Sriharikota, Apr 1: ISRO's PSLV C-45 lifted off from the Satish Dhawan Space Centre here on Monday, carrying India's EMISAT satellite along with 28 nanosatellites of global customers.

As the 27-hour countdown concluded, the nearly 50-metre tall rocket, a new variant of ISRO's trusted workhorse PSLV-QL, blasted off from the second launch pad at the spaceport of Sriharikota, about 125 km from here, at 9.27 am.

The EMISAT satellite is aimed at electromagnetic measurement.

The mission marks several firsts to the credit of the space agency as it would manoeuvre satellites in various orbits and orbital experiments, including on maritime satellite applications.

According to ISRO, a new variant of the rocket PSLV-QL equipped with four Strap-On motors in the first stage is used for the launch.

PSLV, also used in India's two key missions, "Chandrayan" in 2008 and Mars Orbiter in 2013, is a reliable and versatile launch vehicle for ISRO with 39 consecutive successful flights till June, 2017 and five-in-a-row from January 2018.

The rocket has encountered only two failures so far, its maiden developmental flight ended unsuccessful way back in 1993.

In September, 2017, the flight went off without any hitch but the IRNSS-1H Satellite could not be released into orbit after the PSLV-C39's heat shield failed to open on reaching the orbit.

In this mission, ISRO scientists would place the satellites and payloads in three different orbits, a first for the agency.

After injecting the 436 kg primary satellite EMISAT, intended for electromagnetic spectrum measurement, at around 17 minutes from lift off in a 749 km orbit, they would restart the fourth stage again.

ISRO said this was the first time it has been envisaged to provide a micro-gravity environment for research organisations and academic institutes to perform experiments.

The PS4-fourth stage hosts three payloads in this mission.

They are automatic identification system from ISRO for maritime satellite applications capturing messages transmitted from ships.

Automatic Packet Repeating System from AMSAT (Radio Amateur Satellite Corporation), India to assist amateur radio operators in tracking and monitoring position data.

Advanced Retarding Potential Analyzer for lonospheric Studies (ARIS) from Indian Institute of Space Science and Technology (IIST) for the structural and composition studies of ionosphere.

The other 28 international satellites -- 25 3U type, two 6U type and one 2U type nano satellites -- are from Lithuania (two), Spain (one), Switzerland (one) and the United States (24).

All these satellites are being launched under commercial arrangements, the ISRO said.

In February, ISRO launched India's communication satellite GSAT-31 from the European launch service provider Ariane from French Guiana.

Since 1946, the United States has attempted 93 coups or “regime change” operations across the world — including two in Iran, US Special Envoy for Syria Tom Barrack has admitted.

Speaking to the UAE-based IMI Media Group, in remarks published by The National, Barrack said Washington tried twice to overthrow the Iranian government but failed both times. 

“For (Trump) then to be imputed with regime change — we had two regime changes in Iran already. Neither one worked. So I think wisely leave it to the region to solve,” said Barrack, who also serves as the US ambassador to Turkey.

His comments come six months after the US joined Israel in airstrikes against Iran during ongoing indirect nuclear negotiations between Tehran and Washington.

On June 13, Israel launched an attack on Iran that killed at least 1,064 people and hit civilian infrastructure. Days later, the United States targeted three nuclear facilities — Fordow, Natanz and Isfahan — in what Iran called a clear violation of international law. Iranian retaliation eventually forced a halt to the assault on June 24.

Barrack further claimed that US President Donald Trump and Foreign Secretary Marco Rubio are “not into regime change” and prefer a regional approach driven by Middle Eastern countries themselves. According to him, regional dialogue and non-interference by outside powers offer a more durable path forward.

He added that Washington is still open to an agreement with Tehran if Iranian authorities show “seriousness” and willingness to engage constructively.

However, Iran maintains the US has not shown readiness for meaningful talks. In an interview with Japan’s Kyodo News, Iranian Foreign Minister Abbas Araghchi said negotiations could advance only if Washington acknowledges Iran’s right to peaceful nuclear energy and lifts unilateral sanctions.

