Tumbling Motion Assessment for Space Debris Objects
When Europe still had no access to clarify the attitude of lost spacecrafts in order to optimize recovery attempts and improve re-entry predictions, the precursor GSTP study on ?Attitude Motion Measurements and Modelling? activity paved the way for an independent European capacity in this field. In fact, for the first time in Europe, it was possible to join measurements of SLR, passive telescope and synthetic aperture radar to fit a dynamic attitude model of the given spacecraft.

Space Debris Deflection by Space-Based Laser

The study takes place in the context of the space environment remediation. Tackling the issue of space debris is becoming more and more critical as it becomes more dangerous for existing and future space missions. Solutions must be found to ensure the security of space missions security and a clean space environment. Laser pressure solutions are considered promising as they only using momentum transfer to perform debris manoeuvres to avoid collisions. This means that no additional debris is generated using this technique.

Fast development of kinetic impactor for short-warning asteroid deflection

The study demonstrates that in an emergency situation, with only a very short warning time, the launch of a fast asteroid kinetic deflection mission is feasible (targeting launch-readiness in six months!), given that certain identified pre-requisites have been prepared well in advance. The capabilities and requirements of 'hijacking' and modifying a commercial spacecraft platform in order to perform asteroid kinetic deflection in the shortest possible time were consequently assessed.

Removal of the VESPA upper part

The objective of the Landmark ClearSpace-1 mission will be to demonstrate the complete value chain of active debris removal by removing an ESA-owned object (a VESPA upper part orbiting at an altitude of 500 km) by 2025.
