Within the Aditya-L1 mission's ASPEX payload, what is the primary scientific role of the Solar Wind Ion Spectrometer (SWIS)?

Explanation

SWIS is a crucial component of the ASPEX payload on India's Aditya-L1 mission. Its primary scientific role is to analyze solar wind by measuring the energy, flux, and directional distribution of low-energy ions, particularly protons and alpha particles. This data is essential for understanding solar wind dynamics and how solar particles interact with the interplanetary medium, providing vital insights into space weather and solar-terrestrial relationships.
