Aditya L1 Mission Highlights: The Indian Space Research Organisation (ISRO)’s ambitious debut mission to study the Sun, Aditya L1, will reach its final destination on Saturday at 4pm. ISRO will perform the final manoeuvre on Saturday to inject Aditya-L1 spacecraft — the first space-based Indian observatory to study the Sun.
Aditya L1 will be injected into its final destination orbit near the Sun, some 1.5 million kilometres from the Earth.
The Polar Satellite Launch Vehicle (PSLV-C57) launched the Aditya-L1 spacecraft from the second launch pad of Satish Dhawan Space Centre (SDSC), Sriharikota, on 2 September in 2023.
After a flight duration of 63 minutes and 20 seconds, it was successfully injected into an elliptical orbit of 235×19500 km around the Earth.

Result of PM’s inspiration and hard work of our scientists, says BJP’s CP Joshi
Rajasthan Bharatiya Janata Party president CP Joshi extended his wishes to the Indian Space Research Organisation (ISRO) scientists on Saturday after the Aditya-L1 spacecraft, the nation’s first dedicated solar mission, entered its final destination orbit.
Aditya-L1 has reached Lagrange Point L1, about 1.5 million km from earth. Last September, the PSLV-C57.1 rocket carrying the Aditya-L1 lifted off successfully from the Satish Dhawan Space Centre in Sriharikota, Andhra Pradesh.
“Aditya L1 sent on India’s solar mission, reached its destination L1 point today. Congratulations and best wishes for this. Best wishes to Indian scientists on this extraordinary achievement. The success of the campaign is the result of the inspiration of the successful Prime Minister and the tireless hard work of the scientists,” he said. (ANI)

Aditya L1 ISRO’s first Sun mission LIVE: Trivia on Sun
Sun, a hot glowing ball of hydrogen and helium gases, is the nearest star and the largest object in the solar system, whose estimated age is 4.5 billion years. It is about 150 million-km from Earth, and is the source of energy for the entire solar system. Without solar energy, life on Earth, as we know, can not exist. The gravity of the sun holds all the objects of the solar system together.

Aditya L1 ISRO’s first Sun mission LIVE: What is Lagrange point 1?
According to ISRO officials, the spacecraft will be placed in a halo orbit around Lagrange point 1 (L1) of the Sun-Earth system, about 1.5 million km from the Earth. The L1 point is about one per cent of the total distance between the Earth and the Sun.
Aditya L1 ISRO’s first Sun mission LIVE: Major Objectives
The suits of Aditya L1 payloads are expected to provide the “most crucial information” to understand the problem of coronal heating, coronal mass ejection, pre-flare and flare activities and their characteristics, dynamics of space weather, and propagation of particles and fields, officials said.
The major science objectives of the Aditya-L1 mission are:
– Study of the Solar upper atmospheric (chromosphere and corona) dynamics.
– Study of chromospheric and coronal heating, physics of the partially ionized plasma, initiation of the coronal mass ejections, and flares.
– Observe the in-situ particle and plasma environment, providing data for the study of particle dynamics from the Sun.
– Physics of the solar corona and its heating mechanism.
– Diagnostics of the coronal and coronal loops plasma: Temperature, velocity and density.
– Development, dynamics and origin of coronal mass ejections (CMEs).
– Identify the sequence of processes that occur at multiple layers (chromosphere, base and extended corona) which eventually leads to solar eruptive events.
– Magnetic field topology and magnetic field measurements in the solar corona.
– Drivers for space weather (origin, composition and dynamics of solar wind).
Aditya L1 ISRO’s first Sun mission LIVE: What will happen during the final orbit manoeuvre?
A maneuver that would last only a few seconds will see a 180-degree flip of the spacecraft Aditya L1. This brings the thrusters to the front to slow down the spacecraft while aiming for a different orbit.
Aditya L1’s liquid apogee motors are currently in a hibernated state due to the cold space environment, since its last firing that was a couple of months ago.
When ISRO will commanded the motors, they will instantly fire for the specific duration and perform the manoeuvre precisely at that particular moment. However, this execution requires precision to avoid overdoing, underdoing or mistiming the motor firing.
Aditya L1 ISRO’s first Sun mission LIVE: What if the spacecraft misses halo orbit?
If the spacecraft fails to perform the manoeuvre in case of overfiring or underfiring of the engine and misses the sweet spot in the expected orbit range then there would be trouble. The spacecraft may miss the gravity capture by the L1 point and enter a higher orbit throwing it off the desired orbit. This would lead to higher fuel consumption which is very crucial for longer mission life.

Aditya L1 ISRO’s first Sun mission LIVE: Satellite to be placed in Halo Orbit. What this means?
According to ISRO, the Aditya L1 satellite will be placed in a halo orbit around Lagrange point 1 (L1) of the Sun-Earth system, about 1.5 million km from the Earth.
The L1 point is about one per cent of the total distance between the Earth and the Sun.
A satellite in a halo orbit around the L1 point has the major advantage of continuously viewing the Sun without any occultations/eclipses, they said, adding, this will provide a greater advantage in observing solar activities and its effect on space weather in real time.
