Aditya-L1 Launch Highlights: PSLV-C57 accomplishes mission! Satellite sucessfully injected in intended orbit

Prime Minister Narendra Modi took to X, and tweeted, " After the success of Chandrayaan-3, India continues its space journey. Congratulations to our scientists and engineers at ISRO for the successful launch of India’s first Solar Mission, Aditya -L1. Our tireless scientific efforts will continue in order to develop better understanding of the Universe for the welfare of entire humanity."

Union Home Minister Amit Shah congratulates scientists of ISRO for the successful launch of Aditya L-1. "The nation is proud and delighted over the successful launch of Aditya L1, India's first solar mission. It is a giant stride towards fulfilling PM Modi's vision of an Atmanirbhar Bharat in the space sector, during the Amrit Kaal." tweets Amit Shah

"We extend our congratulations to ISRO on the successful launch of the Aditya L1 mission. This achievement follows the Chandrayaan-3 mission, marking another significant milestone for India's space sector. It not only reaffirms India's capabilities in space exploration but will establish trust in our private sector's ability to collaborate internationally and contribute to the global space industry. These successes will also further enhance funding prospects for our private space companies," Lt. Gen. AK Bhatt (Retd.), Director General, Indian Space Association (ISpA) said.

Following its launch from the Satish Dhawan Space Centre, the mission team will first position the spacecraft into a Low Earth Orbit. Subsequently, the orbit will be adjusted to become more elliptical in shape. The spacecraft will then undergo a crucial maneuver where its on-board propulsion system will be employed to propel it towards the Lagrange L1 point, allowing it to escape Earth's gravitational Sphere of Influence and progress towards L1. Eventually, it will be directed into a broad Halo Orbit encircling the L1 point in close proximity to the Sun.

ISRO has indicated that the entire journey from launch to reaching the L1 point is expected to span approximately four months for the Aditya-L1 Mission.

ISRO has announced that the vehicle's performance is normal as of now. The suits of Aditya L1 payloads are expected to provide most crucial informations to understand the problem of coronal heating, coronal mass ejection, pre-flare and flare activities and their characteristics, dynamics of space weather, propagation of particle and fields etc.

This is the longest PSLV mission ever taken. The sepaartion will take 63 minutes 19 seconds. As of now, The lift coincides with the ignition of core S139 solid rocket motor and ignition of the four ground lit strap ons, as per ISRO

Dr. Anil Bharadwaj, Director, Physical Research Laboratory told ANI, "We are all very excited about the launch. This is a very unique mission from India to study the Sun...It will take maybe a month or so to commission all the experiments that are there on the Aditya L1. After that, we will be able to continuously start looking into the Sun..."

"The last mission that went to L1 point was five years before Aditya L1. This would be the first mission of the new generation. The mission will observe the Sun simultaneously in optical, UV and X-ray," Mayank N. Vahia, Retired professor from Tata Institute of Fundamental Research, told ANI.

In the long run, information gathered from the mission holds the potential to enhance our comprehension of the Sun's influence on Earth's climate patterns and the origins of solar wind—a continuous flow of particles emitted by the Sun that traverses through our solar system. These insights have been articulated by scientists affiliated with the Indian Space Research Organisation (ISRO).
