Scientific paper
A detailed account is given of engineering work done both on the ground and remotely to adapt the Voyager 2 spacecraft and assure that the best possible pictures would be received starting January 24, 1986, at the time of the encounter with Uranus and its moons. Voyager 2 was never intended to provide time-exposure pictures at Uranus and send back a data stream for conversion into images. Achieving this involved making changes in the way data was encoded and checked on the spacecraft as well as changes in the attitude-control logic to minimize spacecraft 'nodding' during thruster firing. Enhancements of the ground receiving and tracking system (e.g., larger antennas and linking of antennas) are covered. Photomaps of Umbriel, Ariel, and Miranda are included.
