India's first space-based solar observatory — watching the Sun without pause from the Sun–Earth Lagrange point L1, 1.5 million kilometres from home.
The hands-on side of the mission — fly a spacecraft to L1, check the Sun right now, play games, and test yourself.
Fly a spacecraft from Earth all the way to a halo orbit at L1 in an interactive simulator.
Live space-weather readings and the newest images of the Sun, updated from NOAA & NASA SDO.
Cool Sun facts, a memory game, a “your weight on the Sun” calculator and a Junior Explorer certificate.
Quizzes on Aditya-L1 and the Sun — how many can you get right?
Solar imagery, mission scenes and official ISRO videos.
The latest Aditya-L1 and solar-science headlines, refreshed automatically.
On 2 September 2023, ISRO launched India's first dedicated mission to study the Sun — and on 6 January 2024 it settled into orbit around L1, a gravitational sweet spot with an unbroken view of our star.
The country's first spacecraft built entirely to study the Sun — its atmosphere, its wind, and its storms.
From 1.5 million km away it watches the Sun continuously, with no eclipses, and sees space weather before it reaches Earth.
Four remote-sensing payloads and three in-situ payloads study the Sun across visible, ultraviolet and X-ray light — and sample the solar wind directly.
