ISRO Completes Crew Module-Service Module Separation Tests for Gaganyaan at VSSC
ISRO has completed a series of Crew Module-Service Module (CM-SM) separation tests at the Vikram Sarabhai Space Centre, Thiruvananthapuram, on a rig that simulated the full CM-SM assembly with extensive instrumentation. The sequence validated pyrotechnic devices and jettisoning systems that sever several umbilical connections, and checked shock survivability of avionics, the Inertial Navigation Systems, the Aft and Conical Heat Shield, the CM Deployable Umbilical Shield and the Uprighting System. It clears a key gate before the first uncrewed mission Gaganyaan-1 (G1), which will carry the half-humanoid robot Vyommitra, and follows the crew-module qualification and air-drop tests completed earlier in 2026.
