The Shenzhou-23 crew aboard China's space station completed the assembly, testing and extravehicular installation of the Multi-Spectral Imaging Carbon Observatory (MUSICO), the first spaceborne greenhouse gas detector of the space station, in the past week.

This compact, high-resolution and high-precision detector can monitor concentrations of carbon dioxide and methane in key regions across the mid-and-low latitude regions on the Earth.

It is expected to provide data for tracking global greenhouse gas emissions and for conducting ecological environment research.

In addition to equipment installation, The three astronauts, Zhu Yangzhu, Zhang Zhiyuan and Lai Ka-ying, carried out experiments on microgravity physics, and explored how the light environment affects human psychological perception and work efficiency in the space environment.

They also performed maintenance work for the space station and used equipment to measure their noise exposure.

To monitor their physiological changes in the microgravity environment, the astronauts collected, centrifuged and stored blood samples, underwent cardiovascular function tests, intraocular pressure and fundus examinations, as well as ultrasound scans of multiple body parts, completed bone density measurements, and used a special weighing scale to measure their body mass in orbit.
