Jessica talking about Static Fire issues.

Sensors on Stage 1 detecting a small LOX leak. Inspection and repair occurred. Took a couple days. That static fire occurred on Friday.

Jessica going through the process of getting the Dragon ready and certify the Dragon for three flights. Everything is certified for 4x times longer than will be needed (e.g., if a tank needs to be pressurized 30 times over three flights, its certified for 120 pressurization cycles).

to add

Starting with CRS-21 ( CRS-2 contract) the capsule will land in the Atlantic and processing and refurbish will be done in Florida resulting in faster turn around for next launch.

The ~~Crew Dragons~~ Cargo Dragon 2 will be certified for 5 flights a piece. They will NOT have the SuperDraco abort system.

Nominal plan is to have all Dragon2 cargo missions for CRS2 go from 39A. Can go from 40 if needed in a pinch.

Jessica confirms that all cargo Dragon2s are ONLY for cargo and WILL NOT be used for crew flights first.

And video about Crew Dragon Cargo missions from 39A and SLC-40:

Falcon 9 and Dragon are poised to launch the CRS-18 mission to the International @Space_Station at 6:24pm EDT today, although poor weather conditions around Cape Canaveral are a concern.

This is the second flight of this Falcon 9 booster, and third flight of this Dragon capsule!

More great photos, including nice shot of 2nd stage with the grey band

CRS-18 is ready for launch, provided the weather holds! T minus 0 for the instantaneous launch window is 6:24:30 EST.

Range is not working any weather issues that would prevent pre-flight pressurization and helium work.

AFTS checks in work.

from SFN, the detached anvil cloud rule is currently NO-GO, plenty of time to clear though.

ChrisGebhardt · « **Reply #75 on:** 07/24/2019 08:51 pm »

And all weather now observed "GO".

ChrisGebhardt · « **Reply #76 on:** 07/24/2019 09:06 pm »

Technically, all is going very well. All steps are being ticked off on time to support launch today.

ChrisGebhardt · « **Reply #77 on:** 07/24/2019 09:14 pm »

T-70mins. All still progress. There are currently (as I type this, no guarantee that won't change as soon as I hit "post") no weather issues at this time.

ChrisGebhardt · « **Reply #78 on:** 07/24/2019 09:24 pm »

T-60mins. From a technical standpoint, all is well. There is, however, a troublesome shower band tracking toward the space port that is predicted to be here about 15mins before launch time... if it doesn't dissipate. #SpaceX #Falcon9 #Dragon #NASA #CRS18
