Gaganyaan mission: How ISRO resolved the glitch in 45 minutes and relaunched the rocket. 10 point

Saturday’s launch was not easy after the rocket was temporarily held at 8:45 am. However, after analyzing the fault, the scientists resolved it in just 45 minutes and attempted a second launch.

At 10:00 am, the test vehicle TV-D1 was successfully launched from Sriharikota. The rocket tested the emergency escape system of its crew module, which separated from the thruster and made a soft landing at sea about 10 minutes after launch.

Here are 10 updates on ISRO’s Gaganyaan TV-D1 mission:

1. Initially, ISRO planned to launch the Flight Test Vehicle Abort Mission, a key part of its ambitious man space mission Gaganyaan, at 8 am. But it was later moved to 8:30 am. However, at 8:45 a.m. the launch of test vehicle D1 could not take place.

2. The TV-D1 launch suffered two delays when a “hold” signal flashed across the screens at the Satish Dhawan Space Center as the final countdown was underway.
