After the historic and groundbreaking achievement of Chandrayaan-3, the Indian Space Research Organisation (ISRO) has successfully launched the Aditya-L1 mission, placing India’s first solar space observatory into orbit.
The mission, carried out by the Polar Satellite Launch Vehicle (PSLV-C57), represents a significant step forward in India’s space exploration efforts and promises to provide crucial insights into our nearest star, the Sun.
Aditya-L1 Mission Overview:
The Aditya-L1 mission, named after the Sun god “Aditya” in Hindu mythology, is India’s pioneering solar space observatory. The primary objective of this mission is to study the Sun and gather vital data about its outermost layer, the solar corona.
The solar corona plays a crucial role in understanding the Sun’s behavior, solar storms, and space weather, which can have significant impacts on Earth and its technological infrastructure.
The launch of the Aditya-L1 mission took place on September, 2nd, 2023, at 11.50 am from the Satish Dhawan Space Centre in Sriharikota, India. ISRO’s reliable PSLV-C57 rocket was selected for this mission, known for its precision and versatility in delivering payloads into various orbits.
It was PSLV’s 59th flight and 25th mission with an XL configuration. The launch marked a momentous occasion for India’s space program, solidifying its reputation as a spacefaring nation. The payload- Aditya-L1 spacecraft weighing 1,480.7kg will continue its 4-month-long journey before settling in the Lagrange L1 halo orbit which is 1.5 million km from the Earth.
The Prime Minister of India, Narendra Modi congratulated ISRO on the successful launch of solar mission along with the country, claiming the success as everyone’s. “Our tireless scientific efforts will continue in order to develop better understanding of the universe for the welfare of entire humanity,” he said on ‘X.’

Instrumentation and Objectives:
The Aditya-L1 spacecraft is equipped with a suite of advanced scientific instruments designed to observe the Sun and its corona. These instruments include:
Visible Emission Line Coronagraph (VELC): VELC is a high-resolution imaging telescope that will capture images of the solar corona in visible light. It will help scientists study the dynamics and magnetic fields in the corona, providing insights into solar activities like solar flares and eruptions.
Solar Ultraviolet Imaging Telescope (SUIT): SUIT is designed to observe the Sun’s ultraviolet emissions. It will focus on capturing images of the Sun’s chromosphere, providing valuable data on temperature variations and dynamics in this critical region.
Plasma Analyser Package for Aditya (PAPA): PAPA is tasked with measuring the particle flux in the solar wind. Understanding the solar wind’s composition and variations is vital for comprehending space weather and its impacts on Earth.
Significance of the Mission:
The Aditya-L1 mission holds immense scientific and practical significance. By studying the Sun’s corona and solar activities, it will contribute to our understanding of space weather, which can affect communication systems, navigation, and power grids on Earth. This knowledge is crucial for space agencies and industries worldwide.
Additionally, Aditya-L1 will advance our knowledge of the Sun’s influence on Earth’s climate and atmospheric conditions. Solar variability plays a role in Earth’s climate patterns, and studying the Sun is key to understanding long-term climate changes.
The Aditya-L1 mission represents a collaboration between ISRO and international space agencies and research institutions. Sharing data and insights about the Sun’s behavior and space weather is essential for the global scientific community to mitigate the impacts of solar events on Earth and space-based technologies.
The successful launch of the Aditya-L1 mission by ISRO is a significant milestone in India’s space exploration journey. This solar space observatory promises to deepen our understanding of the Sun, space weather, and their impacts on our planet.
With advanced instrumentation and international collaboration, Aditya-L1 is poised to make groundbreaking discoveries about our nearest star, enhancing both scientific knowledge and our ability to manage space-related challenges on Earth.
