The Magellan mission is intended to investigate the origin and evolution of Venus. The launch date for this mission was originally set for April 1988, and it was scheduled to end in April 1989. Since then the launch date has changed twice. At the start of the project in fiscal year 1984, NASA estimated the project's total cost at $294.6 million, assuming that the spacecraft would be launched by the shuttle in April 1988 and would use a Centaur upper stage to provide propulsion into an interplanetary trajectory. In October 1987, the mission cost estimate was increased about $219 million to $513.5 million, which was a result of launch delays adopting to a new upper stage, accommodating a new trajectory, and problems with the development of the mission's major scientific instrument. The Magellan mission is described, its cost is estimated, its schedule chronicled, and its performance predicted. The mission's objective to map at least 70 percent of the Venus surface is expected to be achieved.
