The country's heaviest rocket the Geosynchronous Satellite Launch Vehicle (GSLV) MarkIII D1 carrying communication satellite GSAT-19 lifted off from Sriharikota at 5.28 pm on Monday and was soon put in orbit successfully.

President Mukherjee tweeted: Heartiest congratulations to ISRO on historic launch of GSLV-Mk III D1. Nation is proud of this significant achievement.

In a series of tweets Prime Minister Narendra Modi also heaped praise on the dedicated ISRO scientists.

The PM said, "Congratulations to the dedicated scientists of ISRO for the successful launch of GSLV – MKIII D1/GSAT-19 mission... The GSLV – MKIII D1/GSAT-19 mission takes India closer to next generation launch vehicle and satellite capability. The nation is proud."

Congress President Sonia Gandhi on Monday congratulated the ISRO for the successful launch of GSLV MKIII-D1, saying it was another significant achievement which has made the nation proud. In a message, Gandhi said the ISRO had kept up the tradition of excellence in space sciences. Congratulating ISRO chairman A S Kiran Kumar, she said his team has made the nation proud once again on Monday.

ISRO Chief A S Kiran Kumar also took the opportunity to congratulate the entire team which worked on this project.

"It is a historic day.. both the GSLV Mk-III and the GSAT-19 launch have been successful.. we are looking forward to its (GSAT-19) operations," Kiran Kumar said.

"This month there are lot of activities. On June 23, there will be a PSLV (Polar Satellite Launch Vehicle) and on June 28, a GSAT-17 satellite launch," he added.

The ISRO scientists on Monday successfully launched the country's heaviest rocket GSLV-MkIII D1 carrying 3,136 kg communication satellite GSAT-19 from the spaceport of Sriharikota.

The 25-and-half hour countdown began on Sunday at 3.58 pm and was "progressing normally". Scientists were currently involved in the propellant filling operations of the heaviest GSLV-MkIII D1, officials said.

The rocket was scheduled for a lift off at 5.28 pm from second launch pad at the Satish Dhawan Space Centre, Sriharikota about 120kms from Chennai.

Till now, ISRO had to depend on foreign launchers for communication satellites weighing more than 2,300 kg. The GSLV MkIII-D1 is capable of lifting payloads of up to 4,000 kg into the Geosynchronous Transfer Orbit (GTO) and 10,000 kg into the Low Earth Orbit.

ISRO Chairman A S Kiran Kumar had said the mission is important as "it was the heaviest-ever rocket and satellite to be launched from the country".

GSLV MkIII-D1 is capable of lifting payloads (or satellites) of upto 4,000kgs into the Geosynchronous Transfer Orbit (GTO) and 10,000kg into the Low Earth Orbit.

Earlier, ISRO had launched the 3,404 kg GSAT-18 communication satellite from Ariane, French Guiana.

The GSLV-Mk III-D1 is a three-stage vehicle with indigenous cryogenic upper stage engine designed to carry heavier communication satellites into the GTO.

Today's mission augmented India's communication resources as a single GSAT-19 satellite is equivalent to having a constellation of six to seven of the older variety of communication satellites.

In 2014, ISRO had successfully tested the Crew module Atmospheric Reentry experiment with the flight GSLV MkIII. The module after making its re-entry deployed its parachutes as planned and splashed down in the Bay of Bengal.

New Delhi: Seventeen Indians are on board an Israeli-linked container ship that has been seized by the Iranian military amid heightened tensions between Iran and Israel.

Official sources said India is in touch with Iranian authorities through diplomatic channels, both in Tehran and in Delhi, to ensure the welfare and early release of the Indian nationals.

The Iranian action came amid increasing fears that Tehran may launch an attack on Israeli soil in retaliation to a strike on the Iranian consulate in Syria 12 days ago.

"We are aware that a cargo ship 'MSC Aries' has been taken control by Iran. We have learnt that there are 17 Indian nationals onboard," said a source.

"We are in touch with the Iranian authorities through diplomatic channels, both in Tehran and in Delhi, to ensure security, welfare and early release of Indian nationals," it said.

