Weather continues to look good and the 90 percent “go” prediction remains in effect, according to Launch Weather Officer Mike McAleenan of the 45th Weather Squadron.
“We are ‘go’ on all range weather and Falcon 9 weather criteria,” McAleenan told controllers during a briefing that began one hour before liftoff time. “Just a 10 percent chance of Thick Cloud Rule violation.”
The forecast calls for scattered clouds and good visibility, with a temperature of about 50 degrees F at the 4:47 a.m. launch time.
