For the first time internationally, a Chinese team has achieved new results that may extend the lifespan of artificial satellites to 30 years

Recently, a team led by Zhou Peng and Ma Shunli from Fudan University successfully developed the "Qingniao" atomic layer semiconductor radiation-resistant RF communication system (hereinafter referred to as the "Qingniao" system). Based on the "Fudan No. 1" satellite platform, it has entered space and achieved the world's first on-orbit verification of "ultra-long lifespan" and "ultra-low power consumption" for two-dimensional electronic devices and systems. The "Qingniao" system not only extends the theoretical on-orbit lifespan of satellite communication systems to 271 years but also reduces energy consumption to one-fifth of traditional solutions, with a weight reduction to about one-tenth of the original. It is expected to increase the service life of artificial satellites from around 3 years to 20-30 years. On January 29th, Beijing time, this achievement was published online in Nature.
