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.

LPU students protest over reported rape allegation, police call it rumour

Students at Lovely Professional University protested over a reported rape allegation involving a worker, with police describing the claim as a rumour.

Published

on

Students of Lovely Professional University (LPU) in Punjab staged a protest after an allegation involving the reported rape of a student by a worker at the university surfaced.

The protest led to disruption around the university, with students taking to the streets and blocking the Jalandhar-Phagwara National Highway, according to the report.

The allegation triggered anger among students, who demanded action over the reported incident.

Police describe rape claim as rumour

Police, however, described the rape claim as a rumour, indicating that the allegation had not been established as a confirmed incident.

The distinction is important because the reported sexual assault allegation should not be treated as a confirmed rape unless investigators or other authoritative sources establish that fact.

The protests nevertheless continued as students sought clarity and action over the issue.

Protest disrupts traffic

The student demonstration also affected traffic on the Jalandhar-Phagwara National Highway. The protest brought attention to the allegations and the concerns being raised by students at the university.

With police calling the claim a rumour, further verification and investigation would be necessary to establish what actually happened.

Rahul-Gandhi

Opposition parties belonging to the INDIA bloc are set to meet in New Delhi on September 30 to discuss concerns surrounding the Election Commission, the Special Intensive Revision (SIR) of electoral rolls and a proposed removal motion against Chief Election Commissioner Gyanesh Kumar.

The proposed meeting comes amid growing coordination among opposition parties over the functioning of the poll panel and demands for action against Chief Election Commissioner Gyanesh Kumar. The parties are also discussing a possible joint response to the developments.

Why is the INDIA bloc meeting being planned?

The INDIA bloc meeting on September 30 comes amid reports of objections within the Election Commission over certain decisions and orders related to the SIR exercise. 

According to the report, Opposition leaders have been discussing a coordinated response to their concerns over the Election Commission and the electoral-roll revision process. 

The issue is also expected to be discussed at the Congress Working Committee meeting scheduled for September 29, a day before the proposed INDIA bloc meeting.

Gyanesh Kumar removal demand in focus

The demand for the removal of Chief Election Commissioner Gyanesh Kumar has become a major point of contention between the Opposition and the Election Commission.

The CPI(M), CPI and CPI(ML)-Liberation have demanded Kumar’s removal and an immediate halt to the SIR exercise. Congress has also intensified its criticism of the CEC.

Opposition parties are also working on a fresh removal motion against Gyanesh Kumar. The September 30 meeting is expected to finalise the strategy for the motion, including the collection of signatures. According to the report, this would be the Opposition’s third such attempt. 

What is the SIR controversy?

The political dispute is linked to the Special Intensive Revision of electoral rolls, or SIR.

The controversy intensified following a report that Election Commissioners Sukhbir Singh Sandhu and Vivek Joshi had recorded objections on several occasions concerning decisions and orders related to the SIR process.

The Election Commission has said that differing views and observations are part of normal deliberations in a multi-member constitutional body. The poll panel has also maintained that its orders have legal sanction and follow statutory procedures, while stating that the final decisions on the SIR were taken unanimously. 

TMC and Left parties coordinate over the issue

The developments have also brought the Trinamool Congress and the CPI(M) together on the Election Commission issue, despite their political differences in West Bengal.

CPI(M) general secretary M A Baby proposed an immediate meeting to discuss a joint strategy. According to the report, Mamata Banerjee spoke with M A Baby and Leader of Opposition Rahul Gandhi, after which the leaders settled on September 30 for the meeting. 

What could be discussed at the September 30 meeting?

The proposed meeting is expected to focus on:

  • Concerns surrounding the Election Commission
  • The Special Intensive Revision of electoral rolls
  • Opposition demands concerning CEC Gyanesh Kumar
  • A possible fresh removal notice against the CEC
  • A coordinated response by INDIA bloc parties

The exact agenda and participation will depend on the discussions among the opposition parties before the proposed meeting.
