ISRO XPoSat: India Launches Polarimetry Satellite to Unravel Black Hole Mystery

Sputnik correspondent
On New Year's Day, the Indian Space Research Organisation (ISRO) launched its X-ray Polarimeter (XPoSat) at 9:10 am from the Satish Dhawan Space Centre in Sriharikota, Andhra Pradesh.
The ISRO on Monday launched its
first X-ray Polarimeter Satellite (XpoSat), a space-based observatory to study X-ray polarisation and its
cosmic sources — celestial bodies such as
black holes, neutron stars, and magnetars.
At 9.32 am (IST), the ISRO announced that the lift-off of the Polar Satellite Launch Vehicle (PSLV) was normal, and XPoSAT was launched successfully.
"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 (earlier known as Twitter).
XPoSat carries two payloads -- POLIX (Polarimeter Instrument in X-rays) and XSPECT (X-ray Spectroscopy and Timing). It will carry out
long-term spectral and temporal studies of cosmic X-ray sources. It will also carry out polarisation and spectroscopic measurements of X-ray emissions from cosmic sources with the
POLIX and XSPECT payloads.ISRO chief S Somanath announced the successful launch. POEM refers to the PSLV Orbital Experimental Module.
"Only in 12 months (in 2024), we have to have a minimum of 12 missions on our target. It may exceed depending upon our ability to produce hardware and complete the testings. If it is not going to go well, there could be an impact. Otherwise, we are getting ready for at least 12-14 missions", Somanath said while speaking with media.
India XPoSat Vs. NASA's IXPE: Which Is Better
With this launch, India became the second nation after the United States (in 2021) to send a specialised astronomy observatory to study black holes and neutron stars.
India's XPoSat's cost ($30 million) is
six times less than NASA's IXPE ($188 million), and XPoSat is
expected to last for five years. However, IXPE's scheduled mission life is only two years.
