CEV and Stick
Has the final CEV design been chosen and what will it look like, the Lockheed design with small winglets or will it be a complete modular design like the Apollo spacecraft? As far as I know the launcher for the CEV will be a 2 stage launcher rocket composed of one solid rocket boster and one J2S/SSME upper stage. I believe this configuration can send the CEV to the moon using the upper stage? Would it be possible to just use the SRB to put the CEV in orbit only? I heard something about make two types of CEVs? I think they should just make one CEV design. I have read many posts in the past from people who dont like using the shuttle parts, SRBs, SSME, in the new spacecraft but rather use EELVs.(delta, titan, atlas) I dissagree, I believe the SRBs are safe. The initial explosion of Challenger came from gas entering into the SSMEs, but the SRBs did not cause the explosion. The SRBs did not explode first, right? ATK Thoikol said that SRBs donot explode. They burn at a "perscribed rate". Thats what it says somewhere on this website, which I like. http://www.safesimplesoon.com/default.htm |

The disaster's root cause was a leaking SRB field joint.

No, but Griffin's big blueprint plan, which lays out the launch vehicles and an outline of the spacecraft, is being released during the next day or three, first to the White House, then to NASA Centers, then to the public next week. Keep your eyes on "www.nasawatch.com", "space.com", etc., for the latest. Early hints are that the plan is to develop an SRB-based CEV launcher quickly to replace shuttle. A Saturn V class shuttle derived launcher might follow in a decade or so. - Ed Kyle |

An unmanned SRB/SSME launcher would be able to boost about the same, if not more, payload mass into orbit as a space shuttle payload bay. A Progress-like unmanned CEV with a heat shield could be used to deliver and return mass. What has shuttle been returning to earth that couldn't return in a CEV? - Ed Kyle |

(in article . com): What has shuttle been returning to earth that couldn't return in a CEV? You ought to qualify that question with the word "lately" or "recently" else some smart ass (like me) will respond: "LDEF, Palapa-B2 and Westar VI . . ." :-p -- "Fame may be fleeting but obscurity is forever." ~Anonymous "I believe as little as possible and know as much as I can." ~Todd Stuart Phillips www.angryherb.net |

The SRBs did not explode prior to RSD, nor did they cartwheel. However, it's incorrect to exclude the SRBs as a cause of the explosion. The SSMEs effectively destroyed themselves, from operating with an oxygen-rich propellant mixture; but that was more a case of insufficient hydrogen (the fuel) "entering into the SSMEs."

David, you're dealing with John Thomas Maxson, a former Lockmart janitor who's pretending to be an engineer who was fired for supposedly blowing whistles about SRB problems to his superiors. Most of us here have the senile old ****wit - as well as his inbred excuses for offspring - killfiled. Every claim he makes is 100% bogus, and reading his posts, much less responding to them, is a waste of your time and our bandwidth. Please, just toss him in a killfile where he belongs and put him out of *all* our misery.
