Space Part-2

• 22 April, 2023: PSLV-C55/TeLEOS-2 Mission
• 30 July, 2023: PSLV-C56/DS-SAR Mission
• 2 September, 2023: PSLV-C57/Aditya-L1 Mission
• 1 January, 2024: PSLV-C58/XPoSat Mission

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 the primary satellite and Lumelite-4 as a co-passenger satellite. The satellites weighed about 741 kg and 16 kg, respectively. Both satellites were sent to Singapore.

ISRO's PSLV-C58 has launched XPoSat Satellite on 1 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 for X-rays) will measure the polarimetry parameters (degree and angle of polarization) in the medium X-ray energy range of 3-35 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.

Apple Satellite was launched on June 19, 1981 by Ariane launch vehicle from Kourou in French Guiana. It was India's First experimental geostationary communication satellite.

INSAT-1D was launched on June 12th, 1990. INSAT-1D was a multifunctional satellite that provides telephone, television, and weather observation service for India.

INSAT-2A was India's first indigenously built satellite. This satellite was launched on July 10th, 1992 from Kourou, French Guiana.

On July 10, 2006, the Geosynchronous Satellite Launch Vehicle (GSLV) carrying the INSAT-4C communication satellite veered off course and exploded 60 seconds after lift-off. It had a weight of 2168 kg and was developed by ISRO at a cost of Rs. 350 crore. At present, weighing about 5854 kg, GSAT-11 is the heaviest satellite built by ISRO. It was launched on December 5, 2018, from Kourou launch base, French Guiana by Ariane-5 VA-246.

ISRO's Polar Satellite Launch Vehicle PSLV-C22 successfully launched IRNSS-1A, the first satellite in the Indian Regional Navigation Satellite System (IRNSS) on July 1st, 2013 from Satish Dhawan Space Centre, Sriharikota.
