Orbital Debris Modeling

Orbital Debris Research Image NASA scientists continue to develop and upgrade orbital debris models to describe and characterize the current and future debris environment. Engineering models, such as ORDEM 3.0, can be used for debris impact risk assessments for spacecraft and satellites, including the International Space Station and the Space Shuttle. Whereas, evolutionary models, such as LEGEND, are designed to predict the future debris environment. They are reliable tools to study how the future debris environment reacts to various mitigation practices.
