Tangentially related (taking pictures of things on spacecraft with impaired systems for tracking the objective)... https://llis.nasa.gov/lesson/394 https://llis.nasa.gov/lesson/394 > The Voyager 2 scan platform, on which are mounted the spacecraft cameras and several science instruments, is rotated in elevation and azimuth by actuators. Near the end of the Voyager 2 Saturn encounter, the scan platform azimuth actuator exhibited an anomaly. This anomaly was evidenced by the azimuth actuator seizing, causing a scan platform pointing error that resulted in a loss of some data. Through a series of ground commands, the problem was alleviated to the extent that the scan platform could perform its function. ... https://www.nytimes.com/1981/08/27/us/camera-swivel-on-voyager-sticks-while-craft-passes-behind-saturn.html https://www.nytimes.com/1981/08/27/us/camera-swivel-on-voyag... https://www.nytimes.com/1981/08/28/us/swivel-on-voyager-still-misbehaving.html https://www.nytimes.com/1981/08/28/us/swivel-on-voyager-stil... Voyager engineering improvements for Uranus encounter - https://ntrs.nasa.gov/citations/19860063178 https://ntrs.nasa.gov/citations/19860063178 > Finally, engineering improvements made in order to enhance scientific findings at the Uranus encounter are reviewed in detail. The two most important were the increased gyro drift turn rate capability to accommodate image motion compensation for the close fly-by of Miranda and the reduction in spacecraft rates to accommodate increased imaging exposure times without incurring excessive image smear.
