Mathematics for Planetary Defense

Speaker

Prof. Giacomo Tommei, University of Pisa - Department of Mathematics

Abstract

Planetary defense consists of monitoring and protecting the Earth from dangers coming from space, including asteroids and comets. Mathematics is fundamental in such activity, through the Orbit Determination (OD) and Impact Monitoring (IM) tools. 
In this lecture we will focus on the mathematical methods to perform the OD and IM of Near-Earth Objects, highlighting the challenges for the future and showing some insights from the Hera mission.
