The Indian Space Research Organisation (ISRO) has successfully fired the improved third stage of its Small Satellite Launch Vehicle (SSLV) at the Sriharikota spaceport. This latest test marks another important step in strengthening India’s small satellite launch capabilities and increasing reliability for future space missions.
According to ISRO officials, the test was conducted at the Satish Dhawan Space Centre, where the upgraded stage performed “as expected” under all test conditions. The firing lasted for about 90 seconds. Engineers closely monitored pressure, temperature, and performance parameters to validate the enhanced design.
The SSLV, designed to carry payloads of up to 500 kilograms to low-Earth orbit, provides a low-cost solution for launching small satellites. It addresses the growing global demand for quick and affordable launches, especially from academic institutions and small private companies.
Earlier, ISRO had faced minor challenges in SSLV’s debut flight in August 2022 when the rocket failed to place satellites in their intended orbit. However, subsequent missions improved performance through design corrections. The new third-stage enhancement focuses on better propulsion efficiency, structural stability, and minimal vibration for smoother payload deployment.
ISRO plans to integrate the improved stage into upcoming SSLV missions scheduled for 2026. This successful test strengthens India’s position in the global small satellite market and supports the country’s goal of boosting commercial space operations through its space public sector arm, NewSpace India Limited (NSIL).
