Technology for Self Removal of Spacecraft (TeSeR)
Start date: 01 Feb 2016, End date: 31 Jan 2019 PROJECT  FINISHED 

Orbital space is getting increasingly crowded and a few collision events could jeopardize activities in important orbits and cause significant damage to the infrastructure in space. As a preventive measure to be included in future S/C, TeSeR proposes a universal post mission disposal module to be carried into orbit by any S/C to ensure its proper disposal after ending its service lifetime, be it planned or unscheduled due to S/C failure. This module shall be independent of the S/C.Principal aims of TeSeR are to1. develop a removal module beginning with the exploration of concepts, going for a functional design with the aim to manufacture and test an on-ground prototype module which demonstrates the main functions2. perform a thorough qualitative and quantitative mission analysis of existing removal concepts3. develop a ground breaking new semi-controlled removal concept based on a passive removal concept which ensures the deorbit of a large S/C (>1 t) into the Pacific Ocean without a propulsion system but with an accuracy of a fraction of one orbit4. advance and manufacture removal subsystems prototypes, for controlled, semi-controlled and uncontrolled disposal, based on already existing technology with the focus on scalability and standardized implementation to the removal module via a common interface5. analyse the feasibility and potential advantages of multi-purpose concepts of the module and its removal subsystems (e.g. shielding by deployable structures)6. perform a market study and define a business case for TeSeR7. use TeSeR as leverage to propose changes in legal aspects and advanced state of the art licensing standard for spacecraft including the improvement of international debris mitigation guidelines and standards
