Context
The Indian Space Research Organisation, following a landmark 2023, will ring in the new year with the launch of the PSLV-C58 X-ray Polarimeter Satellite (XPoSat) mission.
Background
The Indian Space Research Organisation (ISRO) is set to embark on a groundbreaking mission with the launch of PSLV-C58, scheduled to lift off from the SatishDhawan Space Centre in Sriharikota. The focal point of this mission is the deployment of the XPoSat satellite, marking a significant milestone as ISRO's first dedicated scientific satellite for space-based polarization measurements of X-ray emissions from celestial sources.
The Science BehindXPoSat
- XPoSat carries two crucial payloads, namely POLIX (Polarimeter Instrument in X-rays) and XSPECT (X-ray Spectroscopy and Timing).
- Developed by the Raman Research Institute, POLIX is designed to measure the polarization of X-rays from various celestial bodies.
- On the other hand, XSPECT, developed by the Space Astronomy Group of URSC, Bengaluru, focuses on X-ray spectroscopy and timing measurements.
- These instruments are poised to unravel the mysteries of cosmic X-ray emissions, providing valuable insights into the nature of celestial phenomena.
Mission Objectives and Orbit Adjustment
- According to ISRO, the PSLV-C58 mission aims to launch XPoSatinto an eastward low inclination orbit.
- Following the injection of XPoSat, the PS4 stage will undergo two restarts to adjust the orbit, ultimately achieving a 350 km circular orbit.
