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, Oct 26: In a distressing case of online harassment, Surathkal police in Mangaluru have apprehended a man, identified as Shariq, on charges of cyber harassment that allegedly led a woman to attempt suicide. 

The case took a dark turn when the woman reported that her Facebook account was hacked, leading to an influx of explicit, threatening messages directed at her brother, Kishan, and friend, Harshith.

According to Commissioner of Police Anupam Agrawal, the complaint, registered on October 22, specifically accused Shariq of orchestrating the harassment. Summoned for questioning, Shariq’s mobile phones and social media accounts were initially reviewed, but no conclusive evidence surfaced.

The case escalated when the woman reportedly received more abusive messages on October 24, pushing her to a point of desperation. Following her suicide attempt, police intensified the probe, reaching out to social media platforms for further verification. 

The Surathkal police have filed charges under sections 78(1)(i), 351(1 & 2), and 3(5) of the BNS, with the investigation ongoing to uncover the full extent of the cyber harassment network.

Several Central Reserve Police Force (CRPF) schools across India were hit with hoax bomb threats on Tuesday, just days after an explosion occurred near a CRPF school in Delhi. The threats, sent via email late Monday night, targeted schools in Delhi and Hyderabad, according to sources.

Earlier this week, a bomb exploded outside a CRPF school in Delhi’s Rohini area, causing significant damage to nearby vehicles and property. Fortunately, no casualties or injuries were reported.

In response to the blast, Delhi Police confiscated CCTV footage from nearby markets as part of their investigation. Sources indicate that surveillance footage captured a suspect at the scene, wearing a white T-shirt, displaying suspicious behavior the night before the explosion.

Preliminary investigations revealed that the explosive device had been hidden in a polythene bag, buried in a shallow pit, and covered with garbage. The blast caused a hole in the school's boundary wall and shattered the window panes and signboards of nearby shops.

Following the incident, the Delhi Police registered a First Information Report (FIR) under Section 4 of the Prevention of Damage to Public Property Act, Section 3 of the Indian Explosives Act, and other relevant sections.

The FIR states, "A case of an explosion caused by an unknown explosive substance has been registered, and the investigation continues." It also details the damage, noting that the blast left a hole in the boundary wall and affected nearby structures.

The targeted schools serve children from CRPF and other paramilitary families, and the recent threats have heightened concerns. In response, Delhi authorities have placed the city on high alert, ramping up security measures, especially in markets, ahead of the Diwali festival.
