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.

Gandhi said the BJP leaders and candidates are saying that they will change the Constitution. She said PM Modi is denying it and this is BJP’s tactic. Priyanka Gandhi was speaking at an election rally at Dharampur village of tribal dominated Valsad district, Gujarat held in support of Congress candidate for ST-reserved Valsad Lok Sabha seat, Anant Patel.

Gandhi said first the BJP will deny what they want to do. But after coming to power they will implement it. She further added the BJP wants to change the constitution to weaken the common people and deprive them of their rights given in the Constitution. She said the BJP leaders project the Prime Minister as powerful and say that chutki bajake ladai rukwa dete hai (he can stop the Russia- Ukraine war with the snap of his fingers). She asked why is Prime Minister unable to remove poverty just like that?

Priyanka Gandhi claimed the tribal population in Gujarat which is Modi’s home state and the whole country is suffering from issues like rising inflation, unemployment, low remumberation, loss of land, violence against women and other atrocities. She highlighted the Congress manifesto and said it addresses issues faced by the tribal population.

She assured the people that the Congress will bring schemes like MGNREGA for urban areas where families will get 100 days of guaranteed work. She said the Congress is committed to filing about 30 lakh vacancies in government jobs, providing subsidised diesel to fishermen and take the minimum wage to Rs 400. Gandhi said the Congress is going to work out sub plans for Scheduled Tribes and scheduled castes.
