=== Subject: [amsat-bb] Yoshihide Kozai
The long scientific life of Kozai ended recently with his death at ~90 years old
Kozai and Lidov proposed a mechanism for why the Luna 3 probe decayed into the Earth's atmosphere when everyone believed it would last "forever".
This same mechanism describes the death of which amateur spacecraft?
