The Magnetospheric Multiscale (MMS) Mission is a NASA robotic space mission to study the Earth's magnetosphere, using four identical spacecraft flying in a tetrahedral formation.[1] The spacecraft were launched on 13 March 2015 at 02:44 UTC.[2] The mission is designed to gather information about the microphysics of magnetic reconnection, energetic particle acceleration, and turbulence — processes that occur in many astrophysical plasmas.[3] As of March 2020, the MMS spacecraft has enough fuel to remain operational until 2040.[4]
