  • India’s maiden human space flight ‘H1’ mission is targeted to be launched in the fourth quarter of 2024. 
  • In view of the paramount importance of crew safety, two test vehicle missions are planned before the ‘G1’ mission to demonstrate the performance of crew escape system and parachute-based deceleration system for different flight conditions.
  • The uncrewed ‘G1’ mission is targeted to be launched in the last quarter of 2023 followed by the second uncrewed ‘G2’ mission in the second quarter of 2024, before the final human space flight ‘H1’ mission in the fourth quarter of 2024.
  • The first uncrewed flight ‘G1’ mission is aimed at validating the performance of human-rated launch vehicle, orbital module propulsion system, mission management, communication system and recovery operations. The mission will carry a humanoid as payload.
