Recently, the Indian Space Research Organisation (ISRO) has announced that India is set to launch its first X-Ray Polarimeter Satellite (XPoSat).

About X-ray Polarimeter Satellite (XPoSat)

  • It is India’s first dedicated polarimetry mission to study various dynamics of bright astronomical X-ray sources in extreme conditions.
  • Aim: It is aiming to investigate the polarisation of intense X-Ray sources. 
  • The spacecraft will carry two scientific payloads in a low earth orbit.
    • POLIX (Polarimeter Instrument in X-rays): It will measure the polarimetry parameters (degree and angle of polarization) in medium X-ray energy range of 8-30 keV 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.
  • It is designated for observation from Low Earth Orbit (non-sun synchronous orbit of ~650 km altitude, low inclination of approximately six degree).
  • The 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.
  • It will be launched by the Polar Satellite Launch Vehicle (PSLV), from the Satish Dhawan Space Center in Sriharikota.

Q1) What is Imaging X-ray Polarimetry Explorer (IXPE) ?

IXPE is an international collaboration between NASA and the Italian Space Agency. It studies the most extreme and mysterious objects in the universe – supernova remnants, supermassive black holes, and dozens of other high-energy objects.
