In a monumental achievement for India’s space program, the country successfully launched its first solar observatory satellite into low Earth orbit last Saturday. The Indian Space Research Organization (ISRO) confirmed that the Aditya-L-1 spacecraft was launched from India’s Satish Dhawan Space Center on a Polar Satellite Launch Vehicle, marking a significant stride in India’s space exploration endeavors. The ISRO proudly announced that the satellite has been precisely placed into its intended orbit, commencing its journey to the Sun-Earth L1 point, a location about 1 million miles from Earth.

The Aditya-L-1 satellite is not just India’s first solar observatory, but it’s also an ambitious project designed to orbit and observe the sun directly from the Lagrange point 1. This spacecraft is equipped with seven payloads, four of which are dedicated to remote sensing of the Sun, while the remaining three are designed for in-situ observation. Once in its orbit around the sun at L1, the spacecraft will use its instruments to study various solar phenomena such as solar flares, coronal mass ejections, and solar wind, providing crucial insights into the functioning of our solar system’s most vital star.

India’s First Solar Observatory Satellite, Aditya-L1, Successfully Launched

India’s Space Research Organization (ISRO) announced a successful launch of its first solar observatory satellite, the Aditya-L1, into low Earth orbit. The launch was performed from the Satish Dhawan Space Center using the Polar Satellite Launch Vehicle (PSLV-C57). This marks a significant achievement in India’s space program, furthering its exploration and understanding of the universe.

A Precise and Unique Mission

"The launch of Aditya-L1 by PSLV-C57 is accomplished successfully," ISRO announced. "The vehicle has placed the satellite precisely into its intended orbit." The spacecraft is designed to leave low Earth orbit for a location about 1 million miles from Earth, known as the Lagrange point 1 (L1). This unique mission mode involved the upper stage of the PSLV taking two burns for the primary satellite for the first time, as mentioned by ISRO chairman Sreedhara Panicker Somanath.

Observing the Sun with Aditya-L1

At the L1 point, the Aditya-L1 will directly orbit and observe the Sun. It carries a total of seven payloads, four for remote sensing of the Sun and three for in-situ observation. The instruments are primarily tuned to observe the solar atmosphere, specifically the chromosphere and corona. Furthermore, the Aditya-L1 will study solar phenomena such as solar flares, coronal mass ejections, and solar wind, thereby contributing to our understanding of these solar activities.

A Milestone for India’s Space Program

Indian Prime Minister Narendra Modi hailed the Aditya-L1 launch as another milestone for India’s space program. "After the success of Chandrayaan-3, India continues its space journey," he said. "Congratulations to our scientists and engineers at ISRO for the successful launch of India’s first Solar Mission, Aditya-L1."

This launch follows the successful landing of the Vikram lander near the Moon’s south pole last month as part of India’s Chandrayaan-3 mission. The lander carried the Pragyan lunar rover, which has since demonstrated its ability to navigate parts of the lunar surface.


The successful launch of Aditya-L1 not only marks a significant achievement for India’s space program but also contributes to the global efforts in understanding the Sun and its activities. The data gathered from this mission will help scientists study solar phenomena, which has implications on Earth’s climate and our preparedness for solar events. This highlights the importance of international cooperation and investment in space exploration for the benefit of humanity.
