Launch Date: Dec 5th
Launch Window: 1730 GMT (12:30 p.m. EST)
Launch site: SLC-40 Cape Canaveral
Booster Recovery: ASDS
Booster Type: B1059.1 New

Dragon Return - 1/6/2020

A SpaceX Falcon 9 rocket will launch the 21st Dragon spacecraft mission on its 19th operational cargo delivery flight to the International Space Station. The flight is being conducted under the Commercial Resupply Services contract with NASA.

ASDS is due to an extra long booster stage burn needed to get the second stage to allow for a thermal demonstration after it drops off dragon. The pre-launch NASA briefing explains this in a video posted in this thread.

The CRS-19 mission will use a new first stage, B1059-1. B1056-3, originally penciled in for CRS-19, is now expected to be used for JCSAT, but core assignments are always subject to change. #SpaceX

Didn’t watch the NASA pre-launch video above yet but thought I’d mention that NASA would be featuring live coverage as well as SpaceX’s live coverage.

Scrubbed due to winds aloft and at the recovery ship. Try again tomorrow.

That explains the need for a new booster.

Also good details on Cargo Dragon 2; I had not seen that before. 5 missions per!

Nailed the landing. I streamed both NASA TV and the SpaceX webcast. NASA had about a one minute lag behind SpaceX. Thought NASA had slightly better camera angles and rocket booster sound transmission. Nice pop at ignition and rapid fire cracks when nearing Max Q.
