Orbit of Chandrayaan-2’s lander lowered, one step closer to Moon landing

Agencies
September 3, 2019

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.

IndiGo, India’s largest airline, is battling one of its worst operational disruptions in recent years, with hundreds of delays and cancellations throwing domestic travel into chaos.

Government data on Tuesday showed its on-time performance plunging to 35%, an unusual dip for a carrier long associated with punctuality.

By Wednesday afternoon, airports in Delhi, Mumbai, Bengaluru and Hyderabad had collectively reported close to 200 cancellations, stranding travellers across the country.

Crew Shortage After New Duty Norms

A major trigger behind the meltdown is a severe crew shortage, especially among pilots, following the rollout of revised Flight Duty Time Limitation (FDTL) norms last month.

The rules mandate longer rest hours and more humane rosters — a shift IndiGo has struggled to incorporate across its vast network.

Sources said several flights were grounded due to lack of cabin crew, while some delays stretched upwards of eight hours.

With IndiGo controlling over 60% of India’s domestic aviation market, the ripple effect has impacted airports nationwide.

IndiGo Issues Apology, Lists “Compounding Factors”

In a statement, IndiGo acknowledged the large-scale disruption:

“We sincerely apologise to customers. A series of unforeseen operational challenges — technology glitches, winter schedule changes, adverse weather, system congestion and updated FDTL norms — created a compounding impact that could not have been anticipated.”

To stabilise operations, the airline has begun calibrated schedule adjustments for the next 48 hours, aiming to restore punctuality. Affected passengers are being offered refunds or alternate travel arrangements, IndiGo said.

What the FDTL Rules Require

The FDTL norms, designed to reduce pilot fatigue, cap duty and flying hours as follows:
•    Maximum 8 hours of flying per day
•    35 hours per week
•    125 hours per month
•    1,000 hours per year

Crew must also receive rest equalling twice the flight duration, with a minimum 10-hour rest period in any 24-hour window.

The DGCA introduced these limits to enhance flight safety.

Hyderabad: 33 Flights Cancelled, Long Queues Reported

Hyderabad’s Rajiv Gandhi International Airport saw heavy early-morning crowds as 33 IndiGo flights (arrivals and departures) were cancelled.

The airport clarified on X that operations were normal, advising passengers to contact IndiGo directly for latest flight status.

Cancellations included flights to and from Visakhapatnam, Goa, Ahmedabad, Delhi, Bengaluru, Chennai, Madurai, Hubli, Bhopal and Bhubaneswar.

Bengaluru: 42 Flights Disrupted

Bengaluru’s Kempegowda International Airport recorded 42 cancellations — 22 arrivals and 20 departures — affecting routes to Delhi, Mumbai, Chennai, Hyderabad, Goa, Kolkata and Lucknow.

Passengers Vent on Social Media

Irate travellers took to X to share their experiences. One passenger stranded in Hyderabad wrote: “I have been here since 3 a.m. and missed an important meeting.”

Another said: “My flight was pushed from 1:55 PM to 2:55 PM and now 4:35 PM. I was informed only three minutes before entering the airport.”

Delhi Airport Hit by Tech Glitch

At Delhi Airport, the disruption deepened due to a slowdown in the Amadeus system — used for reservations, check-ins and departure control.

The technical issue led to longer queues and sluggish processing, adding to delays already worsened by staff shortages.

Bengaluru, Nov 27: Karnataka Chief Minister Siddaramaiah’s camp is reportedly on alert as the Congress leadership tussle in the state intensifies, particularly amid speculation over the potential promotion of Deputy Chief Minister D.K. Shivakumar. Siddaramaiah is said to be in a “wait-and-watch” mode after admitting to “confusion” earlier this week and urging the party to “put a full stop” to it.

Sources say his supporters are ready to act if senior leaders — including party chief Mallikarjun Kharge, Sonia Gandhi, and Rahul Gandhi — give any indication of backing Shivakumar. If the party insists on a leadership change, Siddaramaiah’s camp has a list of alternatives, underscoring the deep rift between the two leaders. One possible candidate is Home Minister G. Parameshwara, a Siddaramaiah loyalist and influential Dalit leader.

The strategy was reportedly finalized at a meeting led by PWD Minister Satish Jarkiholi, another Siddaramaiah supporter, who stressed that Delhi leaders need to resolve the issue. Kharge and the Gandhis are expected to meet soon, after which Siddaramaiah and Shivakumar may be summoned to Delhi.

Shivakumar has largely stayed non-confrontational, publicly endorsing Siddaramaiah and downplaying speculation about his own ambitions. However, he has made pointed comments emphasizing the importance of honoring promises, directed at Siddaramaiah.

The feud traces back to the 2023 state election, when Siddaramaiah was chosen as Chief Minister while Shivakumar, who led the party’s campaign, was made Deputy CM and state party chief — a departure from the Congress’ usual “one post per person” rule.

There were also hints of a prior understanding that Siddaramaiah would step down midway through the term. As the halfway mark passed last week, Shivakumar-aligned lawmakers have ramped up pressure on the party for a leadership change, with Shivakumar himself hinting at stepping down as state party chief to pursue the top job.

Udupi: The Malpe Police have arrested two men from Uttar Pradesh for allegedly sharing classified information related to Indian Navy vessels with individuals in Pakistan, posing a serious threat to national security.

According to a complaint filed by the CEO of Udupi Cochin Shipyard, Malpe—an institution under the Union Ministry of Ports, Shipping and Waterways—the prime accused, Rohit (29), was working as an insulator through subcontractor M/S Shushma Marine Pvt Ltd. He had earlier served at Cochin Shipyard Limited in Kochi, Kerala, where naval ships are under construction.

Udupi SP Hariram Shankar said the accused had unlawfully shared, via WhatsApp, confidential identification numbers of Navy-related ships and other classified details while working in Kerala, allegedly for illegal gains.

After joining the Malpe shipyard unit, Rohit reportedly continued collecting sensitive information through a friend in Kochi and circulated it to unauthorised individuals, violating national security protocols and potentially endangering India’s sovereignty, unity, and integrity.

Based on the complaint, Malpe Police registered a case under Section 152 of the Bharatiya Nyaya Sanhita (BNS) and Sections 3 and 5 of the Official Secrets Act, 1923.

A police team led by Karkala Subdivision Assistant Superintendent of Police Harsha Priyamvada—along with PSI Anil Kumar D, ASI Harish, and PC Ravi Jadhav—conducted the investigation and arrested the two accused, identified as Rohit (29) and Santri (37), both residents of Sultanpur district, Uttar Pradesh.

The duo was produced before the court, which remanded them in judicial custody till December 3. Further investigation is in progress.
