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.

Bengaluru, Nov 22: For the second day running, the Karnataka BJP on Friday staged a statewide protest condemning the government’s alleged move to notify land of farmers as Waqf property.

The BJP staged a protest before the offices of Deputy Commissioners at district headquarters.

The BJP leaders are vehemently demanding that the state government cancel a 1974 Gazette notification in this regard.

The agitators are also demanding scrapping of the Waqf Board and the resignation of Chief Minister Siddaramaiah and Minister for Waqf and Housing Zameer Ahmad Khan.

The BJP MLAs, MLCs, MPs gathered in the premises of Freedom Park and staged a protest under the leadership of Leader of Opposition R. Ashoka and slammed the state government.

MLA T.S. Srivatsa led the protest in Mysuru and hundreds of party workers and farmers staged the protest under the leadership of former MP Pratap Simha in Kodagu.

Former MP Sumalatha Ambareesh led the agitation in Mandya.

This was the first time that Sumalatha took part in the party’s programme after the Lok Sabha elections.

State President B.Y. Vijayendra claimed, “The Congress government in Karnataka is issuing notices to farmers claiming the ownership of their lands to the Waqf Board and pushing them on the streets overnight.”

In the first week of December, three teams formed by the BJP will travel across the state and record the grievances of farmers.

“The state government is attempting to snatch away the lands belonging to temples as well,” Vijayendra alleged and added that the teams would comprise all senior leaders of the BJP.

Meanwhile, the police have taken Sri Ram Sena chief Pramod Muthalik into custody while staging a protest march to the office of Zameer Ahmad Khan in Bengaluru.

Muthalik along with Hindutva activists was planning to lay siege to Zameer’s office over the Waqf row.

The police stopped Muthalik and requested him to submit the memorandum by reaching the minister’s office in a vehicle. However, Muthalik refused to go with the police and continued his footmarch. The police took him into custody following arguments.

Iran’s Islamic Revolution Guards Corps (IRGC) has killed or captured 69 terrorists linked to the Israeli spy agency Mossad during a major counterterrorism drill in the country's southeast, its spokesman says.  

General Ahmad Shafaei, the spokesman for the “Martyrs of Security” drill, said Friday that a total of 23 terrorists have been killed and another 46 arrested in various clean-up operations ever since the IRGC Ground Force launched it in the Sistan and Baluchestan province on November 1.

Seven terrorists have also turned themselves in during the period.

“The undeniable fact about terrorists is that they rely on arrogant powers, particularly the intelligence service of the wicked and vicious Zionist regime," Shafaei said.

“Unfortunately, weapons and munitions at terrorists’ disposal are among the most sophisticated ones in the world. This accounts for their heavy dependence.” 

The official stated that several members of the disbanded terror teams were non-Iranian nationals, who had been hired by foreign intelligence agencies to carry out acts of sabotage and terror inside Iran.

In a most recent operation, six terrorists were arrested and four others were eliminated, three of whom were non-Iranians, he added. 

On October 26, ten members of Iran's law enforcement forces were killed in a terrorist attack in the Gohar Kuh district of Taftan in the Sistan and Baluchestan province.

The so-called Jaish al-Adl terrorist group claimed responsibility for the assault, which was one of the deadliest in the province in recent months.

The group has carried out numerous terrorist attacks in Iran, primarily in Sistan and Baluchestan.

Its tactics include the abduction of border guards as well as targeting civilians and police stations within the province to incite chaos and disorder.

In January, Iran launched a military operation during which the headquarters of the Pakistan-based terrorist group was targeted in missile strikes, destroying its infrastructure.

After the US prosecutors charged Gautam Adani with bribery and fraud, Congress reiterated its call for a Joint Parliamentary Committee (JPC) probe into the transactions of the Adani group, and hit out at Prime Minister Narendra Modi, alleging an "internal nexus" between him and "his favourite businessman."

Senior Congress leader Jairam Ramesh said the indictment of Gautam Adani and others by the US Securities and Exchange Commission validates his party’s call for a Joint Parliamentary Committee investigation.

The Congress has been pushing for the probe since January 2023, raising concerns over alleged irregularities involving Adani and his business dealings, said Ramesh.

Ramesh referred to the party’s “Hum Adani ke Hain” series, where 100 questions were raised about the alleged scams and the links between Prime Minister Narendra Modi and Gautam Adani.
He noted that the questions remain unanswered, reiterating the need for accountability in the matter.

The US prosecutors have charged Adani with deceiving investors by concealing information about his firm's solar energy project in India, which allegedly involved bribery.

Adani has been charged with securities fraud and conspiracy, according to an indictment unsealed on Wednesday. The case focusses on an agreement between Adani Green Energy Ltd. and another organisation to supply 12 gigawatts of solar power to the Indian government.

'BETRAYAL OF INDIAN INVESTORS'

Congress leader Pawan Khera described the allegations against Gautam Adani and his conglomerate as a “betrayal of Indian investors.”

Taking to X, Khera outlined the US charges, including claims that Adani’s group bribed Indian government officials between 2020 and 2024 to secure contracts. Citing media reports, he also pointed out that Gautam Adani personally met a government official to advance the scheme.

Khera referred to a March 2024 incident where the Adani Group allegedly misled the Bombay Stock Exchange and the National Stock Exchange, calling it a “grave violation of investor trust.”

He further highlighted a March 2023 FBI raid on the premises of Sagar Adani, Gautam Adani’s nephew, where electronic devices were seized as part of the investigation.

'SEBI NOT ABLE TO PROVE ANY CHARGES AGAINST ADANI'

Shiv Sena (UBT) leader Priyanka Chaturvedi criticised central probe agencies following US charges against Gautam Adani and others in an alleged bribery case linked to solar energy contracts.

Chaturvedi raised concerns about corporate governance and regulatory oversight in the country. “They talk about corporate governance, responsibility, and accountability. The industrialists should be asked to follow the rules and regulations, but even the agencies were defending him. The SEBI has not yet been able to prove charges against him,” she said, pointing to what she viewed as failures in ensuring accountability.

'BROUGHT DISREPUTE TO INDIA'

On US charges against Gautam Adani, AAP leader Sanjay Singh called for a probe against the industrialist. He said that the probe should be conducted by an investigation agency under the Supreme Court.

"Adani Group has brought disrepute to India. This is a very serious matter. The PM of India should come forward and answer this. All the pending matters against Adani should be probed by an investigation agency under Supreme Court monitoring, and all the corruption done by him, within and outside the country, should come out before the country and action should be taken against him," he said.

BJP DFENDS

BJP IT cell chief Amit Malviya responded sharply to the Opposition’s criticism regarding allegations involving Adani Green Energy and US-based Azure Power. He pointed out that the charges in the indictment are only allegations and emphasised, “The defendants are presumed innocent unless and until proven guilty.”

Malviya argued that the crux of the case concerns agreements to supply 12 GW of power to the Solar Energy Corporation of India (SECI), contingent on SECI securing power purchase agreements with state electricity distribution companies (SDCs).
