The Indian Space Research Organisation (ISRO) successfully launched the PSLV-C56 on July 30, 2023, from the Satish Dhawan Space Centre in Sriharikota. The launch vehicle carried seven foreign satellites, including the DS-SAR satellite from Singapore.

The Indian Space Research Organisation (ISRO) successfully launched the PSLV-C56 on July 30, 2023, from the Satish Dhawan Space Centre in Sriharikota. The launch vehicle carried seven foreign satellites, including the DS-SAR satellite from Singapore.

The DS-SAR satellite is a radar imaging earth observation satellite that will be used to provide all-weather, day-and-night imaging at 1-meter resolution. It is the first satellite from Singapore to be equipped with a SAR payload.

The other six satellites that were launched on PSLV-C56 are:

  • VELOX-I, a microsatellite from Singapore that will be used for remote sensing and communications
  • INS-2TD, a technology demonstrator satellite from India that will test new technologies for future satellites
  • GSAT-24, a communication satellite from India that will provide high-speed broadband services
  • CALET-2, a scientific satellite from Japan that will study cosmic rays
  • INSPIRE-1, a student satellite from the United States that will conduct experiments in space
  • NUSSAT-1, a student satellite from Singapore that will study the Earth's atmosphere

The PSLV-C56 launch was a success, and all seven satellites were placed in their intended orbits. This is the 58th flight of the PSLV and the 17th flight of the PSLV in Core Alone configuration.

The successful launch of PSLV-C56 is a testament to the continued success of the ISRO's space program. The launch also demonstrates the growing cooperation between India and other countries in the space sector.

The DS-SAR satellite is expected to be operational in the coming months, and it will provide valuable data for a variety of applications, including disaster management, agriculture, and environmental monitoring. The other six satellites on the PSLV-C56 mission are also expected to make significant contributions to their respective fields.

The successful launch of PSLV-C56 is a major milestone for the ISRO and for the global space community. It demonstrates the continued progress of India's space program and the growing importance of international cooperation in space.


The Indian Space Research Organisation (ISRO) successfully launched the PSLV-C56 on July 30, 2023, from the Satish Dhawan Space Centre in Sriharikota. The mission carried a primary satellite, the DS-SAR, along with six co-passenger satellites from Singapore.

The DS-SAR is a radar imaging earth observation satellite developed by the Defence Science and Technology Agency (DSTA) of Singapore and ST Engineering. It is equipped with a Synthetic Aperture Radar (SAR) payload that can provide all-weather, day and night imaging at a resolution of 1 meter. The satellite will be used for a variety of applications, including land mapping, maritime surveillance, and disaster management.

The six co-passenger satellites are:

  • STSAT-2D: A 150 kg Earth observation satellite developed by ST Engineering. It is equipped with a panchromatic and multispectral imager that can provide high-resolution imagery of the Earth's surface.
  • DeorbitSail-1: A 10 kg experimental satellite developed by the Indian Institute of Space Science and Technology (IIST). It is equipped with a deorbit sail that will be used to test the feasibility of using a sail to deorbit satellites at the end of their mission.
  • INS-2TD: A 375 kg technology demonstration satellite developed by the Indian National Space Agency (INSA). It is equipped with a variety of payloads, including a SAR payload, a multispectral imager, and a navigation payload.
  • INSPIRE-1: A 3.7 kg CubeSat developed by the Indian Institute of Technology Bombay (IIT Bombay). It is equipped with a payload that will be used to study the effects of space radiation on electronic devices.
  • RUAG-1: A 10 kg CubeSat developed by RUAG Space of Switzerland. It is equipped with a payload that will be used to study the Earth's atmosphere.
  • VELOX-II: A 10 kg CubeSat developed by the University of Toronto Institute for Aerospace Studies (UTIAS). It is equipped with a payload that will be used to study the Earth's magnetosphere.

The PSLV-C56 mission was a success, and all seven satellites were successfully placed into orbit. The mission is a further demonstration of ISRO's capabilities in launching satellites into orbit and will help to strengthen India's position as a leading spacefaring nation.

In addition to the successful launch of the PSLV-C56 mission, ISRO also announced that it is planning to launch a new satellite, the GSAT-31, in the coming weeks. The GSAT-31 is a communication satellite that will be used to provide telecommunications services to India and neighboring countries. The satellite is expected to be launched from the Satish Dhawan Space Centre in Sriharikota.


Sure, I can write about the ISRO PSLV-C56 launch.

The Indian Space Research Organisation (ISRO) successfully launched the PSLV-C56 on July 30, 2023 from the Satish Dhawan Space Centre in Sriharikota. The launch vehicle carried seven foreign satellites, including the DS-SAR satellite of the Singapore Government.

The DS-SAR satellite is a radar imaging earth observation satellite that will be used to provide all-weather, day-and-night imagery of Singapore and its surroundings. The satellite is equipped with a Synthetic Aperture Radar (SAR) payload that can image at a resolution of 1 meter.

The other six satellites that were launched on the PSLV-C56 mission are:

  • STE-SAT1, a 360kg satellite developed by Singapore Technologies Engineering (ST Engineering)
  • SCOOB-1, a 110kg CubeSat developed by the University of Surrey
  • INS-1A, a 100kg CubeSat developed by the Indian Institute of Space Science and Technology (IIST)
  • INS-1B, a 100kg CubeSat developed by the IIST
  • NUSSat-1, a 100kg CubeSat developed by the National University of Singapore
  • NIUSAT-1, a 100kg CubeSat developed by the Nanyang Technological University, Singapore

The PSLV-C56 mission was a success, and all seven satellites were successfully placed into orbit. The launch of the DS-SAR satellite is a significant milestone for Singapore, as it will provide the country with its own independent source of high-resolution satellite imagery. The other six satellites that were launched on the mission will also be used for a variety of scientific and commercial applications.

The successful launch of the PSLV-C56 mission is a testament to the continued progress of the Indian space program. ISRO has a long history of successful launches, and the PSLV-C56 mission is just the latest example of their expertise. The launch of the DS-SAR satellite is also a sign of the growing cooperation between India and Singapore in the field of space.
