Weak Russian component downed Indian rocket: Ex-ISRO chief Chennai, April 22 (IANS) The destruction of India's Geosynchronous Satellite Launch Vehicle (GSLV) in mid air in 2010 was due to an inherent weakness in a component in the Russian supplied cryogenic engine. "We did several simulation te...

Was there only ONE set of connectors going to first stage? No redundency built into the system, No duplicate control paths?

AFAIK, every aircraft/rocket systems have multiple level of redundency. I think, GSLV must have been designed with multiple fault tolerent systems. Also the cables are redundent and their paths are laid from different location. So even if one path fails, other is active. If they havent done that the...

I was wondering why ISRO went with an actual satellite instead of dummy satellite/payload for this launch? Desi cryo engine was untested and there was not need to pair it will an actual satellite to double the failure cost. They could have tested the flight parameters equally well with a dummy paylo...
