ISRO Successfully Tests SSLV Third Stage
The Indian Space Research Organisation has successfully conducted a ground test of the upgraded third stage of its Small Satellite Launch Vehicle. The static test was carried out at the Satish Dhawan Space Centre in Sriharikota as part of preparations for upcoming SSLV missions.
Key Upgrades in the Third Stage
The third stage, known as SS3, features major design improvements aimed at enhancing overall launch vehicle performance. ISRO said the upgraded stage uses a carbon-epoxy motor casing, which has significantly reduced the stage’s weight. This reduction is expected to increase the SSLV’s payload carrying capability. The stage has also been equipped with an improved igniter system and a redesigned nozzle to ensure better efficiency and reliability during flight.
Test Performance and Results
During the ground test, the SS3 motor was fired for its full duration under controlled conditions. More than 200 sensors were used to monitor critical parameters such as pressure, thrust, temperature and structural behaviour. ISRO said all recorded data closely matched pre-test predictions, confirming the robustness of the upgraded design and validating the performance of key subsystems.
Importance for Future SSLV Missions
With this successful test, the upgraded third stage has been cleared for use in future SSLV launches. The SSLV programme is designed to support quick, cost-effective launches of small satellites and offer rapid mission turnaround. ISRO said the test marks an important milestone in strengthening India’s capabilities in the growing global small satellite launch market.
