X-Ray Polarimeter Satellite (XPOSAT)

ISRO's XPoSat was successfully launched from the Satish Dhawan Space Centre in Sriharikota, Andhra Pradesh.

About- India's inaugural scientific satellite to measure space-based polarization of X-ray emissions from celestial sources such as black holes and neutron stars in the medium energy band (8-30 keV).

• Orbit location - Low earth orbit (650 km), low inclination of 6 degree)
• Launch vehicle - PSLV C58
• Mission life - 5 years
• Payloads - The satellite carries 2 payloads.

XPoSAT is the 2^nd spacecraft in the world which will study celestial bodies using polarimetric techniques, after NASA's Imaging X-Ray Polarimetry Explorer (IXPE).

PSLV Orbital Experimental Module (POEM)

• The fourth stage of PSLV (PS4), also called the PSLV Orbital Experimental Module (POEM) will perform orbital experiments.Since this is the 3^rd time ISRO has used PS4 to exhibit orbital experiments, XPoSAT's PS4 is called POEM-3.
• The spent PS4 stage will be used to conduct in-orbit scientific experiments in microgravity conditions for an extended duration of 4-6 months.
• It derives power from the solar panels mounted around the PS4 tank and a Lithium-ion battery.
• POEM-3 is equipped with 10 payloads.
