NASA Drops Requirement For Methane Engine From CEV
In some respects I not suprize to see it happen. Though the
requirement was a little much for a lunar craft. Bit suprized they dropped the requirement for unpressurized payload deliverly to ISS, but it didn't say anything about deleting the ablity for pressurized payload delivery. http://www.aviationnow.com/avnow/new...s/CEV01126.xml NASA Drops Requirement For Methane Engine From CEV By Frank Morring 01/12/2006 08:38:34 AM Congressional pressure to avoid a gap in U.S. human space access is behind a NASA push to accelerate the first piloted flight of the planned Crew Exploration Vehicle (CEV). While President Bush originally wanted an operation CEV by 2014, the final RFP for the shuttle replacement called for a first flight with crew "as close to 2010 as possible, but no later than 2012, without compromising safety." The new document also drops requirements for a LOX/methane engine on the CEV service module as a placeholder for future extraction of the fuel from the atmosphere of Mars, and for delivery of unpressurized cargo to the International Space Station, although nothing would prevent the winning team from proposing them, according to a program spokesman at Johnson Space Center. Officially a "call for improvements" to the original CEV bids, the long-awaited document specifies for the first time that the vehicle will be "an improved, blunt-body crew capsule shape" as called for in the exploration architecture released last fall (Aviation Week & Space Technology, Sept. 26, 2005). Final CEV dimensions remain in flux, the program spokesman says. Teams led by Northrop Grumman and Lockheed Martin are finalists for the job of building the CEV, which will run through 2019. The contract will fall into three parts - a cost-plus award fee element through "approximately 2013" that will cover design, development, test and evaluation (DDT&E) though first flight of the initial two CEV blocks; an indefinite quantity indefinite delivery contract for full-scale CEV production, and a sustaining engineering element that will include "any additional DDT&E necessary to complete development of the Block 2 Lunar variant."

NASA Drops Requirement For Methane Engine From CEV
This is just the first cut, we can watch as the program started with
good ideas shrinks to just a LEO manned and unmanned craft. all the rest will be lost... no moon, no mars... no nothing... |

Oh God, I'm so relieved. Since the moon and mars will be ultimately lost, we don't have to worry about them colliding with the Earth anymore, and thus there is no need for us to go there at all to divert them into safer orbits. We'll save a bundle of money, and all our space assets and resources can then be directed to asteroids on near term collision courses with the Earth. Civilization is saved! Cudos all around.

Good, it's a joke. We need to kill it RIGHT NOW. ultimately the US space program is going to go no where but maybe round and round. I hate to be the one to have to lay it out for you, but the Earth revolves around the sun, the moon revolves around the Earth, Mars revolves around the sun, asteroids revolve around the sun the moons of Mars revolve around Mars, even the sun revolves around the center of the galaxy. The galaxy is rotating. Everything is going round and round. It's the collisions that we are worried about. As far as I know, the moon and Mars are not going to collide with the earth any time soon. Yes, building an SRB powered CEV to go to the ISS is PRETTY ****ING DUMB! Thank George Bush and Michael Griffin for that little piece of intelligence. We need methane powered engines almost as much as we need a national debt of 10 trillion dollars. http://cosmic.lifeform.org |

Going nowhere? We are going to Pluto in a few days. Is that far enough out there for ya? George |

George man wise we arent going anywhere but ISS. futhermore I doubt we
ever will in say next 30 years.... |

NASA Drops Requirement For Methane Engine From CEV
About the methane engines.
If CEV is to participate in a mars mission, it will be only as a tag along to a real ship. It might be used to crash land astronauts on the surface, but it won't be able to take off. The capsule won't have engines. So outfitting it with methane engines is pointless. Outfutting the real mars expediation ship/station as well as designing the ship that takes off from mars to get back to the expedition ship/station with methane engines makes a lot of sense since those are the ones that will want to be refueled from mars produced fuel. So, until NASA begins work on the real mars expedition ship as well as the real mars landing ship that can take off again, the methane engines aren't needed. Since NASA has realised the mistake of prematurely retiring Shuttle, it needs the CEV up and running ASAP to service the station. And that means cancelling anything that doesn't exist yet. They only have 4 years go go from an idea to a production vehicle. A whole lot of neat features will be dropped for the sake of getting CEV out in time. And consider how much fuel you will need to lift from mars to refuel the expedition ship for a return to earth. We're not talking about the type of payload a LEM type of vehicle could lift from mars. So you're either going to need of small cargo rockets to lift fuel up intomartian orbits one bit at a time, or one hunking big rocket like a delta 4 that has enough uplift capacity to lifte the fuel needed to get back to earth. You might be able to produce enough fuel on mars to get a LEM type vehicle to lift off from mars and rejoin the big expedition ship. But it doesn't seem realistic to me that you could have a rocket big enough to not only lift off from mars, but also carry all the mars=produced fuel needed to get back to earth in the big expedition ship. Perhaps Bush thinks that Mars is just a week further away than the Moon and figures you could stick 6 people in a CEV and the modern equivalent of a LEM to do a Mars camping trip just by aiming the CEV at mars instead of the Moon. Oh, I also notice the requirement has now dropped to 4 people to get to the moon. Apollo had 3. In the end, NASA will end up with nothing more than a glorified Soyuz to get to the station and no serious cargo uplift to/from the station. Has NASA begun work on automated guidance and automated docking yet ? |

Like what happened when the Shuttle was propsed as the building block for a Moon/Mars architecture that was never built? Possibly. But nothing is carved in stone. The Congress that decided that there was no point in more flights to the Moon once we'd beat the Russians is not the Congress we have today. If successive adminstration remain committed to the VSE, then we will get back to the Moon and on to Mars. ----== Posted via Newsfeeds.Com - Unlimited-Unrestricted-Secure Usenet News==---- http://www.newsfeeds.com The #1 Newsgroup Service in the World! 120,000+ Newsgroups ----= East and West-Coast Server Farms - Total Privacy via Encryption =---- |
