Successful launch December 5, 2019 at 12:29pm EST (17:29 UTC) on Falcon 9 (new booster 1059) from SLC-40 at Cape Canaveral. ASDS landing was successful. This Dragon was previously used for CRS-4 and CRS-11.

The NSF article says this will be the third flight of the first stage from SpX-17 and SpX-18, so B1056.3.

"Moreover, as confirmed by NASA back in May, with the successful landing of this booster, NASA will proceed forward with using it for a third time on the CRS-19 mission coming up later this year – marking the first time NASA and the U.S. government reuses a Falcon 9 first stage for the third time."

EMU No. 3003 will go down and which EMU will go up?

The change of the EMU´s is planned on SpX-18

One EMU (#3003) did have a minor issue with a suit pressure sensor during EVA #52 and is being held in “ready spare” status until it is replaced by SN# 3009 which is manifested on the Space-X 18 cargo flight slated for July. Additionally, a spare Fan Pump Separator Unit will be delivered on SX-18.

Is there any particular reason why SpaceX seems to be flying all CRS flights from now on B1056.4? What is the benefit, if any, to having one dedicated first stage to loft Dragon to orbit?

1. Less travel. By having a core 'dedicated' to LC-40, you eliminate most of the travel time for the booster.
2. Because they can. SpaceX in general wants to push the bounderies of booster reuse, and NASA seems to be a willing participate in their investigation.

NASA has been involved in SX's process of validating that particular booster for re-flight, and therefor has some "ownership" of the booster's history.

NASA has in the past also wanted the boosters that had flown the least demanding missions, and those happen to be mostly CRS ones

SpX-19 now TBD, was on December, 4. So I suppose, it will be moved.

Thats not how I remember it. I thought NASA wants some extensive paper trail for each booster they put a payload on. This paper trail exists for CRS missions. Now, for a new mission, any previously flown booster would technically be fine (if it is undamaged of course). But since the paper trail already exists for previous CRS missions, these boosters are used for future NASA missions. So its not the profile that defines which booster is used for NASA missions, its the paper trail.

It was both. They explicitly said at one point the profile mattered. Not sure what the current requirements are.

I thought NASA (or SpaceX) said that B1056 would make its third spaceflight during SpX-19.

They said a while ago that it might. I don't recall that being confirmed since the last flight.

They confirmed at CRS-18 that this is still the plan pending post-recovery inspections.

It looks like the Aztechsat-1 has switched from Cygnus NG-12 to Dragon SpX-19.

According to the new ELaNa schedule AzTechSat-1, SORTIE and CryoCube will be as ELaNa 25B on SpX-19, also ELaNa 28 with CIRS and Edge Cube.
