Overview
- ISRO announced on Sunday that it completed three system-level qualification tests that targeted splashdown uprighting, crew‑module–service‑module umbilical separation and the apex‑cover jettison load case.
- A float‑inflation test of the Crew Module Uprighting System used stored cold gas from high‑pressure bottles and showed the flotation elements inflated within required timing and pressure ranges to flip an inverted capsule upright.
- A separation trial for the CSU‑2 umbilical demonstrated a clean disconnect from a simulated crew module and confirmed the structural stability of the attached crew‑module panel and its interfaces.
- Engineers applied roughly 1.75 times the estimated apex‑cover separation loads to an instrumented mockup and recorded strains and deformations that stayed within design margins to validate the parachute‑cover jettison sequence.
- These ground tests reduce specific technical risks for crew safety but do not by themselves allow a crewed flight because further subsystem integration, additional qualifications and uncrewed flight demonstrations remain needed before astronauts fly.
