Gaganyaan mission highlights: Proud moment for India! Test vehicle launched, splashed down safely in Bay of Bengal
Gaganyaan mission Launch: Today’s unmanned test flight, dubbed Flight Test Vehicle Abort Mission-1 (TV-D1), has successfully been launched and the test vehicle has been safely dropped down in the Bay of Bengal. This blog is now closed.
Gaganyaan mission first test flight launch: The TV-D1 test flight was temporarily halted due to an anomaly found during the launch sequence. The ISRO chief said that the team will go back to understand what went wrong and will come back with the findings. At 9:35 AM, the agency revealed that the issue was identified and corrected. The test vehicle has now been successfully launched. Testing the abort mechanism, the test vehicle has been safely splashed down in the waters of Bay of Bengal. This mission is being carried out by the Indian Space Research Organisation (ISRO). It should be noted that today’s launch by ISRO is not going to have any human astronauts inside the test vehicle. It is just to see whether the Gaganyaan mission is sustainable and to collect data. The Gaganyaan test vehicle will launched from Satish Dhawan Space Centre in Sriharikota.
What is it aim of the mission?
The Gaganyaan program is a two-fold endeavor. In the short term, it aims to demonstrate India's prowess in human spaceflight, sending astronauts to Low Earth Orbit (LEO). This mission will lay the foundation for a sustained Indian human space exploration program in the long run, solidifying the nation's position as a key player in space exploration.
As part of this program, the government of India has given the green light to two uncrewed missions and one manned mission.
What will happen during the abort demo test?
The test vehicle will be launched from Satish Dhawan Space Centre in Sriharikota. At 11.8 kilometres, the HEM firing will be activated. Then, the crew escape system phase will begin in which the booster will be separated and splashed into the ocean. Then at 16.8 kilometres, coasting will take place during which the CES and crew model will prepare for separation. Then ISRO will activate Apex Cover Separation in which the CES and crew model will be finally separated. The crew model will fly down to the ocean till its final descent with the main parachute. Lastly, the CES will splash down into the ocean 14 kilometres away from the crew model.

Gaganyaan mission Live Updates: ISRO chief gives mission details
Gaganyaan mission Live Updates: ISRO chairman S. Somanath said,“I'm very happy to announce the successful accomplishment of the TV-D1 mission. The purpose of the mission was to demonstrate the Crew Escape System (CES) for the Gaganyaan program through a test vehicle demonstration in which the vehicle has gone slightly above the Mach number that is the speed of sound. The CES took the crew module away from the vehicle and the subsequent operations by the crew, parachutes opening, and touchdown in the sea at the required velocity has been very well accomplished. We have received confirmation of data on all of this”.

Gaganyaan mission Live Updates: Where is the test flight going?
Gaganyaan mission Live Updates: The upcoming Flight Test Vehicle Abort Mission-1 will demonstrate the Crew Escape System's performance. It's the first of two abort missions designed to test the safety mechanisms that will enable the Gaganyaan crew to evacuate the spacecraft during an emergency. During the test, the rocket will ascend to an altitude of nearly 17 kilometers before triggering an abort signal. This will lead to the separation of the crew module, which will descend using a parachute, eventually splashing down in the Bay of Bengal.
According to ISRO, the meticulous planning includes deploying a series of parachutes to ensure a safe descent, with the Indian Navy stationed at a safe distance with a ship and a team of divers ready to recover the module. The "short duration" test is expected to last about nine minutes.
