Gaganyaan Mission: Why Did TV-D1 Rocket Failed To Lif Off?

By Consultants Review Team Saturday, 21 October 2023

On Saturday morning, the Indian Space Research Organisation (ISRO) suffered a huge setback when the TV-D1 test rocket failed to lift off.

Just five seconds before the launch at Sriharikota, the unmanned test vehicle entered 'hold' mode. Engine ignition did not occur throughout the nominal course of the Gaganyaan mission test vehicle, according to ISRO Chief Somanath.

"Will come back soon after analyzing what triggered the automatic launch sequence holding the vehicle," the director-general of ISRO stated.

The first unmanned flight test, known as the Test Vehicle Development Flight Mission-1 (TV-D1 Flight Test), was scheduled to begin today at 8:30 a.m.

The test vehicle was designed to investigate the safety of the crew module and crew escape system in the ambitious Gaganyaan mission to return Indian astronauts to Earth.

The test flight's success would have set the stage for future qualification tests and uncrewed missions, eventually leading to the inaugural Gaganyaan program.

The TV-D1 Vehicle, a liquid-propelled single-stage Test Vehicle, was powered by a modified VIKAS engine with a Crew Module (CM) and Crew Escape System (CES) installed at the front.

The chairman of ISRO has stated that they will investigate the problem that occurred today and will soon announce a new launch date.
