ISRO's Aditya-L1 completes first halo orbit around Sun-Earth L1 point
Bengaluru (PTI): India’s first solar mission Aditya-L1 spacecraft completed its first halo orbit around the Sun-Earth L1 point on Tuesday, ISRO said.
The space agency said its station-keeping manoeuvre on Tuesday ensured its seamless transition into the second halo orbit.
The Aditya-L1 mission, which is an Indian solar observatory at Lagrangian point L1, was launched on September 2, 2023 and was inserted in its targeted halo orbit on January 6, 2024.
According to ISRO, Aditya-L1 spacecraft in the halo orbit takes 178 days to complete a revolution around the L1 point.
During its travel in the halo orbit, Aditya-L1 spacecraft will be subjected to various perturbing forces that will cause it to depart from the targeted orbit, the space agency said.
"Aditya-L1 underwent two station-keeping manoeuvres on February 22 and June 7, respectively, to maintain this orbit. Today's third station-keeping manoeuvre has ensured that its travel continued in the second halo orbit path around L1,” ISRO said.
The agency explained that Aditya L1's journey around Sun-Earth L1 Lagrangian point involves modeling of complex dynamics.
The understanding of various perturbing forces acting on the spacecraft helped in determining the trajectory accurately and planning precise orbit manoeuvres, it added.
"With today's manoeuvre, the state-of-the-art flight dynamics software developed in-house at URSC-ISRO for the Aditya-L1 missions stands fully validated," ISRO said.

Kerala HC declines interim stay on screening of ''L2: Empuraan''
Kochi (PTI): The Kerala High Court on Tuesday declined to issue any interim order putting on hold the screening of Malayalam film 'L2: Empuraan' starring superstar Mohanlal.
Justice C S Dias ordered to issue notice to the Centre and the Censor Board seeking their stand on the plea by Thrissur-native V V Vijeesh who has claimed that continuing to show the movie poses a risk of inciting communal violence and disturbing public order.
It listed the matter for hearing after the vacation.
The court also questioned whether the petition was filed in publicity interest by the petitioner.
During the brief hearing of the matter, the court also asked what was the problem when the Censor Board had certified the film for public viewing.
It also expressed doubts about the petitioner's intention behind filing the plea.
It also pointed out that no case was filed anywhere against the movie.
The state government said that no case has been lodged against the film in Kerala.
Meanwhile, Antony Perumbavoor, one of the producers of the film, earlier in the day announced that the movie has undergone cuts to remove scenes of little over two minutes.
He said the decision to carry out the edit was a joint one of all the producers and actors, including Mohanlal and Prithviraj Sukumaran, and it was not out of fear of anyone.
The movie has faced intense criticism from the Sangh Parivar with regard to some portions of the film.
'L2: Empuraan', the second part of the 'Lucifer' movie, a trilogy planned by the Prithviraj-Mohanlal team, has become a topic of hot debate over its critique of right-wing politics and the covert mention of the Gujarat riots.
On March 27, the day of the movie's release, the Sangh Parivar vehemently criticised the film on social media, while the Congress and Left platforms celebrated the film for portraying the right-wing politics as "villainous".
