The Indian Space Research Organization (ISRO) has announced that the Aditya L1 Solar Observatory spacecraft will be launched on 2 September 2023 at 11:50 AM IST from Andhra Pradesh’s Sriharikota.

Update: The Aditya L1 has launched successfully as per the schedule marking a major achievement in ISRO’s journey of space exploration.

Users interested in watching the PSLV-C57 rocket launch from the Launch View Gallery in Sriharikota can sign up on ISRO’s official website:

The PSLV XL rocket of ISRO will launch the Aditya-L1 mission from Sriharikota’s Satish Dhawan Space Center (SDSC-SHAR). The spacecraft will first be positioned in a Low Earth Orbit. 

The orbit will become more elliptical, and the spacecraft will use onboard propulsion to launch itself toward the Lagrange point (L1).

What are the Objectives of the Aditya-L1 Solar Mission?

Seven payloads will be carried by the Aditya L1 mission to observe the photosphere, chromosphere, and corona in various wavebands.

The Indian Institute of Astrophysics (IIA) Bengaluru created and built the expedition’s Visible Emission Line Coronagraph (VELC) payload.

The Inter-University Centre for Astronomy and Astrophysics, Pune, developed the Solar Ultraviolet Imaging Telescope (SUIT), which is similar.


These will aid ISRO in gathering information about how Corona’s temperature can exceed a million degrees while the sun’s surface temperature peaks at over 6000 degrees Celsius.

The objectives of Aditya L1 Mission are:

  • Physics of solar corona and its heating mechanism.
  • Study of Solar Upper Atmospheric Dynamics.
  • Drivers for space weather.
  • Observe the in-situ particle and plasma environment.
  • Identify the processes that occur at multiple layers that cause solar eruptive events.
  • Development, dynamics, and origin of CMEs.
  • Magnetic field topology and magnetic field measurements in the solar corona.
