How much more cargo mass are they taking up this time than on the demo flight?  I assume they will have confidence to fly with less  margin this time?

Does anyone know how much extra prop was left at the end of the Demo mission?

They seemed limited by hypergols on dragon due to the extended mission which may have been the limiting factor for mass rather than F9 capabilities. Initially they spoke about having carry ons during this mission which suggests they had extra upmass capability. Just a thought.

If they only do the one test flight, does NASA get an extra CRS flight in under the existing contract?  Or does that flight just get dropped?

COTS and CRS are separate contracts. All that would happen is flight hardware for C3 would become SpX-1. Othwerwise there would be no incentive for SpaceX to combine the flights in the first place if NASA instead just got an extra CRS flight.

No.

1.  NASA did not pay for a flight under COTS.  It paid for certain milestones and data whose cost were much less than a whole flight

2.  Since COTS 3 milestones were met with the COTS 2 flight, Spacex would get paid for those milestones without having to expend a vehicle.

F9V1.1 has yet to be flown.  Would NASA put expensive cargo on an untested launcher?


Doubtful that the CRS contract gives NASA any say with regards to the LV. SpX has to deliver the cargo in order to get paid, so if F9 v1.1 unzips then it's a matter for the underwriters. SpX would then have to decide to refly v1.1 or go back to v1.0, but regardless they have to meet their upmass obligations under CRS in order to get paid. Miss enough and the customer walks.

Ah...this clears it up nicely.  Thank you!

Was the Cots2+ cargo in the contract, added for free or is SpaceX getting extra for the delivery?

They got around ~$10 million for the C2+ cargo delivery. That agreement was bundled with the supplemental COTS milestones.

Imaging that forthcoming Progress M-15M docking would have success. How do you think if it's teoretically feasibly to make any agreement between Roscosmos and NASA to downmass KURS-NA internal equipment onboard Dragon CRS SpX-1 in case such a need arises to analyse system malfunction?

The Kurs-NA troublesome equipment is already on the Progress. Unless they can actually dock again, and assuming that Kurs-NA is not needed for un docking, and assuming that the cosmonauts have the necessary tooling, and the problem is with equipment inside the pressure cabin, then yes, it could be done. I seriously doubt it will be done.

In the Live: Progress M-15M undocking & redocking thread it was stated that the now successful hardware has been removed "for future return".  Since most of the download will be by Dragon, and useable stuff clears as much space as trash which will be shipped down, the KURS hardware may come down on Dragon.

edit: but not necessarily on CRS-1
(The above discussion is not really about CRS-1 the topic of this thread.)

What kind of wastrels would dump a perfectly good booster in the ocean after just one use?

It is noted that we are half-way from the May 22 launch of COTS-2+ to the currently listed and relatively stable Oct 5 scheduled launch date of CRS-1.  Yet no photos of new hardware at the Cape, the CRS-1 Dragon, launch preps, cargo, anything (unless I missed it.)

Nothing that I know of, maybe L2 has some info?

Unfortunately not. But it's still worth every penny!

I did hear unofficially that the Dragon is just about ready for shipping. Second stage is likely at the Cape already.

They showed both stages already at Hangar AO at the time of the C2+ launch?

From that picture, it looked like some stuff still remained to do at the HIF - Applying insulation and decails to the skin as well as the fairing around the thrust structure on the core.

Of course Dragon would be the pacing item for CRS-1, considering many of it's systems had their 1st live run ending June 1st.  I honestly would be shocked it any component was signed off on for CRS-1 till COTS2/3 was sitting on the floor at Hawthorne in 1000 pieces & every piece of data was gone over 3-4 times.

If they are almost ready to ship CRS-1 to the cape I count that as a pretty fast turn around.
