ISRO Qualifies Improved SSLV First Stage, Boosting Payload Capability and Industrial Readiness
The improved first stage, known as SS1, incorporates a series of changes designed to increase launch performance while simultaneously reducing structural mass and simplifying manufacturing. According to ISRO’s assessment, the upgraded stage could provide approximately 100 kg of additional payload capability to Low Earth Orbit, a significant gain for a launch vehicle originally designed to place payloads of around 500 kg into LEO.
