ISRO attempted a Flight Test Vehicle Abort Mission, a key part of mission Gaganyaan, on October 21. However, the lift-off attempt failed because engine ignition could not happen in a nominal course. Gaganyaan Test Vehicle- Demonstration launch was put on hold at T-00:05 seconds. Later, taking to X, ISRO shared information that the reason for the hold was identified and corrected. Now, the Gaganyaan Test Vehicle- Demonstration launch is planned at 10:00 am.
