<b>Abstract</b>:</div>
<div style="font-family:Arial,Helvetica,sans-serif; font-size:12pt; color:black">
NASA’s InSight mission operated on Mars from 2018 until the end of 2022 and has documented over 1200 seismic shakes and quakes. Seismic shakes that originated from small meter-sized fresh cratering events allowed us to infer the structure of the top crust on
Mars. The InSight’s seismic survey and interior mapping, followed by the crustal structure and thermal evolution modelling made in the last few years, allowed for a better understanding of the ancient impact bombardment on Mars that formed the largest craters
on the planet. This seminar will focus on numerical impact modelling of both small and large impact bombardment on Mars, including how numerical modelling assists in placing constraints on the interior structure of early Mars via impact basins and estimates
the location of ice layers in the shallow crust via the largest fresh ice-exposing crater ever discovered. It reviews some of the impacts-related science delivered during and after the NASA InSight science operations.</div>
