The DAMAGE computer model predicts the space debris population will grow exponentially despite widespread implementation of mitigation measures, with a high concentration of space debris developing near an altitude of 1,400km. These findings indicate that our space activity is unsustainable and that new management policies are needed.
Hugh Lewis is a Professor of Astronautics in the Faculty of Engineering and Physical Sciences at the University of Southampton.
He has been active in the space debris research community for more than 20 years, is the author of the space debris model DAMAGE and he currently chairs the Inter-Agency Space Debris Coordination Committee’s (IADC) Working Group on space debris modelling. In 2011, he was nominated as the UK’s representative to the Expert Group on Space Debris, which reported to the United Nations Committee on the Peaceful Uses of Outer Space (COPUOS) Scientific and Technical Subcommittee (STSC) Working Group on the Long-term Sustainability of Outer Space Activities.
