Approximately 45 minutes before liftoff, audio from mission control will be available at youtube.com/spacex.

So we think it's still targeting 1150 local?
Falcon 9 and Dragon are vertical ahead of tonight’s resupply mission to the @space_station – the final mission of the first version of Dragon. Launch is targeted for 11:50 p.m. EST → spacex.com/webcast
Since its first mission in 2012 – when it became the first private spacecraft to visit the @space_station – Dragon has spent over 520 days attached to the orbiting laboratory, delivered over 95,000 pounds of cargo, and returned over 76,000 pounds pack to Earth
Diggin the backdrop for today’s press briefing - every successful CRS mission. This mission will mark the end of the first CRS contract with SpaceX. The next one will be under the new contract, using Dragon V2.
Mike: For tonight, 60% chance of GOOD weather (not including Upper Level Winds). Winds have been lower than predicted today, so Mike thinks we're actually around 70% GO for tonight (not including Upper Level Winds). #SpaceX #Falcon9 #Dragon #CRS20
Mike: Upper Level Wind shear is predicted LOW risk tonight. #SpaceX #Falcon9 #Dragon #CRS20
Hans: Last launch had a landing failure due to the winds that the booster encountered not being as predicted. Therefore, the booster decided to divert to a water landing to protect the droneship.
SpaceX has made improvements to their wind predictions since that incident.
Hans: The 2nd stage grey stripe on a past mission worked as designed to keep propellant at temperature for long-coast missions. Also, SpaceX can fly up to 3 or 4 Dragons in orbit at the same time. #SpaceX #Falcon9 #Dragon #CRS20
Hans: Ground wind limit is direction dependant but "around 34-35 mph-ish. #SpaceX #Falcon9 #Dragon #CRS20
Hans: "It's not just the upper level wind speed, it's also shear AND prediction of shear." #SpaceX #Falcon9 #Dragon #CRS20
Stunning sunset at @spacex pad 40 right now #CRS20
