The Lagrange point for Aditya-L1 was fixed by scientists at the Indian Space Research Organisation (ISRO). They used a combination of mathematical calculations and computer simulations to determine the optimal location for the spacecraft.

The Lagrange point is a location in space where the gravitational forces of two celestial bodies, such as the Sun and Earth, are in equilibrium. This allows an object placed there to remain relatively stable with respect to both celestial bodies.

To fix the Lagrange point, ISRO scientists first calculated the gravitational forces of the Sun and Earth at different points in space. They then used computer simulations to model the motion of a spacecraft at different locations. By running many simulations, they were able to identify the location where the spacecraft would remain in a stable orbit around the Lagrange point.

Once the Lagrange point was fixed, ISRO scientists then designed a trajectory for Aditya-L1 to reach the point. The spacecraft was launched on September 2, 2023, and is expected to reach the Lagrange point in November 2023.

To maintain its orbit around the Lagrange point, Aditya-L1 will need to perform small periodic maneuvers. This is because the spacecraft is constantly being affected by small perturbations in the gravitational field, such as from other planets and asteroids.

Aditya-L1 is India's first dedicated solar mission. It will carry seven payloads to study the Sun in different wavelengths, from the photosphere to the corona. The mission is expected to provide new insights into the Sun's interior, atmosphere, and magnetic field.
