TV-D1) was a high altitude abort test performed as part of the Gaganyaan program, initially set to be held on 21 October 2023 at around 02:30 UTC. Liftoff was delayed to 03:15 UTC due to weather issues, and five seconds before launch it was put on hold by the on-board computer due to an engine anomaly, as reported in ISRO's mission livestream. The launch occurred at 04:30 UTC, and the crew module successfully separated from the launch vehicle. The crew module was successfully recovered by the Indian Navy. India is the fourth country, after Russia, the United States, and China, to successfully test this technology.
