为欧罗巴快船的推进油箱做准备
Contamination control engineers in a clean room at the Goddard Space Flight Center evaluate a propellant tank before it is installed in our Europa Clipper spacecraft. The tank is one of two that will be used to hold the spacecraft’s propellant. It will be inserted into the cylinder seen at left in the background, one of two cylinders that make up the propulsion module.
With an internal global ocean under a thick layer of ice, Jupiter’s moon Europa may have the potential to harbor existing life. Europa Clipper will swoop around Jupiter on an elliptical path, dipping close to the moon on each flyby to collect data. Understanding Europa’s habitability will help scientists better understand how life developed on Earth and the potential for finding life beyond our planet. Europa Clipper is set to launch in 2024.

在戈达德太空飞行中心的洁净室里，污染控制工程师在推进剂燃料箱安装到欧罗巴快船之前对其进行评估。这个燃料箱是用来装载飞船推进剂的两个燃料箱之一。它将被插入背景左侧的圆柱体中，这是组成推进模块的两个圆柱体之一。
由于木星的卫星木卫二内部有一片覆盖着厚厚的冰层的海洋，可能存在生命。欧罗巴快船将沿椭圆形轨道绕木星飞行，欧罗巴快船将以椭圆路径围绕木星飞行，每次飞越时都会靠近木卫二以收集数据。了解木卫二的可居住性将有助于科学家更好地了解地球上的生命是如何发展的，以及在地球之外发现生命的可能性。欧罗巴快船计划于2024年发射。
