The Divine Fifteen Team has completed multiple "firsts" and is about to return! "Space Business Trip" for Half a Year Shenzhou | Experiment | Crew
"On a business trip" for six months, the Divine Fifteen Riders completed all established tasks
After six months of space travel, the three astronauts of Shenzhou-15 are finally returning to their homes on Earth. As the "Dream Team", their in orbit work is also very busy. What tasks have they completed in the past six months? Let's learn about it through a set of data.
It is reported that during orbit, the crew of Shenzhou-15 completed 4 extravehicular activities, 8 human factors engineering technology research, 28 aerospace medical experiments, 38 space science experiments and experiments, as well as long-term residency verification of the status of the three modules of the space station. They successfully completed all established tasks and obtained valuable experimental data.
Outbound activities are a very important task for astronauts during their time in orbit. The three astronauts of Shen-15 worked closely together to complete four extravehicular activities in two months from February 10th to April 15th this year. This not only completed the first extravehicular activity of Chinese astronauts after the full completion of the Chinese space station, but also broke the record for individual crew extravehicular activities of Chinese astronauts.
Multiple "first" scientific experiments conducted by the Shenshiwucheng group have yielded fruitful results
Just now we also mentioned that the Shenzhou-15 crew conducted many scientific experiments during its orbit, among which several projects were first-time. Let's learn more together.
During the in orbit period, the crew of Shenzhou-15 spacecraft used a space station two-photon microscope independently developed by China to carry out in orbit verification experiments and achieved success. This is currently the world's first known three-dimensional image of astronaut skin epidermis and superficial dermis obtained using a two-photon microscope during space flight, providing a new tool for future research on astronaut in orbit health monitoring.
During the in orbit period, the crew of Shenzhou-15 astronauts also completed in orbit testing of the space efficient free piston Stirling thermoelectric conversion test device, which is also the first time China has achieved in orbit verification of this technology. Stirling thermoelectric conversion is one of the key technologies for space new energy. It can efficiently convert thermal energy into electrical energy, and has advantages such as simple structure, light weight, and fast startup. It can reduce dependence on traditional solar energy and has broad application prospects in future manned lunar and deep space exploration missions.
In March of this year, with the collaboration of ground researchers and astronauts, the experimental system in the combustion science cabinet of the Dream Module successfully conducted its first in orbit ignition test. The ignition experiment used methane as fuel, and the high-speed camera captured the entire ignition and combustion process clearly. This experiment verified the completeness of the functionality of the space station combustion science experimental system, as well as the accuracy and scientificity of the overall experimental process.
In May of this year, three astronauts also achieved in orbit observation for the first time of the generation process of conductive ring debris and cluster phenomena, which laid a good foundation for improving the design of space conductive ring products for various spacecraft and ensuring reliable and stable operation of spacecraft in orbit.
