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 revived his ‘dimagi Naxal’ remark while addressing the centenary celebrations of Shri Ram College of Commerce (SRCC) in Delhi on Saturday, using the term to criticise his opponents.

Speaking to students at the Delhi college, PM Modi described the phrase as a “homeopathic pill” and said it had prompted those he described as “dimagi Naxals” to come forward and reveal their views.

The prime minister also used his address to speak to Gen-Z about India’s development journey and asked students to consider the challenges the country had faced in the past.

PM Modi recalls past crises

During his speech, PM Modi referred to the 2013 Kedarnath disaster and the 2008 global financial crisis while criticising the handling of national emergencies by previous governments.

He said the government at the time of the Kedarnath disaster was shaken and questioned its ability to respond to the crisis.

Referring to the 2008 banking crisis, PM Modi alleged that the government of the time failed to effectively deal with the situation and claimed that India’s banking system was pushed close to collapse.

Prime minister lists challenges faced by his government

PM Modi also highlighted several major global crises that occurred during his government’s tenure.

He mentioned the COVID-19 pandemic, the Russia-Ukraine war, disruptions to global trade and supply chains, and the crisis in West Asia.

The prime minister said there had been concerns that India would struggle during these crises but argued that the country had continued to move forward.

PM Modi’s earlier SRCC visit

PM Modi had earlier visited SRCC in 2013, when he was the chief minister of Gujarat. His speech at the college received significant attention, particularly on social media, ahead of the 2014 Lok Sabha election.

His latest visit came during the college’s centenary celebrations, where his address focused on young people, India’s development ambitions and the challenges faced by the country.

India is on track to become the country with the second-largest metro rail network in the world after China, with Union Minister Manohar Lal saying the country could overtake the United States within the next two years.

India’s metro rail network has now expanded to 1,170 km across 26 cities. The network is only 216 km shorter than the US metro rail network, which stands at 1,386 km, according to figures cited by the minister.

India’s metro network expands rapidly

Speaking after the inauguration of an extended metro service in Indore, Manohar Lal highlighted the pace at which metro connectivity has grown in India.

He said metro services were operational across just 245 km in five cities when Prime Minister Narendra Modi assumed office in 2014. The network has since expanded to 1,170 km across 26 cities.

The minister said India could overtake the US in terms of metro rail network length in the next two years and become the world’s second-largest country in this segment after China.

China currently has around 8,000 km of metro rail lines, according to the figures cited by the minister.

Indore metro extension inaugurated

The minister made the remarks after inaugurating an extended section of the Indore metro. The project was built at a cost of around Rs 2,850 crore.

The Indore metro was earlier operating commercially on a six-km stretch between Gandhi Nagar and Super Corridor-3 stations. Following the extension, the service will operate on a 17-km route between Gandhi Nagar and Malviya Nagar Chauraha.

Madhya Pradesh Chief Minister Mohan Yadav said the metro service would mark a new phase in Indore’s development. He also said the network would eventually be extended to Ujjain and other nearby areas.

India’s metro rail network: Key figures

  • India currently has 1,170 km of operational metro rail network.
  • Metro services are operational across 26 cities.
  • The US has around 1,386 km of metro rail network.

PM Modi returns to SRCC after 13 years, revisits 2013 glass full speech

PM Narendra Modi returned to SRCC after 13 years for its centenary celebrations, revisiting themes from his landmark 2013 address.

PM Narendra Modi

Prime Minister Narendra Modi returned to Delhi University’s Shri Ram College of Commerce (SRCC) on Saturday, 13 years after his previous visit to the institution as Gujarat chief minister. 

His latest visit came as SRCC marked its centenary celebrations. Modi’s 2013 address at the college had attracted significant attention as he spoke about India’s youth, governance and the country’s demographic potential.

In 2013, Modi was Gujarat chief minister and had not yet been named the BJP’s prime ministerial candidate. He returned to the same campus this year as Prime Minister, having completed 12 years as Prime Minister and serving his third consecutive term. 

What PM Modi said at SRCC in 2013

The 2013 lecture was titled Emerging Business Models in the Global Scenario. The address also covered governance and India’s young population.

He described India’s youth as a source of national strength rather than simply a group of new-age voters. He also highlighted India’s demographic advantage and argued that the country needed to make better use of its young population.

One of the notable moments from the speech involved a glass of water.  Modi contrasted the conventional descriptions of a glass as half full or half empty and said he viewed it as full, with half containing water and the other half air.

The speech also included his remarks on technology and young Indians. Referring to an anecdote from a visit to Taiwan, Modi used the phrase “mouse-charmers” to describe Indians using computers and suggested that young Indians had the ability to influence the world through technology.

‘Minimum government, maximum governance’

Modi’s 2013 address also touched on governance. He spoke about the role of government and the need for better governance.

He also spoke about India’s potential in the 21st century. 

Modi returns as PM for SRCC centenary

The September 5 visit coincided with Teachers’ Day and SRCC’s 100th anniversary. The Prime Minister’s Office had announced that Modi would participate in the college’s centenary celebrations and address the gathering. SRCC was established in 1926 by industrialist and philanthropist Sir Shri Ram.

Earlier this year, Modi also met the SRCC governing body at his residence in April in connection with the college’s centenary celebrations and released a commemorative postage stamp marking the occasion. 

The return to SRCC came 13 years after his 2013 appearance at the college, when he addressed students as Gujarat chief minister.
