Hmm, this VTVL idea seems to me to be a deliberate attempt by Bezos to
position his endeavor for eventually taking a trip to the moon. First they go for LEO trips, and then later on they extend the use of this same spacecraft to touch down on the Moon. After awhile, they could set up a small base, then eventually a Disneyland/Hotel/etc. Then they could have REAL space tourism. Like Bigelow said, people don't want to just get a fleeting glimpse of space, they want to hang around and do stuff there. So IMHO, Bezos is planning his tech tree carefully. That means this spacecraft is not intended as a prelude to SSTO. It's intended as an upper stage and eventual moon lander. That's why Bezos wants Delta-IV engineers, so that he can build a comparable booster on which to perch this spacecraft, to get to LEO. Then later he uses it for moon landings. I know that sounds like over-imaginative speculation, but isn't it a fact that most of the energy required to get to the Moon is already achieved by rockets which can make high Earth orbit? I think Bezos is planning development of his current platform for a lot of extensibility. |

New Shepard will not come remotely close to orbital velocity, nor will it be capable of a reentry at such speeds. It's strictly a suborbital hopper for ten minute joyrides into near-space. Yes, but technically it *could* land (and take off from) the Moon, if it were taken most of the way there by some other rocket. That's one of the advantages of a VTVL design -- they're not using anything on Earth that won't work even better on the Moon. You're getting way, way ahead of the curve. Well, I certainly agree with you there. I'd guess that Bezos has no lunar plans at the moment, and selected a VTVL design for other reasons. Best, - Joe |

It's certainly got simplicity on its side; straight up-straight down on a concrete pad is about as simple as you can get. If he can get this to work right with the final H2O2/Kerosene engines, he's got SpaceShipTwo beat all to hell in the simplicity of operations department. It's going to take some fancy trajectory work in regards to piercing the jet stream on the way up and down to get you back to exactly where you started, but in an emergency it should be able to put down safely on any flat piece of land. |
