Aditya-L1 has started

On September 2, 2023, at 9:20 Moscow time, a PSLV-C57 carrier rocket with the first Indian satellite for studying the Sun, Aditya-L1, was launched from the Satish Dhawan cosmodrome in southeastern India. After launching into low Earth orbit, the spacecraft will conduct a series of maneuvers to gain the speed necessary to reach the L1 Lagrange point of the Earth-Sun system.

The flight to the final destination will take about four months. At point L1, located at a distance of 1.5 million kilometers from Earth, the satellite will enter a halo orbit around the balance of forces of the Sun and the Earth. This advantageous position will allow Aditya-L1 to continuously observe the Sun and register solar radiation and magnetic storms in advance.

A stable position at the L1 point minimizes the need for orbit correction, optimizing mission efficiency. Seven Indian scientific instruments are installed on board the satellite, including a coronograph, an ultraviolet telescope, X-ray spectrometers and magnetometers.

Four devices are designed for remote sensing of the Sun, continuously monitoring its activity. Three more instruments will carry out direct measurements of the solar wind, plasma and magnetic field.

Thanks to such a complex of equipment, the Aditya-L1 mission promised to significantly expand our knowledge about the behavior of the Sun and its interaction with the Earth and near-Earth outer space. The successful launch of India's first solar probe marks an important milestone in the exploration of our nearest star and opens a new chapter in India's exploration of space.
