SS1 improved version undergoes ground static test
- The improved SS1 version underwent a ground static test on 11 August 2026 at Satish Dhawan Space Centre.
- The upgrade included an enhanced propellant burn rate in two motor segments, optimized thermal protection and reduced mass.
- More than 600 parameters were measured, and the result was close to predicted performance.
- ISRO's SSLV can carry about 100 kg to low Earth orbit and has had two successful development flights.
- Technology transfer to Indian industry is underway, and manufacturing in large numbers is expected.
What happened
SS1 underwent a ground static test of an improved version. The event is recorded for 2026-08-11 at Satish Dhawan Space Centre, Sriharikota.
What we know
The upgrade included an enhanced propellant burn rate in two motor segments, an optimized thermal protection system, process improvements in the nozzle sub-system and reduced mass.
During the test, more than 600 parameters were measured, and the result was close to predicted performance.
The design improvements were qualified.
The Small Satellite Launch Vehicle (SSLV) was developed by ISRO and has a payload of about 100kg to Low Earth Orbit.
SSLV has had two successful development flights, transfer of technology to Indian industry is underway, and it is expected to be manufactured in large numbers.
Why it matters
For readers tracking the lunar industry, the report is relevant as launch-industry infrastructure: the facts describe an ISRO small satellite launcher, its payload capability, its two successful development flights, ongoing technology transfer to Indian industry and expected manufacturing in large numbers.
