ISRO Gaganyaan Clears Crew Escape System Abort Test
The TV-D2 test fired its abort motors at maximum aerodynamic pressure and recovered the crew module in the Bay of Bengal.
The Indian Space Research Organisation (ISRO) recorded a decisive success in its human spaceflight programme when the TV-D2 abort test vehicle lifted off from Sriharikota and replicated the failure conditions a crewed Gaganyaan capsule might face at maximum aerodynamic pressure.
The Crew Escape System (CES) fired its solid-propellant abort motors with textbook precision, separating the crew module from the simulated faulty launch vehicle before parachutes brought it down within the designated Bay of Bengal recovery zone.
Key Highlights
- TV-D2 tested the Crew Escape System at maximum aerodynamic pressure.
- Abort motors separated the crew module and parachutes deployed on cue.
- Capsule recovered intact by an Indian Navy vessel.
- CES now validated at two critical flight-envelope points.
- First uncrewed orbital flight targeted for Q3 of the coming year.
Why the Crew Escape System Matters
The CES is the most safety-critical subsystem of any crewed spacecraft. If a launch vehicle fails between liftoff and orbit, the system must fire within milliseconds, overcome the vehicle's thrust and pull the crew module clear of the danger zone. TV-D2 replicated a worst-case high-dynamic-pressure scenario, where aerodynamic and structural loads are at their peak.
ISRO Chairman S. Somanath confirmed all abort-motor parameters were nominal and the capsule was recovered structurally intact. “The CES has now been validated at two critical flight envelope points,” he said.
The test at a glance
| Detail | Fact |
|---|---|
| Launch site | Sriharikota |
| Test | Abort at maximum aerodynamic pressure |
| Landing accuracy | Within 200 m of target point |
| Recovery | Indian Navy, Bay of Bengal |
| Next step | Uncrewed orbital flight, Q3 next year |
Road to the Crewed Mission
India's astronaut corps — four Air Force pilots trained in Russia and India — will fly the crewed LVM3 mission once three uncrewed test flights succeed. That would make India only the fourth country to independently place humans in orbit.
Built In-House
The crew module, service module and escape system were designed entirely by ISRO engineers, with the solid abort motors and parachute recovery system validated in this series. The parachutes deployed at the correct altitude, and the capsule landed within 200 metres of the projected point. ISRO's hardware-validation-first approach complements India's wider deep-tech push, from medical AI to semiconductor design.
