China announced on November 22 that it had successfully conducted an in-orbit expansion test of a small expandable module.

Expandable modules can be used for various missions, such as building space stations or lunar bases. Since the modules are transported in a compact, folded state on rockets, they significantly improve transport efficiency.

The expandable module used in this test was attached to the Shijian-19 satellite, launched by China on September 27, and underwent expansion testing in a predetermined orbit.

Shijian-19 is a partially reusable satellite, with some components returning to Earth on October 10.

The module was developed by the China Academy of Space Technology (CAST), which described it as a “multifunctional airtight structure made of flexible composite materials.” CAST further stated, “The technology validated in this test will be applied to the development of large-scale airtight modules.”

Before being sent into space, the module underwent ground testing for airtightness, debris impact, extreme pressure, vibration, and thermal vacuum conditions.
