Finance Minister Reviews National Large Solar Telescope Site Near Pangong Lake, Ladakh
Samaya Jyothi News | Ladakh, India — In a significant step toward advancing India’s astronomical research capabilities, Union Finance Minister Smt. Nirmala Sitharaman visited the proposed site of the National Large Solar Telescope (NLST) project, located near the iconic Pangong Lake in Merak, Ladakh. Perched at an impressive altitude of approximately 4200 meters, this site is poised to become a global center for cutting-edge solar observations.
Joining her on this scientific visit was Dr. Annapurni Subramaniam, Director of the Indian Institute of Astrophysics (IIA), the lead institution behind the NLST initiative. The project site promises long durations of high-transparency skies — an essential feature for solar coronagraphy and other advanced observational needs in the optical and near-infrared (IR) spectra.
The NLST is envisioned as a ground-based 2-meter class optical and near-IR telescope, specifically designed for studying the sun’s corona and magnetic field activity. This ambitious project not only underscores India’s growing expertise in solar physics but also highlights the government’s commitment to expanding the nation’s footprint in space science and technology.

Why Ladakh? A Strategic Choice for Solar Observation
The location in Merak, situated along the banks of the crystal-clear Pangong Lake, was selected after extensive atmospheric studies conducted over several years. With minimal atmospheric pollution and clear skies for a significant portion of the year, this high-altitude desert offers ideal conditions for coronagraphic studies and uninterrupted solar tracking.
“NLST will allow India to observe the sun in a way few nations can. This site near Pangong is a national treasure for solar research,” remarked Dr. Subramaniam during the visit.
NLST aims to enable real-time solar monitoring and contribute data critical for understanding solar storms, sunspot activity, and coronal mass ejections. These phenomena have far-reaching impacts — from disrupting satellite communications to affecting electrical grids on Earth.
A Boost for Scientific Infrastructure
Finance Minister Sitharaman’s visit underscores the central government’s focus on strengthening India’s scientific and technological infrastructure. During her review, she expressed strong support for the timely execution of the NLST, recognizing its potential to place India among the top nations in solar research capabilities.
“The National Large Solar Telescope will enhance India’s stature in global space science. We are committed to supporting such visionary projects that benefit science and humanity,” Sitharaman stated during the interaction with IIA officials and local authorities.
Her presence also signals the importance of cross-ministerial collaboration, where scientific research, infrastructure development, and strategic location planning come together in harmony.
Empowering Local Communities
Beyond its scientific value, the NLST project is expected to generate socio-economic benefits for the local population in Ladakh. The development of the observatory will involve skill development, infrastructure creation, and the growth of eco-scientific tourism, creating employment opportunities for the surrounding communities.
Efforts are underway to ensure that the construction and operation of the observatory maintain environmental sustainability, respecting Ladakh’s delicate ecosystem and unique cultural heritage.
Looking to the Sky, Leading the Future
With the successful implementation of the NLST, India will join an elite league of nations capable of deep, high-resolution solar study from terrestrial bases. The data collected will be shared with global scientific communities, fostering international cooperation and research partnerships.
This project also complements India’s growing space exploration agenda, in line with missions such as Aditya-L1, ISRO’s solar observation satellite currently en route to study the sun from space.
As the sun set over the snowy ridges of Ladakh, the visit by Finance Minister Sitharaman marked more than a formal inspection—it represented India’s aspiration to look beyond Earth, decode the universe, and lead in the frontiers of scientific exploration.
