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: 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.

Historical Background

It’s on November 26, 1949, the Constituent Assembly of India formally adopted the Constitution.This date is commemorated to acknowledge the completion of nearly three years of drafting, debate, and refinement.

On January 26, 1950, the Constitution came into force, marking India’s transition from a dominion to a sovereign republic.

The date 26 January was chosen to honor the “Purna Swaraj” declaration made in 1930 that marked the relentless efforts & sacrifices of the many. 

Why Constitution Day is Celebrated

* To honor & remember the framers of the Constitution, especially Dr. B. R. Ambedkar, the Chairman of the Drafting Committee, & many others. 

* To remind the citizens of the values, responsibilities, and rights enshrined in the Constitution.

* To promote constitutional values & literacy among students, institutions, and the general public.

* To reaffirm the nation’s commitment to justice, equality, liberty, fraternity and secular values.

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.
