Background
In April 2022 it was proposed that both demonstrations missions should have a depressurized crew module.[2] On 10 August 2022 ISRO performed a successful static test from the Crew Escape System.[3] The crew module fairing and the high altitude abort engine was delivered by Hindustan Aeronautics Limited on 18 August 2022.[4] In December 2022, structural qualification test for Crew Module Fairing with Grid Fins was successfully completed for TV-D1 configuration.[5]
Mission objectives
With a rocket based upon the GLSV L40 stage,[6] TV-D1, the first development flight from the Gaganyaan program,[4] will be launched up until 11 km from sea level, where an in-flight abort scenario will be initiated, and the capsule should flight until 15–16 km. The mission should test the separation from the rocket and its trajectory until a safe distance and parachute deployment.[7][4] The capsule will have the same mass as the crewed version.[8]
The mission will be tracked by the team at Sriharikota.[7][4] If successful, India will be the fourth country, after Russia, United States and China, to master this technology.[9]
Gaganyaan 1, the first orbital test flight, is planned to 2023.[10]
