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.

PM Modi says Congress badly exposed after Kharge’s comments on election promises

“Now, they stand badly exposed in front of the people!” the Prime Minister said.

Reacting apparently to Congress chief Mallikarjun Kharge’s comment on poll promises, Prime Minister Narendra Modi on Friday slammed the grand old party, saying they are badly exposed in front of the people.

In Karnataka, Congress is busier in intra-party politics and loot instead of even bothering to deliver on development, the Prime Minister said in a post on X. “Not only that, they are also going to roll back existing schemes,” he claimed.

The Congress Party is realising the hard way that making unreal promises is easy but implementing them properly is tough or impossible, Modi said. “Campaign after campaign they promise things to the people, which they also know they will never be able to deliver. Now, they stand badly exposed in front of the people!” the Prime Minister said.

Earlier, Kharge made the guarantees remark while pulling up Karnataka Deputy Chief Minister D.K. Shivakumar over his statement that the state government would review the ‘Shakti’ guarantee.

“If we do not go as per the budget, we will go bankrupt and there will be no money to even develop roads. If this government fails, there will be nothing left to pass on to the next generation (of Congress leaders) except for the bad name and the latter has to bear the brunt for another 10 years,” he said while interacting with reporters.

However, Shivakumar on Friday said his statement on the ‘Shakti scheme’ was distorted and presented as if the Congress government in the state wanted to withdraw it.

“Check any state where the Congress has Governments today – Himachal Pradesh, Karnataka and Telangana- the developmental trajectory and fiscal health is turning from bad to worse. Their so-called Guarantees lie unfulfilled, which is a terrible deceit upon the people of these states,” PM Modi said.

The victims of such politics are the poor, youngsters, farmers and women, who are not only denied the benefits of these promises but also see their existing schemes diluted, he added.

“The people of the country will have to be vigilant against the Congress sponsored culture of fake promises! We saw recently how the people of Haryana rejected their lies and preferred a Government that is stable, progress oriented and action driven. There is a growing realisation across India that a vote for Congress is a vote for non-governance, poor economics and unparalleled loot. The people of India want development and progress, not the same old,” said PM Modi.

In Himachal Pradesh, salaries of Government workers are not paid on time, PM Modi claimed. The Prime Minister said, in Telangana, farmers are waiting for the waiver they promised.

Previously, in Chhattisgarh and Rajasthan Congress promised certain allowances which were never implemented for five years, he said. The Prime Minister said there are numerous such examples of how the Congress works.

Jammu and Kashmir Chief Minister Omar Abdullah on Friday paid the last rites of BJP leader Devender Singh Rana. Abdullah was accompanied by Deputy Chief Minister Surinder Choudhary, Ministers Satish Sharma and Javed Ahmed Rana, and Party Treasurer Shammi Oberoi.

The 59-year-old Rana, BJP MLA from Nagrota and brother of Union Minister Jitendra Singh, passed away on Thursday at a private hospital in Haryana’s Faridabad.

Rana is survived by his wife, Gunjan Rana, their daughters Devyani and Ketki, and son Adhiraj Singh.

“The terrible news from late last night isn’t really sinking in. I know the last few years have been marked by our differences Devender but I prefer to focus on the fun times we shared together, the excellent work we did together & the memories. You have been taken from us all too soon & will be missed. May your soul rest in peace now DSR. My heart goes out to your family as I struggle to find the words to convey my condolences to them,” the Chief Minister posted on X.

Apart from Omar Abdullah, Jammu and Kashmir BJP chief Ravinder Raina and Union Minister Gajendra Singh Shekhawat were among those who attended the last rites of Rana.

On his demise, the National Conference party said: “JKNC President Dr. Farooq Abdullah and Vice President & Chief Minister Omar Abdullah are deeply saddened to hear of the passing of Devender Rana, MLA Nagrota. They expressed their heartfelt condolences to his family, friends, and supporters, acknowledging his dedicated service and contributions to the people of J&K. The JKNC leadership and party members stand in solidarity with his loved ones during this difficult time.”

Earlier in the day, Prime Minister Narendra Modi mourned the demise of Rana and said he was a veteran leader who worked diligently towards Jammu and Kashmir’s progress.

“Shri Devender Singh Rana Ji’s untimely demise is shocking. He had just won the Assembly polls and had also played a noteworthy role in making the BJP stronger in J&K. In this hour of grief, my thoughts are with his family and supporters. Om Shanti,” PM Modi said on X.

In a post on X, Union Home Minister Amit Shah said Rana, who was always dedicated to the peace and development of Jammu and Kashmir and the interests of the people, made an invaluable contribution to the progress of the region. His demise is an irreparable loss for the BJP family, he added.

BJP chief JP Nadda also paid tribute to the party leader and said: “His dedication to public service and contributions towards the development of the people of Jammu & Kashmir will be remembered. His departure is an irreparable loss to the party”.

Two days after the disengagement between India and China, Indian troops started patrolling the Demchok sector in eastern Ladakh on Friday.

On Wednesday, both countries agreed to disengage and initiate coordinated patrols based on their understanding of the Line of Actual Control in the Demchok and Depsang sectors.

Patrolling by Indian troops in the Demchok sector of Eastern Ladakh kicked off Friday. Patrolling in the Depsang sector is expected to start soon, according to ANI. Coordinated patrolling means that both sides will be aware of each other’s patrol schedules.

Union Minister Kiren Rijiju said on Friday that he interacted with Chinese soldiers at Bumla Pass during the Diwali celebration with Indian Army personnel in Arunachal Pradesh’s Tawang district.

Sharing a video of him interacting with the Chinese soldiers on X, Rijiju said: “After talking to Chinese soldiers and seeing the infrastructures, everyone will feel proud of India’s border development now.”

The Union Minister said he also celebrated Diwali at the Army Helipad in Tawang. “It felt proud to celebrate Diwali with brave soldiers. Our country is safe only because of their dedication and courage. Jai Hind!” the senior BJP leader said.

On Thursday, soldiers from India and China shared sweets at various border locations in the Ladakh sector to celebrate Diwali. The exchange occurred at Hot Springs, Karakoram Pass, Daulat Beg Oldi, KongkLa, and the Chushul-Moldo border meeting point.

Additionally, Chief of Army Staff General Upendra Dwivedi emphasised that rebuilding trust along the LAC would be a gradual process, aiming to revert to the status quo of April 2020. He detailed that key measures—disengagement, de-escalation, and buffer zone management—are vital for alleviating tensions between the two nations. He also noted that this process would occur in phases, with each stage focusing on diminishing hostilities.

Chinese Ambassador to India Xu Feihong remarked that differences between neighboring countries like India and China are natural, but the critical aspect lies in how these differences are managed and resolved.

The border standoff began in eastern Ladakh in 2020 due to Chinese military actions and has led to prolonged tensions that have significantly affected relations between the two countries.
