India’s first space-based mission to the Sun, Aditya-L1, took off successfully from the second launch pad of Satish Dhawan Space Centre here on Saturday, September 2, 2023, nine days after the country’s ambitious Chandrayaan-3 made a safe and soft landing on the unexplored south polar region of the Moon.

Indian Space Research Organisation (ISRO)’s most reliable workhorse PSLVC-57 launched the Aditya L1 spacecraft weighing 1,475 kg at 11.50 am, amid loud cheers from scientists gathered at the Mission Control Room here. The cost of the mission is said to be Rs 420 crore.

Initially, the spacecraft will be placed in a low earth orbit, which will be made elliptical to launch Aditya L1 towards the Lagrange point L1 using on-board propulsion. As the spacecraft travels towards L1, it will exit the earths’ gravitational Sphere of Influence (SOI) and if all goes well, the spacecraft will be placed in a halo orbit around the Lagrange point 1 (L1) of the Sun-Earth system in 125 days.

The L1 point is about 1.5 million km from the Earth, just 1 per cent of the 150 million km distance between the two. The distance to be travelled by Aditya L1 is four times more than Chandrayaan-3, which landed on the Moon on August 23 and is coming out significant findings.
Reaching the L1 point will give India a greater advantage of observing the solar activities continuously. All the measurements will be made from the Lagrange point L1, while L5 is a good vantage point for studying the Earth directed CME events and assessing the space weather, scientists said.

Of the seven payloads – all indigenously developed and made by ISRO and other organisations -- four will directly view and study the Sun, while the remaining three will conduct in-situ studies of particles and fields around the L1 point.

Placing a satellite in the halo orbit around the L1 point has the major advantage of continuously viewing the Sun without any occultation/ eclipses and provide a greater advantage of observing the solar activities and its effect on space weather in real time, scientists said.

Through this mission, ISRO hopes to get important scientific studies of the propagatory effect of solar dynamics in the interplanetary medium, while the payloads are expected to provide crucial information to understand the problem of coronal heating, coronal mass ejection, pre-flare and flare activities and their characteristics, dynamics of space weather, propagation of particle and fields.

By studying the Sun, ISRO said, scientists can learn much more about stars in the Milky Way as well as about stars in various other galaxies. Since various thermal and magnetic phenomena on the Sun are of extreme nature, Sun will serve as a good natural laboratory to understand those phenomena which cannot be directly studied in the lab.

The suit of Aditya L1 payloads are expected to provide most crucial information to understand the problems of coronal heating, Coronal Mass Ejection, pre-flare and flare activities, and their characteristics, dynamics of space weather, study of the propagation of particles, and fields in the interplanetary medium.

Mangaluru: The Ullal police have arrested Manohar, the owner of Vazco Beach Resort, and its manager Bharath in connection with the drowning of three college girls from Mysuru at the resort’s swimming pool on November 17.

City Commissioner of Police Anupam Agrawal confirmed the arrests, stating that a case has been registered under Section 106 of BNS. The bodies of the victims, all in their twenties, have been handed over to their parents. The women had arrived at the resort for a weekend getaway on November 16.

Following the tragic incident, the resort was sealed by officials led by Mangaluru Assistant Commissioner Harshavardhan. The trade license of the resort, issued on June 13, 2024, has been suspended, and the tourism department has temporarily revoked the resort's registration. These actions prohibit the resort from engaging in any tourism-related activities until further notice.

Someshwara TMC Chief Officer stated that the suspension was due to the resort's failure to implement adequate safety measures, which resulted in the loss of three lives. Further investigations are underway.

Bengaluru: An estimated overall 10.14 per cent voter turnout was recorded during the first two hours, since the voting began for bypolls to three Assembly segments in Karnataka on Wednesday, election officials said.

The voting began at 7 am and will go on till 6 pm.

More than seven lakh voters are eligible to cast their votes in about 770 polling stations in Shiggaon, Sandur and Channapatna, where a total of 45 candidates are in the fray.

