I know that they are available in the Powerpoint slide, but here are some images taken from the presentation:

Is it wrong to love a cargo craft (Cygnus) more than a crew capsule (Dragon)?

With the first graphic, you really see how small the PCM is in relation to a regular MPLM (or in this case, Columbus which is a sister design, I guess PCM is like a younger cousin)

Looks (unsurprisingly?) alike ATM, doesn't it :-)

Perhaps he was trying to say ATV?

Or Apollo Telescope Mount.  That's what I thought he really meant.

Ronsmytheiii is right, I meant ATV, of course...

So if you install an ATM on the ISS, where do they spend the money ???

So Orbital has decided not to continue with their unpressurized cargo variant (or NASA has no need for it)?


NASA requested that we change the demo to pressurized and we agreed; this caused a change in the demo date.  All the details are available (I am told - I have not checked personally) in the NASA COTS web site.

And can you share with us whether you will go with the Dutch Space solar array?

That would be pointless. How could paper ever replace M&M's as the standard currency in space?  8)

Yea I hear Apple iTunes charges a $5 premium to transport the music through the tubes leading to the ISS.

[but that's enough off-topic talk]

Probably has to do with the fact that Antonio mentioned ordering 9 PCMs somewhere above on this thread.  The original SAA with Orbital was for an unpressurized demo, so if NASA bought 8 flights of pressurized on CRS it's kind of pointless to demo unpressurized.
If I like something on NSF, it's probably because I know it to be accurate.  Every once in a while, it's just something I agree with.  Facts generally receive the former.

Bingo.  Except a PCM (especially if active) costs a lot more than a UCM!

As for the milestone restructuring, it is due to the fact that changing from a UCM (which was quite advanced in design) to a PCM threw the Cygnus first flight schedule out of kilter...

You may also be interested to know that PCM's come in two "lengths": a short but light one for dense cargo, and a longer but heavier one for less dense cargo.  They also come in "active" (includes cooling at a payload mass premium) and "passive" (no cooling - more cargo) versions.

And I thought I had come up with the simplest possible system... *sigh*

But do they come in a choice of colors, like NASA blue? ;)

You can have it any color you want as long as it's white (O.K., with some gold accents here and there).

I have a quick Cygnus question for Antonio or anyone else who can field it.  I've been able to find references to what the internal volume of Cygnus is, but no data on what the actual dimensions are.  I was curious for an idea I explored on my blog today.  I could find dimensions for Dragon, but none for Cygnus. The key question would be what the usable inner diameter is.  The OD of Cygnus from the data sheets is 3.1m, I'm just not clear on how big of a diameter you could fit *inside* Cygnus.  PM me if needed.
