Aditya L1: ISRO's solar mission set for 4-month Journey to Lagrange point

While travelling towards L1, Aditya L1 will exit the earth’s gravitational Sphere of Influence.
Once out of it, its "cruise phase" will begin and the craft will be injected into a large halo orbit around L1. “ The total travel time from launch to L1 would take about four months for Aditya-L1," the ISRO said. Lagrange points represent specific locations in space where the gravitational forces of two celestial bodies, such as the Sun and Earth, generate regions of gravitational balance.
Within these points, a spacecraft can maintain a stable position without the need for continuous fuel consumption.

Among these, L1 and L2, positioned closest to the Earth, offer advantageous positions for conducting observational investigations.
