L1 refers to the Lagrange-1 point in the Sun-Earth system. It is a location in space where the gravitational forces of two celestial bodies, such as the Sun and Earth, are in balance. This allows the object placed there to remain relatively stable with respect to both celestial bodies.
“Jump to the Sun-Earth point L1! The TLI maneuver has been successfully performed. The spacecraft is now on a trajectory that will take it to the Sun-Earth point L1. It will be injected into orbit around L1 through a maneuver after about 110 days. This is the fifth time in a row that ISRO has succeeded in moving an object on a path towards another celestial body or another location in space.
Isro said on Monday that the sensors for the Supra thermal and energy particle spectrometer instrument, which is part of the Aditya… Solar The ASPEX payload has begun measuring ions, ultrathermal electrons, and energy at distances of more than 50,000 kilometers from Earth. This data helps scientists analyze the behavior of particles surrounding Earth.
Once the spacecraft reaches L1, another maneuver will attach Aditya-L1 to an orbit around L1, where it will spend its entire mission period, orbiting in an irregularly shaped orbit in a plane roughly perpendicular to the line connecting the Earth and the Sun.
After its launch on September 2, Aditya-L1 completed its four Earth-bound maneuvers on September 3, 5, 10 and 15. The spacecraft is dedicated to the comprehensive study of the Sun and has seven distinct payloads.
With Aditya-L1, Isro will venture into studying solar activities and their impact on space weather. The scientific objectives of Aditya-L1 include studying coronal heating, solar wind acceleration, coronal mass ejections (CMEs), solar atmospheric dynamics, and temperature variation.
