Good luck, Falcon 1
Even though I can't see the launch, all the very best.

: Even though I can't see the launch, all the very best. Looks like a launch failure. There was visible roll oscillation after the first minute, but during first stage operation. Video went off and SpaceX's announcers don't have a clue. We'll have to wait for the failure analysis, but I'm guessing there was a guidance system problem from the oscillations. --Damon |

Here's a timeline of what was supposed to happen and when: http://spaceflightnow.com/falcon/003/timeline.html When the program got going, Elon Musk said he could afford three failed launches... this is failed launch #3. I'll bet they'll live to regret trying the second launch inside of a hour after the aborted one without looking the vehicle over and trying again tomorrow. At this point, I'd be looking a bit askance at Falcon 9. ;-) Pat |

At this point, I'd be looking a bit askance at Falcon 9. ;-) I'd guess the investigation will be looking at the performance of the new regen version of the Merlin, and at guidance. The roll oscillation was certainly suspicious but things otherwise looked relatively normal until the video feed quit. Possibly the vehicle was off-course, which could have been guidance or engine malfunction/underperformance. At some point a computer or flight safety pushes the red button... At about T +4 minutes, you can start to see some oscillation of the second stage engine bell--it's making small clockwise circles at just under one rev per second. They didn't seem to get much faster, but the oscillations certainly got bigger during the remainder of the flight. Also, I'm certainly no expert, but at first stage separation, there seemed to be a lot of yaw in the rocket before the second stage lit. I don't know if the first stage didn't separate cleanly, or what, but it just looked odd. take care, Scott |

Two different stories now... Musk said everything was going perfect till explosive bolts that were supposed to separate the two stages failed to fire despite a doubly redundant firing system (not Russian explosive bolts by any chance? ;-) ). People who watched the video say the vehicle developed oscillations well prior to stage separation. After the anomaly, all contact with the rocket was lost, so no one knows exactly where it ended up. Anyway, the ashes of Scotty and Gordon Cooper now lie in a watery grave, along with those of 206 other people. "A space launch vehicle? Ai...and if my grandmother had wheels, she'd be a cart." Pat |

Watching the vid of the Ist launch attempt,(haven't got to Launch 2 yet,I'm on dial up etc) seems like there was a party going on in the background...!! Guess they are being just too "gung ho".......Maybe the mystery investor is Bill Gates,who might "give" 'em a few Gidzillions .................? Anyway,what a crying shame....................... |

If they can't manage to properly incorporate explosive bolts, then what else is marginal or deficient? What was the all-inclusive inert GLOW of Falcon? ~ Brad Guth Brad_Guth Brad.Guth BradGuth |
