The success of the Voyager 1 flyby of Titan permitted configuring the Voyager 2 trajectory for flybys of Uranus and Neptune. Satellite instruments will gather data on the Uranian atmosphere, rings, satellites and magnetosphere (if there is one). The observational sequences were coded for transmission to Voyager 2 in November 1985. Earlier commands have stabilized the spacecraft to avoid image smearing during the approach and have reduced the time of firing of the thrusters for course changes. Imaging data compression will economize on the degraded communications link to Voyager 2 and lower the demands on the slowly failing radiothermoelectric power supply. The encounter will take place in February 1986 and, should failure of the command link occur, be accompanied by carrying out of a preprogrammed set of observational and operational sequences lasting through a 1989 Neptune flyby.
