ISRO`s Aditya-L1 Completes First Halo Orbit, Key Moments In Pics
The Indian Space Research Organisation (ISRO) announced that India’s first space-based solar observatory, Aditya-L1 completed its first halo orbit around the Sun-Earth L1 point. The research department said that the Aditya-L1 spacecraft in the Halo orbit takes 178 days to complete a revolution around the L1 point. The solar mission was launched on September 2, 2023, and inserted into its targeted halo orbit on Jan 6, 2024.
Aditya-L1's instruments are designed to primarily study the solar atmosphere, focusing on the chromosphere and corona. In addition, in-situ instruments will monitor the local environment at the L1 point. There are a total of seven payloads on-board with four of them carrying out remote sensing of the Sun and three of them carrying in-situ observation. (Image: ISRO)
Aditya L1 is the first space-based Indian mission to study the Sun. The solar mission is placed in a halo orbit around the Lagrange point 1 of the Sun-Earth system, which is approx 1.5 million km from the Earth. (Image: ISRO)
India's Adittya L-1 spacecraft carries seven payloads to detect the photosphere, chromosphere and the outermost layers of the Sun with the use of electromagnetic particle and magnetic field detectors.

A satellite placed in the halo orbit around the L1 point has the major advantage of continuously viewing the Sun without any occultation/eclipses. This solar mission was initiated on September 2, 2023. (Image: ISRO)
