This is the 3rd and FINAL Block 4 first stage / Block 5 second stage Falcon 9 configuration.

It is the first time NASA is flying with a Block 5 Falcon 9 Second Stage.

T-1hr. All quiet on the LD loop <-- a very good sign.

The extra performance of the Block 5 2nd Stage results today in a 32 second shorter ascent for orbital insertion of Dragon. CRS-14 took 9mins 03sec to reach orbit on an all-Block 4 Falcon 9. This Dragon will take only 8mins 31secs to reach orbit under Block 5 Stage 2 power.

~1 hour until Falcon 9 launch of Dragon for its fifteenth mission to the @Space_Station. Vehicle and spacecraft are healthy and tracking no issues

T-45mins and COUNTING. All continues to go well. The LD loop is very quiet. We are 10mins away from the start of Stage 1 LOX load and Stage 2 RP-1 load. Stage 2 LOX load will follow later in the count.
