The launch of the Polaris Dawn mission from Cape Canaveral is now tentatively planned for very early Tuesday morning. The mission has been delayed several times, mainly due to the weather. Officials are still waiting for a weather window to launch, but the Federal Aviation Administration has now tentatively set a launch window for tomorrow, opening at 3:38am and closing at 7:09am, but that too could change. While we are not in any threat of hurricanes right now, the National Hurricane Center is tracking multiple systems that could impact the schedule, mainly the recovery areas in case of an emergency involving the crew.
