Indian Space Research Organisation (ISRO) has introduced that India is set to launch its first X-Ray Polarimeter Satellite (XPoSat), aiming to examine the polarisation of intense X-Ray sources.
According to ISRO, whereas space-based X-Ray astronomy has been established in India, focusing predominantly on imaging, time-domain research, and spectroscopy, the upcoming XPoSat mission marks a serious worth addition. This analysis, supplementing conventional time and frequency area research, introduces a novel dimension to X-Ray astronomy, producing anticipation and pleasure inside the scientific neighborhood.
The XPoSat spacecraft is designated for commentary from Low Earth Orbit (non-sun synchronous orbit of ~650 km altitude, low inclination of roughly six diploma), carrying two scientific payloads. With these two payloads, the XPoSat mission is able to simultaneous research of temporal, spectral, and polarization options of the intense X-Ray sources.
The mission aims embody measurement of X-Ray polarization within the vitality band of 8-30 keV emanated from X-Ray sources, long-term spectral and temporal research of cosmic X-Ray sources within the vitality band of 0.8-15 keV.
The mission life is anticipated to be roughly 5 years. The payloads onboard XPoSat will observe the X-Ray sources throughout the spacecraft’s transit by means of the Earth’s shadow, i.e., throughout the eclipse interval.
The main payload of XPoSat, POLIX (Polarimeter Instrument in X-rays), is designed to measure polarimetry parameters —particularly the diploma and angle of polarization — within the medium X-ray vitality vary of 8-30 keV photons originating from astronomical sources. The POLIX payload was developed by the Raman Research Institute (RRI), Bengaluru, with help from varied ISRO centres.
The secondary payload is the XSPECT (X-ray Spectroscopy and Timing) payload, which can present spectroscopic data inside the vitality vary of 0.8-15 keV. The XSPECT payload was developed by the U.R. Rao Satellite Centre (URSC), ISRO.
The XPoSat shall be launched by the Polar Satellite Launch Vehicle (PSLV), from the Satish Dhawan Space Center in Sriharikota.
