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 Orbit: ISS in LEO 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. SpaceX CRS-19 - Wikipedia
From SpaceX: Falcon 9 static fire test complete — targeting December 4 launch from Pad 40 in Florida for Dragon’s nineteenth resupply mission to the ISS. Weather is good for launch day: 90% go. Backup day is 80% go.
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. NASA to Broadcast Next Space Station Resupply Launch
Short article with the details: SpaceX set to launch NASA mission, make experimental second-stage flight
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.
