Deflecting dangerous asteroids
Providing scientific evidence for the possibility of deflecting an asteroid by external bombardment

Head of Science Programme
Providing scientific evidence for the possibility of deflecting an asteroid by external bombardment

Developing a database composed of simple estimates and a large number of pre-processed simulations of probable impact scenarios

The project investigates Earth's evolution after the Moon's formation, from magma ocean to habitable planet, using impact research and numerical modelling.
The MEMIN network investigates impact processes through interdisciplinary lab experiments with light-gas guns and numerical modelling of impact craters.

The subproject improves the numerical modelling of impact events through more realistic material models and the integration of meso- and macroscale simulations.
