ESA was "asking for it" when they designed a 65 ft antenna
ESA was "asking for it" when they designed a 65 ft antenna. There are so many opportunities for a thermo-elastic instability to occur. That sort of instability can cause the antenna to wag like a dog's tail (a structural engineer's nightmare). Once the instability forms, it becomes impossible to keep the high gain antenna pointed at the Earth.
