摘要
遥感观测在用于研究太阳系巨行星的整体大气成分时存在显著局限。这影响了我们对这些行星形成及其大气物理的认知。伽利略探测器对木星的探测阐释了实地探针测量优越性的一个显著例证：诸如惰性气体丰度测定与氦混合比精确测量等关键测量，仅通过伽利略探测器的实地测量才得以实现。在此，我们描述了未来土星、天王星与海王星实地探测所要解决的主要科学目标，并将伽利略探测器对木星的探测置于更广阔背景中。瞄准10巴量级气压层的大气进入探针将揭示两大宽泛主题：i）巨行星与太阳系的形成历史，以及 ii）行星大气中起作用的过程。探针将在降落伞下下降以测量成分、结构与动力学，数据通过作为中继站的载体中继航天器传回地球。大气探针可代表ESA对未来NASA新前沿或旗舰级、发射至土星、天王星和/或海王星的任务的重大贡献。
