>At end of life, the satellites will utilize their on-board propulsion system to deorbit over the course of a few months. In the unlikely event the propulsion system becomes inoperable, the satellites will burn up in Earth’s atmosphere within 1-5 years So, how long a lifespan do these satellites have if their propulsion system works properly to keep them in orbit?
