India’s Historic Journey Towards the Sun
India marked a historic milestone in its space exploration journey as the maiden flight mission to the Sun, Aditya L1, successfully took off from the Sathish Dhawan Space Centre Sriharikota. This remarkable event occurred at precisely 11:50 am and signifies a major leap forward in India’s space endeavors.
Liftoff to the Sun
The PSLV C57 rocket, carrying Aditya L1, soared into the clear skies on a sunny afternoon, creating a reverberating sound that resonated with the crowds at ISRO (Indian Space Research Organisation). The excitement was palpable, with whistles and claps filling the air. Scientists at the Control Centre exchanged smiles as the rocket embarked on its journey.
Continuing India’s Ambitious Pursuit
India’s mission to the Sun comes on the heels of the successful Chandrayaan-3 mission. The PSLV C57 used for this mission is the XL variant, equipped with longer strap-on motors and a higher fuel quantity. All flight parameters were in perfect order, ensuring a smooth launch.

The Journey Ahead
Approximately 51 minutes after liftoff, the first signal was received from the shipborne terminal, marking the beginning of tracking the second part of the fourth stage. Aditya L1 is set to reach the Lagrange 1 point in about four months. This point is where the gravitational forces of a two-body system like the Sun and Earth create enhanced regions of attraction and repulsion.
Aditya L1’s mission focuses on studying the solar winds and the Sun’s atmosphere. It carries seven payloads designed to observe various aspects of the Sun, including the photosphere, chromosphere, and the outermost layer known as the Corona. These observations are critical for understanding phenomena like coronal heating, coronal mass ejections, pre-flare and flare activities, weather dynamics, and the propagation of particles and fields in the interplanetary medium.
India’s successful mission to the Moon in August was quickly followed by this journey to the Sun. This achievement puts India in an elite group of spacefaring nations. Four other space centers around the world have also embarked on missions to explore the Sun, underscoring the global interest in understanding our nearest star.
ISRO’s Impressive Track Record
ISRO’s contributions extend beyond India’s borders. They not only orbit India’s own satellites but have launched hundreds of foreign satellites from 36 different countries since 1999, primarily utilizing the reliable PSLV rocket. Notably, the PSLV rocket holds the record for placing 104 satellites into orbit in a single flight, showcasing its efficiency and versatility.
India’s journey towards the Sun is not only a testament to the nation’s growing capabilities in space exploration but also a significant step towards unraveling the mysteries of our solar system. This mission highlights India’s commitment to advancing scientific knowledge and fostering international cooperation in the realm of space exploration.
