Cosmic Dust in the Solar System

Abstract

This course provides students with a basic understanding of the science of cosmic dust in the solar system and how to measure it with space-based satellites and instrumentation. The lectures include the physical processes of both interplanetary and interstellar dust, trajectory simulations (i.e. orbital dynamics), in situ measurement techniques, and mission design aspects.

Objective

Cosmic dust is an important building block for planets and towards life. This course provides students with a basic understanding of the science of cosmic dust in the solar system, and how to measure it with space-based satellites and instrumentation. The lectures include the physical processes of both interplanetary and interstellar dust, trajectory simulations (i.e. orbital dynamics), in situ measurement techniques, and mission design aspects. At the end of the course, students are able to classify the different types of dust in the solar system, and to relate them to their sources, sinks, their importance for planetary science and astronomy, physical processes, and appropriate measurement techniques. They will be able to simulate dust trajectories and use them to gain insight in how orbital dynamics and the space environment shape them. Students can design a basic concept of a space mission for dust measurements. The skills taught in this course will be useful to students in a broader way for planetary sciences.
