India successfully launched its first mission to study the sun on September 2, 2023, just days after its successful moon landing. The mission, called Aditya-L1, is named after the Hindu god of the sun, Aditya. It is a solar observatory that will be placed in a halo orbit around the Lagrange point 1 (L1), which is a point between the sun and Earth where the gravitational forces of the two bodies are balanced.
Aditya-L1 is equipped with seven payloads to study the sun’s corona, chromosphere, photosphere, and solar wind. The mission is expected to help scientists better understand the sun’s activity and its impact on Earth’s atmosphere and climate.

The launch of Aditya-L1 is a major milestone for India’s space program. It demonstrates India’s growing capabilities in space science and technology. The mission is also a significant contribution to the international effort to study the sun.
Here are some of the key objectives of the Aditya-L1 mission:
- Study the sun’s corona, the outermost layer of the sun’s atmosphere, which is much hotter than the surface of the sun.
- Study the sun’s chromosphere, the layer of the sun’s atmosphere that lies just below the corona.
- Study the sun’s photosphere, the layer of the sun’s atmosphere that we see from Earth.
- Study the solar wind, the stream of charged particles that flows from the sun.
- Understand the sun’s activity and its impact on Earth’s atmosphere and climate.
The Aditya-L1 mission is expected to last for five years. It is a complex and challenging mission, but it has the potential to make significant advances in our understanding of the sun.
