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: A man fell victim to an online scam, losing Rs 1.7 crore after fraudsters posed as officials from TRAI. According to a complaint filed at the CEN police station, the incident began on November 11, when the complainant received a call from an unknown number at 9:49 am.

The caller, claiming to represent TRAI, alleged that another mobile number registered under the complainant's name was involved in illegal activities in Andheri (East), Mumbai. The caller further stated that an FIR was lodged against the complainant for harassment under the guise of marketing. He was instructed to contact Andheri (East) police station immediately or risk his mobile service being deactivated within two hours.

The complainant was subsequently connected to an individual named Pradeep Sawant, who claimed the complainant was implicated in a money laundering scheme linked to the Naresh Goyal fraud case. Sawant alleged that a fraudulent bank account under the complainant's name was opened at Canara Bank, Andheri, and used to purchase a SIM card for illegal activities. He warned that the complainant could face arrest.

Later, the complainant was contacted via WhatsApp video call by individuals posing as Rahul Kumar (a police officer) and Akanksha (a CBI officer). They allegedly sent fabricated CBI documents to his WhatsApp number. The fraudsters demanded money to "resolve" the case. Fearing threats, the complainant allegedly transferred Rs 1.7 crore through RTGS in batches of Rs 53 lakh, Rs 74 lakh, and Rs 44 lakh between November 13 and 19. A case has been registered at the CEN police station and an investigation is ongoing.

Islamabad: Four paramilitary personnel and two policemen have been killed and over 100 security personnel injured as the protest by supporters of jailed former prime minister Imran Khan turned violent prompting the federal government to deploy the army in the national capital along with shoot at sight orders on Tuesday, state-run media said.

Pakistan deployed the army amid a tense stand-off with Khan's supporters from his Pakistan Tehreek-e-Insaf (PTI) pushing forward by removing hurdles on their way to Islamabad's D-Chowk venue as the government vowed to foil their attempt “even if a curfew needs to be imposed.”

Radio Pakistan said a vehicle rammed into Pakistan Rangers personnel killing four Rangers officials on the Srinagar Highway in Islamabad late on Monday night. Five other Rangers personnel and several police officials too sustained severe injuries.

About five kilometres from this spot, a bunch of miscreants, equipped with weapons and ammunition, pelted stones on the Rangers personnel and carried out indiscriminate firing on the security personnel at Chungi No 26 in Rawalpindi, Radio Pakistan said.

It also reported that two policemen were killed but didn't provide any details.

According to Punjab police, one policeman was killed at Hakla interchange on Islamabad outskirts during clashes with the PTI protestors on Monday but it also did not give details about the second policeman.

Separately, Interior Minister Mohsin Naqvi said, at a late night media interaction, that more than one hundred security personnel, mostly from police, were injured and added: “One senior police officer (SP) was critically injured – he suffered a severe head injury -- due to stone-pelting by protesters.”

Radio Pakistan further reported that the Pakistan Army was called in “to deal with the miscreants with an iron hand” and “clear orders have also been issued to shoot miscreants and troublemakers on sight.”

Strongly condemning the attack on Rangers and police personnel by protesters, Prime Minister Shehbaz Sharif, in a statement, directed to immediately identify those involved in the incident and ensure they are brought to justice.

“Attacks on police and Rangers, under the guise of a so-called peaceful protest, are condemnable,” he said, adding, the anarchist group seeks bloodshed and “Pakistan cannot afford any form of chaos or bloodshed. Bloodshed for nefarious political agenda is unacceptable and highly condemnable.”

He also instructed to provide the best possible medical facilities to those injured.

Interior Minister Naqvi said the government had offered an alternative venue to the protestors to stage their activity at Sangjani in the suburbs of the capital and apparently Khan has also agreed to it.

Despite permission given by Khan, “maybe there is a leadership above Imran Khan who has refused to accept this,” he claimed and confirmed that talks were going on with the PTI to resolve the issue and that the PTI leaders were allowed to meet Khan twice on Monday to get his input.

The government is waiting for a formal response to its offer of an alternative venue for protest and “we are now waiting for PTI’s response before taking further steps,” Naqvi added.

Naqvi also warned that “come what may, the PTI would not be allowed to stage a protest at D Chowk and even hinted of imposing a curfew if needed.”

Security sources also said that all necessary measures are being taken to counter terrorist activities by disruptive and extremist elements. “All the miscreants are also being identified to bring them to justice,” the sources added.

Meanwhile, the PTI accused the authorities of using violence in which several of its supporters have been injured. A PTI spokesman told BBC Urdu that at least two supporters have also been killed but it was not confirmed from other sources so far.

Khan, 72, the PTI founder, has been in jail since August 5, 2023, and had given the ‘final call’ for the protest to force the authorities to release all prisoners, including himself, and also restore the alleged stolen mandate or victory of his party in February 8 elections as well as rescind the last month's 26th constitutional amendment allowing the government more powers over judiciary.

Earlier on Sunday, led by Khyber-Pakhtunkhwa Chief Minister Ali Amin Gandapur and Khan's wife, Bushra Bibi, the PTI supporters began their journey from the militancy-hit province with a mission to make it to D-Chowk in the national capital but faced obstacles on the roads.

The D-Chowk, close to several important government buildings: the Presidency, the PM Office, the Parliament, and the Supreme Court, is a prime location in the national capital.

The authorities had blocked the highways by placing shipping containers but the protestors accompanied by lifting equipment and other heavy machines worked their way by removing hurdles, but the hurdles did skittle their speed and plans.

The convoy entered Islamabad from Sangjani toll plaza. The party also shared footage of the KP convoy in Islamabad’s limits.

The government already banned rallies by imposing Section 144, a colonial era law used to outlaw political activities, as a high level delegation from Belarus was visiting Pakistan.

At least one policeman was killed and dozen others injured in clashes on Monday as thousands of the PTI protestors entered the territorial jurisdiction of the national capital. In one of the clashes, a policeman was killed at the Hakla interchange on Islamabad outskirts.

Another constable of the Sargodha police was injured due to “firing by miscreants” and was being treated, local media said, adding, dozens of other policemen too were injured in the clashes, but exact details were not available.

As the convoy entered the capital territory in the evening, Bushra Bibi said in a video message: “My brothers, as long as Imran is not with us, we will not end this march.”

Meanwhile, as announced on Monday, all public and private educational institutions would remain closed in view of the law and order situation both at Islamabad and Rawalpindi on Tuesday.

Khan has been implicated in dozens of cases since his government was dismissed through a no-confidence motion in 2022. He has been in Adiala Jail at Rawalpindi since last year facing over 200 cases.

His party won the largest number of seats in the February general elections despite contesting as independents as the party was denied an election symbol.

The party founder has alleged that the ruling Pakistan Muslim League-Nawaz (PML-N) and its coalition partners, including the Pakistan Peoples Party (PPP), had “stolen the mandate” to grab power at the federal level.
