ISRO launches X-Ray satellite ‘XPoSat’ for Black Hole and Neutron Star studies

On the first day of 2024, Prime Minister Narendra Modi congratulated the scientists of the Indian Space Research Organization (ISRO) on the successful launch of the first X-ray satellite, known as ‘XPoSat’. The purpose of this spacecraft is to research neutron stars and black holes.

Modi expressed his happiness at the launch, highlighting how it will improve India’s standing in the space industry and characterizing it as a display of the country’s space capabilities. He wished the ISRO scientists and the space community all the very best for their efforts in taking India to new heights.

ISRO marked the commencement of its space missions in 2024 with the launch of the X-ray Polarimeter Satellite (XPoSat) from the Satish Dhawan Space Centre in Sriharikota, Andhra Pradesh. The satellite, lifted off at 9:10 am, is India’s first dedicated scientific satellite for researching space-based polarization measurements of X-ray emissions from celestial sources.

ISRO Chief S Somanath applauded the successful launch, highlighting the significance of this achievement in initiating the New Year. He announced that the PSLV-C58 rocket, in its 60th mission, effectively placed the XPoSat into Low Earth Orbit, fulfilling the mission’s objectives.

The primary payload of XPoSat was crafted by the Raman Research Institute, and the second payload was developed by the Astronomy Group of URSC (U R Rao Satellite Centre).

The primary goals of the PSLV-C58 mission include measuring the polarization of X-rays in the energy band of 8-30 keV from approximately 50 potential cosmic sources. This mission aims to conduct long-term spectral and temporal studies of cosmic X-ray sources, utilizing X-ray polarization as a vital diagnostic tool for examining the radiation mechanism and geometry of celestial sources.
