Abstract

Mars-Express is the European Space Agency's first mission to orbit another planet. The mission has a single-pointing system—that is, during regular operations, the space probe points either at Mars to perform payload operations or at Earth to download produced data. The Mars-Express Scheduling Architecture (Mexar2) is an AI-based tool to assist European Space Operations Center mission planners. Since its integration with the Mars-Express mission, Mexar2 has reduced the planning team's workload for generating a feasible downlink plan by half compared to the previous method.
