With reference to India's X-ray Polarimeter Satellite (XPoSat) mission launched by ISRO, consider the following statements:

1. It is India's first dedicated scientific observatory to study the polarization of cosmic X-ray sources.
2. The spacecraft was launched into a Geostationary Transfer Orbit (GTO) using the Launch Vehicle Mark-3 (LVM3).
3. It carries two primary scientific payloads named POLIX and XSPECT.

Which of the statements given above are correct?

  1. A
    1 and 2 only
  2. 1 and 3 onlyCevap
  3. C
    2 and 3 only
  4. D
    1, 2 and 3

Cevap

Statements 1 and 3 are correct.
The statement identifying XPoSat as India's first dedicated X-ray polarimetry observatory is accurate. Furthermore, the statement listing POLIX and XSPECT as its two onboard scientific payloads is also accurate. The statement claiming a GTO insertion via LVM3 is wrong because the satellite was launched into a 650 km650\text{ km} Low Earth Orbit by PSLV-C58.

Adım Adım Çözüm

1
Evaluate Statement 1 regarding the primary scientific nature of XPoSat.
Statement 1 is correct. XPoSat is India's groundbreaking space observatory aimed at studying polarimetry of intense X-ray sources like neutron stars and black holes.
It is the world's second dedicated X-ray polarimetry space mission after NASA's IXPE.
2
Evaluate Statement 2 regarding the launch vehicle and target orbit.
Statement 2 is incorrect. XPoSat was launched by PSLV-C58 into a circular Low Earth Orbit (LEO) at an altitude of around 650 km650\text{ km} at a low inclination of 66^\circ, not into GTO by LVM3.
LEO provides optimal conditions for low-background X-ray observations and payload operation.
3
Evaluate Statement 3 regarding scientific instruments.
Statement 3 is correct. The mission carries POLIX (Polarimeter Instrument in X-rays) developed by Raman Research Institute and XSPECT (X-ray Spectroscopy and Timing) developed by UR Rao Satellite Centre.
These instruments measure polarimetric parameters and spectral characteristics simultaneously.
