All HLVM3 propulsion stages and structures for Gaganyaan are ground-tested and complete; the Crew Escape System's 5 motor types are developed and static-tested
The uncrewed TV-D1 test flight already validated the Crew Escape System; two Integrated Air Drop Tests (IADT-01, IADT-02) validated the deceleration system; the G1 uncrewed orbital mission, carrying the robot Vyommitra, is in advanced preparation
Gaganyatris have completed generic training in Russia and are now in mission-specific training at the Astronaut Training Facility, Bengaluru
TV-D1 — successful in-flight validation of the Crew Escape System
IADT-01 — first Integrated Air Drop Test of the Crew Module deceleration system
IADT-02 — second Integrated Air Drop Test, also successful
TV-D2 — second Test Vehicle Demonstration mission
G1 — first uncrewed orbital Gaganyaan mission, carrying the humanoid robot Vyommitra
ECLSS is the 'system of systems' that keeps the Gaganyaan Crew Module habitable — maintaining temperature, humidity, pressure and carbon dioxide levels — developed indigenously by ISRO. Its engineering model has been realised, and a reduced-version flight demonstration is planned on the uncrewed missions before any crewed flight is attempted.
Simple Analogy: An aircraft cabin's life-support system, but fully self-contained and space-rated.
ISRO's nodal centre coordinating the Gaganyaan programme end-to-end — mission planning, crew systems, training
Half-humanoid robot that will fly on the G1 uncrewed mission to simulate astronaut conditions and validate ECLSS and other life-support systems ahead of a crewed flight
The human-rated version of ISRO's LVM3 (formerly GSLV Mk III) launch vehicle, 43.43 m tall, using twin Vikas engines on its core liquid stage and a cryogenic upper stage
