Constellation that investigated Earth's magnetosphere
The Magnetospheric Multiscale (MMS) mission is a Solar Terrestrial Probes Program mission within NASA’s Heliophysics Division. The MMS mission, consisting of four identically instrumented spacecraft, uses Earth’s magnetosphere as a laboratory to study magnetic reconnection, a fundamental plasma-physical process that taps the energy stored in a magnetic field and converts it—typically explosively—into heat and kinetic energy in the form of charged particle acceleration and large-scale flows of matter.
