Space-X Dragon
With all this talk about the CEV, I thought I'd try to drag the discussion
over to NASA COTS and ISS resupply. The latest pictures on Space-X's web site of their Dragon capsule look pretty good. I think the baseline CBM is a good thing. Here's their highlights: Dragon Highlights: - Fully Autonomous with Manual Over-ride capability in crewed configuration - Pressurized Cargo/Crew capacity of 3100 kg to ISS orbit - Supports 7 passengers in Crew configuration - Down-cargo capability (equal to up-cargo) - Integral CBM, with LIDS or APAS support if required - Designed for Water Landing under Parachute (Ocean Recovery) - Lifting re-entry for landing precision & low-g's With the integrated CBM, I'd think that the cargo version would be fairly easy to deal with once it's been berthed to ISS.

The Capsule Lockheed shows ontop of the Atlas V, has no Escape tower. Wonder what the crew escape plan will be for it? Carl |

Henry,
Escape rockets can be placed underneath; there's no law of nature that says they have to be on top. And as you have pointed out previously, there are several laws of nature that strongly suggest putting them on the bottom. ~Jon |

Any manned spacecraft that *doesn't* suffer a critical failure during launch, is going to require additional propulsion for e.g. circularization and eventual deorbit. The delta-V requirements for these are comparable to the delta-V requirements for launch escape, and there's no reason you can't use the same propulsion system for both. -- *John Schilling * "Anything worth doing, * *Member:AIAA,NRA,ACLU,SAS,LP * is worth doing for money" * *Chief Scientist & General Partner * -13th Rule of Acquisition * *White Elephant Research, LLC * "There is no substitute * * for success" * *661-718-0955 or 661-275-6795 * -58th Rule of Acquisition * |

Yes I remember the plans for Gemini & Gemini B to use that method, (and or ejection seats at lower speeds). Remember John Young Said, (When he observed a failed Gemini ejection test), "If the door fails to open when You pull the handle, It will be a hell of a headache, (But a very short one)". I was just wondering what Lockheed & Space X, plan. As for Space X building the Dragon, (I would look for it to be test flown in less than (2) years). As for Lockheed, (It is safe to say that the comm. cap. for the Atlas V will fly sooner than the CEV). As for the Russians, (The tech base is solid, (Thanks to Clinton/U.S. Tax Dollars, saving them)). I would look for them to continue to retrofit, and reconfig Soyuz, for many moons to come. As for the China theft program, (Look for it to cont. unhindered as long as the Happy Meal toys keep shipping). Am I The only one who sees another Boxer Reb. building there? I would not be concerned with our ability to design, or construct, space craft in the good old USA. I would be more concerned about a do nothing congress, and or, B. A. or H.C. getting into the whitehouse. You think We are screwed up now, (What a nightmare village that would be, for any ongoing design/build U.S. space projects). I think India will be the folks to watch, (They are dev. it all on a shoestring, and with home grown tech.). I admire the way the handled the Russians giving them the finger on the upper geo. kick stage project. They just went home and did the R & D. We are so busy watching how fast corn goes thru our bodies, that the race may be lost soon. Is there a third choice to put in power next round, (Good I hope the light at the end of the funding tunnel, ain't a gorilla with a flashlight). Carl |

How far are Spacex to go in the "demonstration"? Are they not also building a working spacecraft. Isn't there a risk that Dragon plus a Service Module could make Orion redundant? |

Yes, and lately they haven't done too well at it -- their history in that area has been an unbroken string of failures and canceled projects. These days, they too specialize in computer-generated pictures and lists of nice features. It's not clear that they *know* how to build working spacecraft any more -- the guys who built Saturn and Apollo, and even the shuttle, are gone now. -- spsystems.net is temporarily off the air; | Henry Spencer mail to henry at zoo.utoronto.ca instead. | |
