Post flight inspection could reveal problems with the luanch vehicle which would otherwise go unnoticed. Jeff Absolutely; I couldn't agree more. I've read that SpaceX does intend to re-use the first stage. |

Falcon 9 - First stage to be recovered!
I thought the whole problem with first stage reuse was the ingress of salt
water into the mechanisms etc. Its a nice idea but might it not cost more than a new one?

@viwinnwfe01.internal.bigpond.com: http://www.spaceflightnow.com/falcon9/002/status.html Weather permitting. Reportedly only debris found, and what I think was a prototype suborbital package with a "black box" data recorder. No details on the recovery systems, which I presume include parachutes. --Damon |

Falcon 9 - First stage to be recovered!
In article om,
says... I have to admit to being a sceptic that "cots" would lead to real services being offered. I saw it as mostly "make work" pork project likely to be cancelled before any real results were to be seen . Considering the tiny amount of money NASA is spending on COTS ($500M from 2006 through 2011 - cite below), I'd hardly call it pork. http://www.nasa.gov/offices/c3po/about/c3po.html Yesterday's flight is changing my mind. Is this a big game changer ? Is Boeing nervous that it will now have to stop milking the government for tons of money to accomplish space travel because some new kid on the block can now actually deliver stuff much cheaper ? They've only got 1200 employees, and even though SpaceX is vertically integrated, meaning they build most of the hardware themselves, they've pulled off a feat which the skeptical thought would not be possible. They've developed their own launch vehicle and large capsule and have demonstrated the orbital launch and recovery of that large capsule at a fraction of the cost predicted by NASA cost models. BTW, at: http://www.spaceflightnow.com/falcon9/002/splashdown/ the first image shows the Dragon wirth its 3 red-white parachutes and at some distance, there is another object falling with 2 or more white parachutres. What is that ? Does Dragon end-up re-entry as two survivable units ? I'd guess those are the drogue parachutes. Either that or it's the nose of the capsule, perhaps being recovered for post flight inspection. Jeff -- 42 |

They've only got 1200 employees, It remains to be seen how many more employees they'll need when they have to start building and launching 10 or more Falcon 9s a year. I hope the company has a good plan for ramping up from essentially an R&D organization into a full-scale operational service. the first image shows the Dragon wirth its 3 red-white parachutes and at some distance, there is another object falling with 2 or more white parachutres. What is that ? Does Dragon end-up re-entry as two survivable units ? I'd guess those are the drogue parachutes. Correct. Either that or it's the nose of the capsule, perhaps being recovered for post flight inspection. The nose cone was jettisoned during launch. Brian |

NASA didn't develop or fund EELV (Boeing's Delta IV and Lockheed-Martin's Atlas 5), the Pentagon did. or let me ask this differently: When Boeing builds a commercial satellite launcher, are its costs much lower and closer to SpaceX's costs and it is only work done for NASA that is bloated ? No, as evidenced by Delta IV's complete failure in the commercial market (Boeing/ULA don't even market it anymore.) Brian |
