The damagemodelhas been made andtheanalysisof the relation damage andturn Angle has been studied to giveabetter understandingof the damage theory, damage course anddamage effect factors.
Rotational symmetry means that if you turn something through a fixed angle, it looks the same (as a starfish would if you turned it through a fifth of a circle).
That, in turn, depended on the angle and amount of sunlight falling on Voyager, and the amount of heat generated by its various components as they were switched on and off.
