Which ISRO mission is related to the SWIS and STEPS instruments?

In recent months, two state-of-the-art particle spectrometers have started collecting data, allowing India's Aditya L1 satellite to start solving mysteries surrounding the solar wind. The Aditya Solar Wind Particle Experiment payload's SWIS and STEPS instruments have found protons, helium ions, and energy histograms displaying variations in solar wind behavior close to Sun-Earth Lagrange Point L1. The 360-degree coverage and directional monitoring capabilities of SWIS will greatly advance our understanding of the characteristics, variability, and connections between Earth-influencing space weather and the solar wind. As Aditya L1 approaches the L1 orbital point for continuous solar observation, scientists eagerly await more discoveries to answer long-standing questions about the intricate solar wind and corona heating.
