Shenzhou-23 astronauts Zhu Yangzhu, Zhang Zhiyuan and Li Jiaying, now more than
four months in orbit, completed external payload ingress/egress last week while
advancing in-station science and routine platform maintenance. The outside
universal testbed they handled includes units for an air‑core photonic‑bandgap
fiber gyroscope, advanced process devices and a remote‑sensing target‑detection
experiment based on domestically produced AI chips. With ground support they
recovered a materials exposure experiment unit launched on Tianzhou‑5 on Nov.
12, 2022; that platform ran three batches covering 16 exposure projects and
several international firsts and is now on a fourth campaign covering eight
research projects with 26 sample units. Onboard work included tactile‑perception
tests (quality perception and arm vibration) to study changes in touch
sensitivity in microgravity, emergency‑decision capability assessments and
on‑orbit mood‑state testing. For station upkeep the crew replaced components in
the regenerative life‑support system’s water–gas separator and completed medical
checks (12‑lead ECG, non‑invasive cardiac function) and countermeasures against
bone loss and neuromuscular decline using anti‑bone‑loss and neuromuscular
stimulation devices.
