Mission Timeline

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.

Launch

PSLV-C57 lifts off from Sriharikota at 11:50 IST, placing Aditya-L1 into an elliptical Earth parking orbit.

Sep 2023

Earth-bound manoeuvres

A series of orbit-raising burns progressively stretches the orbit, building the energy needed to escape Earth's gravity.

Trans-Lagrangian injection

The spacecraft breaks free of Earth orbit and begins its cruise toward the L1 point.

Sep 2023 – Jan 2024

The cruise to L1

Aditya-L1 coasts about 1.5 million km toward the Sun–Earth L1 point, with a mid-course trajectory correction on the way.

Halo Orbit Insertion 🎉

126 days after launch, a precise burn captures Aditya-L1 into its halo orbit around L1 — its permanent science home.

Magnetometer boom deployed

The 6-metre boom carrying the magnetometer sensors unfurls, completing the observatory's instrument suite.

2 Jul 2024

First halo orbit completed

Aditya-L1 finishes its first full loop around L1 — about 178 days — after routine station-keeping manoeuvres.
