Magnetospheric Multiscale (MMS) Mission Updates – September 4, 2015

MMS Officially Begins Science Phase

NASA's Magnetospheric Multiscale, or MMS, mission successfully completed commissioning activities on Sept. 1, 2015, and is now in full science mode.

During the next six months, the four MMS spacecraft will fly in a tetrahedral formation that will skim Earth's magnetopause near every apogee, sampling that boundary and the myriad of plasma processes that occur there. The primary focus for the MMS science team will be one of the most important and least understood of those processes: Magnetic Reconnection. Magnetic reconnection occurs when magnetic fields around Earth connect and disconnect, explosively releasing energy.
