Atmospheric attenuation allows unpowered orbital mechanics to remain stable over time.
Atmospheric attenuation (drag) causes low Earth orbit satellites to continuously lose energy and decay rather than remaining stable over time.
The claim states that atmospheric attenuation allows orbital mechanics to remain stable. In orbital mechanics, atmospheric drag (attenuation) actually causes orbital decay, removing energy from the orbit and leading to altitude loss unless counteracted by active propulsion (thrusters). Papers [0], [3], [6], and [8] all confirm that atmospheric drag acts as a disruptive perturbation leading to orbital decay.

This study demonstrates that atmospheric drag causes orbital decay and requires active thrusters to maintain stable low Earth orbits.
