I want our Tech workers PRODUCTIVELY employed - breaking down frontiers, coming up with new technolgies - not nursing this 30 year space plane.
http://en.wikipedia.org/wiki/Space_shuttleWhile the shuttle has been a reasonably successful launch vehicle, it has been unable to meet its goal of radically reducing flight launch costs,
as the average launch expenditures during its operations up to 2005 accumulates to $1.3 billion <1>, a rather large figure compared to the initial projections of $10 to $20 million. The total cost of the program has been $145 billion as of early 2005 ($112 billion of which was incurred while the program was operational) and is estimated at $174 billion when the Shuttle will retire in 2010. NASA's budget for 2005 allocates 30 % or 5 billion to Space Shuttle operations. <2>
The original mission of the shuttle was to operate at a high flight rate, at low cost, and with high reliability. It was intended to improve greatly on the previous generation of single-use manned and unmanned vehicles. Although it did operate as the world's first reusable crew-carrying spacecraft, it did not improve on those parameters in any meaningful way, and is considered by some to have failed in its original purpose.
Although the design is radically different from the original concept, the project was still supposed to meet the upgraded AF goals, and to be much cheaper to fly in general. One reason behind this apparent failure appears to be inflation. During the 1970s the US suffered severe inflation, driving up costs about 200% by 1980. In contrast, the rate between 1990 and 2000 was only 34% in total. This has the effect of magnifying the development costs of the shuttle tremendously. The original process by which contractors bid for Shuttle work has also inflated overall project costs as there were political and industrial pressures to spread Shuttle work around. For instance the need for a single piece SRB design was dismissed as only one company was located close enough to the Launch site to make this viable. Morton Thiokol who secured the SRB contract are based in Utah making it necessary to have the modular design that contributed to the Challenger loss. Ironically the US aerospace mergers of the 1990s mean that the vast majority of the STS contracts are now held by only one company (Boeing).
However, this does not explain the high costs of the continued operations of the shuttle. Even accounting for inflation, the launch costs on the original estimates should be about $100 million today. The remaining $400 million arises from the operational details of maintaining and servicing the shuttle fleet, which have turned out to be tremendously more expensive than anticipated.
