ULF Waves on Mars During One Martian Year: Preliminary Results 

Kyle Webster

Mars may not always have been the dry planet it is today . There is not only evidence for the existence of water on ancient Mars, but also there are traces of surface water on Mars today . What about beneath the surface of Mars? Is there groundwater below the surface like there is on Earth? 




The InSight mission arrived at Mars in late 2018, and it has the tools to sound the interior of Mars. Even though seismic activity is the primary interest of the mission, InSight also carries the first ever magnetometer to be on the surface of Mars. Mars does not have a dynamo driven global magnetic field, however many regions on the surface are magnetized by the local crustal magnetization of the rocks. InSight can measure variations in the crustal magnetic field associated with changing ionospheric currents, which exhibit wave-like oscillations with periods of ~ 50 - 1000 seconds. These waves can penetrate into the interior of Mars, where we can search for the existence of groundwater.
