Aditya-L1 Mission: ISRO Announces Launch Date, 15-Lakh KM Challenge Voyage From Earth

Aditya-L1 Mission: The first space-based Indian observatory to study the Sun. The Aditya-L1 mission, will likely launch by the first week of September, according to ISRO Chief S Somanath. Hours after Chandrayaan-3, ISRO’s third lunar mission, successfully touched down on the moon’s surface, this announcement was made. Aditya L1 will follow AstroSat, which was launched in 2015, as ISRO’s second space-based astronomy mission.

Aditya-1 became the new name for Aditya-1. Only the solar corona was intended for observation by the Aditya 1. Lagrange points are critical locations in space marked by heightened zones of gravitational attraction and repulsion. Influenced by the gravitational interaction between the Sun and the Earth. They are named after the Italian-French mathematician Joseph-Louis Lagrange. These locations have favourable circumstances for spacecraft propulsion.

Aditya-L1 Mission

The Aditya-L1 spacecraft will follow a two-step trajectory while travelling a great distance of 1.4 million kilometres from Earth, or four times the distance to the moon. It will launched into a low Earth orbit at first, and then, using its onboard propulsion system. It will be propelled into a more elliptical orbit that is directed towards the Lagrange point (L1).

Seven different payloads are included in the Aditya-L1 mission, each of which is designed to observe various solar layers such the photosphere, chromosphere, and corona over a range of wavebands. The Visible Emission Line Coronagraph (VELC), created by the Indian Institute of Astrophysics (IIA) in Bengaluru, is one of these payloads. The Inter-University Centre for Astronomy and Astrophysics in Pune also created the Solar Ultraviolet Imaging Telescope (SUIT), which is another component of the mission.

Objective of Aditya-L1

Aditya-L1’s mission is to survey the Sun’s corona and investigate the condition of the solar wind at the Sun-Earth Lagrange point (L1). This spacecraft is equipped to function at a 1.5 million kilometre distance from Earth. The distance between this location and Earth is roughly 1.5 million km. Aditya-L1 will arrive at that position in around 120 days, or 4 months.

India’s first Space Mission Solar Observation

India’s first space mission for solar observation will be this one. The goal of the Aditya-L1 mission is to investigate the Sun from every angle of the L1 orbit. Aditya-L1 will, according to information from ISRO, carry seven payloads that will help with observations of the photosphere (the visible surface of the Sun), chromosphere (the region immediately above the visible surface), and solar corona in various wavelength bands.

Aditya-L1 is entirely indigenous

According to an ISRO source reported by the news agency PTI. Aditya-L1 is totally indigenous and involved the active engagement of national institutions. It has been suggested that when Aditya-L1 reaches the Lagrange point. It may offer important advantages for uninterrupted, continuous Sun observation. This might make it easier to determine in real-time how solar activity and space weather affect things.

About the Aditya L1

Aditya L1 would be the first Indian mission to study the Sun from space. Lagrange point 1, or L1, which is about 1.5 million kilometres from Earth, will be the location of the spacecraft in a halo orbit. The ability to continuously observe the Sun without any occultation or eclipses is the main advantage of having a satellite in the halo orbit around the L1 point. We will have a greater chance to see the solar activity and how it influences the space weather in real time as a result of this. Aditya-L1, the first observatory in orbit for India to study the Sun, was earlier announced by ISRO on Twitter on July 14 and was getting ready to launch.

The extreme temperatures of the corona. Which rise above a million degrees Celsius, in sharp contrast to the Sun’s surface peak temperature of about 6,000 degrees Celsius, are just one example of the phenomena that these payloads are positioned to help us understand.

According to an announcement from ISRO. “The SUITs of Aditya L1 payloads are expected to provide the most crucial information to understand the problem of coronal heating, coronal mass ejection (CME), pre-flare and flare activities and their characteristics. Dynamics of space weather, propagation of particle and fields, etc.”


Aditya-L1 Mission, India’s first dedicated scientific mission to study the Sun, has reached its successful conclusion. Launched by the Indian Space Research Organization (ISRO), Aditya-L1 has provided invaluable insights into the dynamic behavior of our nearest star. Over the course of its mission, Aditya-L1 has gathered data on solar winds, magnetic fields, and other crucial parameters that contribute to our understanding of space weather and its impact on Earth. This mission has not only enhanced our scientific knowledge but also showcased India’s capabilities in space exploration and research. The successful completion of the Aditya-L1 Mission is a testament to India’s commitment to advancing space science and its contributions to global scientific endeavors.

Aditya-L1 Mission FAQ’S

What is L1 in Aditya Mission?

The Aditya L1 mission is set to be the inaugural space-based Indian project dedicated to studying the Sun. According to the ISRO, the spacecraft will be positioned in a halo orbit near Lagrange point 1 (L1) of the Sun-Earth system, which is approximately 1.5 million km away from Earth.

When Aditya-L1 will be launched?

The Indian Space Research Organisation (ISRO) has made an announcement stating that their inaugural solar mission, Aditya-L1, is scheduled for launch on September 2nd at 11:50 am from the Sriharikota space centre. According to ISRO, Aditya-L1 will be stationed at the Sun-Earth Lagrange point L1, situated approximately 1.5 million kilometres away from Earth, where it will conduct observations of the solar corona.

When Aditya-L1 will launch 2023?

The Aditya-L1 solar observatory is scheduled to launch Saturday (Sept. 2) at 2:20 a.m. EDT (0620 GMT; 11:50 local India time), the Indian Space Research Organization (ISRO) announced on Monday (Aug. 28).
