 Posted on: Wed Nov 23, 2005 10:03 amThere is a chance to check SpaceDev's study and other studies when a few threads in the Financial Barriers section are progressed some steps further.

Posted on: Wed Nov 23, 2005 2:41 pm We will need to get a copy of SpaceDev's actual study first. Using only press releases is worse than useless.

Posted on: Wed Nov 23, 2005 2:52 pm Once the few threads are progressed further they enable to mark a lower boundary of the investments and costs - a minimum required the numbers published can be compared to by several ways.

Posted on: Wed Nov 23, 2005 5:25 pm SawSS1Jun21 wrote: It's also comparing apples to oranges, considering that Constellation is a project to develop and field a Manned Interplanetary Exploration Architecture, not simply "get to the moon on a vectored-thrust ultralight" and I expect that if the SpaceDev study had included the capacity to send humans to Mars, then the glib notion of "one tenth the cost!" would have been scaled back or absent. In the end, this begins to read like "NASA-bashing for the purposes of increasing the circulation of our press release," a practice which I find unsavory within this industry and which I would like to see stop. It is something Musk has largely refrained from doing and I think that provides him with a great deal of clout and credibility, and places him on the inside track for actually landing one of Griffin's commercial contracts. Anyway, I thought it was ironic that the boys from Poway would make this release right after publi said he liked them. Our buddy is gonna have a conniption. Rightly so, in my view. You bet I am. Its Wan Hoo all over again. The mini-Buran I love as an alternative to the stick. Moon/Mars still needs HLLV. They really disappointed me with the NASA bashing. Let them fly first, and we will see. |

Posted on: Wed Nov 23, 2005 6:04 pm I updated this blurb a bit. Here is some history behind the AMROC vehicle that seems to be the hybrid design SpaceDev is looking at:

Posted on: Fri Dec 02, 2005 4:21 pm I think this craft might make good use of the www.shuttlelift.com type technology. Only LOX is needed, and it would be more easily handled by the military--and is possibly shorter than Musks larger rocket designs.
