The Europa Jupiter System Mission (EJSM) is the major Outer Planet Flagship Mission in preparation by NASA. Although well designed, the current EJSM concept may present problematic issues as a Flagship Mission for a long-term exploration program that will occur over the course of decades. For this reason, the present work reviews the current EJSM concept and presents a new strategy for the exploration of Europa. In this concept, the EJSM is reorganized to comprise three independent missions focused on Europa. The missions are split according to scientific goals, which together will give a complete understanding of the potential habitability of Europa, including in situ life's signal measurements. With this alternative strategy, a complete exploration of Europa would be possible in the next decades, even within a politically and economically constrained environment.
木卫二木星系统任务（EJSM）是美国宇航局正在筹备的主要外行星旗舰任务。尽管设计精良，但作为一个将在未来几十年内进行的长期探索计划的旗舰任务，当前的 EJSM 概念可能会带来一些问题。出于这个原因，本研究回顾了当前的 EJSM 概念，并提出了一种探索木卫二的新策略。在这个概念中，EJSM 被重新组织为三个独立的任务，专注于木卫二。这些任务是根据科学目标划分的，它们将共同全面了解木卫二的潜在宜居性，包括对原位生命信号的测量。通过这种替代策略，即使在政治和经济受限的环境下，未来几十年内也有可能对木卫二进行全面探索。
