India’s XPoSat Mission: Advancing Our Understanding of the Universe

India’s upcoming X-Ray Polarimeter Satellite (XPoSat) mission is set to revolutionize our understanding of the universe. Scheduled for launch on January 1, 2024, the mission aims to investigate the polarization of intense X-ray sources, positioning India at the forefront of space-based polarimetry.

Unveiling pictures of the Polar Satellite Launch Vehicle (PSLV) on the launch pad, the Indian Space Research Organisation (Isro) provided a glimpse into the grandeur of this groundbreaking mission. The PSLV will propel the XPoSat into a low Earth orbit, approximately 650 kilometers above the planet’s surface.

With a planned mission lifespan of at least five years, the XPoSat will orbit Earth at an altitude of 500–700 km. Equipped with two scientific payloads, this undertaking is a monumental achievement for India’s space exploration endeavors.

The primary payload, known as POLIX (Polarimeter Instrument in X-rays), will measure the degree and angle of polarization in the medium X-ray energy range of 8-30 keV photons of astronomical origin. This breakthrough tool will empower astronomers to gain insights into various aspects of celestial objects, from their magnetic fields to the nature of the electrons involved in radiation and scattering.

Complementing POLIX is the XSPECT (X-ray Spectroscopy and Timing) payload, which will provide valuable spectroscopic information within the energy range of 0.8-15 keV. These combined scientific instruments will enable XPoSat to conduct long-term spectral and temporal studies of cosmic X-ray sources, further expanding our understanding of the universe.

With this ambitious mission, India is poised to break new ground in the realm of space exploration and scientific discovery. By focusing on X-ray polarimetry, XPoSat will unlock exciting possibilities for astronomers and astrophysicists, paving the way for even more remarkable achievements in our quest to comprehend the vastness of the cosmos.
