India, Aug. 13 -- The Indian Space Research Organisation (ISRO) has successfully conducted a ground static test of an improved version of the solid booster stage (SS1) of its Small Satellite Launch Vehicle (SSLV).

The test was carried out on 11 August 2026 at the static test facility at the Satish Dhawan Space Centre in Sriharikota.

The improved SS1 incorporates several design and process changes aimed at enhancing performance, simplifying production and reducing mass. These include an increased propellant burn rate in two motor segments, an optimised thermal protection system and process improvements in the nozzle subsystem to make it more suitable for production. The modifications have also resulted in a reduction in the overall mass...
