ISRO Gaganyaan Mission Test Flight Launched After Initial Glitch

Indian Space Research Organisation launched test flight for Gaganyaan mission after first test flight was aborted. 

The Indian Space Research Organization (ISRO) successfully launched the test vehicle of the Gaganyaan mission at 10 am from the Satish Dhawan Space Center in Sriharikota. It was named Test Vehicle Abort Mission-1 (TV-D1). In simple language, in case of any malfunction in the rocket during the mission, the system that would bring the astronaut inside safely to Earth was tested.

This mission was 8.8 minutes long. The test flight has three parts – single stage liquid rocket, crew module and crew escape system made for abort mission. The environment inside the crew module was not yet the same as it would be in a manned mission. In this mission, after going up 17 Km, the crew module was landed in the Bay of Bengal, 10 km away from Sriharikota.

Earlier today the mission was postponed twice. It was to be launched at 8 o'clock, but due to unfavorable weather, its time was changed to 8.45. The engines failed to fire 5 seconds before launch and the mission was aborted. ISRO said after some time that now the problem has been rectified. The vehicle is completely safe.

The test vehicle crew moved the module up. When the rocket was 1.2 times the speed of sound, an abort like situation was created. The crew module and crew escape system separated at an altitude of approximately 17 km. The crew module was taken about 2 Km away from here and landed in the sea, 10 Km away from Sriharikota.
