Space debris mitigation requirements specific to propulsion systems are scrutinized and compliance of OHB reference propulsion architectures is assessed. The risk of generating debris due to a failure in a propulsion system is assessed with a focus on the specific risk of a hypervelocity impact on a propulsion tank containing residuals.

The engineering activities, delta-qualifications or hardware development which can support the recommended propulsion passivation strategies are presented and prioritized.

The contract work is in collaboration with OHB System, the Swedish Defence Research Insti- tute (FOI), Inmarsat, and Etamax.
