ISRO Launches XPoSat for Cosmic Research

The Indian Space Research Organisation (ISRO) commenced 2024 with a milestone by successfully launching the X-ray Polarimeter Satellite (XPoSat), aims to enhance our understanding of black holes and neutron stars. It was deployed into orbit using the PSLV-C58 rocket, showcasing ISRO’s continued excellence in space exploration.

XPoSat Overview

XPoSat is ISRO’s inaugural satellite focused on X-ray polarisation studies and is equipped with two primary instruments – POLIX and XSPECT. The Raman Research Institute developed POLIX, while XSPECT was created by the U R Rao Satellite Centre in Bengaluru. These instruments will facilitate the measurement of X-ray polarisation and enable long-term observations of various cosmic sources.

Mission Objectives

The satellite is projected to operate for five years, and will investigate around 50 cosmic sources within the energy range of 8-30 keV. This mission will provide valuable data on the polarisation of X-rays, offering vital information about the behaviour of extreme astrophysical phenomena.

Launch Vehicle Details

The Polar Satellite Launch Vehicle (PSLV) has a proven track record, having been instrumental in missions such as Chandrayaan-1 and the Mars Orbiter Mission. For this launch, ISRO executed a unique manoeuvre by firing the rocket’s fourth stage twice. This action reduced the altitude from 650 km to 350 km, demonstrating advanced operational capabilities.

Additional Payloads

The PSLV Orbital Experimental Module-3 (POEM) hosted ten additional payloads during this mission. These included the Radiation Shielding Experiment Module, a Women-Engineered Satellite, and an amateur radio satellite called BeliefSat. The Green Impulse Transmitter was also part of this diverse payload group, denoting ISRO’s commitment to innovation.

This launch exemplifies ISRO’s dedication to advancing space research. It puts stress on the organisation’s focus on encouraging technological innovation and enhancing our understanding of the universe through satellite missions.
