Answer:
Hey there! So, you know how the Earth has a magnetic field that surrounds it, right? Well, that magnetic field is called the magnetosphere.
Scientists are really interested in studying the magnetosphere because it helps protect us from the sun's harmful radiation. It's kind of like an invisible shield that keeps us safe.
So, to learn more about the magnetosphere, scientists use a special set of satellites called the Magnetospheric Multiscale (MMS) mission. These satellites help us measure things like the strength and direction of the magnetic field, the temperature of particles in the magnetosphere, and how different parts of the magnetosphere interact with each other.
By studying the magnetosphere using the MMS satellites, scientists can learn more about how it works and how it protects us from the sun's harmful radiation. This can help us better understand space weather, which can affect things like our satellites and power grids on Earth.
