MMS Payload

MMS Quick Facts
 • Launched 3/12/2015
 • Solving Magnetospheric
    Reconnection, and
    Turbulence (SMART)
    is the MMS Science
 • Southwest Research
    Institute (SWRI)
    is leading the
    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.
