The Indian Space Research Organisation (ISRO) is all set to launch the country's first X-ray Polarimeter Satellite (XPoSAT) on January 1, inaugurating 2024 with a blast-off from Andhra Pradesh's Satish Dhawan Space Centre.

What is ISRO’s PSLV-C58 mission?

The PSLV-C58 mission will investigate the polarisation of intense X-rays from cosmic sources. It aims to enable long-term studies and understand the distribution of magnetic fields and the nature of accelerators in galactic cosmic X-ray sources.

Liftoff is scheduled for 09:10 am on Monday, marking the 60th launch for ISRO's trusted PSLV rocket series.

The PSLV will carry two key scientific payloads into low Earth orbit. POLIX, the primary instrument, will measure the degree and angle of X-ray photon polarisation in the 8-30 keV medium energy range from astronomical origins.

The secondary XSPECT payload offers spectroscopic data in the 0.8-15 keV range.

What’s the next motive?

Additionally, the PSLV Orbital Experimental Module Poem will also host several experimental satellites from private space companies. Poem utilises the rocket's fourth stage as an orbital platform for scientific experiments using non-separating payloads.

With this mission, ISRO plans to unlock new perspectives on energetic cosmic phenomena through pioneering X-ray polarimetry research. The launch marks a promising start to India's 2024 space ambitions.
