Interplanetarymedium monitoring with LISA: Lessons from LISA Pathfinder

The Laser Interferometer Space Antenna (LISA) of the European Agency (ESA) will be first low-frequency gravitational-wave observatory orbiting Sun at 1 AU. LISA Pathfinder (LPF) mission, aiming testing instruments to located on board spacecraft (S/C), hosted, among others, fluxgate magnetometers and a particle detector as parts diagnostics subsystem. These allowed us estimate magnetic Coulomb spurious forces acting test masses that constitute mirrors interferometer. With these instruments, we also had possibility study galactic cosmic-ray short term-term variations function energy associated interplanetary disturbances. Platform detectors placed each S/C. This work reports an empirical method disentangle onboard-generated components field by using LPF magnetometer measurements. Moreover, number fluence solar energetic events expected observed with ESA Next Generation Radiation Monitor during mission lifetime. An additional detector, similar designed for LPF, in combination magnetometers, would permit observe evolution recurrent non-recurrent increases Interplanetary Magnetic Field transit high-speed wind streams counterparts coronal mass ejections. subsystem makes this natural multi-point space weather science investigations.
