- Understand coronal conditions under which the shocks form and determine the interplanetary conditions where they evolve.
- Characterize Identify interplanetary shocks and characterise their spatial and temporal evolution. Characterize shock structure , and determine whether they are locally quasi-perpendicular or quasi-parallel, and study kinetic properties of shock-related waves and turbulence that control ion scattering mean free paths near the shock. [IS only]
- Study heating and dissipation mechanisms at shocks with radial distance.
- Infer the rates of particle acceleration and the injection energies as a function of distance and along different parts of the shock. [IS only; radial dependence; multiple orbits]
