Indian Space Research Organisation announce the launch date of its next Aditya-L1 solar mission following the successful Chandrayaan-3 mission to the Moon. India’s first solar mission, will study the Sun and is schedule for lift-off on 2nd September 2023 at 11:50 am from the Sriharikota spaceport.
ISRO said that its Aditya-L1 mission, design to study the Sun, has complete launch rehearsals and internal checks.
The Aditya-L1 spacecraft is equip for remote observations of the solar corona and in-situ observations of the solar wind at L1(Sun-Earth Lagrange point), locate approximately 1.5 million kilometres from Earth.
This mission is of huge significance as it will provide insights into the Sun’s dynamics and its impact on space weather.
The L1 point is a unique location in space where the gravitational forces of the Sun and Earth create regions of enhance attraction and repulsion.
Aditya-L1 Spacecraft position at these Lagrange points can efficiently maintain their orbits with minimal fuel consumption, as per NASA.
Aditya-L1 is a fully indigenous effort with the involvement of national institutions, including the Indian Institute of Astrophysics and the Inter-University Centre for Astronomy and Astrophysics in Pune.
The mission will utilise a PSLV-C57 rocket for its launch. Aditya-L1 carries many specialise payloads design to observe different aspects of the Sun, including the photosphere, chromosphere, and corona, across various wavelengths.

Some of the key science objectives of the mission include studying the dynamics of the solar upper atmosphere, investigating the heating of the chromosphere and corona, understanding coronal mass ejections, and examining space weather drivers.
Aditya-L1 position in a halo orbit around the L1 point, it will have continuous visibility of the Sun without any planetary interference or eclipses.
This advantageous position will provide real-time monitoring of solar activities and their effects on space weather.
This mission’s instruments are finely tune to observe the Sun’s atmosphere and in-situ instruments will capture data from the local environment at L1 point.
