2 September, 2023 - PSLV-C57/Aditya-L1 Mission

1 January, 2024 - PSLV-C58/XPoSat Mission

22. Satellites TeLEOS-2 and Lumelite-4 were launched in April 23 from Sriharikota by the launcher: [Rajasthan P.C.S. (Pre) 2023]

Correct Answer: (c) PSLV-C55
Solution:

The PSLV C55 was the 57th mission of Indian Space Research Organisation's Polar Satellite Launch Vehicle (PSLV). PSLV-C55/TELEOS-2 was launched successfully on 22 April, 2023 from Satish Dhawan Space Centre (SDSC), SHAR, Sriharikota, Andhra Pradesh.

This was a dedicated commercial mission through NewSpace India Limited (NSIL) with TeLEOS-2 as primary satellite and Lumelite-4 as a co-passenger satellite. The satellites weigh about 741 kg and 16 kg, respectively. Both satellites belong to Singapore.

23. Consider the following statements about recently launched XPoSat (X-ray Polarimeter Satellite) by ISRO. [Chhattisgarh P.C.S. (Pre) 2023]

(1) It is India's first dedicated polarimetry mission to study various dynamics of bright astronomical X-ray sources in extreme conditions.

(2) The spacecraft will carry two scientific payloads in a low earth orbit.

Which of the statement/s given above is/are true?

Correct Answer: (c) Both (1) and (2)
Solution:

ISRO's PSLV-C58 has launched XPoSat Satellite on I January, 2024. 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. The spacecraft carried two scientific payloads in a low earth orbit.

The primary payload POLIX (Polarimeter Instrument in X-rays) will 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 0.8-1.5 keV
