New Delhi, Sept 3: The orbit of Chandrayaan-2's landing module 'Vikram' was successfully lowered for the first time on Tuesday and one final manoeuvre remained for India to pull off a historic soft-landing on the moon in the early hours of Saturday.

The 4-second de-orbiting operation was undertaken a day after the indigenously developed lander was separated from Chandrayaan-2's orbiter in a major milestone pushing India's second lunar mission into its last and most crucial leg--a controlled, soft-landing on the Moon.

The propulsion system on-board the lander was fired for the first time to lower its orbit after it started orbiting the moon independently, said the Indian Space Research Organisation(ISRO).

So far, all operations in the journey to the moon were carried out by the main orbiter of the 3,840-kg Chandrayaan-2 spacecraft that was launched into the earth's orbit on July 22 by the country's Geosynchronous Satellite Launch Vehicle, GSLV MkIII-M1.

The ISRO will perform one more de-orbiting manoeuvre on Wednesday, before the powered descent of 'Vikram' on September 7 for its landing in the lunar south pole.

A successful landing will make India the fourth country after Russia, the US and China to achieve a soft landing on the moon. But it will be the first to launch a mission to the unexplored south pole of the Moon.

"The first de-orbiting manoeuvre for Chandrayaan-2 spacecraft was performed successfully today (September 03, 2019) beginning at 0850 hrs IST as planned, using the onboard propulsion system. The duration of the manoeuvre was 4 seconds," the ISRO said giving the latest update on the Rs 978 crore Chandrayaan-2 mission.

"The orbit of 'Vikram' Lander is 104 km x 128 km. Chandrayaan-2 Orbiter continues to orbit the Moon in the existing orbit and both the Orbiter and Lander are healthy," it said, adding that the second and final manoeuvre to further lower the orbit is scheduled on September 4 between 3.30 and 4.30 am IST.

'Vikram' (with rover 'Pragyan' housed inside) is expected to touch down on the surface of the moon on September 7, between 1.30 and 2.30 am.

ISRO Chairman K Sivan has said the proposed soft-landing on the Moon is going to be a "terrifying" moment as it is something the space agency has not done before while the Lunar Orbit Insertion(LOI)manoeuvre was successfully carried out during the previous Chandrayaan-1 mission.

Following the landing, the rover 'Pragyan' will roll out from the lander between 5.30 and 6.30 am on September 7, and carry out experiments on the lunar surface for a period of one lunar day, which is equal to 14 earth days.

The mission life of the lander is also one lunar day, while the orbiter will continue its mission for a year.

Chandrayaan-2 satellite had began its journey towards the moon leaving the earth's orbit in the dark hours on August 14, after a crucial manoeuvre called Trans Lunar Insertion (TLI) that was carried out by ISRO to place the spacecraft on "Lunar Transfer Trajectory." In a major milestone, the spacecraft had successfully entered the lunar orbit on August 20 by performing the LOI operation.

The health of the spacecraft is being continuously monitored from the Mission Operations Complex (MOX) at ISRO Telemetry, Tracking and Command Network (ISTRAC) in Bengaluru with support from Indian Deep Space Network (IDSN) antennas at Bylalu, near Bengaluru, the space agency has said.

The orbiter carries eight scientific payloads for mapping the lunar surface and studying the exosphere (outer atmosphere) of the Moon while the lander carries three scientific payloads to conduct surface and subsurface science experiments.

The rover carries two payloads to enhance the understanding of the lunar surface.

According to the ISRO, the objective of the mission is to develop and demonstrate the key technologies for end-to-end lunar mission capability, including soft-landing and roving on the lunar surface.

On the science front, this mission aims to further expand knowledge about the moon through a detailed study of its topography, mineralogy, surface chemical composition, thermo-physical characteristics and atmosphere, leading to a better understanding of the origin and evolution of the moon, the space agency had said.

Mangaluru, Nov 24: The original departure time of 11.10 pm was a distant memory for scores of Dammam-bound passengers at Mangaluru International Airport last Friday night, as their Air India Express flight was abruptly cancelled at the eleventh hour, sparking hours of frustration and chaos.

The flight, IX 885, initially scheduled to depart at 11.10 pm on November 22, was subject to two back-to-back reschedules—first pushed to 11.45 pm and then significantly postponed to 1.40 am—before the final, crushing announcement of cancellation was made. For the travellers, many of whom are likely expatriate workers with tight schedules, the last-minute change marked the beginning of a distressing ordeal.

