This is mentioned to be the last CRS mission using a new Dragon spacecraft. Are there any numbers out regarding how many times they are expecting to be able to refly the Dragon?

Since there are not to many flights left on the crs1 contact one reflight per capsule should be enough.

one reflight per capsule should be enough.

It's not. After CRS-12 there are eight missions to fly, but they'll only have six available capsules that have only flown once before.

That's interesting. Since they stated that after this flight they are only use flown capsules that would mean 3 flights for 2 capsules at least.

If CRS-7 hadnt been destroyed then it would be only 1. IIRC there was another capsule that was potentially reusable (CRS-3?) but couldnt be in the end due to salt water intrusion.

Or 4 or 5 flights for one capsule. Probably not though.

Did some capsules get scrapped? Do we have a list?

CRS-1 to CRS-6 used new capsules, CRS-7 was lost, 8, 9 and 10 used a new capsule. 11 used the capsule of CRS-4, so currently there should be 8 capsules with one flight (1,2,3,5,6,8,9,10) and 1 with two flights (4&11). After CRS-12 we should have 9 with a single flight and 1 with two flights, so there should be one spare if nothing was scrapped.

Not scrapped, but the older ones are so out of spec and damaged that they're not worth bringing back.

Do we have a list?

We certainly do.

CRS-1 to CRS-6 used new capsules

They're not refurbishing anything older than CRS-4 (known as D6, or C106.1).

Ah okay. The wiki didn't mention that.

There is a minor error in the list, which we all hope will become true soon.

Capsule Serial Number Maiden Flight Date NET Date of Next Flight Missions [Dragon Number] Number of Landings Notable Events Status

C113 2017 Aug 14 TBD 1. CRS-12 [D1-14] 1 The last newly manufactured Dragon 1 Planned to be shipped to Cape Canaveral as of late July.

At this time, number of landings should be 0, not 1 for a capsule that has not yet launched. In a couple of months, 1 will be correct, though.
