The Aditya L1 Mission is a pioneering space mission undertaken by the Indian Space Research Organisation (ISRO) to study the Sun. Launched in 2022, Aditya L1 is India’s first dedicated solar mission, aiming to explore the outermost layer of the Sun’s atmosphere, known as the corona.
It carries a suite of advanced instruments designed to observe and analyze various aspects of the Sun, including its magnetic field, solar winds, and ultraviolet emissions. By studying the Sun, Aditya L1 aims to enhance our understanding of solar phenomena and their impact on space weather, which can affect satellite communications, power grids, and other critical technologies on Earth.
Aditya L1 Mission List
Aditya-L1, derived from the Sanskrit word “आदित्य” meaning Sun, is a dedicated coronagraph spacecraft aimed at investigating the solar atmosphere. This cutting-edge satellite has been meticulously crafted through the collaborative efforts of the Indian Space Research Organisation (ISRO) and several prominent Indian research institutions.
Positioned approximately 1.5 million kilometers away from Earth, Aditya-L1 will be stationed in a halo orbit encircling the L1 Lagrange point, strategically positioned between the Earth and the Sun. Its primary mission objectives encompass the study of the solar atmosphere, solar magnetic storms, and their influence on the terrestrial environment.
List of Aditya L1 Mission Objective
- Study of Solar upper atmospheric (chromosphere and corona) dynamics
- Study of chromospheric and coronal heating, physics of the partially ionized plasma, initiation of the coronal mass ejections, and flares
- Observe the in-situ particle and plasma environment, providing data for the study of particle dynamics from the Sun
- Physics of the solar corona and its heating mechanism
- Diagnostics of the coronal and coronal loop plasma: Temperature, velocity, and density
- Development, dynamics, and origin of CMEs
- Identify the sequence of processes that occur at multiple layers (chromosphere, base, and extended corona) that eventually leads to solar eruptive events
- Magnetic field topology and magnetic field measurements in the solar corona
- Drivers for space weather (origin, composition, and dynamics of solar wind)

ISRO Aditya L1 Solar Mission New Updates
The inaugural solar mission of India, Aditya L1, commenced its journey triumphantly as the launch vehicle took off from Sriharikota, Andhra Pradesh. Annapurni Subramaniam, the Director of the Indian Institute of Astrophysics in Bengaluru, highlighted that this mission will be the pioneering endeavor to explore the Sun’s innermost realm – the Corona.
In a conversation with ANI just prior to the launch of India’s first solar mission, Subramaniam stated, “We have successfully integrated the primary instrument, the Visible Line Emission Coronagraph (VELC), onto the launch vehicle carrying Aditya L1. This instrument will provide an uninterrupted view of the Sun.”
“Its unique capability lies in its continuous observation of the Sun in an eclipse-like state. Aditya L1 will be the inaugural mission to scrutinize the Sun’s innermost region, the Corona,” she further explained.
