ISRO will conduct three more test vehicle missions under the ambitious Gaganyaan programme after the maiden TV-D1 test flight, which is scheduled on October 21, the space agency's chairman S. Somanath said on October 14.
The Gaganyaan project envisages a demonstration of the human spaceflight capability by launching a human crew to an orbit of 400 km and bringing them safely back to earth by landing in Indian sea waters.
The test vehicle development flight (TV-D1) will be conducted at the Satish Dhawan Space Centre in Sriharikota in Andhra Pradesh to test the crew module that is scheduled to house Indian astronauts during the human spaceflight late next year.
