Another Leak Delays Final Discovery Launch
vsolepr writes "Today's scheduled launch was scrubbed because of a gaseous hydrogen leak near the spacecraft's external tank. This is the fourth time in the past week that Discovery's launch was delayed due to various leaks and electrical issues. NASA now is aiming for a launch date no earlier than Nov. 30."
I would rather waste money on this than some of the other crazy things that the government wastes money on. Have you ever seen a shuttle launch. It lights up the sky from 90 miles away. It is kind of impressive what humans kind can do when they are not fighting against each other.
It always puzzles me why folks imagine saying a given piece of tech is old is axiomatically equivalent to saying it's been mightily improved upon since then.
Has the pencil been improved on yet? How about the wheel? Are we still burning gasoline in cylinders with pistons to power cars, like we started doing in the 1880s? Do we still use propellors to make boats move? Et cetera.
I'm not suggesting it's not possible to improve the Shuttle -- but that case has to be made in detail, not tossed off with an assumption that because it was designed in the 60s and built in the 70s there must be a far better idea. After all, the biggest advances since the 70s have mostly been in stuff like electronics or avionics, and besides the fact that this doesn't do squat for things like thermal protection and reliability of very high energy rocket systems under very heavy load (the two weaknesses that killed Columbia and Challenger, respectively) the best of these advances in electronics have in many cases been retrofitted into the Shuttle anyway.
Point me to a genuine major advance in airframe materials, thermal protection systems, or rocket engine design since the 1970s and maybe this contempt might be better supported by actual evidence.
Absolutely. But there is a world of difference between competing in a noble competition to be the first in space, vs the competition for wealth and power that is unconstrained by any sort of moral compass.
I am all for competition, but thing there should be some like drawn between just and unjust competition. Competing by creating a better product is good. Competing by creating a patent pool and suing anyone that makes a better product is unacceptable and cowardly.
Yes, I am way too idealistic.

This was the last external tank made at Michoud. As it rolled down the assembly line, everyone who worked on it did their particular task and then was laid off as soon as they were done.
And people are shocked it's not particularly well made? Frankly, I think the astronauts taking this tank into orbit have to be nuts.
I'm not in disagreement with you, but I still am really interested in knowing how much of the "cost" of launching a shuttle is amortized into the space program's sunk costs, how much is in the market value of natural resources, how much is in salaries and real estate expenses and stuff, and how much is marginal costs...
It's a few years since I looked into this, but I believe at the time the variable cost of a shuttle flight was around $250,000,000 and the fixed costs of the program were over $3,000,000,000 a year. A lot of those fixed costs go into maintaining KSC and other NASA facilities; imagine how much an airline ticket would cost if you flew a mere six times a year and did so from your own multi-runway international airport with a staff of thousands.
Taking pride on one's work died round about the time that job security and pay that wasn't "How low can we get away with?" did.
