The space surrounding our planet is densely populated by an increasing number of man-made space debris, most of which have been generated from the break-up of operational satellites, abandoned spacecraft or upper stages of launchers. Space debris is internationally recognised as a hazard to current and future space activities and space agencies are currently cooperating to identify appropriate and sustainable space debris mitigation measures.

A number of these challenges were addressed by the project “Space Debris Evolution, Collision risk, and Mitigation” SpaceDebECM.

An Intra-European Fellowships (IEF) under the framework FP7-PEOPLE-2011-IEF was awarded to Dr. Camilla Colombo for a two year project (1 June 2013 to 31 May 2015) at the Department of Aerospace Science and Technology at Politecnico di Milano Politecnico di Milano.

The first objective of the SpaceDebECM ; project is to investigate the orbital dynamics of space debris through semi-analytical techniques as they allow a deeper insight into the orbit debris evolution under the effect of natural perturbations in the Earth environment. The second objective of SpaceDebECM is to design ways for end-of-life removal of space debris and assess the effectiveness of any proposed mitigation strategy. Finally, the SpaceDebECM project addresses the problem of the modelling of large clouds of small debris fragments and the computation of the resulting collision probability. The SpaceDebECM project is organised in the following Tasks:

Task 1: Space debris evolution;

Task 2: Collision;

Task 3: Space debris mitigation.
