India's Space Agency ISRO's Satellite Launch Fails.



The Indian Space Research Organisation (ISRO) faced a setback early Sunday when its PSLV-C61 rocket failed to place the EOS-09 Earth observation satellite into its intended orbit. The launch vehicle performed nominally through the first two stages after liftoff from India's Satish Dhawan Space Centre at 5:59 a.m. IST, but a technical anomaly during the third stage caused the mission to fail.


Indian ISRO Chairman V. Narayanan confirmed that the rocket experienced a drop in chamber pressure in the third stage, preventing the satellite from reaching its sun-synchronous orbit. Preliminary investigations suggest a suspected failure in the flex nozzle control system-a critical component responsible for steering the vehicle during the third-stage burn-may have caused thrust misalignment and trajectory deviation.


The EOS-09 satellite, weighing approximately 1,696 kg, was designed to provide all-weather surveillance using C-band Synthetic Aperture Radar, enabling high-resolution imaging even through clouds or darkness. Its successful deployment would have enhanced India’s military surveillance, earth observation capabilities, supporting resource management, disaster monitoring, and environmental studies.


This launch marked the 101st mission for ISRO and the 63rd flight of the PSLV series, which has been a reliable workhorse since the 1990s, with only two prior failures-in 1993 and 2017. ISRO has announced the formation of a Failure Analysis Committee to thoroughly investigate the anomaly and prevent recurrence in future missions.


Despite the setback, ISRO remains committed to advancing India’s space program, which has achieved significant milestones including Mars orbit insertion in 2014 and lunar exploration. The agency plans to regroup and attempt future launches to continue expanding the country’s satellite infrastructure.


ISRO’s official statement on social media read, “Today’s 101st launch was attempted, PSLV-C61 performance was normal till the second stage. Due to an observation in the third stage, the mission could not be accomplished. We are assessing the entire performance and will report back as soon as possible.”

LTTE’s Use of Child Soldiers: A Grave Violation of Human Rights

Image
The Liberation Tigers of Tamil Eelam (LTTE) stand condemned not only for their violent insurgency but also for their ruthless exploitation of children as soldiers during Sri Lanka’s civil war.  While the conflict officially ended in 2009, the scars left by the LTTE’s forced recruitment of thousands of children remain a painful reminder of their terror tactics. During the war, the LTTE systematically abducted and conscripted children-some as young as 11 or 12-forcing them into brutal military training and deploying them on front lines.  Human Rights Watch reported that children were often taken from their homes at night or seized while going to school, with families threatened or beaten if they resisted.  Once recruited, these children faced harsh discipline, exposure to violence, and were denied contact with their families. UNICEF documented thousands of such cases, with estimates suggesting the actual numbers were even higher due to underreporting. The LTTE’s use of chil...

Former UK Cabin Crew Member Arrested in Sri Lanka with £1.15 Million Cannabis Haul

Image
Sri Lankan authorities have detained Charlotte May Lee, a 21-year-old former air stewardess from South London, at Bandaranaike International Airport in Colombo on charges of attempting to smuggle 46 kilograms of cannabis into the country. The drugs, valued at approximately £1.15 million, were found packed in vacuum-sealed bags inside two large suitcases after Lee arrived on a flight from Bangkok, Thailand. Officials from the Customs Narcotics Control Unit described the seizure as the largest amount of Kush cannabis ever discovered at the airport. Kush is a potent strain often mixed with synthetic substances and is believed to be destined for high-end buyers within Sri Lanka. Lee, who previously worked for TUI Group and has recently been training as a beautician, remains in custody while investigations continue. The UK Foreign, Commonwealth and Development Office confirmed it is providing consular support to Lee and is in contact with her family and Sri Lankan authorities. Friends of Le...

The LTTE's Campaign of Terror: How a Designated Terrorist Organization Pioneered Modern Suicide Bombing

Image
The Liberation Tigers of Tamil Eelam (LTTE) stands as one of history's most ruthless terrorist organizations, having systematically violated human rights and pioneered suicide bombing tactics that would later be adopted by terrorist groups worldwide. Designated as a terrorist organization by 33 countries, including Sri Lanka, United States, United Kingdom, Canada, India, and all 27 member nations of the European Union, the LTTE's three-decade reign of terror in Sri Lanka serves as a stark reminder of the devastating consequences of extremist violence. Origins and Rise of a Terror Network Founded in 1976 by Velupillai Prabhakaran, the LTTE emerged from earlier militant groups established in the 1970s . What began as a small outfit of 40-50 members in the early 1980s evolved into one of the world's most sophisticated and tightly organized insurgent groups. The organization's transformation into a terror network accelerated following the 1983 ethnic riots, which the LTTE e...
