Aditya-L1 took a bit over 4 months to reach its final orbit around the Sun–Earth L1 point, and it is planned to operate there for several years.

How long did Aditya-L1 take to reach L1?

  • Launched: 2 September 2023 by ISRO’s PSLV rocket.
  • Phase 1 – Earth orbits: It spent about 2 weeks in Earth-bound orbits, performing several maneuvers to build up the right velocity.
  • Phase 2 – Cruise to L1: After a trans-L1 maneuver, the cruise to the L1 region took roughly 110–120 days.

Putting those together, the spacecraft reached its halo orbit around the L1 point on 6 January 2024, which is about 126 days (just over 4 months) after launch.

In simple terms: from liftoff to “settled” at L1 took a bit more than four months.

How long will Aditya-L1 operate?

  • Planned mission duration is around 5 years in its halo orbit around the L1 point.
  • In that orbit, it takes about 178 days to complete one loop around L1, so it will circle that region many times over its lifetime.

This long stay lets Aditya-L1 continuously monitor the Sun’s activity and space weather with minimal interruption.

TL;DR:

  • Time to reach operational orbit at L1: about 4 months after launch (126 days).
  • Planned mission life at L1: roughly 5 years of solar observations.