New Delhi, Dec 5: IndiGo CEO Pieter Elbers issued a public apology this evening after more than a thousand flights were cancelled today, making it the "most severely impacted day" in terms of cancellations. The biggest airline of the country cancelled "more than half" of its daily number of flights on Friday, said Elbers. He also said that even though the crisis will persist on Saturday, the airline anticipates fewer than 1,000 flight cancellations.

"Full normalisation is expected between December 10 and 15, though IndiGo cautions that recovery will take time due to the scale of operations," the IndiGo CEO said. 

IndiGo operates around 2,300 domestic and international flights daily.

Pieter Elbers, while apologising for the major inconvenience due to delays and cancellations, said the situation is a result of various causes.

The crisis at IndiGo stems from new regulations that boost pilots' weekly rest requirements by 12 hours to 48 and allow only two night-time landings per week, down from six. IndiGo has attributed the mass cancellations to "misjudgment and planning gaps".

Elbers also listed three lines of action that the airline will adopt to address the issue.

"Firstly, customer communication and addressing your needs, for this, messages have been sent on social media. And just now, a more detailed communication with information, refunds, cancellations and other customer support measures was sent," he said.

The airline has also stepped up its call centre capacity.

"Secondly, due to yesterday's situation, we had customers stranded mostly at the nation's largest airports. Our focus was for all of them to be able to travel today itself, which will be achieved. For this, we also ask customers whose flights are cancelled not to come to the airports as notifications are sent," the CEO said.

"Thirdly, cancellations were made for today to align our crew and planes to be where they need to start tomorrow morning afresh. Earlier measures of the last few days, regrettable, have proven not to be enough, but we have decided today to reboot all our systems and schedules, resulting in the highest numbers of cancellations so far, but imperative for progressive improvements starting from tomorrow," he added.

As airports witnessed chaotic scenes, the Directorate General of Civil Aviation (DGCA) stepped in to grant IndiGo a temporary exemption from stricter night duty rules for pilots. It also allowed substitution of leaves with a weekly rest period. 

Civil Aviation Minister Ram Mohan Naidu has said a high-level inquiry will be ordered and accountability will be fixed.

With IndiGo flight disruptions impacting thousands of passengers, the airline on Saturday said that it will offer full waiver on all cancellations/reschedule requests for travel bookings between December 5, 2025 and December 15, 2025.

Earlier in the day, the civil aviation ministry had directed the airline to complete the ticket refund process for the cancelled flights by Sunday evening, as well as ensure baggage separated from the travellers are delivered in the next two days.

In a post on X, titled 'No questions asked', IndiGo wrote, "In response to recent events, all refunds for your cancellations will be processed automatically to your original mode of payment."

"We are deeply sorry for the hardships caused," it further added.

Several passengers, however, complained of not getting full refund as promised by the airline.

Netizens have shared screenchots of getting charged for airline cancellation fee and convenience fee.

"Please tell me why u have did this airline cancellation charges when u say full amount will be refunded (sic)," a user wrote sharing a screenshot of the refund page.

"Well, but you have still debited the convenience charges," wrote another.

Passengers have also raised concerns about the "cancel" option being disabled on the IndiGo app. "First enable the 'Cancel' button on your App & offer full refund on tickets cancelled by customers between the said dates," wrote a user.

A day after the country's largest airline, IndiGo, cancelled more than 1,000 flights and caused disruptions for the fifth day on Saturday, the ministry said that any delay or non-compliance in refund processing will invite immediate regulatory action.

The refund process for all cancelled or disrupted flights must be completed by 8 pm on Sunday, the ministry said in a statement.

"Airlines have also been instructed not to levy any rescheduling charges for passengers whose travel plans were affected by cancellations," it said.

On Saturday, more than 400 flights were cancelled at various airports.

IndiGo has also been instructed to set up dedicated passenger support and refund facilitation cells.
