The engineers of the Voyager 2 mission to Uranus had to deal with dwindling consumables, navigational challenges unique to the Uranian system, low light-level imaging, increasing communications problems, and failed equipment onboard the spacecraft, each of which could affect the success of the mission. The techniques for coping with each of these factors are discussed in detail. For instance, steadying of the spacecraft, achieved by cancelling the momentum change imparted to it by high-rate operations of the digital tape recorder, enhanced the data quality from several instruments, particularly the cameras. A careful power management scheme made it possible to conduct a successful radio occultation experiment which yielded detailed information on the Uranian atmospheric structure, including temperature and composition. A unique picture of the back-lit ring system was obtained.
