The Non-Innovator's Dilemma
"Rand Simberg" wrote in message ... On Sun, 21 Sep 2003 15:44:25 CST, in a place far, far away, "Dholmes" made the phosphor on my monitor glow in such a way as to indicate that: I see several flaws with your argument. 1) By using development costs for the OSP vs. not including them for the shuttle you compare apples on oranges making the cost comparison worthless. Nope. I addressed that in the column. You can't compare sunk costs to avoidable ones, at least if you're trying to make a rational economic decision. When comparing 2 proposals you should always compare them equally when possible. To not do so is bad economics. By not treating them the same you set up a strawman arguement. I don't think you know what a strawman argument is. Look. You have an old car that's already paid for. You're thinking about buying another one. Keeping the old one has costs of upkeep and maintenance. Buying a new one has the cost of purchasing it. The only cost basis on which you're going to make the decision as to whether or not to buy the new one is how much it will sot you int the *future*--whether or not the payments of the new car are worth it, relative to continuing to repair and maintain the old one. You will not, unless you're insane, consider the payments that you already paid on the old one, because those are already paid, and you don't have any control over them. The basic flaw in your argument is the first car was a gift from the American people to NASA and they are willing to give NASA a second one. They want their relatives out of the 30 year old dilapidated Pinto with failing brakes that almost never runs and into a car that has a warranty and a air bag. You also fail to account for the fact that the Pinto has been proven dangerous and in the shop for extended periods of time both of which are very large costs. 4) If you are using 3 OSP flights to replace a shuttle flight and you replace at least 4 shuttle flights a year that totals 12 not 4 or 8. If you replace 6 shuttle flights then you have 18 flights. How do you figure? You can't count the cargo flights. If you are carrying it up by OSP or OSP with an attached cargo capsule then of course you count it. Even if it does not go up by OSP but replaces a shuttle flight it reduces overall costs it could be argued to count it but this is more debatable. Divide 1000 by 4 then divide 1000 by 20 the figures are radically different. But you wouldn't divide it by twenty, unless there are going to be twenty OSP flights. You will only fly OSP on those flights that require crew, and those are much fewer than cargo flights. Wrong the majority of OSP flights will probably be unmanned. If you want to take it up and bring it back it must go up on the OSP, Suyoz or the shuttle. Again it comes back to using the same figures for both. No, it comes back to using what makes accounting sense. Using real numbers always make accounting sense. 5) If they use the capsule version they will be reasonably cheap. That remains to be seen. If it is not then they have messed up big time and they should just copy the Russians or the Chinese. They've messed up big time repeatedly in the past. If by "messing up big time" means spending many billions of dollars on the OSP, they've already indicated that that's exactly what they're going to do. Always a possibility. There is no reason a private company with its own rocket could not buy an OSP. No, but there are many reasons that it wouldn't--the high costs. The Russian, American and Chinese experience with capsules say this is not the case. Really? How many private companies have bought Russian, American and Chinese capsules? Last time I checked there are several in museums and what not. Topped off with a couple of seats on actual flights. It is not the capsules that cost a lot it is the launches! If someone can lower the cost to orbit enough they can launch them cheap. Unfortunatly no one has such a cheap rocket today. That was exactly the point of the column. Then you should be proposing ways for NASA to buy rockets from private companies to increase those volumes That's a different column. I publish columns, not books. Increasing volume is IMO pretty close to the central issue. not encourage fewer such purchases. In what way did I do that? If NASA sticks with the Shuttle till it fails again that is exactly what will happen. |

The Non-Innovator's Dilemma
"Greg D. Moore (Strider)" wrote in message ... "Dholmes" wrote in message ... However, at this point, that money has been spent. So it's already accounted for. You want to count it twice. You always use the same standards when comparing two proposals. I am only trying to count each once not one 0 times and the other 3 times by adding in interest. But you're not comparing the same thing in both cases. The sunk costs for the shuttle are spent. There's nothing in the budget to account for "Original R&D" in future shuttle ops. There is such a thing as "Original R&D" for the OSP. Unlike private industry, NASA doesn't have to amortize costs after the fact. Except the American people have said they will give NASA that if it makes flights safer. Now, if you want to include FUTURE R&D costs for the Shuttle (safety upgrades, etc) that's entirely appropriate. |

Purchasing subsidized seats is not the same things as purchasing capsules. It is not the capsules that cost a lot it is the launches!

In fact I'll bet if you ask the average man on the street if he knew what the OSP was you'd get a blank stare.
