India launches all-weather RISAT-1

Sriharikota, April 26: India's first indigenous all-weather Radar Imaging Satellite (RISAT-1), whose images will facilitate agriculture and disaster management, was today launched successfully on board the PSLV-C19 from here.

The 1,858 kg spacecraft, the country's first microwave remote sensing satellite, was injected into orbit by the Polar Satellite Launch Vehicle about 19 minutes after a perfect lift off at 5.47 am at the end of the 71-hour countdown from the Satish Dhawan Space Centre here, around 90 km from Chennai.

Indian Space Research Organisation's workhorse launch vehicle PSLV yet again proved its reliability completing its 20th successful flight in a row launching RISAT-1, the heaviest satellite ever lifted by it.

RISAT-1, culmination of nearly ten years of effort by ISRO, has the capability to take images of the earth during day and night as well as in cloudy conditions. Till now, India depended on images from a Canadian satellite as existing domestic remote sensing spacecraft cannot take pictures of earth during cloud cover.

Lifting off in the backdrop of crimson East from the first launch pad, the 44-metre tall rocket soared majestically into the sky in a mission described as 'a grand success' by ISRO Chairman K Radhakrishnan.

It was a textbook launch with each of the four stages of the rocket performing as programmed and the scientists at the mission control centre broke into cheers when the satellite was injected into orbit.

"I am extremely happy to announce that the PSLV C-19 mission is a grand success. This is the 20th successive successful flight of our PSLV. It injected precisely India's first radar imaging satellite into the desired orbit," a beaming Radhakrishnan said.

India had in April 2009 launched a Radar Imaging Satellite (RISAT-2) with all weather capability but it was bought from Israel for USD 110 million largely for surveillance purposes.RISAT-1 was launched using the state-of-the-art new Mission Control Centre for the first time after its inauguration by President Pratibha Patil in January, Mission Director P Kunhikrishnan said.

The launch of RISAT-1 was originally slated for March but the ISRO row, the fall-out of the punitive action against four former space scientists for their role in the Antrix-Devas deal, cast a shadow apparently delaying the preparations.

ISRO used PSLV-XL, high-end version, only third such instance, for today's launch. The XL version was earlier used for Chandrayaan-1 and GSAT-12 missions.

The approved cost of RISAT-1, including its development, is Rs 378 crore, while Rs 120 crore has been spent to build the rocket (PSLV-C19), making it a Rs 498-crore mission.

The spacecraft, which would be parked at its final orbit of 536 km altitude, has a mission life of five years and would make 14 orbits per day.

Besides use in the agriculture sector, RISAT-1 could also be used to keep round-the-clock vigil on the country's borders, but ISRO officials had said this satellite would not be used for defence applications. RISAT-2, primarily a spy spacecraft, is already doing that job.

RISAT-1's capability to take images in all weather conditions including fog and haze would be a boon for regions perennially under cloud cover.

The satellite carries a C-band Synthetic Aperture Radar (SAR) payload, operating in a multi-polarisation and multi-resolution mode to provide images with coarse, fine and high spatial resolutions respectively.

The unique characteristics of SAR enable applications in agriculture, particularly paddy monitoring in kharif season and management of natural disasters like flood and cyclone.

The satellite would be particularly useful in Kharif season when cloud-covered atmosphere is frequent. Images taken from the spacecraft of agricultural crops would enable planners with regard to production estimation and forecast.

During floods, aerial pictures would give a clear idea on the affected region and water level.

The Manipur Kuki MLAs have released a statement calling out Solicitor General Tushar Mehta's 'lies' in the Supreme Court. In a joint statement, the MLAs, including those from the Bharatiya Janata Party, said they had not had any meeting with the Chief Minister since May 3, 2023, nor did they intend to meet him in the future as “he was the mastermind behind the violence”.

As per the MLAs, the SG lied about state CM N Biren Singh speaking to Kuki MLAs to control the situation there, in order to halt a Supreme Court probe into the leaked tapes which allege that Singh has been complicit in the violence that broke out between Kukis and Meitis there.

"We...clarify that we have never had any meeting with Chief Minister, Shri N. Biren Singh since May 3, 2023, nor have any intention to meet him in future as he is the mastermind behind the violence and ethnic cleansing of our people from the Imphal valley, which is continuing till today, the latest being the brutal killing and burning of Mrs Zosangkim Hmar on November 7, 2024," the letter read, while condemning the recent 'barbaric' killing of the woman there, and noting the SG's assertion is 'tantamount' to misleading the top court.

