Looks like Russia lost another Proton rocket. I suspect the flew off course and exploded really means "flew off course and range safety destroyed it". |

Like 2 booster failures in a row ground soyuz, the capsules expire, so the crews are brought back and ISS which requires constant human repairs has a glitch and starts tumbling unmanned..... imagine a out of control ISS sheding modules and dropping them randomly on their ground track..... |

I was looking at an embedded video on theatlantic.com - looked like if range safety did terminate the rocket with extreme prejudice they seemed to wait quite a while. I suppose some of that was "wait till the damn thing clears the launch complex" but even then it looked like they might have waited rick jones -- web2.0 n, the dot.com reunion tour... these opinions are mine, all mine; HP might not want them anyway... feel free to post, OR email to rick.jones2 in hp.com but NOT BOTH... |

: bob haller
: imagine a out of control ISS sheding modules and dropping them : randomly on their ground track..... Ha! Oh my. Bob prolly thinks if you drop something while on a spacewalk it'll also fall randomly on the ground track. Probably one of those who think an orbit is like a little train track in the sky. Most amusing. The things people like Bob can get to worrying about. Must amusing indeed. I mean, not that it wouldn't be a problem if control of ISS were lost. But the projected scenario... most amusing. |

I suspect the flew off course and exploded really means "flew off course and range safety destroyed it". This really looked like an out of control booster. Before whisking off to arocket I'm going to speculate that it was an engine gimbal hydraulic failure due to a catastrophic leak, perhaps a seal failure, which caused an engine to gimbal wildly off-axis which sent the booster off course. Notice the reddish colored gas coming from the rear at 0:09 in this video: http://www.youtube.com/watch?v=ogUkEpBRNUg which is not undergoing combustion. Now that I've placed my bet its off to A-rocket to check.... Dave |

Proton Failure
Guess I should not read too much into that reddish gas...
From: http://orbiter-forum.com/showthread.php?p=427616 /quote Well, there is one important detail: The Proton rocket has only single gimbal TVC for its first stage engines. A missing or malfunctioning engine could easily result in an uncontrollable rocket. Some German reading about the Proton: http://www.bernd-leitenberger.de/proton.shtml Interesting is also his own explanation of the brown smoke during normal launch: One engine is throttled down by a mixture ratio shift resulting in unburned N2O4 getting released, maybe for a faster initial pitch over. It is ALWAYS the same engine involved in all launches. /end-quote |

When skylab deorbited everyone was told it would fall somewhere on its ground track and what percentage was over ocean........ a ISS with no astronauts.... control could be lost.... |

I had not seen the video (and in fact the picture I saw showed a Soyuz rocket :-) Interesting they don't have flight have flight termination charges. I can sort of see the argument, but.... -- Greg D. Moore http://greenmountainsoftware.wordpress.com/ CEO QuiCR: Quick, Crowdsourced Responses. http://www.quicr.net |
