Aditya-L1: PM Modi congratulates ISRO for successful launch of India’s first solar mission

Prime Minister Narendra Modi on Saturday congratulated The Indian Space Research Organisation (ISRO) on the successful launch of India’s first solar mission Aditya-L1 from Satish Dhawan Space Centre in Sriharikota."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," PM Modi tweeted.The PSLV-C57.1 rocket carrying the Aditya-L1 orbiter, lifted off successfully from the Satish Dhawan Space Centre in Sriharikota, Andhra Pradesh at 11.50 am on Saturday.The successful launch of the maiden solar mission of the Indian Space Research Organisation (ISRO) came on the heels of the historic lunar landing mission — Chandrayaan-3.ISRO successfully placed a lander on the unexplored lunar South Pole, a feat that put India in the record books as the first country to do so.The Aditya-L1 mission is expected to reach the observation point in four months. It will be placed in a halo orbit around Lagrangian Point 1 (or L1), which is 1.5 million km away from the Earth in the direction of the sun.It will carry seven different payloads to have a detailed study of the sun, four of which will observe the light from the sun and the other three will measure in-situ parameters of the plasma and magnetic fields.The largest and technically most challenging payload on Aditya-L1 is the Visible Emission Line Coronagraph or VELC.VELC was integrated, tested, and calibrated at the Indian Institute of Astrophysics’ CREST (Centre for Research and Education in Science Technology) campus in Hosakote in collaboration with ISRO.This strategic location will enable Aditya-L1 to continuously observe the sun without being hindered by eclipses or occultation, allowing scientists to study solar activities and their impact on space weather in real time. Also, the spacecraft's data will help identify the sequence of processes that lead to solar eruptive events and contribute to a deeper understanding of space weather drivers.Major objectives of India’s solar mission include the study of the physics of solar corona and its heating mechanism, the solar wind acceleration, coupling and dynamics of the solar atmosphere, solar wind distribution and temperature anisotropy, and origin of Coronal Mass Ejections (CME) and flares and near-earth space weather.With inputs from agencies
