NASA’s Cyclone Global Navigation Satellite System (CYGNSS), which launched in 2016, is deorbiting on New Year’s Day. The technology will live on, commercialized by Muon Space, a Silicon Valley startup that grew out of a Stanford class project.   The satellites lack propulsion systems, so they have been steadily losing altitude since launch.  They would naturally deorbit sometime next year, burning up on reentry, but NASA decided… The post No propulsion, no problem: How CYGNSS’s solar panels will enable deorbit without propulsion appeared first on Research & Development World .
