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.
