Consider the following statements regarding the X-ray Polarimeter Sate...
Explanation:
The X-ray Polarimeter Satellite (XPoSat) mission is an upcoming space mission that aims to study black hole binaries and low-magnetic field neutron stars. It is being developed by the Indian Space Research Organisation (ISRO), making the first statement correct. Let's delve into each statement in detail:
Statement 1: It is launched by the Indian Space Research Organisation (ISRO).
- The Indian Space Research Organisation (ISRO) is the premier space agency of India. It is responsible for all the space-related activities, including satellite launches and space missions.
- The XPoSat mission is indeed launched by ISRO. It is a collaborative effort between ISRO and various other institutions, including the Tata Institute of Fundamental Research (TIFR), Mumbai, and the Raman Research Institute (RRI), Bengaluru.
- Therefore, the first statement is correct.
Statement 2: It aims to study black hole binaries and low-magnetic field neutron stars.
- The primary objective of the XPoSat mission is to study the polarization of X-rays emitted from celestial sources, particularly black hole binaries and low-magnetic field neutron stars.
- Black hole binaries are systems where a black hole and a companion star are in close orbit around each other. By studying the X-ray polarization from these binaries, scientists can gain insights into the geometry and physical processes occurring near the black hole.
- Neutron stars are dense remnants of massive stars that have undergone a supernova explosion. Some neutron stars have low magnetic fields, and studying the polarization of X-rays emitted from these stars can provide valuable information about their structure and magnetic field properties.
- Hence, the second statement is also correct.
Therefore, both statements 1 and 2 are correct. The X-ray Polarimeter Satellite (XPoSat) mission is indeed launched by the Indian Space Research Organisation (ISRO), and it aims to study black hole binaries and low-magnetic field neutron stars.

Consider the following statements regarding the X-ray Polarimeter Sate...
Recently, the Indian Space Research Organisation (ISRO) launched the PSLV-C58 X-ray Polarimeter Satellite (XPoSat) mission.
- It is the first dedicated scientific satellite from ISRO to carry out research in space-polarisation measurements of X-ray emission from celestial sources.
- It carries two payloads namely
- POLIX: It is an X-ray Polarimeter for astronomical observations in the energy band of 8-30 keV.
- The payload is being developed by Raman Research Institute (RRI), Bangalore in collaboration with U R Rao Satellite Centre (URSC).
- It is expected to observer about 40 bright astronomical sources of different categories during the planned lifetime of XPoSat mission of about 5 years.
- This is the first payload in the medium X-ray energy band dedicated for polarimetry measurements.
- XSPECT: It is an X-ray SPECtroscopy and Timing payload onboard XPoSat, which can provide fast timing and good spectroscopic resolution in soft X-rays.
- It can provide long-term monitoring of spectral state changes in continuum emission, changes in their line flux and profile, simultaneous long term temporal monitoring of soft X-ray emission in the X-ray energy range 0.8-15 keV.
- It would observe several types of sources viz X-ray pulsars, blackhole binaries, low-magnetic field neutron star (NS) in LMXBs, AGNs and Magnetars.
- The launch put India in an elite category as it has become the second (after NASA’s Imaging X-ray Polarimetry Explorer (IXPE) launched in 2021) nation to send an observatory to study astronomical sources such as black holes, neutron stars among others
Hence both statements are correct.
