LUMIO Phase B weak stability boundary transfers

The Lunar Meteoroid Impacts Observer (LUMIO) is a 12U-XL cislunar CubeSat. LUMIO shall observe, quantify, and characterize meteoroid impacts on the lunar farside by detecting their flashes, complementing Earth-based observations. The Phase B of the mission, funded by ESA under the General Support Technology Programme (GSTP), through the support of the national delegation of Italy (ASI) and Norway (NOSA), kicked off in September 2022 and successfully ended in October 2023. During the Phase B, weak stability boundary (WSB) transfers have been selected as baseline solution for LUMIO to reach the operational halo orbit after a release by a mothercraft of a translunar trajectory. This dataset has been created to store some possible transfers from the Earth to the operational quasi-halo orbit computed during the Phase B. The dataset is made of two items: A compressed folder containing 52 different plain text files. Each file contain a transfer for each week of year 2027; A SPK SPICE kernel ('LUMIO_WSBTranfer_Example.bsp'), containing the transfer of week 20 and its associated operational orbit. The kernels covers LUMIO trajectory from release (20 MAY 2027) to the end of the operational phase (24 AUG 2028). LUMIO SPICE ID is -1000009.月球流星体撞击观测器（Lunar Meteoroid Impacts Observer, LUMIO）是一款12U-XL型地月空间立方体卫星（CubeSat）。LUMIO将通过探测流星体撞击产生的闪光，对月球背面的流星体撞击事件开展观测、量化与特征刻画工作，以此弥补地基观测无法覆盖月球背面的盲区。 该任务的B阶段由欧洲空间局（European Space Agency, ESA）在通用支持技术计划（General Support Technology Programme, GSTP）框架下资助，并获得意大利国家航天局（Agenzia Spaziale Italiana, ASI）与挪威国家航天局（Norwegian Space Agency, NOSA）的支持，于2022年9月正式启动，2023年10月顺利完成。在B阶段研发过程中，项目组选定弱稳定边界（Weak Stability Boundary, WSB）转移作为LUMIO脱离母船后，沿地月转移轨道抵达任务运行晕轨道的基准解决方案。 本数据集旨在存储B阶段期间计算得到的、若干条从地球至任务运行准晕轨道的转移轨道相关数据。数据集包含两部分内容： 1. 一个压缩文件夹，内含52个纯文本文件，每个文件对应2027年某一周的一条转移轨道； 2. 一个SPK型SPICE内核文件（`LUMIO_WSBTranfer_Example.bsp`），其中包含第20周的转移轨道及其对应的运行轨道。该内核覆盖了LUMIO从2027年5月20日释放至任务运行阶段结束（2028年8月24日）的全部飞行轨迹。LUMIO的SPICE标识编号为-1000009。
