The Indian Space Research Organisation (ISRO) plans to conduct a test of the in-flight abort system of the Gaganyaan crew capsule it is developing for future human space flights. Launch is scheduled for 02:30 UTC on 2023-10-21 from the Satish Dhawan Space Centre, Sriharikota, India.
The rocket, designated TV-D1, is a single stage vehicle derived from the liquid rocket boosters of the Geosynchronous Satellite Launch Vehicle (GSLV), equipped with avionics and control systems for autonomous flight.
At an altitude of 11.7 km and speed of 363 metres/second the crew module’s solid rocket escape system will fire to pull the capsule away from the booster rocket… The capsule will follow a ballistic trajectory upward to 16.6 km, where the escape system will be jettisoned. At an altitude of 2.4 km parachutes will deploy to allow a splashdown around 10 km from the launch site. The flight from liftoff to splashdown will take around nine minutes.
The crew module for this flight is a “boilerplate” capsule without crew accommodations, life support, or a heat shield.
