On Saturday, the Satish Dhawan Space Centre in Sriharikota successfully launched an ISRO spacecraft. With this, India took a step towards finishing its first solar trip. The spacecraft will be positioned on the L1 spot in the halo orbit surrounding the Sun after a four-month voyage. Today’s launch occurred at 11:50 a.m. from Sriharikota’s Satish Dhawan Space Centre.


Aditya-L1 is a satellite intended for in-depth research on the Sun. It contains 7 different payloads that were all created separately. 5 by ISRO and 2 by academic institutions working with ISRO in India.

Sanskrit refers to the Sun as Aditya. Lagrange Point 1 belonging to the Sun-Earth system is referred to as L1 here. The forces of gravity between two celestial objects, like the Earth and the Sun, are in balance at L1, according to conventional thought. This makes it possible for an object to stay stable about both of the celestial bodies.

Aditya-L1 is positioned strategically at the L1 Lagrange point so that it may keep a steady, continuous view of the Sun. The satellite can observe solar rays and magnetic storms from this position without being affected by the magnetic field or atmosphere of Earth.

Aditya-L1 will continue to orbit the Earth at a distance of 1.5 million kilometers (1%) of the distance between the Earth and the Sun. The Sun is a huge sphere of gas, and Aditya-L1 would study the outer atmosphere.

How it works 

  • The seven payloads of the spacecraft will be dispersed across the Sun. Lagrange point 1 (L1), where the satellite will be deployed, will be in a halo orbit. 
  • The main benefit of having that satellite in the halo orbit is that it will be able to monitor the Sun instead of any occultation or eclipses.
  • The spacecraft’s other payloads will be used by its electromagnetic, particle, and magnetic field detectors to monitor the photosphere, chromosphere, and the Sun’s outermost layers (the corona). 
  • The remaining three payloads will conduct in-situ particle and field research near the Lagrange point L1, while the remaining four payloads will observe the Sun directly.

To learn more about the Sun’s atmosphere, the Aditya L1 satellite is fitted with a variety of instruments, such as:

  • An image of visible light
  • Near-infrared imager
  • A far-UV imager.
  • Solar spectrometer
  • Heliospheric imaging device

These instruments will make it possible for researchers to conduct in-depth studies of the Sun’s atmosphere.

Scientists will be able to research the Sun’s magnetic field, heat, and composition. Additionally, they will be able to research sunlight flares and other space-related phenomena.

Along with its scientific advantages, the Aditya L1 launch includes a lot of economic and societal advantages. 

Aditya L1 satellite development has increased employment and improved the Indian economy. 

The Aditya L1 satellite’s data will be utilized to create innovative technologies, which will help the Indian economy grow even more. 

The Aditya L1 project will also contribute to advancing our knowledge about the Sun, which is crucial to protecting existence on Earth.

A significant milestone for both India and the world is the launch of the Aditya L1. It demonstrates both India’s dedication to scientific inquiry and its expanding capacity for space exploration. 

The Aditya L1 mission is anticipated to significantly advance our knowledge of the Sun and its effects on Earth while also assisting in the protection of life on Earth against solar storms as well as other space weather occurrences.
