Gaganyaan Mission: First Test Flight Launch Date, Time, Venue, How To Watch And More
The crew module will be recovered after touchdown in the Bay of Bengal, using a dedicated vessel & diving team from Indian Navy.
The Indian Space Research Organisation on Monday said it would commence unmanned flight tests for the Gaganyaan human spaceflight mission with the launch of a test vehicle this week.
Gaganyaan project envisages a demonstration of human spaceflight capability by launching crew of 3 members to an orbit of 400 km for a 3 days mission and bringing them back safely to earth, by landing in Indian sea waters.
The Test Vehicle Development Flight (TV-D1) is aimed at testing the crew module (CM) that will carry Indian astronauts during the human spaceflight late next year.
The TV-D1 test flight involves launching the unmanned crew module to outer space, bringing it back to earth and recovering it after touchdown in the Bay of Bengal.

Mission Gaganyaan: First Test Flight Date, Time And Venue
Gaganyaan mission's Flight Test Vehicle Abort Mission-1 (TV-D1) will be launched on Saturday, October 21 at 8 AM IST. The test is scheduled from the First launchpad at SDSC-SHAR, Sriharikota.
Gaganyaan Mission Launch Live Telecast And Live Streaming
The TV-D1 test flight launch will be telecast live on DD News Channel. ISRO will livestream the launch on its website and social media handles.
ISRO Chairman S Somanath last week told reporters that three more test vehicle missions would be launched under the Gaganyaan programme after the TV-D1 test flight on October 21.
"The first test vehicle flight (of the Gaganyaan mission) will be conducted on October 21. After that, we have planned for three more test missions, D2, D3, D4. We will hold thorough tests during the test flight sequence," Somanath, who is also the secretary, the Department of Space, had told reporters in Rameswaram.
According to ISRO, the test vehicle is a single-stage liquid rocket developed for this abort mission. The payloads consist of the Crew Module (CM) and Crew Escape System (CES) with their fast-acting solid motors, along with CM fairing (CMF) and Interface Adapters.
"The Crew Escape System with Crew Module will be separated from the Test Vehicle at an altitude of about 17 km. Subsequently, the abort sequence will be executed autonomously commencing with the separation of the CES and deployment of the series of parachutes, finally culminating in the safe touchdown of CM in the sea, about 10 km from the coast of Sriharikota," ISRO said.
The crew module is where the astronauts will be contained in a pressurised Earth-like atmospheric condition during the Gaganyaan mission. The CM for the Gaganyaan mission is under different stages of development.
For the TV-D1, the CM is an unpressurised version that has completed its integration and testing.
"With its complete set of parachutes, recovery aids actuation systems and pyros (pyrotechnic device used to separate spacecraft from rocket), the avionics systems in CM are in a dual redundant mode configuration for navigation, sequencing, telemetry, instrumentation and power. The CM in this mission is extensively instrumented to capture the flight data for evaluation of the performance of various systems," it said.
The crew module will be recovered after touchdown in the Bay of Bengal, using a dedicated vessel and diving team from the Indian Navy.
