Satellites collect information on wind speed and particle density for use in making predictions about the solar wind and possible solar storms.

卫星收集有关风速和粒子密度的信息，用于预测太阳风和可能发生的太阳风暴。

So when we go to Jupiter, for example, with a flyby mission, we are taking pictures of Jupiter, we're measuring the magnetic field, the particle density, and we're basically exploring remotely.

所以当我们去木星时， 例如，执行飞越任务，我们正在拍摄木星的照片， 我们正在测量磁场， 粒子密度，我们基本上是在远程探索。
