Over the past six months, Chinese astronauts have achieved fruitful scientific experiments by conducting multiple scientific experiments and experiments in orbit, China MannedSpaceAgencysaid recently.
In March, with the cooperation of scientific researchers on the ground and astronauts, the crew of Shenzhou 15 completed the first ignition test of the combustion science cabinet experiment system. Methane was used as the fuel for the ignition experiment, and the high-speed camera clearly photographed the entire ignition and combustion process, laying a good foundation for the smooth implementation of subsequent projects.
The astronauts conducted experiments on the space station"s two-photon microscope project in orbit, generating the first three-dimensional images of astronaut skin epidermis and superficial dermis obtained during space flight.
The astronauts completed in orbit the test of the space efficient free piston stirling thermoelectric conversion test device, making the comprehensive technical indicators of thermoelectric conversion efficiency reach the international advanced level.
In May, three astronauts from Shenzhou XV conducted in orbit observation experiments for over 5 months, achieving the first observation of the process of conductive ring debris generation and cluster phenomena in orbit.
In the meantime, the astronauts completed China"s first liquid metal thermal management in orbit test and achieved a series of key technological achievements.
From June 9 to 10, the crew of Shenzhou 16, who had just arrived at the space station, also completed the exit of the space radiation biological exposure experimental device of the Mengtian module, making it the first ever extravehicular radiation biological exposure experiment that China has ever carried out.
