ISRO launches PSLV- C46, radar imaging earth satellite RISAT-2B

[vc_row][vc_column][vc_column_text]The Indian Space Research Organisation (ISRO) today (Wednesday, May 23) strengthened the defence power by successfully launching earth observation satellite RISAT-2B that would enhance the country’s surveillance capabilities among others.

As the 25-hour countdown which began on Tuesday concluded, the agency’s trusted workhorse Polar Satellite Launch Vehicle (PSLV-C46) blasted off at 5.30 am from the first launch pad of the Satish Dhawan Space Centre in Andhra Pradesh’s Sriharikota on its 48th mission, carrying the 615 kg satellite.

The RISAT-2B (Radar Imaging Satellite-2B), meant for application in fields such as surveillance, agriculture, forestry and disaster management support, was released into the orbit around 15 minutes after the lift-off.

It would replace the RISAT-2, which was successfully launched in 2009.[/vc_column_text][/vc_column][/vc_row][vc_row][vc_column][vc_raw_html]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[/vc_raw_html][/vc_column][/vc_row][vc_row][vc_column][vc_column_text]ISRO Chairman K Sivan had earlier described the mission as a “very, very important” one for the country.

“This is a very, very important mission for India. It is an excellent satellite with hi-fi earth observation (capabilities),” he had said.

The RISAT-2B is equipped with synthetic aperture radar that can take pictures of the earth during day and night, and also under cloudy conditions.

With a mission life of five years, the satellite would also be used for military surveillance, ISRO sources said.[/vc_column_text][/vc_column][/vc_row][vc_row][vc_column][vc_raw_html]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[/vc_raw_html][/vc_column][/vc_row][vc_row][vc_column][vc_column_text]The RISAT-2 has been actively used by India to monitor activities in camps across the border in Pakistan to thwart infiltration bids by terrorists.

The PSLV-C46 was the 14th flight of the PSLV in its core-alone configuration sans the use of the solid strap-on motors.

It was the 72nd launch vehicle mission from Sriharikota and also marked the 36th launch from the first launch pad.

Wednesday’s pre-dawn launch of the PSLV also marked the third launch in 2019.[/vc_column_text][/vc_column][/vc_row][vc_row][vc_column][vc_raw_html]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[/vc_raw_html][/vc_column][/vc_row][vc_row][vc_column][vc_column_text](With Inputs from agencies)[/vc_column_text][/vc_column][/vc_row]

Telegram CEO Pavel Durov criticises India restriction, says leak networks shifted to other apps

Telegram founder Pavel Durov has responded to India’s temporary restriction on the platform ahead of the NEET-UG 2026 re-examination, arguing that the move affected ordinary users without stopping alleged leak networks.

Telegram founder and CEO Pavel Durov has criticised India’s decision to temporarily restrict access to the messaging platform, arguing that the move failed to curb alleged exam leak operations and instead affected millions of legitimate users.

The restriction was imposed ahead of the NEET-UG 2026 re-examination as authorities sought to prevent the spread of leaked exam-related material and disrupt networks allegedly involved in malpractice.

In a public response, Durov said the action had inconvenienced a large number of users across India while those responsible for sharing leaked content had simply migrated to alternative platforms.

According to Durov, restricting access to Telegram did not eliminate the problem authorities were trying to address. He claimed that groups involved in distributing exam-related leaks quickly shifted their activities elsewhere, raising questions about the effectiveness of platform-specific restrictions.

The temporary curbs were announced by the government in the lead-up to the NEET-UG re-test scheduled for June 21. Officials said the move was aimed at safeguarding the integrity of the examination process following concerns about the circulation of leaked material online.

The restriction is currently expected to remain in place until June 22.

Durov also stressed that millions of Indian users rely on Telegram for communication, education, business activities and community engagement. He argued that measures targeting an entire platform can have wider consequences for users who have no connection to alleged wrongdoing.

The government’s action came amid broader efforts to prevent cheating and malpractice in competitive examinations. Authorities have been closely monitoring digital platforms and messaging services after reports that exam-related content was being circulated through online channels.

The debate has sparked discussions about how governments and technology platforms should balance examination security with access to digital communication services. While officials maintain that strong measures are necessary to protect the fairness of high-stakes examinations, critics argue that restrictions on entire platforms may not effectively stop determined offenders.

For now, Telegram remains at the centre of the discussion as authorities continue efforts to ensure a fair and secure conduct of the NEET-UG 2026 re-examination.

Telegram restricted ahead of NEET-UG re-exam, NTA backs move to curb exam fraud

NTA has welcomed the Centre’s decision to temporarily restrict Telegram ahead of the NEET-UG 2026 re-examination, citing the need to prevent fraud and misinformation.

The Centre has imposed temporary restrictions on messaging platform Telegram ahead of the NEET-UG 2026 re-examination, with the National Testing Agency (NTA) welcoming the decision as part of efforts to prevent exam-related fraud and misinformation.

The temporary curbs will remain in place until June 22, a day after the NEET-UG re-exam scheduled for June 21. Authorities said the action was taken following concerns that the platform was being misused by cheating networks and individuals circulating misleading claims related to the examination.

NTA says move aimed at protecting exam integrity

According to the NTA, the restrictions are intended to safeguard candidates from fraudulent activities and false information that could affect the fairness of the examination process. The agency stated that maintaining the integrity of the re-examination remains a priority as lakhs of students prepare to appear for the test.

The NEET-UG re-exam is being conducted after the original examination was cancelled amid allegations of question paper leaks and irregularities. Since then, authorities have been monitoring online platforms for suspicious activity and misleading content targeting candidates.

Restrictions linked to concerns over fake paper leak claims

In recent weeks, several reports surfaced about Telegram channels allegedly offering access to leaked examination papers. The NTA had repeatedly advised students not to trust such claims and referred suspicious links and posts for verification by cybercrime authorities. No official confirmation of any genuine leaked re-exam paper had been issued.

Authorities believe the temporary restrictions will help limit the spread of fake content and reduce opportunities for organised exam fraud in the days leading up to the re-test.

Wider efforts to secure the re-examination

The government and examination authorities have introduced several measures ahead of the re-exam, including monitoring social media platforms and creating channels for reporting suspicious claims related to NEET-UG 2026. The NTA has also urged candidates to rely only on official communications for updates regarding the examination.

With the re-examination approaching, officials say the latest action is part of a broader effort to ensure a fair and transparent process for all candidates.

Abhishek Banerjee

Trinamool Congress leader and Diamond Harbour MP Abhishek Banerjee on Tuesday said he would not bow to the BJP after spending nearly 11 hours being questioned by the Enforcement Directorate (ED) in connection with an ongoing investigation.

Speaking after the questioning, Banerjee alleged that central agencies were being used to target opposition leaders and asserted that he would continue his political fight despite what he described as sustained pressure.

The TMC leader has repeatedly maintained that investigations involving him are politically motivated, a charge he has made on several previous occasions while appearing before central agencies.

His appearance before the ED comes amid a period of heightened political activity and multiple investigations involving leaders in West Bengal. Recent days have also seen Banerjee face summons and questioning in separate matters by state investigative agencies.

After leaving the ED office, Banerjee reiterated that he would not be intimidated and said he remained committed to his political responsibilities. He also accused the BJP of attempting to weaken opposition parties through investigative action, an allegation that the BJP has rejected in the past.

The Enforcement Directorate has not publicly commented on Banerjee’s remarks. The investigation related to the questioning remains ongoing.
