Kiss It Goodbye( I Told You So)
CEV Update
April 16, 2006 This coming week is a time of decision for the CEV/CLV program. We are back to a 4 segment SRB. The 5 segment SRB 1st stage required an additional $1,000,000,000 next year to certify for flight. They wanted to change the propellant grain. This was driving a full test program and a massive amount of analysis. Simple put, the SRB program was starting over. We may add a second J-2 engine to the upperstage of the CLV to get more energy. However we can't make the 2nd stage much wider or the SRB will snap. The option to add a third stage to the CLV is out. A three stage CLV would not fit out the VAB doors. The Launch Abort Rocket design is fixed. It looks and works like the escape rocket on the Soyuz. This allow us to fly without a booster cover on the CEV capsule. Right now we can't fly the Lunar CEV SM and CM on one CLV rocket so the new plan is called "Lunar 2.5". We launch the CEV service module (minus the CEV capsule) on a CLV 1st. Followed in a day to two by a CEV Command Module and crew (minus the SM) launched by a second CLV. The CM rendezvous and docks the with SM. Followed the next day with launch of the heavy lift (HLV) booster with the earth departure stage and Lunar Lander. They all form up and away we go! One more idea from this week you might find interesting. Cancel the CLV and man rate the HLV. That will most likely not happen. It should, saves a ton of cash and gets us to one design. One more new bit. Two SRB's, one on each side of the new upperstage. Looks a lot like the Shuttle C concept with the CEV on top. Could happen. Solves the energy problem. But, it's not Monday yet. Lastly the ISS CEV will have very small version of the SM (sort of a limited propulsion module). |

Says who? http://www.spacetransportnews.com/ There doesn't seem to be a permanent link to it, but it's the second item down right now. |

" made the phosphor on my monitor glow in such a way as to indicate that: I put low credibility in anythng I read in Blogs. Trust only in credible news sources. Some blogs are credible, some aren't. Some professional news organizations are credible, some aren't. In both cases, sometimes credible people get it wrong (in this case, the story was retracted prominently, something that doesn't always happen with the mainstream press). It's not useful to make such broad generalizations. |

Sorry, Clark Lindsey's site doesn't give the proper URL when you follow a link. Try this one. http://www.usspacenews.com/ It's about four items down, now. But when you read it, did it actually give actual information, such as a source for this rather startling info? No. I don't give it much credence, for now. |
