The Prime Minister, Narendra Modi today expressed happiness over the successful launch of XPoSat satellite by the Indian Space Research Organisation (ISRO).
He extended his best wishes to ISRO scientists along with the space fraternity for taking India to heights.
The Prime Minister posted on X:
“A great start to 2024 thanks to our scientists! This launch is wonderful news for the space sector and will enhance India’s prowess in this field. Best wishes to our scientists at ISRO and the entire space fraternity in taking India to unprecedented heights.”
About ‘XPoSat’ (X-ray Polarimeter Satellite): India’s first dedicated polarimetry mission to study various dynamics of bright astronomical X-ray sources in extreme conditions. The spacecraft will carry two scientific payloads in a low earth orbit. The primary payload POLIX (Polarimeter Instrument in X-rays) will measure the polarimetry parameters (degree and angle of polarization) in medium X-ray energy range of 8-30 keV photons of astronomical origin. The XSPECT (X-ray Spectroscopy and Timing) payload will give spectroscopic information in the energy range of 0.8-15 keV.
The emission mechanism from various astronomical sources such as blackhole, neutron stars, active galactic nuclei, pulsar wind nebulae etc. originates from complex physical processes and are challenging to understand. While the spectroscopic and timing information by various space based observatories provide a wealth of information, the exact nature of the emission from such sources still poses deeper challenges to astronomers. The polarimetry measurements add two more dimension to our understanding, the degree of polarization and the angle of polarization and thus is an excellent diagnostic tool to understand the emission processes from astronomical sources. The polarimetric observations along with spectroscopic measurements are expected to break the degeneracy of various theoretical models of astronomical emission processes. This would be the major direction of research from XPoSat by Indian science community.
