Abstract

A method for computing self-contamination processes of a spacecraft involves receiving a first set of input parameters comprising general definitions of the spacecraft, and a second set of input parameters comprising control parameters for the spacecraft orbital data, physics, numeric. A self-contamination process of the spacecraft is calculated based on the received first and second sets of input data by calculating an analytical solution of a basic equation for calculating a deposit of molecules outgassed from surfaces of the spacecraft in a single computation step with the data processing device. The calculated deposit of molecules is then output.
