The Suprathermal and Thermal Ion Composition (STATIC) instrument is part of the Particles and Fields (P and F) Package and measures thermal ions to moderate energy escaping ions.
Goals:
Measure the source ion populations near periapsis, the heated ionospheric ions at intermediate altitudes that achieve escape velocity, and the pickup acceleration of these ions in the magnetosheath and solar wind
Allow direct measurements of the Martian sheath plasma, separating shocked solar wind and planetary ions that populate the sheath and plasma sheet
