NEW DELHI: The study of space extends far beyond the sun and the moon—ISRO is poised for a groundbreaking milestone with the upcoming launch of the country's inaugural polarimetry mission. Set to take off by December 28, according to senior scientists at the Indian Space Research Organisation (ISRO), this mission marks a significant stride forward. Named the X-ray Polarimeter Satellite (EXPOSAT), its primary mission is to identify space-based X-ray sources. Distinguished as India's maiden endeavor and the world's second initiative dedicated to gauging light polarization in space, EXPOSAT will engage in extensive research. Its focus encompasses comprehensive studies involving imaging, time-domain investigations, and spectroscopy. Polarimetry stands as a pivotal tool empowering astronomers to glean insights about celestial bodies, ranging from transient comets to far-flung galaxies. Esteemed sources highlight the profound importance of this mission, emphasizing its critical role for the nation. ISRO's primary aim involves the detection and subsequent in-depth analysis of emissions from diverse astronomical sources while quantifying their strength. Notably, the mission will delve into the intricate exploration of challenging-to-study entities such as neutron stars, active galactic nuclei, and pulsar wind nebulae.
