ISRO on Monday, 1 January, successfully launched its maiden X-Ray Polarimeter Satellite that would offer several insights into celestial objects like black holes.

ISRO’s ever-reliable Polar Satellite Launch Vehicle (PSLV) in its C58 mission, placed the primary X-Ray Polarimeter satellite XPoSat into a 650 Km Low Earth Orbit as intended after lifting off at the pre-fixed time of 9:10 am from the first launch pad in Sriharikota, Andhra Pradesh.

As the 25-hour countdown concluded, the 44.4-metre tall rocket lifted off majestically amidst thunderous applause from spectators who had descended on the spaceport, situated about 135 km east of Chennai.

The X-ray Polarimeter Satellite (XPoSat) is aimed to investigate the polarisation of intense X-ray sources in space.

According to ISRO, it is the first dedicated scientific satellite from the space agency to carry out research in space-based polarisation measurements of X-ray emission from celestial sources.

The X-ray polarisation serves as a crucial diagnostic tool for examining the radiation mechanism and geometry of celestial sources.

The primary payload of XPoSat is POLIX (Polarimeter Instrument in X-Rays) which is designed to measure polarimetry parameters by Raman Research Institute and XSPECT (X-ray Spectroscopy and Timing) built by the U R Rao Satellite Centre, Bengaluru. The Mission life is about five years.
