Aditya-L1, an ISRO spacecraft for solar atmosphere study, launched on September 2, 2023, features coronagraphy technology.
In recent instances, the cosmos has grown to be a playground for human exploration, with India making widespread strides in unravelling the mysteries of our celestial neighbour. The Aditya L1 mission, spearheaded by the Indian Space Research Organization (ISRO), marks a historic moment as the state delves into area-primarily based solar statements.
Aditya L1 stands as India’s maiden foray into committed area-primarily based solar commentary. Conceptualised in 2008 through the Advisory Committee for Space Research, the mission seeks to examine the Sun from a near distance, providing unparalleled insights into its atmosphere and magnetic discipline.

Armed with seven present day payloads, Aditya L1 is equipped to look at various sun phenomena, inclusive of the Photosphere, Chromosphere, Solar Corona, sun emissions, solar winds, flares, and Coronal Mass Ejections (CMEs). The spacecraft employs electromagnetic and particle detectors, as well as magnetic discipline detectors, for spherical-the-clock imaging of the Sun
As Aditya L1 embarks on its celestial journey, it aims to dance along the gravitational chessboard, strategically positioning itself at Lagrange Point 1 (L1) of the Sun-Earth system. Here’s List of the distinctive Lagrange Points, where gravitational forces create celestial equilibrium, paving the way for unique observations:
| Lagrange Point | Position in the Sun-Earth System | Characteristics | Notable Satellites |
| L1 | Between the Sun and Earth |
|
|
| L2 | Directly ‘behind’ Earth from the Sun |
|
|
| L3 | Behind the Sun, opposite Earth |
|
|
| L4 and L5 | Forming an equilateral triangle with the two larger bodies |
|
