Have we heard a good explanation why Dragon keeps flying so 'light'? I.e. There is several thousands pounds of payload capacity, not being used.

Are they volumetrically limited? I get that they are sending back twice as much on return as launching. And that payload return is critical.

But why not launch even just water, (no more shuttle, so ISS needs all the water it can get) to fill the available mass/volume?

Great question!

Perhaps all the people asking this question might care to ask someone who can actually answer it. Call NASA, ask to speak to someone on the payload side.

Maybe it is limited by volume.

Doh! I missed your second sentence.

Ask NASA, not SpaceX. NASa says what should be on manifest.

I think it's perfectly legitimate for GeoffC to pose his question on this forum. It's uite possible that Clark has seen something that would give an easy answer.

If not, no harm no foul. No one here was suggesting that the question be directed at SpaceX.

Haven't heard any explanation from either SpaceX or NASA on how they selected the cargo. The CRS contract requires SpaceX to deliver a minimum amount in total. There's no per flight minimum. SpaceX has said they will meet or surpass the minimum cumulative amount required by the contract.

I assumed the cargo on the first flight might have been limited by volume issues but this flight also seems on the small side. Perhaps they are waiting for the greater performance and margins of the F9v.1.1.

How does one ask NASA such a question? I would if I knew how.
