Gaganyaan mission Live Updates: ISRO chief gives mission details
Gaganyaan mission Live Updates: ISRO chairman S. Somanath said,“I'm very happy to announce the successful accomplishment of the TV-D1 mission. The purpose of the mission was to demonstrate the Crew Escape System (CES) for the Gaganyaan program through a test vehicle demonstration in which the vehicle has gone slightly above the Mach number that is the speed of sound. The CES took the crew module away from the vehicle and the subsequent operations by the crew, parachutes opening, and touchdown in the sea at the required velocity has been very well accomplished. We have received confirmation of data on all of this”.

Gaganyaan mission Live Updates: What is the Orbital Module associated with the Gaganyaan mission?
Gaganyaan mission Live Updates: The Orbital Module (OM) that will be Orbiting Earth comprises of Crew Module (CM) and Service Module (SM). OM is equipped with state-of-the-art avionics systems with adequate redundancy considering human safety.
CM is the habitable space with an Earth-like environment in space for the crew. It is of double-walled construction consisting of a pressurized metallic Inner Structure and an unpressurized External Structure with a Thermal Protection System (TPS). It houses crew interfaces, human-centric products, life support systems, avionics, and deceleration systems. It is also designed for re-entry to ensure the safety of the crew during descent till touchdown.
SM will be used to provide necessary support to CM while in orbit. It is an unpressurized structure containing thermal system, propulsion system, power systems, avionics systems and deployment mechanisms.

Gaganyaan mission Live Updates: Where is the test flight going?
Gaganyaan mission Live Updates: The upcoming Flight Test Vehicle Abort Mission-1 will demonstrate the Crew Escape System's performance. It's the first of two abort missions designed to test the safety mechanisms that will enable the Gaganyaan crew to evacuate the spacecraft during an emergency. During the test, the rocket will ascend to an altitude of nearly 17 kilometers before triggering an abort signal. This will lead to the separation of the crew module, which will descend using a parachute, eventually splashing down in the Bay of Bengal.
According to ISRO, the meticulous planning includes deploying a series of parachutes to ensure a safe descent, with the Indian Navy stationed at a safe distance with a ship and a team of divers ready to recover the module. The "short duration" test is expected to last about nine minutes.
