Aditya L1 completed its fifth and last earth-bound maneuvering in the early hours of Tuesday and is now on send-off from the Earth to Trans-Lagrangian Point 1 Insertion (TL1I).
The Trans-Lagrangian Point 1 Insertion (TL1I) maneuver is the beginning of the spacecraft’s 110-day trajectory to its designated destination of Lagrange Point 1 (L1), a pivotal location with gravitational balance between the Earth and the Sun.
“Off to Sun-Earth L1 point! The Trans-Lagrangean Point 1 Insertion (TL1I) manoeuvre is performed successfully. The spacecraft is now on a trajectory that will take it to the Sun-Earth L1 point. It will be injected into an orbit around L1 through a manoeuvre after about 110 days. This is the fifth consecutive time ISRO has successfully transferred an object on a trajectory toward another celestial body or location in space,” ISRO posted on X (formerly Twitter).
The L1 is 1.5 million km away from the Earth, “there have been many solar observatories located at L1 point, including DSCOVR, WIND, SOHO, and ACE,” reads the NASA website.
