The "go/no-go" poll involves several check-ins among flight controllers, weather officials and mission control.
And during the first poll, which happened about 45 minutes left on the countdown clock, weather officials gave the answer everyone wanted to hear: The forecast is looking good right now.
But things can still change. If at any time, the weather shifts and violates some of the pre-set rules for conditions, the launch could be called off.
Officials will continue monitoring the weather closely until about a minute before liftoff, when the rocket's automated computers take over.
