โœฆ Synopsis

A seismometer placed on Jupiter's moon Europa can use passive monitoring to determine the presence or absence of a possible liquid water ocean beneath Europa's surface ice and estimates of the thickness of the ice shell itself. Using probable seismic velocities for Europa's ice it is demonstrated that surface waves propagating in the frequency band of 0.1 to 0.5 Hz (wave periods of 2 to 10 s) can discriminate ice shells varying from 5 to 20 km in thickness. Miniature, light-weight seismometers with appropriate sensitivities are available.

Magnetic field perturbations measured during Galileo flybys of Europa and Callisto are consistent with dipole fields induced by the temporal variations of the ambient jovian magnetospheric field. These fields are close to those expected for perfectly conducting moons. We investigate the implications
