Third orbit of Aditya-L1 successfully completed: ISRO

Aditya L1 instruments to understand the heating of the Sun’s corona and solar wind, solar earthquakes or ‘coronal mass ejections’ (CMEs), near-Earth space weather, space weather dynamics and its propagation. will be used. Particles and fields etc. The most important data is likely to be found.

Bengaluru. India’s first mission to the Sun, the Aditya-L1 spacecraft to study the Sun’s outer atmosphere, successfully completed its third Earth orbit early Sunday. The Indian Space Research Organization (ISRO) reported this. The space agency’s Bengaluru-based ‘Telemetry, Tracking and Command Network’ (ISTRAC) successfully carried out the mission, ISRO said.

ISRO wrote on social media platform X, The third operation related to Earth Orbit (EBN-3) was successfully completed from ISTRAC, Bengaluru. ISTRAC/ISRO centers Mauritius, Bengaluru, SDSC (Satish Dhawan Space Centre) – SHAR and Port Blair monitored the satellite during the mission. The new orbit achieved is 296 km x 71,767 km, the space agency said.

He said that the fourth Earth orbit procedure of ‘Aditya L1’ is scheduled on September 15, 2023 at around 2 PM IST. ‘Aditya L-1’ is India’s first space observatory, which will study the Sun’s outer atmosphere by staying at the first Sun-Earth Lagrangian point (L-1), about 1.5 million km from Earth. ISRO’s Polar Satellite Launch Vehicle (PSLV-C57) successfully launched ‘Aditya L1’ from the second launch pad of the Satish Dhawan Space Center (SDSC) at Sriharikota, Andhra Pradesh on September 2.

The first and second orbital maneuvers of ‘Aditya L1’ were successfully carried out on September 3 and September 5 respectively. ‘Aditya L1’ will undergo one more orbital process before entering the transition orbit towards the Lagrange point L-1. This process needs to be done during Aditya L1’s 16-day journey around Earth, when the spacecraft will have gained the necessary momentum for its onward journey to L1. ISRO had said shortly after the launch that ‘Aditya L1’ is likely to reach the desired orbit at the L1 point after about 127 days.

The space agency said the orbiter in a coronal orbit around the L1 point has the advantage of continuously observing the Sun without interruption or eclipsing. This makes it possible to monitor solar activity and their effects on space weather in real time. ‘Aditya L1’ carries seven scientific instruments developed by ISRO and other national research laboratories including the Indian Institute of Astrophysics, Bengaluru and the ‘Inter-University Center for Astronomy and Astrophysics, Pune’. These instruments will use electromagnetic, particle and magnetic field detectors to study the photosphere, chromosphere and outermost layers of the Sun, the corona.

Four instruments on board ‘Aditya L1’ will observe the Sun directly using the special location L1, while the remaining three instruments will study the particles and fields on L1 ‘in-situ’, thereby studying the solar system in the interstellar medium. Will study dynamics. Significant data is expected to be obtained on the effects of Aditya L1 instruments to understand the Sun’s corona and solar wind heating, solar earthquakes or ‘coronal mass ejections’ (CMEs), near-Earth space weather, space weather dynamics and particle dispersion. will be used. and fields etc. The most important data is likely to be found.

According to scientists, there are five ‘Lagerian’ points (or parking zones) between the Earth and the Sun, when an object reaches it and stops there. Lagrangian points are named after the Italian-French mathematician Joseph-Louis Lagrange. A spacecraft can use these points to stay in space longer with less fuel consumption. The gravitational force between the Sun and Earth is balanced at the Lagrangian point, making it easy to stop the satellite at that point.
