Major Space Missions By India: X-ray Polarimeter Satellite (XPoSat)

  • Launch Vehicle: PSLV­ – C58
  • Significance: It is India’s first dedicated polarimetry mission 
  • Aim: It aims to investigate the polarization of intense X-ray sources.
  • Orbit: Low Earth Orbit
  • Tenure: 5 years
  • The spacecraft will carry two scientific payloads in a low earth orbit.
    • POLIX (Polarimeter Instrument in X-rays) – This will measure the polarimetry parameters (degree and angle of polarization) in a medium X-ray energy range of 8-30 keV for photons of astronomical origin.
    • XSPECT (X-ray Spectroscopy and Timing) payload – It will give spectroscopic information in the energy range of 0.8-15 keV.
