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

<strong>General information</strong>This dataset is part of the MSc thesis `Consensus-based single-score life cycle assessment for space missions' at Search results | TU Delft RepositoriesAn older version of the dataset was also used for the conference paper `A Consensus-Based Single-Score for Life Cycle Assessment of Space Missions: Preliminary Results', which can be found through the DOI 10.13009/EUCASS2023-571, or on EUCASS's website (www.eucass.eu - EUCASS Full Papers)<br><strong>Abstract of the thesis</strong>With a continuously growing number of satellites in orbit, it becomes increasingly important to assess their impacts on the Earth's environment in a standardised manner. While interest in Life Cycle Assessment (LCA) for space missions has gained in strength in the past few years – particularly in Europe – no consensus has yet been reached on a single-score LCA system. In this thesis, a consensus-based space LCA single-score is created through an international survey of experts. The report demonstrates retroactively the single-score’s use for the ecodesign of the Delft University of Technology’s Delfi-n3Xt space mission. A discussion is also held on ways of implementing the single-score into early design phases. Overall, this thesis highlights the importance of an easy-to-understand LCA tool for space systems. It shows the necessity for a tool that is implementable during the design phase of the mission, to incentivise space actors to further consider environmental impacts.<br><strong>Contents of the dataset</strong>This dataset contains Excel sheets with:the analysed answers of the survey done to reach a consensus on a space LCA single-scorethe results of Delfi-n3Xt's LCAthe calculations made to obtain the recommended weighting factors.<br><strong>Important note:</strong>A specific README.txt file is part of this dataset and is recommended to be read first

<strong>数据集基本信息</strong>本数据集是收录于代尔夫特理工大学（TU Delft）仓储库（Search results | TU Delft Repositories）的硕士论文《Consensus-based single-score life cycle assessment for space missions》（《面向航天任务的基于共识单分值生命周期评估》）的配套数据集。该数据集的旧版本曾用于会议论文《A Consensus-Based Single-Score for Life Cycle Assessment of Space Missions: Preliminary Results》（《面向航天任务生命周期评估的基于共识单分值：初步成果》），可通过DOI 10.13009/EUCASS2023-571或EUCASS官网（www.eucass.eu - EUCASS 官方论文页面）获取。<br><strong>论文摘要</strong>随着轨道卫星数量持续增长，以标准化流程评估其对地球环境的影响愈发关键。近年来，航天任务生命周期评估（Life Cycle Assessment, LCA）的关注度持续攀升，尤以欧洲地区为甚，但目前尚未形成统一的单分值LCA体系。本研究通过面向全球专家的国际调研，构建了基于共识的航天LCA单分值体系。本研究回溯验证了该单分值体系在代尔夫特理工大学Delfi-n3Xt航天任务生态设计中的应用，并探讨了将该单分值体系融入任务早期设计阶段的可行路径。总体而言，本研究强调了面向航天系统的易懂型LCA工具的重要性，并指出需开发可在任务设计阶段落地的工具，以激励航天相关主体进一步重视环境影响考量。<br><strong>数据集内容</strong>本数据集包含以下Excel表格：1. 为达成航天LCA单分值共识所开展的专家调研分析结果；2. Delfi-n3Xt航天任务的生命周期评估结果；3. 用于推导推荐权重因子的相关计算数据。<br><strong>重要说明</strong>本数据集包含专属README.txt文件，建议优先阅读该文件。
