Sriharikota (Andhra Pradesh): Indian Space Research Organisation (ISRO) Monday January 01, 2024 celebrated the beginning of the 2024 New Year launching XPoSat or the X-ray Polarimeter Satellite from SDSC-SHAR launch pad in Sriharikota, Andhra Pradesh.
“2024 lifted off majestically. XPoSat health is normal. Power generation has commenced”, ISRO announced on social media platform X at 09:57 am Monday January 01, 2024.
The XpoSat liftoff was at 09:32 am today.
"PSLV-C58 vehicle placed the satellite precisely into the intended orbit of 650 km with 6-degree inclination. The POEM-3 is being scripted," ISRO posted in X.
XPoSat (X-ray Polarimeter Satellite) is India’s first dedicated polarimetry mission to study various dynamics of bright astronomical X-ray sources in extreme conditions, according to ISRO.
The spacecraft carries two scientific payloads in a low earth orbit. The primary payload POLIX (Polarimeter Instrument in X-rays) has been designed to measure the polarimetry parameters (degree and angle of polarization) in 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.
A black hole, believed to be among the oldest mysteries of our solar system, is a region of spacetime where gravity is so strong that nothing, including light and other electromagnetic waves, has enough energy to escape it.
The XPoSat mission aims to conduct long-term studies to find out the structure and geometry of the cosmic X-ray sources, develop an understanding of galactic black hole binary sources, and study and confirm the production of X-rays.
ISRO XpoSat Mission to study black holes is second after US space agency NASA. NASA IXPE is on mission to study black holes since 2021.
The ISRO's XpoSat launch Monday also marked the 60th flight of the Polar Satellite Launch Vehicle (PSLV).
Polar Satellite Launch Vehicle (PSLV), a third generation launch vehicle of India, is the first Indian launch vehicle to be equipped with liquid stages. After its first successful launch in October 1994, PSLV emerged as a reliable and versatile workhorse launch vehicle of India.
