| Abstract : | The first Indian Solar and Heliospheric Observatory, Aditya-L1, was launched on 2nd September 2023. The mission is currently in cruise phase and expected to reach the L1 orbit (Lagrangian 1 of Sun-Earth system) in the month of Jan 2024. The primary science objective of the mission is to understand the solar dynamics, especially the chromospheric and coronal dynamics of the Sun and its influence at L1 which in turn provides information about the disturbances which potentially reaches Earth. To accomplish this, Aditya-L1 carries four remote sensing and three in-situ experiments. The remote sensing experiments include: (i) Visible Emission Line Coronagraph (VELC), (ii) Solar Ultra-violet Imaging Telescope (SUIT), (iii) Solar Low-Energy X-ray Spectrometer (SoLEXS), and (iv) High Energy L1 Orbiting Spectrometer (HEL1OS). Along with the remote sensing payloads, there are three in-situ experiments to measure the in-situ plasma, particles, and magnetic field dynamics. The in-situ experiments are: (i) Plasma Analyser Package for Aditya-L1 (PAPA), (ii) Aditya Solarwind Particle EXperiment (ASPEX), and (iii) MAGnetometer (MAG).
In this presentation, Aditya-L1's science capabilities as a stand-alone mission and also synergetic with other missions or observatories will be highlighted. A glimpse of Aditya-L1's capabilities from the preliminary observations will be shown. As an observatory for the solar and heliospheric community, mode of national and international community participation through science proposals with Aditya-L1 will be explained. |
