'Off To Sun-Earth L1 Point': Aditya-L1 Exits Earth's Gravitational Sphere Of Influence, To Reach Destination After 110 Days

<p>Aditya-L1 has successfully performed the Trans-Lagrangean Point 1 Insertion (TL1I) manoeuvre, the spacecraft's fifth and final Earth-bound manoeuvre. The perigee burn was performed on September 19, 2023, at 2:00 am IST. After the manoeuvre, Aditya-L1 is on a trajectory that will take it to the Sun-Earth Lagrange Point 1 (L1). Also, the spacecraft has exited Earth's gravitational sphere of influence (SOI).&nbsp;</p> <p>India's first space-based solar observatory to study the Sun will reach its destination, which is a halo orbit around L1, after about 110 days, through a manoeuvre. Aditya-L1 is set to begin the cruise phase of its voyage. After Aditya-L1 successfully performed the fifth Earth-bound manoeuvre, the Indian Space Research Organisation (ISRO) wrote on X (formerly Twitter): "Off to Sun-Earth L1 point!"</p> <p>The TL1I manoeuvre marks the fifth consecutive time ISRO has successfully transferred a spacecraft on a trajectory towards another celestial object or location in space.&nbsp;</p> <p>Aditya-L1 has also commenced its scientific experiments.</p>
