Abstract : The Aditya-L1 mission is India’s first dedicated mission to observe the Sun round-the-clock. In addition to the experiments targeted to understand the solar and coronal processes, the mission also includes a number of in-situ experiments. These experiments are Aditya Solar Wind Particle Experiment (ASPEX), Plasma Analyzer Package for Aditya (PAPA) and Magnetometer (MAG). Through these experiments, the solar wind (ions and electrons), supra-thermal and solar energetic particles as well as magnetic field will be measured in multiple directions from the first Lagrangian point (L1) of the Sun-Earth system. Such measurements can throw light on a number of complex processes (like origin, acceleration, seed population, anisotropy etc.) that are not comprehensively understood till date. Understanding on such processes are of paramount importance to connect the solar processes to the space weather conditions prevalent around our planet. The talk will highlight a few such exciting and unresolved scientific issues that can be addressed based on the in-situ measurements and combining these with measurements by other payloads on-board Aditya-L1.
