Séminaire de Thème — The Present-day Structure and Evolution of Mars

Séminaires thème Intérieurs de la Terre et des planètes

Also on zoom here: On November 26, 2018, the InSight probe landed on Mars' Elysium plain and deployed instruments on the surface of the Red Planet to measure seismic activity, heat flow, magnetic field and precise rotation. The mission collected data for almost four years of operation, until December 2022. I will discuss the interpretation of this data with a focus on the seismic recordings. For the latter, unlike the Earth and Lunar networks, the InSight seismic experiment consists of a single station to record multiple seismic events for the first time at the surface of Mars. This required the development of approaches tailored to take best advantage of this particular configuration in order to characterise the current structure of Mars as well as its thermal and chemical history. I will present these aspects and summarise the state of knowledge that the interpretation of these data have taught us about Martian evolution. Also on zoom here:
