PSLV-C58 XPoSat: India launches satellite to study black holes from Sriharikota

On January 1, the PSLV-C58 rocket took off at 9.10 a.m. from this spaceport’s first launch pad, which is situated around 135 kilometres east of Chennai.

The Indian Space Research Organisation successfully launched India’s first X-Ray Polarimeter Satellite on Monday, or XPoSat, from the Satish Dhawan Space Centre in Sriharikota. The satellite is designed to provide information about celestial objects such as black holes. It was carried into space by a Polar Satellite Launch Vehicle rocket.

According to the ISRO, the PSLV-C58 rocket successfully launched payload XPoSat into Low Earth Orbit on its 60th flight.

On January 1, the PSLV-C58 rocket took off at 9.10 a.m. from this spaceport’s first launch pad, which is situated around 135 kilometres east of Chennai.

It is the first specifically designed ISRO scientific satellite to conduct studies on polarisation measurements of X-ray radiation from astronomical sources from space.

Aeronautics and Space Agency (NASA) studied supernova explosion remnants, black hole particle streams, and other cosmic occurrences in December 2021 with the Imaging X-Ray Polarimetry Explorer mission.

Although India has established space-based X-ray astronomy with an emphasis on imaging and time domain investigations, the space agency stated that Monday’s mission represents a significant contribution to the scientific community.

In order to conduct long-term spectral and temporal investigations of cosmic X-ray sources, the PSLV-C58 mission aims to measure the polarisation of X-rays in the energy band 8-30 keV emitted by about 50 possible cosmic sources.

When analysing the radiation process and geometry of astronomical sources, X-ray polarisation is an essential diagnostic tool. POLIX (Polarimeter Instrument in X-Rays), developed by the Raman Research Institute to determine polarimetry parameters, and XSPECT (X-ray Spectroscopy and Timing), constructed by the U R Rao Satellite Centre, Bengaluru, are the main payloads of XPoSat.

With the launch of its first X-Ray Polarimeter satellite, the ISRO ushered in the new year. Following the success of the Gaganyaan Test Vehicle D1 mission in October, the launch occurred.

India achieved unprecedented achievement in 2023 with the gentle landing of Chandrayaan-3 on the Moon’s south pole and the launch of Aditya-L1, the country’s first solar mission.

Following the momentous August 23 landing of Vikram Lander on the Moon, the Pragyan rover was sent out to explore the lunar south pole, which had not before been explored.

India’s current objectives include the Gaganyaan Mission, establishing Bharatiya Antariksha Station by 2035, and sending the country’s first person to the moon by 2040.

Prime Minister Narendra Modi on Thursday said Operation Sindoor demonstrated India’s firm response against terrorism and highlighted the country’s commitment to national security.

Marking one year of the operation, the Prime Minister praised the courage, precision and professionalism of the Indian armed forces. He said the military action was carried out in response to the Pahalgam terror attack that had claimed the lives of 26 civilians in 2025.

Operation Sindoor was launched on May 7, 2025, as a calibrated tri-services operation targeting terror infrastructure linked to cross-border terrorism. Reports said the operation showcased coordinated action by the armed forces and was seen as a major counter-terror response by India.

On the anniversary of the operation, PM Modi also changed the display pictures across his social media platforms, including X, Facebook, Instagram and WhatsApp. The image carried the text “Operation Sindoor” along with the Indian tricolour design.

The Indian Air Force also shared visuals and messages recalling the operation and highlighting India’s military response. A video released by the force described the operation as a strong message against terrorism and referred to the precision strikes carried out during the mission.

Operation Sindoor was launched following the Pahalgam terror attack, after which India carried out strikes on terror camps in Pakistan and Pakistan-occupied Kashmir, according to official statements and reports published at the time.

Vijay meets Tamil Nadu Governor again as TVK pushes to prove majority

TVK chief Vijay held another meeting with Tamil Nadu Governor Rajendra Vishwanath Arlekar as the party intensified efforts to secure majority support after emerging as the single-largest party in the Assembly elections.

Actor-turned-politician Vijay met Tamil Nadu Governor Rajendra Vishwanath Arlekar again on Thursday as his party, Tamilaga Vettri Kazhagam (TVK), continued efforts to prove it has enough support to form the next government in the state.

TVK emerged as the single-largest party in the 234-member Tamil Nadu Assembly after winning 108 seats, but it remains short of the majority mark of 118.

The Congress has extended support to TVK, adding five MLAs to Vijay’s side. However, the alliance still needs additional backing from other parties or independents to comfortably cross the halfway mark.

According to reports, the Governor has not yet been fully convinced that TVK currently has the required numbers to form a stable government. This has delayed clarity over the swearing-in ceremony and the formal invitation to form the government.

Political activity intensified after reports emerged that some AIADMK legislators were moved to a resort in Puducherry amid speculation over possible support to TVK. AIADMK leaders, however, publicly denied any internal crisis.

TVK sources have expressed confidence that the party will be able to demonstrate majority support during discussions with the Governor.

The Tamil Nadu election results marked a major political shift in the state, with TVK breaking the long-standing dominance of the DMK and AIADMK in its first Assembly election contest.

Prime Minister Narendra Modi on Thursday updated the display pictures of his social media accounts to mark the first anniversary of Operation Sindoor. The new image was seen across his profiles on X, Facebook, Instagram and WhatsApp channels.

The updated profile picture carries the text “Operation Sindoor” on a black background along with elements of the Indian tricolour. One of the letters in the word “Sindoor” has been stylised using vermilion, commonly associated with married Hindu women.

Operation Sindoor was launched a year ago by Indian defence forces and the Border Security Force along the western border. The anniversary was also marked by several Union ministers and NDA leaders, who changed their social media profile pictures in a similar manner.

External Affairs Minister S. Jaishankar and other senior leaders were among those who adopted the commemorative display image on social media platforms, according to reports.
