Analysis of Enceladus’s Time-variable Space Environment to Magnetically Sound its Interior

open access: yesThe Planetary Science Journal
We provide a comprehensive study of Enceladus’s time-variable magnetic field environment and identify in measurements of the Cassini spacecraft signatures that appear to be consistent with induced fields from the moon’s interior.
