A five-hour launch window opens Wednesday at 8:02 p.m. Eastern time. The exact time will depend on the weather. Current forecasts give an 80 percent chance of favorable conditions. In an update posted to Twitter at about 1:20 p.m., SpaceX said the rocket’s systems were ready for flight.
If the flight can’t launch during that five-hour time frame, SpaceX could try again on Thursday beginning at 8:05 p.m. Eastern time.
The launch will be streamed live by SpaceX on its YouTube channel, and also by Netflix on its YouTube channel. Or you can watch it in the video player embedded in our coverage here.
