ISRO Tests Improved Version of Small Satellite Launch Vehicle
India's space agency, ISRO, has a rocket called the Small Satellite Launch Vehicle, or SSLV, that is made to launch small satellites.
They just tested a better version of the rocket's first stage booster, which is the powerful part that helps the rocket lift off.
The test happened on a special testing stand at a space centre in Sriharikota.
The new booster burns its fuel a little faster, has better heat protection, and weighs less than before.
Many sensors watched the test and checked over 600 different things about how the booster performed.
The booster worked almost exactly the way scientists predicted it would.
Because the booster is better, the rocket will be able to carry about 100 more kilograms of cargo into space.
The SSLV has already completed two successful test flights.
Soon, Indian companies will help build many of these rockets so that small satellites can be launched easily and quickly.
ISRO successfully conducted the ground static test of an improved SS1 solid booster stage of the Small Satellite Launch Vehicle (SSLV) on August 11, 2026.
The test was held at the static test facility at the Satish Dhawan Space Centre, Sriharikota.
Design improvements include enhanced propellant burn rate in two motor segments, an optimised thermal protection system, nozzle sub-system process improvements, and a reduction in mass.
Extensive instrumentation measured more than 600 parameters, and the motor's performance was close to the predicted performance.
The improved SS1 version is expected to enhance SSLV's payload capability by about 100kg to Low Earth Orbit.
