India today has scrubbed Monday's launch attempt of their GSLV-F06 rocket with the GSAT-5P satellite bound for geostationary orbit.
The launch countdown was due to pickup at the T-29 hour point, however "a minor leak in one of the valves of the Russian Cryogenic stage" was discovered during checks of the vehicle prior to picking up the count, the country's Satish Dhawan Space Center stated.
The cryo stage in question is the third stage which uses a mixture of super cold liquid oxygen and liquid hydrogen to burn the stage's KVD engine.
The 161-foot white rocket uses four strap-on liquid rocket boosters and a solid fueled core engine at launch. The core engine's burn time is about 100 seconds.
A new date will be announced in the coming days, the space center adds, once the reason for the leak is discovered.
A GSLV launch last April resulted in it's satellite reaching a lower than planned orbit and being lost.
