The Global Precipitation Measurement Mission (or GPM) spacecraft (1, 2) has two solar array panels. They extend from opposite sides and one is tilted with respect to the other.
This is a slightly unusual arrangement. Why are they angled so differently, and are either, or both of these actively rotated with respect to the spacecraft to maximize power as the spacecraft rotates around the Earth? If so, do they rotate once completely for each orbit around the Earth?
