India's Aditya-L1 spacecraft healthy, on its way to the Sun-Earth L1 point: ISRO

The Indian Space Research Organisation (ISRO) on Sunday said that the Aditya-L1 mission's spacecraft is healthy and on its way to Sun-Earth Lagrange Point 1 (L1).

In a post on X (formerly Twitter), the space agency wrote, "The Spacecraft is healthy and on its way to Sun-Earth L1. A Trajectory Correction Maneuvre (TCM), originally provisioned, was performed on October 6, 2023, for about 16 s. It was needed to correct the trajectory evaluated after tracking the Trans-Lagrangean Point 1 Insertion (TL1I) maneuvre performed on September 19, 2023. TCM ensures that the spacecraft is on its intended path towards the Halo orbit insertion around L1."

"As Aditya-L1 continues to move ahead, the magnetometer will be turned on again within a few days," it further stated.



On September 30, the spacecraft had travelled beyond a distance of 9.2 lakh km from Earth, successfully escaping the sphere of Earth's influence.

"This is the second time in succession that ISRO could send a spacecraft outside the sphere of influence of the Earth, the first time being the Mars Orbiter Mission," it had previously stated.

The ISRO had also said that the Aditya-L1 solar mission spacecraft has commenced collecting data which will help scientists analyse the behaviour of particles surrounding Earth in September.

Data collected around L1 would provide insights into the origin, acceleration, and anisotropy of solar wind and space weather phenomena, it said.

The launch of Aditya-L1 by PSLV-C57 rocket was successfully accomplished by ISRO on September 2.

Aditya-L1 spacecraft carries a total seven different payloads to study the Sun, four of which will observe the light from the Sun and the remaining three will measure in-situ parameters of the plasma and magnetic fields.

Aditya-L1 will be placed in a halo orbit around the Lagrangian Point 1 (L1), which is 1.5 million km from the Earth in the direction of the Sun. It will revolve around the Sun with the same relative position and hence can see the Sun continuously.
