Mars gravity change
Job description

Observations done by InSight have resulted in new information about the Martian lithosphere and confirmed that the core is liquid. This new evidence raises the question: Is the planet still geologically active? The largest volcanic complex in our solar system can be found on Mars. After fifty years of orbiting satellites it is still unclear if the Tharsis complex is dynamically supported by a mantle plume. The goal of this PhD project is to investigate the possibility of active mantle plume dynamics underneath the Tharsis Region by using satellite gravity-rate observations.

To prepare for this work, a state-off-the-art lithosphere/geodynamical model of the Martian mantle and crust will be developed and inserted in a 3D geodynamical code (ASPECT) to study the plume-lithosphere interactions. Rigorous testing and development scheme is designed to fully understand the model results. The numerical modelling will be completed by a thorough parameter search of the Martian mantle-lithosphere structure and various plume scenarios will be tested.

Additionally, we propose to search in the past 50 years of satellite gravity data, the secular gravity change signature of the plume uplift at the Tharsis Rise. This will be done by a re-analysis of all available tracking data with a TU Delft-developed astrodynamical toolbox Tudat.

The project builds on an earlier Research in our group that developed a model based on lithosphere flexure, gravity field modelling and mantle convection studies. This model can be extended to simulate realistic interior structures and calculates decade long changes in the gravity field and surface of Mars. Observations of several Mars orbiting satellites should be compiled for a long period gravity change map, to validate the geophysical model. The PhD project is supported by a team of international scientists with expertise on observations and modelling of Mars. Funding includes computer and necessary software and travel to conferences as well as research visits to project
