But you can make multiple passes through points where the creature intersects its own body.

但是你可以多次通过生物与自己身体相交的点。

Measurements of Ganymede's magnetic field, made during multiple passes by the Galileo spacecraft in the 1990s, combined with Hubble observations of the moon, indicate Ganymede has quite a bit of salty liquid water, deep beneath its surface!

上世纪90年代，伽利略号宇宙飞船多次经过木卫三并发回它的磁场数据，加上哈勃望远镜的观测，结果都表明木卫三的地表下藏有相当多的含盐液态水！
