NASA To Retire Atlantis by 2008
SirBruce writes "As reported by Space.com, Spaceflight Now, and elsewhere, NASA is now planning to retire the Space Shuttle Atlantis by 2008, after just 5 more flghts. By doing so, they would avoid a costly and time consuming scheduled overhaul, and could still fly the remaining 12 missions (17 total) with Discovery and Endeavour, which are just now completing their ODMPs (orbiter maintenance down period). Atlantis would be kept for spare parts to keep Discovery and Endeavour flying until the shuttle program is shut down in 2010."
Sometimes old hardware isn't worth saving because it contains too many complexities, or design mistakes, to keep running.
For every DC-3 or B-52 bomber that's flying 50+ years later, there's a dozen lesser models that never made it that far. One of the success factors for these planes were their elegance -- simple but sufficient components that are easily maintained and replaced.
Unfortunately I don't think the space shuttles fit into this category. We've learned alot from them...but probably more of 'what not to do' than 'lets build 20 more!'.
I think canibalising it for parts is a good short-term move, when the program wraps up though I agree they should find a way to preserve the learnings of the shuttle program. Lets hope its replacement is safer, cheaper, and more effective!
John Maynard Keynes: "When the facts change, I change my mind. What do you do?"
...that Atlantis is the best-built of the shuttles. I work on all three shuttles, and we all know that Atlantis was the best-built one. The rate of problem reports taken on Atlantis is almost half of Discovery or Endeavor. This is a shame, but these are smart people making tough decisions...you gotta do what you gotta do.
