ISRO’s XPoSat Launch 2024: A New Year’s Leap in Space Exploration

    On January 1, 2024, the Indian Space Research Organisation (ISRO) marked the beginning of the year with the successful launch of its first X-ray Polarimeter Satellite (XpoSat). The launch was carried out from the Satish Dhawan Space Centre (SDSC) SHAR, Sriharikota.

    XPoSat is the first dedicated scientific satellite from ISRO designed to carry out research in space-based polarisation measurements of X-ray emission from celestial sources.

    The satellite was deployed into an eastward low-inclination orbit. The mission aims to study the dynamics of bright astronomical X-ray sources in extreme conditions.

    The satellite carries two payloads: POLIX (Polarimeter Instrument in X-rays) and XSPECT (X-ray Spectroscopy and Timing). Raman Research Institute has developed POLIX and XSPECT through Space Astronomy Group of URSC, Bengaluru.

    Prime Minister Narendra Modi hailed ISRO’s successful launch of its maiden X-Ray Polarimeter Satellite. In his tweet, he stated that the launch would enhance India’s prowess in the space sector. He congratulated ISRO on the successful launch of the X-ray Polarimeter Satellite (XPoSAT) mission on New Year’s Day.

    The successful launch of XPoSat marks a significant achievement in India’s space exploration journey. It not only enhances India’s prowess in the space sector but also paves the way for future scientific research in X-ray astronomy.

    The XpoSat mission was launched using a Polar Satellite Launch Vehicle (PSLV) on January 1, 20241. The satellite lifted off at 9:10 am, marking a significant milestone in India’s space exploration journey.

    The XpoSat is India’s first dedicated polarimetry mission. It aims to study the 50 brightest known astronomical sources in extreme conditions, including black hole X-ray binaries, non-thermal supernova remnants, neutron stars, active galactic nuclei, and pulsars. The satellite was placed in a circular low Earth orbit of 500–700 km, with a mission lifespan of at least five years.

    The polarimetric observations along with spectroscopic measurements are expected to break the degeneracy of various theoretical models of astronomical emission processes. This would be a major direction of research from XPoSat by the Indian science community.

    In addition to the XPoSat, the PSLV also launched 10 other payloads. These payloads were developed by start-ups, educational institutions, and ISRO centers.

    They include the following:

    • Radiation Shielding Experimental Module (RSEM) by TakeMe2Space
    • Women Engineered Satellite (WESAT) by LBS Institute of Technology for Women
    • BeliefSa-t0 Amateur radio satellite by K.J. Somaiya Institute of Technology
