Objectives of the XPOSAT Mission
The main objective of the XPOSAT mission is to research cosmic X-ray sources in unprecedented detail. Scientists hope to solve puzzles about black holes, neutron stars, and other high-energy events in the cosmos by examining the polarization of X-rays emitted by celestial objects.
1. Studying Cosmic X-ray Sources:
XpoSat seeks to study and analyze cosmic X-ray sources such as black holes, neutron stars, and active galactic nuclei. Scientists want to better understand the nature, behaviour, and impact of X-rays released by these sources by detecting and analyzing them.
2. Mapping Galactic Structure:
The satellite can map the structure and distribution of galaxies, clusters, and other cosmic formations. This data will help us understand the universe's large-scale structure, development, and the dynamics of its celestial bodies.
3. Investigating Transient Phenomena:
XpoSat intends to identify and study transitory phenomena like gamma-ray bursts, supernovae, and other high-energy events across the cosmos. Scientists investigate these occurrences to understand the mechanics underlying these intense outbursts and their consequences for astrophysics.
XPOSAT Satellite Overview
Design and Specifications
The XPOSAT satellite is equipped with cutting-edge instrumentation and technology, allowing it to catch and analyze X-ray emissions with unprecedented precision. Its small design and effective power management mechanisms assure peak performance throughout its mission life.
Payload Instruments
The spacecraft is equipped with several modern payload equipments, including X-ray telescopes and polarimeters, which are intended to catch and study X-ray radiation from diverse cosmic sources. The primary payload POLIX (Polarimeter Instrument in X-rays) will measure the polarimetry parameters (degree and angle of polarization) in a 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. These tools allow scientists to investigate the polarization characteristics of X-rays, giving crucial information on the nature and behaviour of celestial objects.
