There's talk now that there may be some Shuttle components used on the finished system (probably for an unmanned cargo carrier) and that they may want the CEV to be larger than currently planned: http://www.newscientist.com/article.ns?id=dn7345 Using the Shuttle's ET and SRBs on a unmanned cargo carrier would at least vastly decrease the number of launches needed for a lunar landing mission over what could be done with Delta IV Heavies. One of the main things that worked against the Shuttle cargo versions was the need to try and recover the SSMEs due to their cost, but two of the Delta IV's RS 68s give around the same thrust, and they are designed to be expendable. Operating costs of such a vehicle could be kept low due to the amount of man-hours that could be saved in not having to deal with the orbiter's refurbishment and upkeep. Pat |

However, the silicone rubber mold is up and running, with two good casts made; the extra bits for the aft end - flaps, RCS, hatch - are now embedded within silicone rubber, hopefully with first casts made sometime tonight. Should be in limited production tomorrow (limitted because I'm about out of resin, and the manufacturer no longer sells directly to the public, the *******s). |

Apparently someone's dug up the old Shuttle-C papers, and pointed out that there's really nothing wrong with the basic ET & SRB configuration if you're just using it to boost cargo, and some costs could be cut by keeping the Shuttle-C and using the existing Shuttle pads. Again, this whole mess is going to have to go back to the drawing boards at least three or four times, but keep in mind that happened with the Apollo Block I at least twice before they finalized the design.

Emphasis on the word "could". That's not the same as "would". Generally speaking, you cannot get a truly low-cost process by paring bits off a high-cost one. You have to build it from scratch, adding only the bits that are absolutely necessary. Dave Urie of the Lockheed Skunk Works, asked in 1997 about the idea of launching VentureStar from LC-39, said: "It's cheaper to build new pads." -- "Think outside the box -- the box isn't our friend." | Henry Spencer -- George Herbert | |
