FIELDS on MMS

Science Goals

MMS Payload



MMS Quick Facts
 • Launched 3/12/2015
 • Solving Magnetospheric
    Acceleration,
    Reconnection, and
    Turbulence (SMART)
    is the MMS Science
    Investigation
 • Southwest Research
    Institute (SWRI)
    is leading the
    multi-institutional
    science investigation.
    The team...
 • Mission duration:
    2yrs. 6mos.
 • Four spacecraft will fly
    in tetrahedral formation
    through regions of
    the magnetosphere,
    each collecting data
    with identical suites
    of instrumentation.
