New Delhi: In another historic moment for India in space, Aditya-L1 — the country’s first mission to study the sun — has reached its final destination. The space observatory was launched by the Indian Space Research Organisation (ISRO) on September 2 last year.
Praising the country’s scientists for the achievement, Prime Minister Narendra Modi said India has created yet another landmark and that the country will pursue new frontiers of science to benefit humanity.
In a post on X on Saturday, the PM wrote, “India creates yet another landmark. India’s first solar observatory Aditya-L1 reaches its destination. It is a testament to the relentless dedication of our scientists in realising among the most complex and intricate space missions. I join the nation in applauding this extraordinary feat. We will continue to pursue new frontiers of science for the benefit of humanity.”
The success comes months after India scripted history with the Chandrayaan-3 mission, becoming the only nation to achieve a successful soft landing near the south pole of the Moon.
Aditya L1, which is India’s first space-based observatory to study the Sun, has been placed in a halo-shaped orbit around the Sun-Earth Lagrange Point 1. The point is around 1.5 million km from the Earth, in the direction of the Sun.
Lagrange points, named after French mathematician and astronomer Joseph-Louis Lagrange, are unique locations in space where the gravitational force of two massive bodies nearly neutralise each other. Maintaining the orbit of spacecraft around these points is easier and requires less fuel.
ISRO chairman S Somanath said Aditya L1 has been placed precisely in the orbit and that the prediction of the velocity requirement was correct. “Based on our calculations, it is in the right place. We will monitor for a few hours and make corrections, if necessary. We don’t expect that to happen.”
“Understanding the Sun is not important for India alone, Adiya-L1 is also for the whole of the world. We look forward to scientific outcomes. At least five years of life is guaranteed with the fuel left in the satellite,” he added.
From its vantage point around L1, the solar observatory will have a continuous and uninterrupted view of the sun for the next five years. With Chandrayaan-3, XPoSAT and Aditya L1, India has hit a celestial hat-trick in its quest to better understand the solar system and the universe.
