Adity-L1 To Be Launched On Sept 2. Here's How To Register To Watch ISRO Solar Mission's Launch From Sriharikota

Aditya-L1: India's based first space-based observatory to study the Sun will be launched atop a Polar Satellite Launch Vehicle (PSLV) on September 2, at 11:50 am IST, from Sriharikota.

Aditya-L1, which will be launched on September 2, 2023, is India's first space-based solar mission, and its launch can be witnessed from the Launch View Gallery at Sriharikota, Andhra Pradesh. People interested to watch the launch of the Indian Space Research Organisation's (ISRO's) upcoming mission can register themselves at https://lvg.shar.gov.in/VSCREGISTRATION/index.jsp.

ISRO has announced that registration is expected to be enabled from August 29, 2023, at 12:00 pm IST.

India's based first space-based observatory to study the Sun will be launched atop a Polar Satellite Launch Vehicle (PSLV) on September 2, at 11:50 am IST, from Sriharikota. The spacecraft will be placed in a halo orbit around the Lagrange point 1 (L1) of the Sun-Earth system, in order to reduce fuel consumption, and to ensure that Aditya-L1 has an unobstructed view of the Sun. Lagrange points are special points in space where spacecraft remain fixed, enabling energy conservation.

L1 is a unique Lagrange point because not only will it allow Aditya-L1 to save its fuel, but will also provide an uninterrupted view of the Sun to the spacecraft. This means that Aditya-L1 will not witness any occultations or eclipses during its five-year mission duration.

Aditya-L1 will study solar dynamics, and the different layers of the Sun's atmosphere, which include the corona, chromosphere and photosphere. The observatory will also analyse the particles and fields at L1, which is located 1.5 million kilometres from Earth, in order to see how solar dynamics affect the interplanetary medium.

Aditya-L1 is equipped with seven payloads. These will study coronal mass ejections, solar flare activities, propagation of particles and fields, the problem of coronal heating, the physics of solar corona, the mechanisms which lead to different conditions of space weather, the sequence of processes that occur at different layers above the Sun, the magnetic field dynamics in the solar corona, and coronal plasma, which includes ionised particles.
