Aditya L1: India’s historic solar mission to launch today

India’s Pioneering Solar Mission: Aditya L1 Set for Launch

India is all set to take a historic leap in space exploration with the launch of its mission to study the Sun, named Aditya L1. Aditya L1, led by the Indian Space Research Organization (ISRO), will launch from the Sriharikota Space Center on September 2 at 11:50 am.

  • Launch Venue: The mission will be launched today at 11:50 am from SriHarikota Space Center exclusively through PSLV C57 rocket.
  • L1 Lagrange Point: Aditya L1 will be positioned in a halo orbit around the Lagrange Point L1, situated approximately 1.5 million kilometers from Earth, within the Sun-Earth system. This unique location capitalizes on the gravitational equilibrium between the Sun and Earth, making it an ideal vantage point for solar observations.

Countdown Progress:

As the launch time approaches, meticulous preparations are underway at the control center at the Satish Dhawan Space Center in Sriharikota. ISRO officials have confirmed that the countdown is going smoothly, setting the stage for the important launch.

Media Coverage:


This historic event attracted considerable attention, with over 200 journalists present to cover every aspect of the launch. Additionally, the viewing gallery outside the Satish Dhawan Space Center is witnessing a rapid influx of attendees who had earlier registered to witness this remarkable satellite launch.

Mission Objectives:

Aditya L1’s primary mission is to uncover the secrets of the Sun, focusing on the study of the solar wind and the Sun’s atmosphere. It is equipped with seven payloads designed to observe important aspects of the Sun, including the photosphere, chromosphere and the outermost layer called the corona. These observations will help in a deeper understanding of phenomena such as coronal heating, coronal mass ejections, pre-flare and flare activities as well as solar weather dynamics. Additionally, Aditya L1 will study the propagation of particles and fields in the interplanetary medium, which will provide valuable insights into space weather.

Significance of Lagrange Points:


Lagrange points, including L1, are important locations in space named in honor of the Italian-French mathematician Joseph-Louis Lagrange. Of the five Lagrange points, L1 holds a special status, because it lies along the line connecting two massive celestial bodies (in this case, the Sun and the Earth). The deployment of Aditya L1 at this point underlines the precision and innovation behind this mission.

Global Space Exploration Landscape:

With the launch of Aditya L1 mission, ISRO joins the ranks of prestigious space agencies like NASA, European Space Agency (ESA), Japan Aerospace Exploration Agency (JAXA) and Chinese Academy of Sciences in pursuit of solar observations. Objective. This is an important step forward for India’s space exploration efforts, contributing to the global understanding of our Sun.

In conclusion, the Aditya L1 mission is a testament to India’s growing strength in space exploration. As the satellite sets out on its journey to study the Sun, it not only strengthens India’s position in the global space community but also promises to uncover the secrets of our solar system’s star. The successful implementation of this mission will undoubtedly be a source of pride and knowledge for the nation.
