Sriharikota: ISRO successfully launched its first satellite polarimeter of X rays on the Moon which will provide various knowledge about astronomical objects like black holes. ISRO’s ever reliable Polar Satellite Launch Vehicle (PSLV) in its mission C58 first launched from the launch platform at 10 am, beaming the main satellite polarometer. , Here. At the end of the countdown after 25 hours, the 44.4 meter high rocket touched down spectacularly and to thunderous applause from the spectators who had descended in large numbers at the spaceport, located about 135 km east of Chennai. The X-ray Polarimeter satellite (XPoSat) aims to investigate the polarization of intense X-ray sources in space. According to ISRO, it is the space agency’s first scientific satellite dedicated to research on space-time polarization measurements of X-ray emissions from celestial sources. Polarization of X rays serves as an important diagnostic tool to investigate the radiation mechanisms and geometry of celestial sources. The major utility payload of XPoSat is POLIX (X-ray Polarimetric Instrument), designed by the Institute for Investigation Raman and XSPECT (Spectroscopy and Timing) to measure polarimetry parameters. The life of the mission lasted for about five years.
