China manned space program's chief taikonaut system designer, Huang Weifen, has commended the Shenzhou-15 crew's performance during their stay in the China Space Station, and emphasized the growing significance of space applications for taikonauts.

She said that the Shenzhou-15 crew has spent over 180 days in orbit and during their in-orbit flight, they have successfully conducted four extravehicular activities and handled various payload deployments.

"They also conducted extensive in-orbit scientific research experiments, installed a lot of experimental cabinets, and effectively managed station tasks, materials, equipment maintenance, and operations," Huang said.

"They have fulfilled all assigned tasks. And they worked very well together," she noted.

The chief designer went on to stress the significance of the space application in China Space Station.

"The construction of the space station is primarily aimed at facilitating applications, with relevant scientific research experiments being a crucial task for the taikonauts," she said.

During the station's construction phase, the four flight crews from Shenzhou-12 to 15 accomplished the assembly, testing, debugging, and activation of 28 experimental cabinets across the three modules, including the installation of the extra-cabin payload platform.

"They conducted over 600 rounds of experiments encompassing 200 projects. They collected approximately 500 samples back to Earth," Huang said. "These offer invaluable research data in fields such as aerospace medicine, psychology, engineering technology, and materials sciences."

Looking ahead, she said that during the space station's application and development stage, taikonauts or astronauts are expected to play a very important role in conducting numerous scientific research endeavors.
