Seminar Abstract:

Lunar magnetic anomalies were discovered during the Apollo era, but their exact origin remains a puzzle.  The solution will have implications for understanding the origin and history of the lunar dynamo.  Interestingly, some magnetic anomalies are also associated with bright color markings on the surface known as swirls.  Swirls are likely areas where “space weathering” is disrupted, and therefore they are natural laboratories to study this process.  I will present new results that provide insight into the formation mechanism of swirls, and observations that show that at high latitudes the lunar maria mimic the color changes seen at swirls.  This latter observation can even be seen with the naked eye.  Finally, I will present a low-cost mission concept that would provide greater insight into the origins of swirls and magnetic anomalies.
