Description
As the space sector faces unprecedented growth and scrutiny regarding its environmental footprint and space debris risks, the need for actionable, standardized space sustainability guidelines has never been more critical. This presentation introduces the first version of the Handbook on Sustainable Practices of Space Mission Design, developed at the EPFL Space Center. Unlike previous theoretical frameworks, this handbook serves as a pragmatic bridge between high-level sustainability goals and concrete engineering decisions, addressing sustainability for space (terrestrial impact) and in space (orbital preservation).
The handbook distinguishes itself through its holistic lifecycle approach, integrating Life Cycle Assessment (LCA) methodologies specifically adapted for space systems with operational best practices for debris mitigation, Dark & Quiet Skies preservation, and end-of-life strategies. A core novelty of this work is the inclusion of a comprehensive hardware decision tree, designed to guide system engineers and mission managers in selecting specific technologies—such as low-debris separation mechanisms, design-for-demise materials, passive detumbling devices, and standardized mechanical interfaces for in-orbit servicing. This tool transforms abstract sustainability metrics into tangible design requirements, facilitating the trade-off analysis necessary for early-phase mission planning.
Drawing on the latest ESA guidelines, ISO standards, and emerging industry consensus (including the Space Sustainability Rating), this presentation will highlight the handbook’s structure. It will demonstrate how the decision tree aids in making responsible design choices against orbital congestion and terrestrial impact while maintaining mission viability. The presentation will also emphasise the future evolutions of the Handbook, relying on industry feedback. By providing a centralized reference for students, engineers, and decision-makers, the EPFL Handbook on Sustainable Practices of Space Mission Design aims to standardize sustainable design practices across the space ecosystem, ensuring that future missions are not only technically feasible but environmentally responsible.
