Data for MSc Thesis: `Consensus-based single-score life cycle assessment for space missions

The fast growth of satellite launches means we need clear ways to measure how space missions affect the environment. Life Cycle Assessment (LCA) methods are being used more in aerospace, but we still lack a single, agreed‑upon score that can summarize all the impacts. This research aims to create and test a consensus‑based single‑score LCA framework made for space missions. We will gather structured feedback from international aerospace and environmental experts. The idea is to combine many different environmental impact categories into one easy‑to‑use number. That number can help engineers make ecodesign choices early in mission planning. To show how the framework works, we will apply the single‑score model to

the life‑cycle data of Delft University of Technology’s Delfi‑n3Xt satellite mission. The analysis will look at how different weighting schemes and the experts’ consensus change the identification of environmental hotspots in the manufacturing, launch, and orbital‑operations phases. The project offers practical guidance for using single‑score LCA in aerospace engineering. It gives a systematic way to balance multiple environmental trade‑offs and to bring sustainability directly into the early design of space systems.
