That's basically correct, but since they re-usable, no need for makeshift

Leonardo and Raffaello have both flown multiple times.
Donatello has not flown and is not scheduled to fly.
Leonardo is scheduled to be left at the station.

...IIRC, we've only got two that are "on the shelf", and parts for a
third and a half if what I read last year on NSF was correct.
Jorge? What's the real tally on these?

Something to that effect, yes. While ISS is the "obvious" first choice for
something like CAM, I think something that doesn't "fit" with ISS, like CAM,
might be better to do as a "free flyer". Dock the thing to an ATV or HTV
and visit it in a "man-tended" mode with shuttle, Orion, Dragon, Soyuz, or

Didn't Jorge Frank state a while back that CAM had vibration issues
during operation that made it unsafe, so that's why it got dumped?
It's too bad, because it was one of the few experiments that could be
done on the ISS that would have yielded really interesting data in
regards to long term habitation of the Moon or Mars.

One can dream... I really wish the CAM would fly.

And I'm sure it wouldn't hurt to be able to return some stuff back also.
It also reduces reliance on the Russians for carrying our crew up.
(Of course one could dream about finally completing and flying the CAM. :-)

Not at all. 6 into 18 is 3. That's because the delta vee required to
get to the moon and back is 18 km/sec. To do that in six stages means
each stage must impart 3 km/sec
With a 10% structural fraction and 3.0 km/sec propellant
(hypergolic)and 3.5 km/sec propellant (jet fuel and lox) and 4.0 km/
sec propellant (hydrogen and oxygen cryogens) we have the following

I thought OM was referring to the MPLM contents, not the MPLM's themselves.
I'm sure that there is a huge list of items that NASA would like to launch
to ISS (spares, supplies, and etc.) so filling the MPLM's with useful
payload shouldn't be a problem.

True. Spare parts and extra supplies would be a good thing to stockpile on
location at ISS.
There is already a plan to leave one MPLM at ISS. I wonder if NASA has
considered modifying more than one MPLM for permanent attachment at ISS and
where it could be permanently berthed.

It's not so much that as the payload penalty you pay to launch from KSC into
ISS's much higher inclination orbit.

Yeah NASA is going to get exactly what they wanted from the beginning,
more shuttle flights, most likely till it kills again:(

ISS was designed by COMMITEE, to be all things to all people but do
NOTHING well:( but perhaps spend giga trillions as political
pork.......:(
ISS isnt in a good orbit for shuttle resupply, isnt a good
microgravity research station the peolpe moving around mess up the
experiments, isnt in a good orbit to be used for departing moon or
