Aditya-L1: PSLV-C57, the Polar Satellite Launch Vehicle's 59th flight, was successful in launching Aditya-L1 into low-Earth orbit. The Indian Space Research Organisation (ISRO) declared during a livestream of the launch event that the Aditya-L1 mission is now complete. India's first observatory in orbit, Aditya-L1, is used to study the Sun. Aditya-L1 was launched by ISRO on September 2, 2023, at 11:50 IST aboard a PSLV-XL rocket. The journey to Aditya-L1's final position, a halo around Lagrange point 1 (L1), will take about 125 days.

Aditya-L1 has been launched into low-Earth orbit, and during the following few days, the spacecraft will perform orbit-raising maneuvers. Aditya-L1's orbit will become increasingly elliptical with each orbit-raising maneuver.

Aditya-L1 will leave the gravitational pull of Earth after completing three orbit-raising maneuvers and enter the cruise phase. Aditya-L1 will be pointed in the direction of the halo orbit insertion by this stage.

Aditya-L1 will hover in the orbit after being launched into the halo orbit around L1 and use little fuel. This is so that the centripetal force it produces will be equivalent to the gravitational pull of the Sun and the Earth. This is how Lagrange points are unique. The Aditya-L1 will be able to observe the Sun for five years without interruption thanks to L1, which is another benefit.

Aditya-L1 will investigate the solar corona, the processes that occur there, the issue of coronal mass ejections, the dynamics of solar flares, and how solar activity affects the weather in space.

The observatory has seven payloads, four of which are for remote sensing and three of which are for in-situ observations.

The payloads for remote sensing will act as spectrometers. Particle analyzers make up two of the in-situ payloads, while a magnetometer is the third.

Aditya-L1 will simultaneously observe the Sun in visible, X-ray, and ultraviolet light. The spacecraft will research the Sun's high-energy particle emissions.

1.5 million kilometers from Earth and 148.5 million kilometers from the Sun will separate the observatory from those bodies of matter.
