In a historic milestone for India’s space exploration efforts, the Indian Space Research Organisation (ISRO) has achieved the successful launch of its maiden solar observatory mission, Aditya-L1, dedicated to unraveling the secrets of the Sun.
This momentous event occurred at 11:50 am IST at the Satish Dhawan Space Centre in Sriharikota, Andhra Pradesh. Notably, Aditya-L1 embarked on one of the lengthiest missions ever undertaken by the Polar Satellite Launch Vehicle, separating from the rocket’s fourth stage nearly an hour after liftoff.
Aditya-L1’s primary objective is to closely study the Sun and its dynamic activities from a unique vantage point approximately 1.5 million kilometers away from Earth. Positioned in a halo orbit around Lagrange point 1 (L1) in the Sun-Earth system, this strategic location ensures uninterrupted observations of the Sun, providing real-time data on solar phenomena and space weather.
The mission is equipped with seven specialized scientific instruments, including the Visible Emission Line Coronagraph (VELC), Solar Ultraviolet Imaging Telescope (SUIT), Aditya Solar wind Particle Experiment (ASPEX), and Plasma Analyser Package for Aditya (PAPA).
These instruments will facilitate multi-wavelength observations of the Sun’s atmosphere, aiding in the understanding of energy and matter flow between its various layers.
Aditya-L1’s significant objectives include deciphering the mystery of the Sun’s corona, which is notably hotter than its surface, and investigating the processes behind solar flares, coronal mass ejections (CMEs), and solar energetic particle (SEP) events.

These insights will bolster space weather forecasting, benefiting communication systems, satellites, and power grids. Additionally, the mission aims to explore the long-term effects of the Sun’s radiation on Earth’s climate by studying near-UV solar radiation and its impact on the upper atmosphere.
The successful launch of Aditya-L1 represents a remarkable stride in India’s space exploration journey, promising groundbreaking discoveries in solar and heliophysics. It enhances our comprehension of the Sun’s behavior and its interactions with Earth and the broader space environment, offering invaluable insights for future research and applications.
