Aditya-L1
Aditya-L1 — India's first space mission dedicated to the Sun (ISRO), launched on 2 September 2023 and placed in a halo orbit around the Sun–Earth L1 point on 6 January 2024. Its seven instruments watch the Sun's corona, chromosphere and photosphere, its flares and coronal mass ejections, and sample the solar wind.

Mission
Aditya-L1 is India's first space mission dedicated to the Sun. ISRO launched it on a PSLV rocket from Sriharikota at 06:20 UTC on 2 September 2023; after five manoeuvres around Earth it set out for the Sun–Earth L1 point, and on 6 January 2024 it was placed in a halo orbit around it, about 1.5 million km from Earth, with a period of about 178 days. From there it has an unbroken view of the Sun. It carries seven instruments: four look at the Sun — a coronagraph for the corona, an ultraviolet telescope and two X-ray spectrometers for flares — and three sample the solar wind, its particles and the magnetic field around the spacecraft. Its science goals include what heats the Sun's corona, what accelerates the solar wind and what produces coronal mass ejections.
