ISRO’s solar mission, Aditya-L1, undergoes its third successful orbit raising maneuver

The Aditya-L1 spacecraft will observe the Sun from the Lagrange 1 or L-1 point

New Delhi:

The Aditya-L1 spacecraft has undergone a third successful Earth orbit raising maneuver, the Indian Space Research Organization (ISRO) said today.

The orbit raising maneuver was directed from ISRO’s Telemetry, Tracking and Command (ISTRAC) network in Bengaluru and the space agency’s ground stations in Mauritius and Bengaluru, and Port Blair tracked the satellite during the crucial process of taking India’s first solar mission one step closer to the satellite. Her destination.

After the successful maneuver, the satellite’s new orbit reached 296 km x 71,767 km. The next maneuver is scheduled to take place on September 15 around 2 am, ISRO said.

ISRO’s ambitious mission to study the Sun was successfully launched on September 2 from the Satish Dhawan Space Center in Sriharikota, Andhra Pradesh.

The spacecraft has already completed two orbital maneuvers around the Earth and will perform one more before being placed in a transfer orbit towards the L1 Lagrange point. The spacecraft is expected to reach the intended orbit at point L1 after 125 days. Earlier, the Aditya-L1 satellite shared stunning images of the Earth and the Moon.

The Aditya-L1 spacecraft will observe the Sun from the Lagrange 1 or L-1 point, which is 1.5 million kilometers from Earth. According to ISRO, the spacecraft placed in the halo orbit around the L1 point has the advantage of seeing the Sun continuously without any occultation or eclipse. This will provide greater advantage for monitoring solar activities and their impact on space weather in real time.

The main objectives of the mission are – to study the physics of the solar corona and its heating mechanism, the acceleration of the solar wind, the coupling and dynamics of the solar atmosphere, the distribution of the solar wind and its temperature variation, and the origin of coronal mass ejections (CME). Flares and space weather near Earth.

The successful launch of the Aditya-L1 spacecraft, on board a PSLV rocket, added another feather to ISRO’s title as one of the world’s leading space agencies. Nearly two weeks before the launch of the Sun mission, ISRO’s Chandrayaan 3 spacecraft touched down near the moon’s south polar region, making India the first country to successfully soft-land in that region and the fourth on the moon’s surface.
