Abstract: Aurora on Mars Aurorae have been observed on most planets in the Solar System. Mars seemed to be one of the exceptions — until Mars Express got there. Its SPICAM ultraviolet spectrometer has detected a martian aurora, different in important ways from any reported for other planets. The martian aurora is localized to one spot, clearly associated with the crustal magnetic field discovered and mapped by the Mars Global Surveyor. This field is a remnant of an ancient intrinsic magnetic field now extinct.
