Planned for up to 10 flights each, but at the rate that capability is
being removed from the spacecraft to accomodate Ares I performance
shortfalls, it seems unlikely that goal will ultimately be achieved.

Assuming its not shaken to bits on the first couple of launches, I heard ten
flights. I'd have thought it might in the end be more cost effective to not
do so, and pinch individual parts for a new craft.
In other words, I think parts of it might get re used.

That's my guess. They'll do the same thing they did with the shuttle.
First flight, tear the whole thing down, rebuild, fly again.
Do that and start to realize that a craft designed for only 10 relights
really isn't all that cost-effective.
(one wonders why the Russians have never tried that with a Soyuz...)

Not sure if absolutely factual, but I was under the impression that the
russians do recycle many of the systems inside the soyuz capsule. So
while the shell is not re-used, stuff inside would be. I know that they
try to recycle the Kurs automated docking system for instance. |

You have to be a bit careful here, Brian. The Orion spacecraft's crew
module is the only part of the whole system that is (was?) expected to
be reused. The other elements, in particular the service module, is
expendable:
http://en.wikipedia.org/wiki/Orion_%28spacecraft%29
So I don't see much loss here in ditching the resusability of the crew
module, if that is indeed what is to happen.

Good question. Probably to avoid the long term costs that would be
associated with having to rebuild a new crew module from scratch and
the equipment inside it after each and every mission.

yeah they re use parts and systems. but not the outer capsule
Nasa re-used some parts of at least one Apollo Command Module, IIRC. Though
I can't point you to the reference, I recall reading a quality control
document recording/authorizing the transfer of the items from one spacecraft
to another. Some instrument panels, which had been flight-qualified, were
re-used. I recall the primary reason was that the switches had all
previously passed x-ray inspection, which was expensive enough that the
program (Skylab?) was happy to avoid the expense. Such inspections proved
necessary after in-flight incidents such as Apollo 14 wherein the LM abort
switch became a problem because of a blob of solder floating around inside
the mechanism.
I believe the ASTP docking module re-used some flown Apollo CM interior
floodlights for similar reasons. |

....Yep, along with a few panel switches that were off-the-shelf
surplus - they'd been tested and x-rayed, but not flown prior to the
DM's mission. Oddly, very little was said about this until long after
ASTP, simply because there were some "bragging issues" involved where
NASA didn't want to appear cheap in the eyes of the Russians for
recycling parts when the Russians were bragging that every part of
Soyuz 19 was a) new and b) triple-tested for "quality assurance" -
i.e., the quality goes in before the hammer & sickle goes on.
....As for the source CM of the floodlights, IIRC they came off of A16
or A17. The ones in the final version of the DM trainer reportedly
came off of A14. WRT which panel switches came from the pre-scanned
back stock, that documentation appears to either have been lost or
simply never released.

Right. Too bad they're flying with their original computers, displays,
tanks, SRBs.

I believe the docking probe from one Apollo Lunar mission was used on
another Apollo mission (I think that it had problems on the first flight, so
it was brought back for inspection as opposed to having been left with the
LM, correct me if I am wrong). Some Gemini hardware also flew on two
different Gemini missions, as well as an entire Gemini capsule on two
unmanned flights. The Skylab EVA hatch was a Gemini door, but I do not know
if it was reflown or new. |

Does it still have the window sticker in the glove compartment, and the
original spare in the trunk. That and matching numbers would increase the
resale value. |
