Polar Satellite Launch Vehicle (PSLV). The ISRO will launch PSLV-C58/EXPOSAT Mission at 09:10 hrs IST on Monday, January 1, 2024. The launch is planned from Satish Dhawan Space Centre, Sriharikota.

ISRO's PSLV-C58 Mission will launch the XPOSAT Satellite into an eastward low inclination orbit. "After injection of XPOSAT, the PS4 stage will be re-started twice to reduce the orbit into 350 km circular orbit to maintain in 3-axis stabilized mode for Orbital Platform (OP) experiments," the space agency said. "The PSLV Orbital Experimental Module-3 (POEM-3) experiment will be executed meeting the objective of 10 identified payloads, supplied by ISRO and IN-SPACe," the ISRO said.

The spacecraft of the XPoSat will carry two scientific payloads in a low earth orbit. "The primary payload POLIX (Polarimeter Instrument in X-rays) will measure the polarimetry parameters (degree and angle of polarization) in medium X-ray energy range of 8-30 keV photons of astronomical origin. The XSPECT (X-ray Spectroscopy and Timing) payload will give spectroscopic information in the energy range of 0.8-15 keV," ISRO said.

1. To measure polarisation of X-rays in the energy band 8-30keV emanating from about 50 potential cosmic sources through Thomson Scattering by POLIX payload. 2. To carry out long term spectral and temporal studies of cosmic X-ray sources in the energy band 0.8-15keV by XSPECT payload. 3. To carry out polarisation and spectroscopic measurements of X-ray emissions from cosmic sources by POLIX and XSPECT payloads respectively in the common energy band.
