GRIEVANCES & PENSIONS AND IN THE PRIME MINISTER’S OFFICE
(DR. JITENDRA SINGH):
****
(a) The major accomplishments under the Gaganyaan programme in the past year include
the following: IADT-01 successfully demonstrated the objective of end-to-end performance
validation of the critical parachute-based deceleration system of the Crew
Module for Gaganyaan mission in nominal mission scenarios.
For TV-D2 mission, electrical and mechanical integration activities of Crew
Module completed. Environmental tests completed.
Standalone checks of integrated Crew Module and Service Module completed
for G1. Integrated software simulations being carried out.
Service Module Propulsion System hot test for 350s to validate the integrated
performance for off-nominal mission profile.
Parachute systems: As part of the Rail Track Rocket Sled test, clustered
deployment of drogue parachutes under extreme conditions of dynamic
pressures carried out.
Integrated Main Parachute Airdrop Test conducted to demonstrate the delay in
disreefing between the two main parachutes.
Ground Qualification Tests of Crew Escape System motors, Orbital Module
Adaptor, Service Module structure, Service Module Fairing, separation systems
and pyros carried out.
(b) & (c)
1st Test vehicle mission and 1st Integrated Airdrop tests were successful and met all the
test objectives. Based on the technical observations, certain improvements such as crew
module uprighting systems, additional checks during parachute assembly, have been
incorporated.
(d) The cumulative expenditure as on January 2026 is ~ ₹6018 Crores
(e) Risk mitigation in the actual flight is carried out by conducting extensive ground tests
simulating various failure scenario. For instance, in the recent integrated Main
Parachute Airdrop Test, one drogue and one main parachute failure case was simulated
and system performance was verified successfully.
(f) In October 2024, the scope of Gaganyaan programme was revised from three missions
(G1, G2, H1) to eight missions. It includes three uncrewed missions G1, G2, G3
followed by two crewed missions (H1 & H2) followed by docking mission to any space
station (G4), launch of BAS-01 and docking mission to BAS-01 (G5).
