Chinese Team Demonstrates 2D Semiconductor Radio in Space, Claims Leap in Satellite Lifetimes

Fudan University researchers have flown a 2D semiconductor RF communications system on the Fudan-1 satellite and published results in Nature claiming dramatic reductions in power and mass and a theoretical device lifetime of 271 years. While the demonstration is an important milestone for radiation-hardened electronics, practical satellite lifetimes remain constrained by other subsystems and will require broader validation before reshaping industry norms.
