The article collection "Aditya-L1: A Space Based Observatory to Study the Solar Atmosphere, Solar Wind, Heliosphere, and Space Weather" has been completed and is now published in the journal Solar Physics. All articles are free to read from 14 November to 14 December 2025.
Aditya-L1 is India’s first dedicated observatory-class solar mission, which was launched from the Indian space port of Sriharikota on 2 September 2023. The satellite was placed in the halo orbit around the first Lagrange point of the Sun-Earth system on 6 January 2024 and completed the first orbit on 2 July 2024. Aditya-L1 is configured with seven payloads, four of which are remote sensing and three in situ payloads.
This topical collection consists of a group of ten articles that detail the science objectives of each instrument on board Aditya-L1 mission and their configuration. The articles also cover the laboratory calibration and initial on board observations, providing a glimpse of potential observables from the Aditya-L1 mission.
