spokesperson for the CMSA, said on Thursday at a press conference focused on the upcoming Shenzhou-21 crewed spaceflight mission.

Notably, one in-orbit spacesuit, which was used more than 20 times, exceeding its original design of 15 uses within three years, will retire from future extravehicular missions.

Zhang said it is the first Chinese spacesuit to undergo in-orbit lifespan assessment and extended use -- validating the accuracy of health monitoring and evaluation models and methods for extravehicular spacesuits.

He added that further tests will be carried out on the suit's key materials and characteristic parameters. It is scheduled to be returned to Earth via a new-generation spacecraft at a later stage.
