GSLV rocket blasts off, but no signal

SRIHARIKOTA - India’s GSLV D3 rocket, powered for the first time by an indigenous cryogenic engine, blasted off on time here Thursday with a GSAT 4 satellite. But there was tension minutes later as the rocket stopped emitting signals.

After the rocket attained a height of 60 km, scientists at the control room here said they’d stopped getting signals.