While Channapatna recorded 10.34 per cent voter turnout till 9 am, it was 10.08 per cent in Shiggaon, and 9.99 per cent in Sandur, election officials said.

Voters, including women and elderly were seen queuing up in front of polling booths in these segments.

By-polls for Sandur, Shiggaon, and Channapatna are necessitated, as the seats fell vacant following the election of their respective representatives -- E Tukaram of Congress, former CM Basavaraj Bommai of BJP, and Union Minister H D Kumaraswamy of JD(S) -- to Lok Sabha in May elections.

As many as 31 candidates are in the fray from Channapatna, while Sandur and Shiggaon have six and eight contenders, respectively.

Elaborate security arrangements have been made in the three segments for the smooth conduct of the polls.

The by-polls will witness a straight fight between the ruling Congress and BJP in Sandur and Shiggaon segments, while in Channapatna, JD(S) which is part of the NDA alliance is in contest against the grand old party.

Among the three segments, Channapatna is considered to be a "high profile", where the contest is between C P Yogeeshwara, a five time MLA from the segment and former Minister, who joined the Congress quitting BJP ahead of nomination, and actor-turned -politician Nikhil Kumaraswamy, who is Kumaraswamy’s son and former PM H D Deve Gowda's grandson.

BJP's Bharath Bommai, son of Basavaraj Bommai, is fighting Congress Yasir Ahmed Khan Pathan, who had faced defeat against the former Chief Minister in the 2023 Assembly polls, in Shiggaon.

Bharath Bommai and his father cast their vote at a polling booth in Shiggaon segment.

In Sandur, Bellary MP Tukaram's wife E Annapurna of Congress is contesting from the seat vacated by her husband, against, BJP ST Morcha president Bangaru Hanumanthu, who is considered close to party leader and former mining barron G Janardhan Reddy.

Annapurna, Tukaram and other family members cast their votes at a booth in the segment.

With Nikhil Kumaraswamy and Bharath Bommai contesting, the third generation of Gowda and Bommai families are in the fray in this by-poll. Both their fathers and grandfathers have served as Karnataka's Chief Ministers in the past.

The Manipur Kuki MLAs have released a statement calling out Solicitor General Tushar Mehta's 'lies' in the Supreme Court. In a joint statement, the MLAs, including those from the Bharatiya Janata Party, said they had not had any meeting with the Chief Minister since May 3, 2023, nor did they intend to meet him in the future as “he was the mastermind behind the violence”.

As per the MLAs, the SG lied about state CM N Biren Singh speaking to Kuki MLAs to control the situation there, in order to halt a Supreme Court probe into the leaked tapes which allege that Singh has been complicit in the violence that broke out between Kukis and Meitis there.

"We...clarify that we have never had any meeting with Chief Minister, Shri N. Biren Singh since May 3, 2023, nor have any intention to meet him in future as he is the mastermind behind the violence and ethnic cleansing of our people from the Imphal valley, which is continuing till today, the latest being the brutal killing and burning of Mrs Zosangkim Hmar on November 7, 2024," the letter read, while condemning the recent 'barbaric' killing of the woman there, and noting the SG's assertion is 'tantamount' to misleading the top court.

“We, the undersigned ten MLAs, have come to know that during the Supreme Court hearing held on November 8, 2024, the Solicitor General of India submitted that ‘CM is meeting all Kuki MLAs and trying to bring the situation down to get peace’. In this connection, we hereby categorically state that this submission is a blatant lie and tantamount to misleading the Hon’ble Supreme Court of India,” the statement said.

The Supreme Court, while hearing a petition by a Kuki organisation, asked that it submit audio tapes to substantiate its claim that the Chief Minister was instrumental in inciting and organising violence in the northeastern State.

Solicitor-General Tushar Mehta orally informed the court that the Chief Minister was meeting all the Kuki-Zo MLAs and that peace in the State had come at a huge cost.
