The cancellation was prudent, considering the last attempt to launch the rocket had ended in disaster. In December 2010, a GSLV with a Russian engine had exploded 63 seconds after the blast-off. Another effort in April that year, with an indigenous cryogenic engine, had failed as well.
The countdown was stopped all of a sudden, an hour and 14 minutes before the launch, scheduled for 4.50 pm. “A few minutes ago, we detected leaks in the in-fuel system of stage two. Because of this, we are calling of this launch,” said ISRO chairman K Radhakrishnan.
A new date will be announced after the damage by the leak has been assessed.
