Everyone knows magnets exert forces, but did you know that magnetic fields act a lot like muscles that store and release energy as they tie space plasmas together? Magnetic connections switch in a process called "reconnection" that controls space weather forces and energy flows. The switch occurs in tiny volumes of space called "diffusion regions" where the magnetic field lines take an "X" shape separating magnetic muscles that connect two plasmas from those that do not. MMS will observe how, when and where the magneto-muscular switch occurs and why it is often explosive, especially when one plasma tears free from another.
Based on the MMS launch date of 12 March 2015, the mission schedule calls for commissioning through August 2015, with Phase E beginning 1 September 2015 and running for 36 months, through August of 2018, and likely through the end of FY2017.
