Model representing the space debris environment

ESA maintains and distributes a number of models for the characterisation of the space-debris environment and its evolution. The Agency’s most prominent debris and meteoroid risk assessment tool is MASTER (Meteoroid and Space Debris Terrestrial Environment Reference).

It covers a size regime for debris and micrometeoroids between 0.001 mm and 100 m. The MASTER software can be accessed free of charge via the Space Debris User Portal.
