India’s first solar mission spacecraft, Aditya-L1, completed its first halo orbit around the Sun-Earth L1 point on Tuesday. International Broadcasting Organization saying.
The space agency said its station-keeping maneuver on Tuesday ensured its smooth transition to the second halo orbit.
The Aditya-L1 mission, which is an Indian solar observatory at the L1 Lagrangian point, was launched on 2 September 2023 and inserted into its planned halo orbit on 6 January 2024.
According to ISRO, the Aditya-L1 spacecraft in the halo orbit takes 178 days to complete one revolution around the L1 point.
During its journey in the halo orbit, the Aditya-L1 spacecraft will be subject to several perturbing forces that will push it away from its intended orbit, the space agency said.
“Aditya-L1 performed two station-keeping manoeuvres on February 22 and June 7 respectively to maintain this orbit. The third station-keeping manoeuvre performed today has enabled its journey to continue on the second halo orbital path around L1,” ISRO said.
The agency explained that Aditya L1’s journey around the Sun-Earth L1 Lagrangian point involves modeling complex dynamics.
Understanding the various perturbing forces acting on the spacecraft helped determine the trajectory accurately and plan precise orbital maneuvers, he added.
“With today’s maneuver, the state-of-the-art flight dynamics software developed in-house at URSC-ISRO for the Aditya-L1 “The mission is fully validated,” ISRO said.