“We, the undersigned ten MLAs, have come to know that during the Supreme Court hearing held on November 8, 2024, the Solicitor General of India submitted that ‘CM is meeting all Kuki MLAs and trying to bring the situation down to get peace’. In this connection, we hereby categorically state that this submission is a blatant lie and tantamount to misleading the Hon’ble Supreme Court of India,” the statement said.

The Supreme Court, while hearing a petition by a Kuki organisation, asked that it submit audio tapes to substantiate its claim that the Chief Minister was instrumental in inciting and organising violence in the northeastern State.

Solicitor-General Tushar Mehta orally informed the court that the Chief Minister was meeting all the Kuki-Zo MLAs and that peace in the State had come at a huge cost.

Union minister Amit Shah on Friday, November 15, said PM Narendra Modi will amend the Waqf Act despite opposition from leaders like Uddhav Thackeray and Sharad Pawar.

"Modi ji wants to change the Waqf Board law, but Uddhav ji, Sharad Pawar and Supriya Sule are opposing it," Shah said, addressing a rally at Umarkhed in Maharashtra's Yavatmal district.

"Uddhav ji, listen carefully, you all can protest as much as you want, but Modi ji will amend the Waqf Act," he said. Shah said there are two camps in the November 20 Maharashtra assembly polls, one of 'Pandavas' represented by the BJP-led Mahayuti and the other of 'Kauravas' represented by Maha Vikas Aghadi.

"Uddhav Thackeray claims that his Shiv Sena is the real one. Can the real Shiv Sena go against renaming Aurangabad to Sambhajinagar? Can the real Shiv Sena go against renaming Ahmednagar to Ahilyanagar? The real Shiv Sena stands with the BJP," Shah said.

"Rahul Baba used to say that his government would credit money in the accounts of the people instantly. You were unable to fulfil your promises in Himachal, Karnataka, and Telangana," he said.

Shah said the Mahayuti alliance has promised that women will get Rs 2,100 per month under the Ladki Bahin Yojana. "Kashmir is an integral part of India and no power in the world can snatch it away from us," Shah said.

The Taliban regime has appointed Ikramuddin Kamil as the acting consul in the Afghan mission in Mumbai, Afghan media has reported.

It is the first such appointment made by the Taliban set up to any Afghan mission in India.

There was no immediate comment from the Indian side on the appointment that came.

The Ministry of Foreign Affairs of Afghanistan has announced the appointment of Kamil as the acting consul in Mumbai, the Taliban-controlled Bakhtar News Agency reported on Monday, citing unnamed sources.

"He is currently in Mumbai, where he is fulfilling his duties as a diplomat representing the Islamic Emirate," it said.

The appointment is part of Kabul's efforts to strengthen diplomatic ties with India and enhance its presence abroad, the media outlet said

Kamil holds a PhD degree in international law and previously served as the deputy director in the department of security cooperation and border affairs in the foreign ministry, it said.

He is expected to facilitate consular services and represent the interests of Afghanistan in India, the report added.

Kamil's appointment comes days after the external affairs ministry's point-person for Afghanistan held talks with the Taliban's acting defence minister, Mullah Mohammad Yaqoob, in Kabul.

Sher Mohammad Abbas Stanikzai, the Taliban's deputy foreign minister for political affairs, also posted on X about Kamil's appointment.

The appointment of Kamil is seen as part of efforts to facilitate consular services to the Afghan population in Mumbai.

There has been almost negligible presence of diplomatic staff at the Afghan missions in India.

Most of the diplomats appointed by the Ashraf Ghani government have already left India.

In May, Zakia Wardak, the seniormost Afghan diplomat in India, resigned from her position after reports emerged that she was caught at the Mumbai airport for allegedly trying to smuggle 25 kg of gold worth Rs 18.6 crore from Dubai.

Wardak had taken charge as the acting ambassador of Afghanistan to New Delhi late last year, after working as the Afghan consul general in Mumbai for more than two years.

She took charge of the Afghan embassy in New Delhi last November, after the mission helmed by then ambassador Farid Mamundzay announced its closure.

Mamundzay, who was an appointee of the Ghani government, had moved to the United Kingdom.
