GOALS AND OBJECTIVES CERTIFY BY DIRECT MEASUREMENT THAT PUBLISHED MMS RECONNECTION LAYERS POSSESS ELECTRON GYRO SCALES WHEN DIFFUSION REGIONS WERE SUGGESTED TO HAVE BEEN CROSSED AND THAT COLLISIONLESS DEMAGNETIZATION CAN BE THEORETICALLY UNDERSTOOD. DETERMINE THE STATISTICAL DISTRIBUTION OF SCALES ACROSS ALL SHOCK CROSSING OF THE GI DATA SET TO INVENTORY THE POSSIBLE ROLE OF ELECTRON DEMAGNETIZATION IN IRREVERSIBLE HEATING OF ELECTRONS. SURVEY THE MAGNETOSHEATH TURBULENCE FOR THE INCIDENCE OF ELECTRON GYRO-SCALE CURRENT CHANNELS THOUGHT TO BE IMPORTANT IN TERMINATING THE TURBULENT CASCADE AND OR FACILITATING RECONNECTION IN THE MAGNETO-SHEATH. DETERMINE FREQUENCY OF CONDITIONS FOR RECONNECTION TO BE POSSIBLE IN THE MAGNETO-SHEATH TURBULENCE. WITH THIS PROPOSAL'S MIMSS-METER (MIMSSM) WE DETERMINE MODEL INDEPENDENT LOCAL LENGTH SCALES ACROSS THE ENTIRE GI MMS MISSION DATA SET AND THROUGHOUT THE RESOLVED MAGNETOPAUSE LAYERS CHOSEN FOR EARLY MMS PUBLICATIONS. ONLY THEN CAN THE FULL PROMISE OF MMS BE REALIZED CONCERNING ITS CATALOGUE OF VIOLATIONS OF MHD. MIMSSM: DATA ANALYSIS METHODOLOGY MMSSM REQUIRES CALIBRATED DC ELECTRIC AND MAGNETIC FIELDS THE DENSITY FLOW VELOCITY AND FULL PRESSURE TENSORS OF ELECTRONS AND IONS ACROSS THE PHASE 1 GI DATA SET. MIMSSM DOES NOT REQUIRE (I) FAVORABLE S/C SEPARATION (II) A MODEL PHASE FRONT OR ITS ORIENTATION (III) THE RELATIVE MOTION OF THE OBSERVER ALONG THE PHASE FRONT NORMAL OR (IV) TIME STATIONARITY WHILE TRANSITING MULTIPLE SPACECRAFT. MIMSSM'S OUTPUT IS INDEPENDENT OF FRONT S INFERRED GEOMETRICAL ORIENTATION AND DOES NOT REQUIRE MULTIPLE SPACECRAFT TO SEE THE "SAME" STRUCTURE BEFORE ITS SCALE CAN BE DETERMINED. MIMSSM IS AS MODEL INDEPENDENT AS THE RAW MEASUREMENTS IT USES. MIMSSM HAS BEEN PROOFED USING PIC SIMULATIONS WHERE THE SCALES ARE KNOWN AND HAS BEEN USED WITH POLAR DATA TO DOCUMENT THE FIRST RESOLVED ELECTRON DIFFUSION REGION. MIMSSM IS THEORETICALLY BASED ON THE GENERALIZED OHM'S LAW. IT STATES THAT THE RATIO OF THE SPECIES K REST FRAME ELECTRIC FORCE FE(K) DIVIDED BY THE MAGNETIC FORCE FB(K) ON THE MOST PROBABLE SPEED WK PARTICLE DETERMINES THE RATIO OF THE SPECIES GYRO RADIUS RK DIVIDED BY THE CROSS FIELD SPATIAL SCALE ENCOUNTERED L. RK/L = (C/WK) FE(K)/FB(K) . C IS THE SPEED OF LIGHT. MMSM DETERMINES THE SCALE ENCOUNTERED WHEN FE(K) IS KNOWN L = KT(K)/ FE(K) WHERE KT(K) IS THE PERPENDICULAR TEMPERATURE OF THE K TH SPECIES. IN THE MHD REGIME FE(K) VANISHES CONSISTENT WITH THE INFINITE SCALE LENGTHS THAT UNDERLIES THE MOTIVATION OF MHD. ROUTINELY FE IS AN MMS OBSERVABLE AND WILL YIELD A MEANINGFUL LOCAL SCALE L. MIMSSM WILL ALSO DETERMINE THE DIMENSIONLESS RATE OF WORK EE(K) IN KT UNITS PER GYRO PERIOD TAU(K) BEING DONE ON THE ELECTRONS AND IONS BY THE OBSERVED ELECTRIC FIELDS: EE(K) = TAU(K)(E*UK)/(KT(K)) WHERE UK IS THE SPECIES FLOW VELOCITY KT(K) ITS THERMAL ENERGY AND * DENOTES DOT PRODUCT. EE(K) IS ASSUMED TO BE VERY SMALL IN TRADITIONAL MHD BUT SHOWN IN PIC SIMULATIONS OF RECONNECTION TO BECOME O(1) WITHIN THE EDR AND THUS BECOME AN INDEX OF ALTERNATE WAYS FOR THE COLLAPSE OF MHD EVEN WHEN THE RK/L MIGHT REMAIN SMALL AS IN STRONG GUIDE RECONNECTION OR WITHIN THE BOW SHOCK. MIMSSM WILL ALSO DETERMINE THE SPECIES AGYROTROPY FROM THE PRESSURE TENSOR AS AN INDEPENDENT MEASURE OF DEMAGNETIZATION THAT SHOULD CORRELATE WELL WITH O(1) R_K/L. RELEVANCE GOALS OF MMS: UNDERSTANDING THE KINETIC ELECTRON PHYSICS OF RECONNECTION IS THE PRINCIPAL GOAL OF THE MMS MISSION. THIS IS UNACHIEVABLE WITHOUT MEASUREMENTS OF THE SCALE LENGTHS OF THE CHANNELS WHERE THE REPORTED MORPHOLOGY OCCURS. THIS WILL BE PROVIDED BY MIMSSM. DECADAL SURVEY: "#4: DISCOVER AND CHARACTERIZE FUNDAMENTAL PROCESSES THAT OCCUR BOTH WITHIN THE HELIOSPHERE AND THROUGHOUT THE UNIVERSE" AND ORGANIZING SCIENCE AREA: "5: HELIOSPHERIC PLASMA PROCESSES TURBULENCE WAVES COMPOSITION" MIMSSM PROVIDES THIS THROUGH ALL REGIONS.
