X-Ray Polarimeter Satellite

  • Indian Space Research Organisation (ISRO) has announced that India is set to launch its first X-Ray Polarimeter Satellite (XPoSat), aiming to investigate the polarisation of intense X-Ray sources.

About the mission

  • The XPoSat spacecraft is designated for observation from Low Earth Orbit, carrying two scientific payloads.
  • With these two payloads, the XpoSat mission is capable of simultaneous studies of temporal, spectral, and polarization features of the bright X-Ray sources.

The mission objectives include:

  • measurement of X-Ray polarization in the energy band of 8-30 keV emanated from X-Ray sources,
  • long-term spectral and temporal studies of cosmic X-Ray sources in the energy band of 0.8-15 keV.
  • Mission life is expected to be approximately five years.
  • The payloads onboard XpoSat will observe the X-Ray sources during the spacecraft’s transit through the
    Earth’s shadow, i.e., during the eclipse period.
  • The XpoSat will be launched by the Polar Satellite Launch Vehicle (PSLV), from the Satish Dhawan Space
    Center in Sriharikota.
  • XpoSat (X-ray Polarimeter Satellite) is India’s first dedicated polarimetry mission to study various dynamics of bright astronomical X-ray sources in extreme conditions.
  • The spacecraft will carry two scientific payloads in a low earth orbit.
