ISRO’s SOLVE test for Gaganyaan: parachute validation, crew module landing and 10-chute descent system
ISRO conducted a ground test of the SOLVE solid motor on 3 July 2026 to validate Gaganyaan’s parachute-based deceleration system.
Key highlights
Direct fact
On July 3, 2026, ISRO successfully conducted the ground test of the Sub-Orbital Launch Vehicle for Experiments (SOLVE) solid motor at the Static Test Facility, Satish Dhawan Space Centre, Sriharikota, for the Gaganyaan mission.
Key specifics
- SOLVE is a solid-motor-based test platform for Integrated Parachute Tests of Gaganyaan’s Crew Module.
- The SOLVE solid stage is derived from the PSLV strap-on motor, with modifications for Gaganyaan test needs.
- ISRO said the Crew Module would be carried to an altitude of 10–17 km and then separated from the vehicle.
- The Gaganyaan descent system uses 10 parachutes of 4 types to reduce touchdown velocity before sea splashdown.
- The mission is envisaged to carry a crew of 3 members to low Earth orbit and return them safely to Indian sea waters.
Exam lens
Question type: Space technology, mission sequence, launch vehicle components. Key facts: July 3, 2026, SOLVE, Satish Dhawan Space Centre, Sriharikota, 10–17 km altitude, 10 parachutes, 3-member crew. TNPSC may ask the role of SOLVE in validating Gaganyaan’s deceleration and crew escape systems.
