PhD Position: The Origin of Lunar Crustal Magnetization

100%, Zurich, permanent

We are looking for a highly motivated PhD student interested in studying the lunar magnetic fields and crustal structure. Your research will be part of an SNSF funded project “Using magnetic fields to explore terrestrial bodies in our Solar System” and offers a PhD position with PI Dr. Anna Mittelholz . The position is expected to start in spring/summer 2024. 

Project background

As an increasing number of missions are heading to the Moon, this PhD will focus on understanding the evolution of lunar crust, with a particular focus on its magnetic and gravity signatures. 

Magnetic dynamos are result of vigorously convecting iron in the core and thus, their presence or absence serves as window into the deep interior. The crust provides a record of ancient dynamo fields because when rock gets emplaced, e.g. in volcanic eruption, or heated/shocked, e.g., during an impact, it can get magnetized in the presence of a dynamo field. At the same time rocks get demagnetized if any of those processes happen in the absence of a dynamo field. As such, the Moon’s geodynamic evolution, beginning with a magma ocean, subsequent bombardment and extensive mare volcanism has left imprints in the crustal record that can be identified at the surface from imagery and topography, and the subsurface via gravity and magnetic field records. 

Job description

The PhD project aims to leverage existing and publicly available satellite data to investigate the Moon’s evolution recorded in its crust. The central inquiries involve understanding the longevity and evolution of the lunar dynamo and identifying sources responsible for observed crustal magnetization and density anomalies. This knowledge is instrumental in unraveling the underlying geological and geophysical processes that have shaped the Moon’s evolution. By accurately determining the origin and distribution of magnetization, we can better interpret the Moon’s history, tectonic activities, and magnetic dynamo behavior, contributing to a holistic comprehension of its geological past and dynamic characteristics.

Further, we are currently working on a lunar mission proposal and this PhD work will directly aid in understanding interpretability of data collected at the surface. As such it will help our mission to hopefully get to the Moon!
