 Watch as the crew module for Gaganyaan TV-D1 safely splashes into the Bay of Bengal

After overcoming early difficulties, the Indian Space Research Organization (ISRO) launched a test spacecraft carrying payloads for the ambitious Gaganyaan human space travel program.

In order to transfer the Crew Module out of the test spacecraft, TV-D1, ISRO scientists simulated an abort scenario as they performed a scheduled, precise splashdown into the Bay of Bengal.

The ground computer, also known as the autonomous launch sequence computer, issued a hold after the normal liftoff procedure at 8:45 am. It recognized some type of non-conformance after the engine and kept on shoving to go forward.

According to the ISRO scientist, the error occurred "as a result of a monitoring abnormality in the system. Consequently, we were able to quickly detect it and fix it.

The chairman of ISRO said, "It took some time to refill the gases and once that concluded, the team went through the proper computerized launch sequence which checked every aspect of the health of the vehicle" .

Finally, the launch was approved by the mission computer and the ground support computer, allowing the 34.9-meter-tall TV-D1 to lift off.

Somanath expressed his happiness that his team had been able to spot the error and quickly fix it.

"Congratulations to all of you. Everyone present is receiving extensive training in advance of the Gaganyaan program, and the ISRO Chairman expressed happiness that the launch occurred within the allotted launch window.

A key accomplishment for the whole Gaganyaan program, the Test Vehicle mission included the integration of a virtually finished system for a flying test.

The Crew Module System provides the crew with a livable, Earth-like habitat in space.

It contains the avionics, life support, crew interfaces, and deceleration systems. In order to protect the crew during the descent and landing, it is also built for re-entry.

Before being included into the launch complex at Sriharikota, it was put through a number of tests at ISRO facilities.
