Figure 7.7: A geometric model (left) of the Pioneer spacecraft, used for finite element analysis, and a photograph (right) of Pioneer 10 prior to launch. The geometric model accurately incorporates details such as the Medium Gain Antenna (MGA), the Asteroid-Meteoroid Detector, and the star sensor shade. Note that in the geometric model, the RTGs are shown in the extended position; in the photograph, the RTGs are stowed. From [171, 172]. |
