Recently, the Indian Space Research Organisation (ISRO) announced that the launch of the PSLV-C56 carrying Singapore’s DS-SAR satellite will take place on July 30.

About PSLV-C56: 


  • The PSLV-C56 carrying DS-SAR satellite along with six co-passengers will be launched from the Satish Dhawan Space Centre in Sriharikota.
  • It is configured in its core-alone mode, similar to that of C55.
  • It would launch DS-SAR, a 360 kg satellite into a Near-equatorial Orbit (NEO) at 5 degrees inclination and 535 km altitude.
  • What is The DS-SAR satellite?
    • It is developed under a partnership between DSTA (representing the Government of Singapore) and ST Engineering.
    • It will be used to support the satellite imagery requirements of various agencies within the Government of Singapore.
    • ST Engineering will use it for multi-modal and higher responsiveness imagery and geospatial services for their commercial customers.
    • It carries a Synthetic Aperture Radar (SAR) payload developed by Israel Aerospace Industries (IAI).
    • This allows the DS-SAR to provide for all-weather day and night coverage and is capable of imaging at 1m resolution at full polarimetry.      
  • Along with DS-SAR, the PSLV-C56 will carry
    • VELOX-AM: A 23 kg technology demonstration microsatellite.
    • ARCADE : Atmospheric Coupling and Dynamics Explorer (ARCADE), an experimental satellite.
    • SCOOB-II: A 3U Nanosatellite flying a technology demonstrator payload;
    • NuLIoN : An advanced 3U Nanosatellite enabling seamless IoT connectivity in both urban and remote locations;
    • Galassia-2: A 3U Nanosatellite that will be orbiting at low earth orbit.
    • ORB-12 STRIDER: Satellite is developed under an International collaboration.


Q1) What is  PSLV?

PSLV stands for Polar Satellite Launch Vehicle. It is an expendable launch vehicle developed and operated by the Indian Space Research Organisation (ISRO), the space agency of the Government of India. PSLV is primarily used to launch satellites into various orbits, including polar, geosynchronous transfer, and sun-synchronous orbits.
