ISRO’s Aditya-L1 Spacecraft To Enter Its Final Destination Orbit Today; Know All Details Here
ISRO will perform the final manoeuvre on Saturday to inject Aditya-L1 spacecraft, the first space-based Indian observatory to study the Sun, into its final destination orbit, some 1.5 million kilometres from the Earth.
Aditya-L1 spacecraft to be placed on Lagrange point 1
According to ISRO officials, the spacecraft will be placed in a halo orbit around Lagrange point 1 (L1) of the Sun-Earth system, about 1.5 million km from the Earth. The L1 point is about one per cent of the total distance between the Earth and the Sun.
A satellite in a halo orbit around the L1 point has the major advantage of continuously viewing the Sun without any occultations/eclipses, they said, adding this will provide a greater advantage in observing solar activities and its effect on space weather in real-time.
“This manoeuvre (at around 4 pm on Saturday) will bind the Aditya-L1 to a halo orbit around L1. If we don’t do this, there is a possibility that it will continue its journey, maybe towards the Sun,” an ISRO official told on Friday.
On September 2, 2023, PSLV-C57 blasted off the Aditya-L1 spacecraft
The Polar Satellite Launch Vehicle (PSLV-C57) launched the Aditya-L1 spacecraft from the second launch pad of Satish Dhawan Space Centre (SDSC), Sriharikota, on September 2 last year. After a flight duration of 63 minutes and 20 seconds, it was successfully injected into an elliptical orbit of 235×19500 km around the Earth.
The spacecraft underwent a series of maneuvers thereafter and headed Sun-Earth Lagrange Point 1(L1), having escaped the Earth’s sphere of influence. The spacecraft carries seven payloads to observe the photosphere, chromosphere and the outermost layers of the Sun (the corona) using electromagnetic and particle and magnetic field detectors.
“Using the special vantage point L1, four payloads directly view the Sun and the remaining three payloads carry out in-situ studies of particles and fields at the Lagrange point L1, thus providing important scientific studies of the propagatory effect of solar dynamics in the interplanetary medium,” according to the space agency.
The suits of Aditya L1 payloads are expected to provide the “most crucial information” to understand the problem of coronal heating, coronal mass ejection, pre-flare and flare activities and their characteristics, dynamics of space weather, and propagation of particles and fields, officials said.
Aditya-L1 mission major goals
The major science objectives of the Aditya-L1 mission are, 1) Study of the Solar upper atmospheric (chromosphere and corona) dynamics. 2) Study of chromospheric and coronal heating, physics of the partially ionized plasma, initiation of the coronal mass ejections, and flares. 3) Observe the in-situ particle and plasma environment, providing data for the study of particle dynamics from the Sun. 4) Physics of the solar corona and its heating mechanism. 5) Diagnostics of the coronal and coronal loops plasma: Temperature, velocity and density. 6) Development, dynamics and origin of coronal mass ejections (CMEs). 7) Identify the sequence of processes that occur at multiple layers (chromosphere, base and extended corona) which eventually leads to solar eruptive events. 8) Magnetic field topology and magnetic field measurements in the solar corona. 9) Drivers for space weather (origin, composition and dynamics of solar wind).

Rahul Gandhi slams Nitish govt for lathi-charge on BPSC candidates
New Delhi, Dec 26: Congress leader Rahul Gandhi on Thursday slammed the Nitish government for lathi-charge on Bihar Public Service Commission candidates in Patna during their protest to demand the cancellation of the December 13 exams.
“I had said in Parliament that in the same way that Eklavya’s thumb was cut off, in the same way the thumbs of the youth are cut off by leaking the papers,” said the Leader of Opposition in Lok Sabha in a post on X.
“The latest example of this is Bihar. BPSC candidates are raising their voices against the paper leak and demanding cancellation of the exam. But to hide its failure, the NDA government is instead resorting to lathi-charge on the students,” he said, attaching a video of police lathi-charge on the social media platform.
Extending support to the protesters, the Gandhi scion said, “This is extremely shameful and reprehensible. Playing with the future of students will not be tolerated. We are with them and will fight to get them justice.”
The ongoing protests by BPSC candidates have escalated, leading to a contentious police response and legal action against protesters and alleged instigators.
The candidates began their dharna on December 18, demanding the cancellation of the entire BPSC examination. Their dissatisfaction grew when the BPSC cancelled the examination for only one centre and rescheduled it for January 4, 2025.
On Wednesday evening, protesters attempted to surround the BPSC office on this issue, prompting police action, including lathi-charge.
Patna Police have registered an FIR against protesters, some coaching institutes, and social media accounts allegedly involved in spreading misinformation and provoking candidates.
“Accounts such as BPSC Network, Study for Civil Services, Civil Adda, and UPSC Civil Service Examination have been flagged for allegedly misleading posts. We have registered an FIR against them and notices are being served,” said Anu Kumari, SDPO of (Sachiwalay) of Patna Police.
Anu Kumari said: “On Wednesday, the protesters illegally surrounded the BPSC office on Nehru Road, a vital route in Patna where protests are prohibited. Their actions disrupted public order, and the district administration used mild force to restore normalcy. We have appealed to the public to avoid paying attention to rumours circulating on social media.”

‘No Compromise On Law & Order’: Telangana CM Revanth Reddy Assures Support To Telugu Film Industry Amid Allu Arjun’s Pushpa 2 Stampede Row
After holding the meeting with Tollywood actors and filmmakers on Thursday, Telangana Chief Minister Revanth Reddy assured that the government stands with the Telugu film industry. According to the sources, in the meeting, CM Reddy asserted that there will be no compromise on law and order. He also said that celebrities must control their fans and the industry must be responsible.
The meeting was held at Telangana State Police Command and Control Centre at Banjara Hills in Hyderabad.
The delegation of influential people from Tollywood was led by Telangana Film Development Corporation (FDC) chairman Dil Raju. Among other attendees are actors like Nagarjuna, Varun Tej, Sai Dharam Tej, Kalyan Ram, Shiva Balaji, Adavi Sesh, Nithin, and Venkatesh.
Directors including Koratala Siva, Anil Ravipudi, K Raghavendra Rao, Prashanth Varma, Sai Rajesh and Producers like Suresh Babu, KL Narayana, Damodhar, Allu Aravind, BVSN Prasad, Chinna Babu among others are present in the meeting.
Earlier, on December 4, when Allu Arjun attended the premiere of Pushpa 2: The Rule at Sandhya Theatre, a massive crowd gathered to catch a glimpse of the actor, and chaos ensued when he waved to fans from the sunroof of his car. This led to the tragic death of a woman named Revathi and injuries to her child.
Following the incident, Allu Arjun was arrested and later released on bail after furnishing a Rs 50,000 bond.On Tuesday, actor Allu Arjun was questioned by Hyderabad police in connection with the tragic incident during the premiere of his film Pushpa 2.
The incident has also sparked political controversy. Telangana Chief Minister Revanth Reddy blamed Allu Arjun for the tragedy, stating in the Assembly that police had denied permission for any event at Sandhya Theatre due to safety concerns.
The actor, however, dismissed the allegations, calling them an attempt at “character assassination.” Earlier this year, Telangana Minister K Surekha linked former Minister and BRS leader KTR to the divorce of Tollywood actors Samantha and Naga Chaitanya, accusing KTR of tapping the phones of actors and blackmailing them.
Surekha’s remarks sparked massive controversy, with several BRS leaders as well as superstar and Naga Chaitanya’s father, Nagarjuna Akkineni, condemning the remarks.
