New Delhi: India’s ambitious space endeavour, Aditya-1, designed to explore the Sun, is all set for liftoff on September 2. ISRO announced the launch timing as 11:50 AM from Sriharikota via a Twitter update.
The public is extended an invitation to witness the momentous event from the Launch View Gallery at Sriharikota. For registration, interested individuals can visit: https://lvg.shar.gov.in/VSCREGISTRATION/index.jsp. The registration commencement date will be announced on the same platform.
Aditya L1 will mark India’s pioneering solar study mission, positioned in a halo orbit around Lagrange point 1 (L1) of the Sun-Earth system, approximately 1.5 million km from Earth. This unique orbit offers uninterrupted views of the Sun, devoid of occultation or eclipses, enhancing the real-time observation of solar activities and their implications on space weather.

The spacecraft accommodates seven distinct payloads equipped with electromagnetic particle and magnetic field detectors. These instruments will facilitate the study of the photosphere, chromosphere, and the Sun’s outermost layers, known as the corona.
ISRO also outlined the mission’s key objectives: “Aditya-L1 aims to study the dynamics of the solar upper atmosphere, including the chromosphere and corona. It seeks to investigate topics such as the heating of the chromosphere and corona, the behaviour of the partially ionised plasma, the initiation of coronal mass ejections and flares, the in-situ particle and plasma environment, and the physics underlying the solar corona and its heating mechanisms.”
Moreover, the mission will delve into the diagnostics of coronal and coronal loop plasma, discerning temperatures, velocities, and densities. It aims to unveil the development, dynamics, and origins of Coronal Mass Ejections (CMEs), decoding the sequential processes leading to solar eruptive events. Magnetic field topology and measurements in the solar corona will also be pursued, along with the exploration of the drivers of space weather, such as the solar wind’s origin, composition, and dynamics.
Preceding this achievement, India celebrated a historic milestone on September 23, as the Chandrayaan-3 lander module flawlessly touched down on the moon’s South Pole. This success concluded the earlier setback of Chandrayaan-2’s crash landing and secured India’s place as the fourth country globally, after the US, China, and Russia, to achieve a successful lunar landing.
