NASA Scraps Shuttle And Returns to Rockets 553
nathanh writes "NASA is building a launch system that they've informally dubbed Apollo On Steroids. It's a hybrid design of the Apollo capsules and the Shuttle's booster rockets and engines. Crew and cargo are lifted by two different rockets: the crew use a single-booster/single-engine rocket and the cargo is lifted by an awe-inspiring two-booster/five-engine rocket. NASA reckons this craft will take humanity back to the Moon and then to Mars. Has NASA realised that the old designs were better? Or is this all a ploy to recapture the hearts of the public?"

As too expensive, that is not accurate. The solid fuel is slightly more expensive than liquid O2/H2 systems. However, it does not require the cost infrastructure that does liquid systems. In addition, this is being used primarily to launch crew, not cargo (I suspect that the airforce will probably keep a few hanging around to launch spy sats. on a moments notice). When it comes to life, we should be (and are) willing to spend a bit more to get a better saftey record.
Now as to fragile, it is one of the most stable since it can not blow up. Now, I am sure that somebody is going to mention challenger. The solid booster did NOT blow up. It was the main liquid tank that did due to the O-ring leaking a plume into it. if we had this system in place, the leakage would have meant that those 2 segments would have had a hole and they would have been unuseable. If the hole actually got big enough, it would have meant that the capsule would have been jetisoned for crew ecscape, and everbody lives. This would have been a fraction of the costs of the challenger/columbia incidents.
At this point, the solid units are one of the best approachs at getting man into space, quickly. Long term, we will almost certainly change. In fact, I am in hopes that t/space will be a big winner.

There are examples of failed pyramids, and there is very good reason to believe that first of all, the attempted as well as the finished pyramids were substantially bigger then anything built before them (and actually, only in recent times humans built anything that would match them in size), and were pushing the limits of building technology at the time (they would have done that untill about 150-200 years ago and maybe even more recently).
So, while they did not start building them without any previous experience in stone building in general, the known number of failures, documentation and archeological evidence seem to suggest that pyramids were pretty much developed with trial and error, over a relatively short time (a few generations), and by attempting to build soemthing way beyond the known possibilities of technology at the time.

The shuttle is only good if you wish to bring stuff back down with you. In that regard you might have used it on returning to the earth. The returning spaceship could dock with the space station and transfer men and cargo to the shuttle for safe landing. But that's only saves the weight of a single heat shield.
So dropping the shuttle for a Luna and mars mission is the obvious choice. A lot of comments will be made in regard to "return to the old capsules". But this is not really relevant. The "old" capsules were a good design. The engineers for the first Luna expedition did a lot of thinking and testing before going there, so it's a good design. To come up with something new, just for the case of "making something new" would be stupid.
But these new capsules are not old! They use a new propellant, to prepare them for the mars expedition. And as the old Luna Lander had computer power equivalent to a modern average car, I'll expect the new ones will be far more advanced.
This is the same case in regards to the boosters. These are actually based on the Shuttle engines and lifters. So the engines are the same, even thou the exterior is not. And these boosters are far more advanced than the old ones as well.

If you think about automobiles, for instance, the most efficient configuration seems to be a combination of small passenger cars and large semi-trucks. The shuttle was basically an SUV: high maintenance, high cost, low gas mileage and range, and not big enough for truly heavy lifting. It was popular because it fit into the American one-size-fits-all independent mentality.
But the shuttle was also part of a natural evolution. We started out driving a Pinto. We had newfound freedom, but little useful to do with it. To take the next step required a vehicle capable of doing some serious work. But we couldn't afford to go from a Pinto to a Mack Truck. That would've been too expensive, and risky. Instead, we got a Suburban, and used it as a daily-driver, as well as for some backyard projects. The insurance was less than having two autos. There was some maintenance, but we could do it ourselves, without an expensive mechanic.
Now, though, we can afford both the Mercedes and the F-350 flatbed. We have a legitimate use for each. Eventually, we may need the equivalent of a subway car, and a Greyhound bus, and a bullet train. But even here on Earth we have lots of different ways to get around, each optimized for a specific task. We shouldn't be surprised that space is no different.

The original shuttle design was, basically, a car. It cheap, reusable, and could carry buggerall cargo. And only in some orbits.
Then NASA wanted the Army's space budget. The Army was launching some bloody huge spy satellites (the solar panels alone are pretty darn big) in a polar orbit. And they already had the rockets to launch those. If they were gonna give NASA their budget, NASA had to be guarantee they'd put those huge spy satellites up there. What the Army wanted, basically, was a truck.
So the shuttle got inflated to being big enough a truck to haul up anything that the Army could possibly want hauled up.
So here we are with a one-size-fits-all solution that makes as much sense as saying that a 10-wheeler truck is the one-size-fits-all automobile. You can drive it for anything from cargo transports to groceries to driving your kids to school, right? It has to be the perfect family vehicle, right?
In practice, that one size still didn't fit all.
For starters, now for anything smaller (e.g., a 1-2 ton satellite), packing it in a bloody huge and heavy shuttle makes as much sense as packing a half a pound Walkman in a 100 pound steel safe when shipping it by UPS. Yeah, so the safe is reusable, but you still pay entirely too much for shipping.
As a more insidious thing, it just created the problem of crew safety in a lot of situations where a crew just wasn't needed to start with. (Which, as we know, just jacked prices up even more, and made it even less attractive to use the shuttle for a lot of things. Other than as a national Our-Penis-Is-Bigger-Than-Yours status symbol.)
E.g., the army was already lifting and positioning those satellites in orbit without a crew. A computer is perfectly capable of positioning a satellite in orbit on its own. You don't need a crew of cosmonauts for that.
Using cosmonauts for that just means you have the extra worry of bringing them down in one piece, and bad PR when you don't. An unmanned rocket with a satellite exploding is something we all don't get too emotional about. E.g., you can joke about the Arianne incident and how it shows the risks of reusability, and noone will take it as insensitivity. Or about the Mars lander metric/imperial screw-up.
