Aditya-L1
India's First Dedicated Solar Mission
Aditya-L1 is the Indian Space Research Organisation's (ISRO) first dedicated mission to study the Sun, launched to observe the solar corona, chromosphere, solar wind, and space weather phenomena from a vantage point unobstructed by Earth's shadow.
- Launched on 2 September 2023 aboard a PSLV-C57 rocket; inserted into a halo orbit around the Sun-Earth Lagrange Point 1 (L1) on 6 January 2024
- L1 is located about 1.5 million km from Earth (roughly 1% of the Earth-Sun distance), a point where the gravitational pull of the Sun and Earth balance, allowing continuous, uninterrupted observation of the Sun
- Carries seven payloads, including VELC (Visible Emission Line Coronagraph, built by IIA Bengaluru — the primary instrument for imaging and spectroscopy of the corona), SUIT (Solar Ultraviolet Imaging Telescope), SoLEXS, HEL1OS, ASPEX, PAPA, and a magnetometer (MAG)
- Mission objectives include studying coronal heating, CMEs, solar flares, solar wind acceleration, and space weather effects that can impact satellites, communication, and power grids on Earth
