Key Points

The PSLV-C58 rocket carrying primary payload XPoSat and 10 other satellites will lift off at 9.10am from the Satish Dhawan Space Centre in Sriharikota...

The launch of X-Ray Polarimeter Satellite or XPoSAT, which would offer insights into celestial objects such as black holes onboard a Polar Satellite Launch Vehicle rocket on Monday morning comes after the success of its Gaganyaan Test Vehicle D1 mission in October.t...

The 44.4-meter-tall PSLV rocket would first deploy the primary satellite into a 650 km Low Earth Orbit around 21 minutes after lift-off and later the scientists would bring the satellite to a lower altitude of about 350 km by restarting the fourth stage of the vehicle, for conducting the PSLV Orbital Experimental Module-3 (POEM-3) experiment.According to the ISRO, the spacecraft will carry two scientific payloads in a low earth orbit..

The XSPECT (X-ray Spectroscopy and Timing) payload will give spectroscopic information in the energy range of 0.8-15 keV.The emission mechanism from various astronomical sources such as black hole, neutron stars, active galactic nuclei, pulsar wind nebulae, etc. originates from complex physical processes and are challenging to understand, the ISRO said..

This would be the major direction of research from XPoSat by the Indian science community, the ISRO said.Besides the ISRO, the US-based National Aeronautics Space Agency (NASA) conducted a similar study the Imaging X-Ray Polarimetry Explorer mission in December 2021 on the remnants of supernova explosions, the particle streams emitted by black holes and other cosmic events..
