Falcon 9 second stage tested
Successfully: http://spaceflightnow.com/news/n1001/05falcon9/
It's now on its way to the Cape after a full flight duration burn test. SpaceX seems to be shooting for a March lift-off. The Dragon test spacecraft will be inserted into a 155 mile high orbit if all goes well. I'm really hoping that they stick a camera on the Dragon capsule so it can transmit some images back from orbit. Pat |

I'm really hoping that they stick a camera on the Dragon capsule so it can transmit some images back from orbit. I'm really hoping they'll stick cameras on the upper stage with a view of the engine nozzle, so we'll have fewer things to guess at what went wrong. Not normally a betting man, but I'm giving 50-50 odds of the first launch getting into orbit. Better than Falcon 1 because they're flying a lot of better-tested hardware this time around. I don't expect any problems from the first stage. --Damon |

I don't expect any problems from the first stage. I'm on the flip side of that; I'm expecting trouble with the first stage due to harmonic vibrations from so many engines firing at once, but think the second stage will have fewer problems due to fewer engines. Like you though, I'd give it around a 50-50 chance of working right on the first flight. Pat |

I'm betting there is a 100 chance that no matter what happens the
SpaceX PR department will call the launch a success As for the Dragon, I thought it was essentially boilerplate, no "smarts?" rick jones -- The glass is neither half-empty nor half-full. The glass has a leak. The real question is "Can it be patched?" 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... |

What no sub-orbital test first? How will they vouch for the capsule integrity if they can't inspect it? Telemetry, shelemetry!! Show me the friggin thing back on the ground first before I put my a$$ into it! Beside if they don't de-orbit it, how will Elon Musk get back his 1 MEEELION dollars? Oh of course, ANOTHER X PRIZE!!! BRILLIANT!!! ;-) Dave |

The artist's impression of a Dragon launch as presented at: http://www.spacex.com/dragon.php doesn't show an escape tower. Now, whether that is an omission on the part of the artist or reflects actual design I do not know. According to this, the service module houses some sort of abort system: http://www.spaceref.com/news/viewnews.html?id=1095 "Below the capsule (crew compartment) is an integrated service module. In addition to on-orbit operations, the service module can also provide the combined crew compartment/service module with the ability to pull the entire crew and cargo off the pad or out of the flight path should an abort be required." That's going to be a pretty formidable system to separate that much mass. Pat |

They hope to have the US Taxpayers (or debt-owers) also fund that with the COTS phase D contract. It will be fun to watch F9 staging on webcam. Glen Overby |
