The status of Giotto is reviewed, and an extended mission is shown to be feasible. One week after the Halley flyby, Giotto's orbit was changed so that it can return to the Earth. Using an Earth swingby on 2 July 1990, Giotto could be targeted to encounter a second comet. The short-period comet Grigg-Skjellerup was selected as the most suitable target. The encounter would occur on 10 July 1992, 12 days before its perihelion passage. Before the decision can be made to extend the Giotto mission the spacecraft and all experiments will be carefully checked out. This campaign is scheduled to take place at the end of 1989/early 1990, when Giotto, for the first time after the Halley encounter, is within 1 AU geocentric distance.
