Re: Recent GSLV Rocket Explosion in India
Thanks for sharing: it seems that the cause was some error occurred 47 seconds after the lift-off, which leaded to a higher angle in flight, which caused a stress greater than the rocket could withstand, breaking it up. Definately it wasn't their lucky day |

Re: Recent GSLV Rocket Explosion in India
K. Radhakrishnan mentioned the flight angle issue: so he said to reporters (http://www.google.com/hostednews/ap/...7ee709fd8c199e) : it's possile that a wrong angle causes a strong stress, but honestly I find surprising what happened: usually they should be built in some way that allows them to withstand higher stresses than the ordinary ones. I guess they are very disappointed for the failure |

Re: Recent GSLV Rocket Explosion in India
“The controllability was lost after 45 seconds after the lift-off. The control commands to the four strap on motors of the first related stories GSLV mission fails, rocket explodes stage did not reach,” ISRO chairman K Radhakrishnan told reporters. He said the first stage performed well till 50 seconds, and after that the rocket started failing. According to him, the destruct command was issued 63 seconds after the lift off by the Range Safety Officer. The 2,310 kg GSAT-5P satellite, costing about Rs 125 crore, was to serve the needs of the telecommunication sector and the weather department. So about $27,765,457 |
