X-ray Polarimeter Satellite (XPoSat)

• Context (HT): ISRO will launch its first and the world’s second polarimetry mission, XPoSat.
• It is a project of ISRO and the Raman Research Institute (RRI), Bengaluru, Karnataka.
• XPoSat mission, in its five years of life, will measure the orientation of vibration in the light wave.
• The mission will capture the degree and angle of polarisation.

Mission Payloads

• POLIX (Polarimeter Instrument in X-rays), the primary payload, will measure the degree and angle of polarisation in the medium X-ray energy range originating from astronomical sources.
• The XSPECT (X-ray Spectroscopy and Timing) payload will provide spectroscopic information.
