The launch was scheduled to have taken place at 2.51 am from the second launchpad at Sriharikota’s Satish Dhawan Space Centre (SDSC). The countdown to the launch was put on hold at 56 minutes and 24 seconds.
The technical snag was noticed when the cryogenic fuel was being loaded. The vehicle would need to be approached to assess the problem. The fuel loaded in the rocket would first have to be emptied, and then the rocket would have to be studied for further investigation. According to an Isro
source, the whole process would take at least 10 days. The new schedule would likely be disclosed only after that.
