@jknodlseder @sundogplanets Orbital lifetime up that high depends a lot on eccentricity (higher e meaning more drag at perigee) and inclination, right?
e.g. I recall discussions about deliberately disposing of MEO satellites by inducing eccentricity oscillations.
But that supposes that the operator of the satellite acts responsibly. Which neither Starlink nor the various other aspiring LEO megaconstellations are.
