The Mars Express spacecraft, despite a series of intense solar flares that occurred late October-early November in active sunspots regions, is in good health and is operating normally. The spacecraft flew in the intense radiation environment that resulted from the exceptional solar and geomagnetic activity associated with these regions, temporarily causing disturbances on the star trackers. These disturbances, which were over within a few days, did not cause damage and did not constitute a threat to the mission.
