NEW DELHI: India’s first photo voltaic mission, Aditya-L1 was successfully launched from Satish Dhawan Area Centre in Sriharikota, Andhra Pradesh, at eleven.50am on Saturday.
After the profitable launch, Prime Minister Narendra Modi congratulated the Isro scientists and engineers for his or her tireless effort.
“After the success of Chandrayaan-3, India continues its area journey.Congratulations to our scientists and engineers at @isro for the profitable launch of India’s first Photo voltaic Mission, Aditya -L1.
Our tireless scientific efforts will continue so as to develop higher understanding of the Universe for the welfare of complete humanity,” PM Modi stated on X, previously often known as Twitter.
In an handle after the launch, Isro chairman Dr. S Somanath stated that the car has positioned the satellite tv for pc precisely into its meant orbit.
In the meantime, Isro in a tweet stated added that India’s first photo voltaic observatory has begun its journey to the vacation spot of Sun-Earth L1 level.
Listed here are the important thing highlights of the photo voltaic mission:
Mission aimed toward learning solar activity
India’s photo voltaic mission comes close on the heels of its successful lunar endeavour — Chandrayaan-three. With Aditya-L1, Isro will venture into the research of solar activities and its effect on area climate.
Aditya L1 is designed for offering distant observations of the photo voltaic corona and conduct in-situ observations of the solar wind at L1 (Sun-Earth Lagrangian level), which is about 1.5 million kilometres from the Earth.
Goal of the mission
The scientific goals of Aditya-L1 embrace the research of coronal heating, photo voltaic wind acceleration, coronal mass ejections (CMEs), dynamics of solar environment and temperature anisotropy.
In accordance with ISRO, there are five Lagrangian factors between the Sun and the Earth, and the L1 level within the Halo orbit would offer a larger benefit of constantly viewing the Sun with none prevalence of eclipse.
On embarking on such a posh mission, ISRO stated the Sun is the nearest star and subsequently may be studied in rather more detail as compared to the others.
By learning the Solar far more about could possibly be learnt about stars in the Milky Method in addition to in numerous different galaxies, ISRO stated.
Aditya-L1 mission launch reside updates
What is Aditya-L1
Aditya-L1 is a satellite devoted to the great research of the Solar. It has seven distinct payloads — five by Isro and two by educational establishments in collaboration with Isro — developed indigenously.
Following its scheduled launch, Aditya-L1 will stay in Earth-sure orbits for 16 days, during which it’s going to bear five manoeuvres to realize the required velocity for its journey.
To realize this, the spacecraft is full of seven scientific equipment: The 2 important payloads are Seen Emission Line Coronagraph (VELC) for Corona imaging & spectroscopy studies and Solar Ultraviolet Imaging Telescope (SUIT) for Photosphere and Chromosphere imaging (slender & broadband).

ISRO all set for Aditya-L1 launch from Satish Dhawan Area Centre in Sriharikota
Launch timing
The Sun observatory was fired from the second launch pad at this spaceport at 11.50 am right now. ISRO Chairman S Somanath stated the Sun mission will take one hundred twenty five days to succeed in the precise radius.
The spacecraft’s trajectory
Initially, the Aditya-L1 spacecraft can be positioned in a low earth orbit. It will be made more elliptical and later the spacecraft shall be launched in the direction of the Lagrange point L1 through the use of on-board propulsion methods.
As the spacecraft travels in the direction of L1, it’s going to exit the Earth’s gravitational Sphere of Influence. After exit, the cruise part will start and subsequently, the spacecraft can be injected into a large halo orbit round L1. It might take almost 4 months to succeed in the meant L1 point.
The Aditya-L1 payloads are anticipated to offer probably the most crucial info to know the problems of coronal heating, Coronal mass ejection (CME), pre-flare, and flare actions, and their characteristics, dynamics, and area climate.
The primary payload of Aditya-L1 the Seen Emission Line Coronagraph can be sending 1,440 photographs per day to the ground station for evaluation on reaching the meant orbit.
Payload to ship 1,440 photographs per day
The Visible Emission Line Coronagraph (VELC), the primary payload of Aditya L1 will probably be sending 1,440 photographs per day to the bottom station for evaluation on reaching the meant orbit.
“From the continuum channel, which is the imaging channel, a picture will approach — one image per minute. So roughly 1,440 photographs for twenty-four hours, we can be receiving on the ground station,” Aditya L1 Challenge Scientist and Operation Manager for VELC Dr Muthu Priyal stated.
She stated, IIA will host the VELC Payload Operations Centre (POC), which can receive uncooked knowledge from ISRO’s Indian Area Science Knowledge Centre (ISSDC), process them further to make it appropriate for scientific analysis, and ship it again to ISSDC for dissemination.
In response to IIA officials, one hundred ninety kg VELC payload will send pictures for 5 years, which is the nominal life of the satellite tv for pc, nevertheless it might final long relying on the gasoline consumption, and so on.
First pictures to be out there by February-finish
“The satellite is predicted to be put into orbit in the midst of January and then we’ll do the check if all of the techniques are working properly and by the top of February we anticipate to get the regular knowledge. It’s going to take time and we’ve to check instrument by instrument. First we’ll check the smaller equipment, and the VELC’s shutter will probably be opened final, by mid of February,” Prof Jagdev Singh stated.
‘Research of photo voltaic quakes should as they affect geomagnetic subject’
A prime scientist stated the monitoring of the Solar on a 24-hour basis is a should to review photo voltaic quakes which may alter the geomagnetic fields of earth.
Explaining the necessity to research the Sun, Professor and In-Charge Scientist at the Indian Institute of Astrophysics (IIA), Dr R Ramesh informed PTI that simply as there are earthquakes on Earth, there are something referred to as photo voltaic quakes – referred to as as Coronal Mass Ejections (CMEs) – on the floor of the Solar.
In this process, tens of millions and hundreds of thousands of tons of photo voltaic materials are thrown into the interplanetary area, he stated, including these CMEs can journey at a velocity of approximately 3,000 km per second.
