KPLO KMAG

Korea Pathfinder Lunar Orbiter (KPLO)

KPLO is the first lunar exploration mission in Korea. It is scheduled for launch in August 2022 and its mission life will be one-year. KMAG is one of the instruments on KPLO. KMAG will measure DC and low-frequency magnetic field variations near the lunar surface and provide a 3-D map of lunar magnetic fields. Due to the very limited available volume and mass on the spacecraft, we have adopted the multi-sensor technique to subtract the spacecraft interference field from observational data. Three triaxial fluxgate magnetometers are installed on a 1.2-meter-long boom. Two magnetometers are located at the end of the boom and one is located near the spacecraft-end of boom.
