What is it about?
Rocks retain a magnetic memory at the time of their formation, called magnetic remanence. Remanence preserves information about ancient magnetic fields. We use an unpiloted aerial vehicles (UAV) and a magnetic sensor to map some of the largest magnetic remanence values on earth.

Why is it important?
This study is important for setting up a workflow to carry out magnetic mapping in remote environments, such as planetary studies and to highlight the challenges operating UAVs in areas with highly magnetic rocks.
