Shenzhou XV crew returns safely to Earth

The Shenzhou XV astronauts conducted four spacewalks and installed equipment outside the Tiangong station, becoming the most experienced Chinese team in terms of extravehicular space activities.

The crew lived and worked in the Tiangong complex for 186 days and conducted a number of fruitful experiments.

The astronauts successfully obtained three-dimensional structural images of their skin cells with China's self-developed two-photon microscope. This achievement, the first of its kind, marked the success of the in-orbit verification experiments of the two-photon microscope, providing a promising tool for future health monitoring of astronauts in orbit.
