Scroll down to follow Aditya-L1's journey — from an Earth parking orbit to a halo orbit 1.5 million km away. Each milestone fades in as you reach it.
PSLV-C57 lifts off from Sriharikota at 11:50 IST, placing Aditya-L1 into an elliptical Earth parking orbit.
A series of orbit-raising burns progressively stretches the orbit, building the energy needed to escape Earth's gravity.
The spacecraft breaks free of Earth orbit and begins its cruise toward the L1 point.
Aditya-L1 coasts about 1.5 million km toward the Sun–Earth L1 point, with a mid-course trajectory correction on the way.
126 days after launch, a precise burn captures Aditya-L1 into its halo orbit around L1 — its permanent science home.
The 6-metre boom carrying the magnetometer sensors unfurls, completing the observatory's instrument suite.
Aditya-L1 finishes its first full loop around L1 — about 178 days — after routine station-keeping manoeuvres.
On the mission's first anniversary, ISRO releases Aditya-L1 science data to the global research community, with further releases following.
ISRO announces that Aditya-L1's particle and field measurements, combined with a global ground magnetometer network, explain unusual “dawn-side” geomagnetic disturbances recorded during the two most intense storms of Solar Cycle 25 — on 10 May and 10 October 2024.
ISRO reports that SoLEXS detected “iron fluorescence” — a characteristic X-ray glow at 6.40 keV — across 47 X-class flares in 2024, giving a new way to gauge the height of a flare's X-ray source above the Sun's surface. Published in Solar Physics.
The government tells the Rajya Sabha that Aditya-L1 has captured the first spectroscopic signatures of a coronal mass ejection's onset (VELC), alongside its flare and space-weather results — a progress report on nearly two years of continuous science operations at L1.
ISRO highlights a peer-reviewed study combining SUIT, SoLEXS and HEL1OS observations. Small, short-lived brightenings appeared hours before major flares and clustered near the eventual flare site, offering new clues to how eruptions build and how they might one day be forecast.
Two payload studies report journal acceptance: a joint VELC–Proba-3 analysis presents the first coordinated CME observations by the two coronagraphs, while a HEL1OS paper documents the hard-X-ray instrument's operations, automated data pipeline and science-ready flare products.
An accepted Astrophysical Journal survey finds quasi-periodic hard-X-ray pulsations in about three quarters of 34 X-class flares observed by HEL1OS. A separate Astrophysical Journal Letters study uses VELC spectroscopy and SDO imaging to reconstruct the nonuniform lateral expansion of an August 2024 CME.
