Griffin Wants Inline SDLV and 5 Segment SRB/CEV
http://www.nasawatch.com/archives/20...n_wants_i.html
Wauughhhh ha ha ha...... Safe, simple, soon--but not cheap! Oh well. At least it's not better, faster, cheaper, and dead. The fact that Mike Griffen apparently already knows what he wants and how he wants to do it is tremendously encouraging to me. I might actually see humans on the moon again before I die. hallejulah. cuddihy |

I think we might see humans on the moon again with this plan. But just
for how long? The article notes that NASA wants 2 new rockets, each requiring a heavy investment. The "stick" -- a new upper stage, and the 120 tonne in-line SDHLV -- heavy capital investment in the launch infrastructure. I look at the NASA's budget and have no idea how Griffin is going to pull off a "... sustainable and permanent space exploration" (as per Bush's directives) with this plan. What exactly is he going to launch with them when all is said and done, and costing what? So far it appears that he's sinking NASA's money (and my taxes) into his old pet project (The FLO, etc...) "Any plan is better than no plan"? OK. But damn, isn't it shooting too low? |

They haven't yet sent the War On Poverty packing, so obviously expense is not an issue for Congress. -- "The only thing that galls me about someone burning the American flag is how unoriginal it is.

Boeing and Lockmart will exit the commercial launch business, leaving it to SpaceX and others to try to grab the lower end of the market. If they're lucky. That battle has already been lost. Boeing and Lockheed have already abandoned the low-rent commercial launch market for all intents and purposes. There is no competing with the low-cost Russo- Ukrainian rockets for commerical launches today. Even Arianespace has largely succumbed. Proton and Zenit have boosted seven commercial or domestic satellites so far this year, but only one U.S. launch vehicle (and it a Russian-engined rocket) has orbited a commerical payload in 2005. No other U.S. launches of commercial satellites are scheduled for the next year at least. Together, the Proton and Zenit launch total is equal to the total number of *all* U.S. space launches performed so far this year. All by itself, Sea Launch platform Odyssey has hosted nearly as many Ukrainian rocket launches as all of Cape Canaveral's pads combined in 2005. Congress will take one look at the price of that heavy SDV white elephant and send the whole thing back to Griffin with a nasty note. Griffin will argue that SDV heavy lift will save money compared to salvo-launching EELV heavies. He will argue that SDV heavy lift will cost a fraction of what it cost to build ISS (or what it will cost to conduct the lunar program altogether). If the U.S. can't afford to build an SDV heavy- lifter, then it can't afford to go back to the moon. - Ed Kyle |

Pretty much goes directly against the stated objective of buying from the commercial sector. Boeing and Lockmart will exit the commercial launch business, leaving it to SpaceX and others to try to grab the lower end of the market. If they're lucky. The Stick is a direct attack by NASA on the commercial launch services. With the Stick NASA will no longer need to buy almost any launch services. Even the Delta II and Falcon could be treatened since NASA will need to maximize launches to lower costs. Congress will take one look at the price of that heavy SDV white elephant and send the whole thing back to Griffin with a nasty note. I do not see the HSDV as half as much a problem as the Stick. The HSDV will not even really start until after 2010 and will not fly until at least the 2013-2015 time period and probably later. The Stick would need a crash program to fly near 2010. NASA during this time period needs to develop the CEV, run the Shuttle and finish ISS. This is when the funds will be stretched the tightest. Only when the Shuttle is retired do they have any additional funds. NASA is going to be stretched trying to get the CEV on line by 2010. If they put funds towards the Stick then they will not have funds to develop the CEV. If they wait they would already be launching on either the Atlas or the Delta. Totally negating any need for the stick. |

I would imagine that the Stick's upper stage would be the same as the
escape stage for the HLV that Griffin is planning, much as the role of the S-IVB. |

I might actually see humans on the moon again before I die. hallejulah. Not with this plan. Griffin just shot the VSE in the foot. There's no way he can afford to develop SDLV, the "schtick", AND the CEV on the budget available to him. Nice boner, Griffin. Congress is gonna puke when they see the bill for this jobs program. Oh well, it was interesting while it lasted. We now return you to the same ol' NASA, the National Aerospace Study Administration. (our motto, "powerpoint never killed anyone"). |

S-IVB on the Saturn V was a workaround to save time and money in the rush to land men on the moon by 1970. A far more efficient third stage would have been the same diameter as the first and second stages of Saturn V. A shorter, squatter S-IVC perhaps. Putting the narrow Stick Stage II on top of an In-Line SDLV needlessly limits the diameter of the payload on top. Brian |
