ISRO’s Successful Launch PSLV-C56 Rocket with DS-SAR Satellite and Co-Passenger Payloads

The Indian Space Research Organisation (ISRO) ‘s  PSLV-C56 rocket successfully launched the Singapore’s DS-SAR satellite and six co-passenger payloads from the first launch-pad of SDSC-SHAR in Sriharikota on 30 June 2023.

  1. PSLV-C56 is a Dedicated Commercial Mission of NewSpace India Limited (NSIL) for ST Engineering, Singapore. DS-SAR is a Radar Imaging Earth Observation satellite and the primary payload for the mission.
  2. The mission also carried six co-passenger customer satellites from Singapore.
  3. Among the co-passenger payloads, VELOX-AM is a microsatellite developed by Nanyang Technological University (NTU), Singapore, for technology demonstration of Additive Manufacturing (AM) payloads.
  4. ARCADE is a 27U microsatellite designed and built by Nanyang Technological University (NTU), Singapore, in collaboration with the INSPIRE consortium. ARCADE carries an iodine-based solid propellant propulsion module for orbit maintenance.
  5. The DS-SAR satellite is equipped with a Synthetic Aperture Radar (SAR) payload developed by Israel Aerospace Industries (IAI).
  6. The SAR payload enables DS-SAR to provide high-quality imagery regardless of weather conditions, offering all-weather day and night coverage with 1m-resolution imaging and full polarimetry.
  7. PSLV-C56 is configured in its core-alone mode, similar to the previous C55 mission. All satellites were injected into a 535 km circular orbit with 5 degrees orbital inclination.
  8. After injecting all the satellites, the upper stage of the rocket would be placed in a lower orbit of 300 km to ensure reduced orbital life and address space debris mitigation problems.
  9. This was the 58th flight of PSLV and the 17th flight of PSLV in Core Alone configuration.
  10. After the successful launch, ISRO Chairman S. Somnath congratulated the customers sponsored by the Government of Singapore for their mission on board PSLV.
  11. Mission Director Biju SR mentioned that it is the 56th successful mission of PSLV, which successfully injected all seven customer satellites into their designated orbits.
