欧洲空间局（ESA）冰质木卫探测器（JUICE）将于2031年探测木卫四十四（Kallichore）

木星（Jupiter）拥有众多卫星，其中伽利略卫星（Galilean moon）因其活跃的地质活动而备受关注。然而，天文学家（astronomer）认为，木星那些较小且鲜为人知的卫星，对于研究太阳系（solar system）的历史具有重要价值。

The planet Jupiter hosts more than 100 moons with the majority of attention going to the four Galilean moons, Io, Europa, Ganymede, and Callisto. This is primarily due to their active geology, including Io being the most volcanically active planetary body in the solar system and Europa having a vast subsurface liquid water ocean beneath its icy crust. However, Jupiter’s smaller and lesser-known moons could provide astronomers key insights into the history of the solar system since they’ve remained largely unchanged, unlike the Galilean moons.
