I’m confused. I thought Mars lacked a magnetic field. As such, what’s causing an aurora?

Good point. Perhaps this bit of settled science is becoming unsettled.

Mars has a very weak magnetic field, compared to Earth, but it does have stronger spots of permanently magnetized crust that would create localized magnetic fields, which probably also generate localized atmospheric electrical phenomena (lightning storms, etc).
