The solar mission is really important for India as after space agencies like NASA and the European Space Agency (ESA), India will be the first country and is all ready for the solar mission

This will help India study Sun's upper atmosphere (chromosphere and corona) and its interaction with the solar wind. The mission is aimed at studying the physics of the partially ionized plasma in the solar atmosphere.

The spacecraft will investigate the mechanisms that heat the solar corona and observe the initiation and development of coronal mass ejections (CMEs) and solar flares.

It will study the in-situ particle and plasma environment in the vicinity of the Sun and characterise the magnetic field in the solar corona.

It will also study and evaluate the main drivers of space weather.

Hence this is an ambitious mission for India, as it is a challenge of stationing a craft at a Lagrange point, which India has not done before.

There are five Lagrange points in space where gravity of the two closest objects in the solar system interact in such a way that a spacecraft placed at any of these will remain stable there (usually in a small orbit). Aditya-L1, as its name implies, will be stationed at the L1 point, the closest of the five Lagrange points, and also one from which an unhindered view of the Sun is possible.

Second, the nature of new insights that the spacecraft can bring. It will carry seven payloads, including four to observe the Sun’s outermost layers — known as the photosphere and chromosphere — by using electromagnetic and particle field detectors.
