Never said they *will* build a replacement.

NASA does not build spacecraft. Corporations do, and they have long since
retired the tooling to build the OV-type craft.

So you're saying that the reason that NASA aren't replacing Columbia
is that they're perfectly happy with only three shuttles, and not
because they don't have a hope in hell of getting the money to do so?

You know, I'm not so sure they do want one. Well, okay, of course they
*want* one... but barring a slight scheduling blip over the nexe couple
of years where Columbia was manifested - and everything's gone out the
window due to the standdown anyway - they pretty much had a
three-shuttle program in the cards *before* STS-107. The plan was for
Columbia to do one station flight soon, then a Hubble mission in '05,
and then sit in a hangar until ~2009; indeed, there's now debate if
these latter two missions will fly in any form.

In 1986, NASA had a full - some would say overfull - schedule, relying
on a four-orbiter fleet; today, they don't - they have a
moderately-paced schedule for a three-orbiter fleet and a very sparse
schedule for a fourth. Whilst there'll be factors which would benefit
from a fourth orbiter being present - if, say, Atlantis had an accident
in flow, you could use the "spare orbiter" to prevent too great a
slippage - these aren't major enough to warrant having a sixth orbiter
built, and I deel this is why we haven't seen NASA making loud hints
about replacing Columbia now (versus increasing OSP work).

So, anyway, that's my reading; they're not pushing to get an OV-106,
becuase they don't need one. They wouldn't get one, but I don't think
that's the only reason ;-)

I'll pipe in here to disagree with that (and support your first take).
I'd say that if you offer NASA another shuttle (for free even) they
might just turn it down. Remember back to when NASA wanted to
mothball Columbia.

There are many at NASA who will breathe a collective sigh of relief at
the final wheelstop of the very last shuttle mission.

It's kind of like the Apollo days when the LLTV had its final flight.
The longer you fly that thing, the more you're inviting a funeral.
There were too many things that could go wrong with the LLTV. All of
the close calls pointed toward future fatality. And the designed crew
escape system was not totally adequate.

In these respects, flying the space shuttle poses very similar risks.

No...I'm saying that a new shuttle can be built. It won't happen
because of the difficulties (money, retooling costs, politics, time,
requirements)...but it is a physical possibility.

Perhaps I was being a little sentimental about equating human lives over
the shuttle machine. It's been pointed out that their was nothing
special about the jobs of the lost crew that can't be replaced, and I agree.

Now, if you want to tell me that it is physically impossible to build
another shuttle, despite the difficulties, then I think that will be the
start of an interesting debate.

There was a discussion here a while back of building a Shuttle 1a,
moldline and plug compatible with the existing facilities, but
starting from a clean sheet other than those limits.
