The Indian Space Research Organisation (ISRO) is set to launch its Aditya-L1 mission today, September 2, 2023. The mission is a first-of-its-kind for India and will study the Sun from a closer vantage point than ever before.
The Aditya-L1 spacecraft will be placed in a halo orbit around the Sun-Earth Lagrange point 1 (L1), which is located about 1.5 million kilometers from Earth. This orbit will allow the spacecraft to continuously observe the Sun without any obstructions.
The mission is expected to provide valuable insights into the Sun’s atmosphere, magnetic field, and solar wind. This information will help scientists better understand the Sun’s role in space weather and its impact on Earth.

What is the L1 point?
The Sun-Earth Lagrange points are five points in space where the gravitational forces of the Sun and Earth balance each other out. This allows objects to stay in orbit around the L1 point without any propulsion.
The L1 point is located directly between the Sun and Earth, about 1.5 million kilometers from Earth. It is a unique location in space that allows for continuous observation of the Sun without any obstructions.
What will Aditya-L1 study?
The Aditya-L1 spacecraft will carry seven payloads to study the Sun’s atmosphere, magnetic field, and solar wind. The payloads include:
- A coronagraph to image the Sun’s corona, the outermost layer of the Sun’s atmosphere.
- A spectrometer to measure the Sun’s composition and temperature.
- A magnetometer to measure the Sun’s magnetic field.
- A particle detector to measure the solar wind.
The data from these payloads will help scientists better understand the Sun’s dynamics and its impact on space weather.
Why is it important to study the Sun?
The Sun is the most important star in our solar system. It provides us with light and heat, and it also plays a role in space weather. Space weather is the activity on the Sun that can affect Earth’s atmosphere and magnetic field. This activity can cause solar flares, coronal mass ejections, and other events that can disrupt communication systems, power grids, and satellites.
By studying the Sun, scientists can better understand its role in space weather and develop ways to mitigate its effects on Earth.
The benefits of India’s Aditya-L1 mission
The Aditya-L1 mission is a significant milestone for India’s space program. It is the first Indian mission dedicated to studying the Sun, and it will provide valuable data that can be used to improve our understanding of the Sun and its impact on Earth.
The mission is also expected to create new opportunities for scientific collaboration between India and other countries. The data from the Aditya-L1 mission will be shared with scientists around the world, and it will help to advance our understanding of the Sun.
