Initially, the device, which was initially designed for the first eight orbit, began to suffer from radiation damage after the 47th openness of the planet. In the 56th round, almost all images taken were spoiled.
To save the camera, the team applied the annealing method: The JunoCam case was heated to 25 ° C and then slowly cooled.
This procedure partially eliminated microscopic defects caused by radiation. Soon the camera started to convey clear images again.
However, after a few orbit, the problems returned. Then the engineers decided on a more intense pan. Just a few days before getting closer to IO, the quality of the pictures developed sharply and allowed to obtain detailed images of the satellite surface.
Since then, a similar method has already been used to other systems of the device. According to scientists, the information gained will help create more radiation -resistant spacecraft and satellites to be used by the Earth.
