The Pioneer Jupiter missions were done by direct command from earth, the only autonomous capability on the spacecraft was to do a turn by precessing the spin with attitude thrusters, a midcourse maneuver, and a turn back to earth pointing.
The high radiation environment close in to Jupiter caused a number of command errors, such as gain changes in the closest in images, etc. The Io image was mis-pointed and the target was missed. It would have been a fairly decent image, too, not that many kilometers/pixel, maybe 20 or so. |
