Science & Technology | Dated: 01 Jan 2026

The Indian Space Research Organisation (ISRO) successfully launched the X-ray Polarimeter Satellite (XPoSat) aboard the PSLV-C58 rocket from Sriharikota, Andhra Pradesh. This is India’s first dedicated polarimetry mission to study the dynamics of bright astronomical X-ray sources like black holes, neutron stars, and active galactic nuclei in extreme conditions.

🎯 Key Highlights:

  • XPoSat carries two payloads: POLIX (Polarimeter Instrument in X-rays) developed by Raman Research Institute and XSPECT (X-ray Spectroscopy and Timing).
  • India is only the second country after the USA (NASA's IXPE mission) to launch such a mission.
  • The mission life is expected to be five years, operating in a low earth orbit of 650 km.

💡 Other Important Facts:

  • Mission: XPoSat.
  • Rocket: PSLV-C58.
  • Significance: 2nd globally after NASA to study X-ray polarization.
