In a resounding achievement, the Indian Space Research Organisation (ISRO) launched its proven Polar Satellite Launch Vehicle (PSLV) on Sunday, carrying seven Singaporean satellites from the Satish Dhawan Space Centre. The primary satellite and six co-passenger satellites were successfully deployed into their intended orbits, marking another milestone in India's space exploration endeavours. Additionally, ISRO scientists conducted a unique scientific experiment, effectively reducing space debris and promoting sustainable space use.
Successful Deployment of Singaporean Satellites
Approximately 23 minutes after liftoff, the primary satellite (DS-SAR) separated from the PSLV-C56, followed by the deployment of six co-passenger satellites into their respective orbits. The flawless execution of this mission reaffirms ISRO's reputation as a reliable and competent player in the global space arena. The launch took place from the first launch pad at the Satish Dhawan Space Centre, emitting thick fumes as the rocket majestically ascended into space.
ISRO's Commercial Arm's Role
The PSLV-C56 mission was undertaken by NewSpace India Limited (NSIL), ISRO's commercial arm responsible for commercial satellite launches. The successful deployment of the Singaporean satellites marks another achievement for NSIL, showcasing India's expertise in the commercial space launch market.
Scientific Experiment to Reduce Space Debris
During this mission, ISRO scientists conducted a groundbreaking experiment to mitigate the problem of space debris. After placing the customer satellites at an altitude of 536 km, the fourth stage of the PSLV rocket was deliberately lowered into a 300-kilometre orbit. This unique experiment aims to minimize the time the rocket spends in space as space debris after its mission concludes.
ISRO's innovative approach effectively reduces the time the fourth stage of the PSLV rocket remains in orbit as space debris from decades to less than two months. By bringing back the PS4 stage to a lower orbit of 300 km after its mission, ISRO has demonstrated its commitment to sustainable space use and reduced space debris. The agency's efforts align with global initiatives to maintain space sustainability and ensure the long-term viability of space missions.
Praises from ISRO Officials
ISRO Chairman S Somanath lauded the successful mission and congratulated the customers sponsored by the Government of Singapore for placing their trust in ISRO's capabilities. He expressed gratitude for the perfect orbits achieved and thanked all those involved in the mission.
D Radhakrishnan, Chairman and Managing Director of NewSpace India Limited, expressed his heartiest congratulations to the ISRO team for executing a marvellous and precise mission, meeting the customer's expectations beyond measure.
The successful launch of seven Singaporean satellites into their intended orbits further cements ISRO's position as a prominent player in the global space community. The groundbreaking experiment to reduce space debris showcases India's commitment to sustainable space exploration. As ISRO continues to make strides in space technology, it remains at the forefront of scientific innovation and international collaboration, pushing the boundaries of space exploration for the benefit of all humankind.
