Abstract MAP-PACE (MAgnetic field and Plasma experiment-Plasma energy Angle Composition Experiment) is one of the scientific instruments onboard SELENE (SELenological ENgineering Explorer) satellite. PACE consists four sensors: ESA (Electron Spectrum Analyzer)-S1, ESA-S2, IMA (Ion Mass Analyzer), IEA Energy Analyzer). ESA-S1 S2 measure distribution function low-energy electrons below 15 keV, while low ions 28 keV/q. Each sensor has a hemispherical view. Since three-axis stabilized spacecraft, pair electron sensors (ESA-S1 S2) ion (IMA IEA) are necessary for obtaining three-dimensional ions. The objectives (1) to sputtered from lunar surface atmosphere, (2) magnetic anomaly on using two ESAs magnetometer simultaneously as an reflectometer, (3) resolve Moon-solar wind interaction, (4) Moon-Earth’s magnetosphere (5) observe Earth’s magnetotail.
