What ever became of the "Big Dumb Booster" proposals?

I wish Google Mars would have taken the ESA shots instead of Nasa's as they're in color at least and seem better quality.

The Bristol Spaceplane designs look promising... have they ever been studied seriously?

Of course a refueled-in-orbit Space Shuttle can get to Lunar Orbit. That was described in an Analog article. It was then pitched to Rockwell Space Division management by a plagiarist claiming the idea as his own. Rockwell demurred, just as they did when VP Dan Quayle asked if they had anything on the drawing board like "beam me up on Star Trek." I pushed them to do an "unsolicited" white paper on teleportation, and get some quick bucks, but management was afraid the story would get out, as their "engine that never needed to be refueled" had done when pitched to Idaho National Energy Labs.
Rockwell hoped to make the big time with the cargo-only Shuttle-C I worked on that proposal), and various Manned Orbiting Vehicles and the like. They had an entire Lunar-Planetary program (to which I was assigned half-time) which dead-ended when another proven plagiarist drove out all the MIT and Caltech graduates who kept pointing out his errors (such as cubical inflatable Moonbase buildings).
The true absurdity of how the US Space program shot its feet out from under itself is too tragicomic for this blog, and I hope to novelize it someday...

The last time NASA scheduled a gap in manned spaceflight -- from Apollo/Soyuz to Shuttle -- it ran over by, oh, about five years. Just one whoopsie late in the shuttle program (after, say, 2007) and I can see them cancelling the whole thing and going straight to CEV. Which will, of course, be late. CEV is planned to do Apollo-type stuff and act as an orbital crew taxi, which is what the Shuttle ended up doing (despite being specced for a whole lot of much more ambitious stuff). So muttering about a shuttle to the moon isn't necessarily totally daft, if CEV == shuttle ... except that CEV isn't designed to deliver and retrieve KH-11s from polar orbit. Sigh. I wish ESA would just bite the bullet and upgrade ATV to full man-rated status -- all it needs is a re-entry capsule and an escape tower and it'll be the second coming of the GE Apollo design, and it's already due to launch within the next 12 months.

The ignorance on the part of whoever wrote the original article is astonishing.
Aiming to test just the first stage of the launch vehicle in 2012, with dummy upper stage and CEV is hardly a landmark. And the though that Shuttles could go to the moon?
How do you count-down in Chinese?

The current hesitations in Shuttle operations are, as with the post-Challenger interruption, apparently temporary. The gap between Shuttle and CEV looks deliberate. And it's far enough ahead that people can plan for it.
There's all sorts of reasons why not to expect a Chinese Apollo program, and a good deal of the original which was slowed by the newness of the tech and the environment--no capsule fire forcing a redesign.
But the history says that 8 years is enough time to do something big in manned spaceflight.

Betcha the CEV is overdue, over budget, and doesn't perform to spec. And we'll lose another shuttle.

Also, there seems to be an explosion of implementations happening. We have three areas: Electronics (fast chips), material (space elevator, space ship hulls), and health. This could be the greatest invention ever. Carbon is a very root pure substance as a basic building-block to all life. If you burn anything allot of it turns into carbon. It combines strongly but is easily broken apart. Diamonds have similar, very structured, carbon like properties so are the strongest (most valuable) substances known to man. The Carbon Nanotube process probably is stronger and able to be created on the fly as well as manipulated. Having control at this root level provides a large chance to construct just about anything hence infinite commercial apps. Building Blocks: http://www.ccmr.cornell.edu/education/ask/?quid=1017Interesting older article about the Diamond Age.: http://www.dse.nl/~hkl/e_nano1.htm Extremely fast circuits and computer chips being created/invented http://www.sciencedaily.com/releases/2004/01/040107072303.htmThis is known as an NED computer screen where it will consume low power, 50 watts, and will be very cheap, like 300 USDA, for an 80 inch screen maybe 50 for a 19 incher. plus flexible like the newer screens are like OrganicLED screens. It will also have the same picture quality as a tube monitor because it uses light on phosphorus as well. Funny that basic life is made of phosphorus and carbon. http://nanotechwire.com/news.asp?nid=2187&ntid=130&pg=1Kill yer cancer (safely): http://nanotechwire.com/news.asp?nid=2187&ntid=130&pg=1Yes to build large ships in space we need this type of material in their hulls. No more flying foam problem.

"I'm going into orit, I'm going into orbit!" (in sing song voice.
Killer app for sure! Something we need to make all our sfnal dreams begin, and has a good enough capitalist interest to make people pay for it!

Killer App!
I remember nanotubes in Popular Mechanics about 15 years ago but didn't know if they developed anything realistic st the time. So now it's workin and I'm still alive!

Captain, is that transparent aluminum? No, Scotty... Transparent carbon nanotube sheets createdDALLAS, Aug. 18 (UPI) -- A University of Texas at Dallas-led research team and an Australian colleague have produced strong, transparent carbon nanotube sheets. The transparent carbon nanotube sheets are stronger than the same-weight steel sheets and have demonstrated applicability for organic light-emitting displays, low-noise electronic sensors, artificial muscles, conducting appliques and broad-band polarized light sources that can be switched in one ten-thousandths of a second.... Related Headlines Study: Nanotubes may replace transistors (August 16, 2005) -- California scientists say they've found customized Y-shaped carbon nanotubes can compute more efficiently than conventional transistors.

Well, on the subject of simple things, reimplantation of removed stripes of ovarian tissue post-cancer treatment *has* been reported as leading to successful pregnancy.
