The 25 year threshold is a bright line in a continuum of possibilities that strikes a reasonable balance between ensuring everything comes home in a human-measurable amount of time but that does not levy arduous requirements on satellite manufacturers. Most satellites can do 25 years passively. Significantly less and they require de-orbit propulsion systems. | |
