Aditya-L1's halo orbit entry in Jan; vital Ganganyaan test on Oct 21: ISRO chief

15 Oct 2023

Aditya-L1 will be placed in a halo orbit around Lagrangian Point 1 (or L1), which is 1.5 million km away from the Earth in the direction of the sun.
Indian Space and Research Organisation (ISRO) chief S Somanath on Sunday said that India's maiden space-based solar mission, the Aditya-L1 spacecraft, is progressing smoothly and is scheduled to reach Lagrange Point 1 (L1) by mid-January.
Speaking to reporters in Madurai, Tamil Nadu, Somnath explained, β€œIt is working very well. Currently, it takes almost 110 days to travel from Earth to the L1 point. So by the middle of January, it will reach the L1 point. Then at that point, we will do the insertion into the Lagrange Point. That is called the halo orbit. It's a big orbit. So that will happen by the middle of January.”
Aditya-L1 was launched from the Satish Dhawan Space Centre in Sriharikota on September 2, days after the Chandrayaan-3 mission made a soft landing on the Moon's south pole. It carried seven different payloads to have a detailed study of the sun, four of which will observe the light from the sun and the other three will measure in-situ parameters of the plasma and magnetic fields. These instruments were intended to provide data on solar activities, such as solar flares and coronal mass ejections.
