||ADITYA-L1 is an upcoming space based solar observatory of Indian Space Research Organisation. The satellite with seven different instruments, covering multi-wavelength, will be placed in a halo orbit around fist Lagrangian point (L1) of Sun-Earth system. ADITYA-L1 has four remote sensing instruments, viz. Visible Emission Line Coronograph (VELC) to study the corona in visible and infrared range, Solar Ulta-violet Imaging Telescope (SUIT) that observe in NUV range (200nm-400nm) to study photosphere and chromosphere in high spatial resolution, Solar Low Energy X-ray Spectrometer (SoLEXS) and High Energy L1 Orbiting X-ray Spectrometer (HEL1OS) to study sun as a star in X-rays, and three in situ measurement instruments; a magnetometer and two particle detection instruments namely, Aditya Solar wind Particle Experiment (ASPEX) and Plasma Analyser Package for Aditya (PAPA), to study solar energetic particles and plasma. In this presentation an overview of the ADITYA-L1 satellite and it's science objectives will be covered.