Reports said Iran's Islamic Revolutionary Guards seized MSC Aries on Saturday morning when it was sailing through the Strait of Hormuz.

The Supreme Court of India on Friday, April 26, rejected pleas seeking 100% cross-verification of votes cast using EVMs with a Voter Verifiable Paper Audit Trail (VVPAT) and said “blindly distrusting” any aspect of the system can breed unwarranted scepticism.

A bench of Justices Sanjiv Khanna and Dipankar Datta delivered two concurring verdicts. It dismissed all the pleas in the matter, including those seeking to go back to ballot papers in elections.

An EVM comprises three units – the ballot unit, the control unit and the VVPAT. All three are embedded with microcontrollers with a burnt memory from the manufacturer. Currently, VVPATs are used in five booths per assembly constituency.

EVM VVPAT case: Supreme Court issues two directives

1.    Justice Khanna directed the Election Commission of India to seal and store units used to load symbols for 45 days after the symbols have been loaded to electronic voting machines in strong rooms.

2.    The Supreme Court also allowed engineers of the EVM manufacturers to verify the microcontroller of the machines after the declaration of the results at the request of candidates who stood second and third. The top court said the request for the verification of the microcontroller can be made within seven days of the declaration of the results after payment of fees.

Option for candidates to seek verification of EVM programmes

•    Candidates who secure second and third position in the results can request for the verification of burnt memory semicontroller in 5% of the EVMs per assembly segment in a Parliamentary constituency. The written request to be made within seven days of the declaration of the results.

•    *On receiving such a written request, the EVMs shall be checked and verified by a team of engineers from the manufacturer of the EVMs.

•    Candidates should identify the EVMs to be checked by a serial number of the polling booth.

•    Candidates and their representatives can be present at the time of the verification.

•    After verification, the district electoral officer should notify the authenticity of the burnt memory.

•    Expenses for the verification process, as notified by the ECI, should be borne by the candidate making the request.
What did the Supreme Court say?

•    "If EVM is found tampered during verification, fees paid by the candidates will be refunded," the bench said.

•    "While maintaining a balanced perspective is crucial in evaluating systems or institutions, blindly distrusting any aspect of the system can breed unwarranted scepticism...," Justice Datta said.

Who filed the petitions?

NGO Association for Democratic Reforms, one of the petitioners, had sought to reverse the poll panel's 2017 decision to replace the transparent glass on VVPAT machines with an opaque glass through which a voter can see the slip only when the light is on for seven seconds.

The petitioners have also sought the court's direction to revert to the old system of ballot papers.

New Delhi:  Twenty-nine Maoists, including a senior rebel leader - Shankar Rao, who had a bounty of ₹ 25 lakh on his head - were killed by security forces during an encounter in Chhattisgarh's Kanker district on Tuesday afternoon. A huge quantity of weapons, including Ak-47 and INSAS rifles, were recovered. 

Three security personnel were injured in the gunfight, which took place in forests near the village of Binagunda after a joint team of District Reserve Guard and Border Security Force were attacked.

Two of the three injured are from the BSF. Their condition is stable but the third - from the DRG - is in critical care. All three received treatment at a local hospital and are to be shifted to a larger facility.

Sources said the fighting began at around 2 PM, when a joint DRG-BSF team was conducting an anti-Maoist operation. The DRG was set up in in 2008 to combat Maoist activities in the state, and the Border Security Force has been deployed extensively in the area to for counter-insurgency ops.

There was another encounter in the district last month, in which two people - a Maoist and a cop - were killed, and security forces recovered a gun, some explosives, and other incriminating materials.

Personnel from the DRG and Bastar Fighters, both units of the state police force, with the Border Security Force, were involved in that operation, officials told news agency PTI. The patrolling team was cordoning off a forested area when fired on indiscriminately, leading to the gun battle.

In November last year, while the state was voting in the first phase of an Assembly election, a gunfight broke out between security forces and Maoist rebels in the same district.

An Ak-47 rifle was recovered from the encounter site.

On the same day, while polling was taking place, Maoists fired at DRG personnel deployed near a polling station in Banda in Dantewada district.