"There was no drinking water, no food, and absolutely no proper guidance. We were left stranded like refugees," complained a stranded passenger.

According to multiple passenger accounts, the airline's ground staff failed to provide adequate support or essential amenities following the cancellation. Complaints poured in about the total absence of drinking water, food provisions, and any reliable guidance from the carrier's representatives. Travellers alleged they were left stranded for a considerable period, with no immediate arrangements or clear communication offered regarding accommodation or alternative travel to send them back home.

The incident has highlighted serious concerns over the carrier's contingency planning and customer service protocols during flight disruptions at one of India's key international gateways. The airline is yet to issue a comprehensive statement addressing the alleged lapse in passenger care.

New York/Washington: US President Donald Trump has again claimed to have solved the conflict between India and Pakistan, repeating his assertion during a meeting with New York City Mayor-elect Zohran Mamdani in the Oval Office.

Mamdani flew to Washington DC for his first meeting with Trump in the White House on Friday. Trump said he “enjoyed” the meeting, which he described as “great.”

During remarks in the Oval Office, with Mamdani standing next to him, Trump repeated his claim that he solved the May conflict between India and Pakistan.

"I did eight peace deals of countries, including India and Pakistan,” he said.

On Wednesday, Trump had said he threatened to put 350 per cent tariffs on India and Pakistan if they did not end their conflict, repeating his claim that he solved the fighting between the nuclear-armed neighbours and that Prime Minister Narendra Modi had called him to say “we're not going to go to war.”

Since May 10, when Trump announced on social media that India and Pakistan had agreed to a “full and immediate” ceasefire after a “long night” of talks mediated by Washington, he has repeated his claim over 60 times that he “helped settle” the tensions between India and Pakistan.

India has consistently denied any third-party intervention. India launched Operation Sindoor on May 7, targeting terror infrastructure in Pakistan and Pakistan-occupied Kashmir in retaliation for the April 22 Pahalgam attack that killed 26 civilians. India and Pakistan reached an understanding on May 10 to end the conflict after four days of intense cross-border drone and missile strikes.

Mamdani emerged victorious in the closely-watched battle for New York City Mayor, becoming the first South Asian and Muslim to be elected to sit at the helm of the largest city in the US.

He had been the front-runner in the NYC Mayoral election for months and defeated Republican nominee Curtis Sliwa and political heavyweight former New York State Governor Andrew Cuomo, who ran as an independent candidate and was officially endorsed by Trump just hours before the elections.

Indian-descent Mamdani is the son of renowned filmmaker Mira Nair and Columbia University professor Mahmood Mamdani. He was born and raised in Kampala, Uganda and moved to New York City with his family when he was 7. Mamdani became a naturalised US citizen only recently, in 2018.

Mangaluru: Chaos erupted at Mangaluru International Airport (MIA) after IndiGo flight 6E 5150, bound for Mumbai, was repeatedly delayed and ultimately cancelled, leaving around 100 passengers stranded overnight. The incident highlights the ongoing country-wide operational disruptions affecting the airline, largely due to the implementation of new Flight Duty Time Limitations (FDTL) norms for crew.

The flight was initially scheduled for 9:25 PM on Tuesday but was first postponed to 11:40 PM, then midnight, before being cancelled around 3:00 AM. Passengers expressed frustration over last-minute communication and the lack of clarity, with elderly and ailing travellers particularly affected. “Though the airline arranged food, there was no proper communication, leaving us confused,” said one family member.

An IndiGo executive at MIA cited the FDTL rules, designed to prevent pilot fatigue by limiting crew working hours, as the cause of the cancellation. While alternative arrangements, including hotel stays, were offered, about 100 passengers chose to remain at the airport, creating tension. A replacement flight was arranged but also faced delays due to the same constraints, finally departing for Mumbai around 1:45 PM on Wednesday. Passengers either flew, requested refunds, or postponed their travel.

The Mangaluru delay is part of a broader crisis for IndiGo. The airline has been forced to make “calibrated schedule adjustments”—a euphemism for widespread cancellations and delays—after stricter FDTL norms came into effect on November 1.

While an IndiGo spokesperson acknowledged unavoidable flight disruptions due to technology issues, operational requirements, and the updated crew rostering rules, the DGCA has intervened, summoning senior airline officials to explain the chaos and outline corrective measures.

The ripple effect has been felt across the country, with major hubs like Bengaluru and Mumbai reporting numerous cancellations. The Mangaluru incident underscores the systemic operational strain currently confronting India’s largest carrier, leaving passengers nationwide grappling with uncertainty and delays.
