Weather forecasters with the U.S. Air Force's 45th Weather Squadron are predicting an 80 percent chance of favorable conditions for the launch of a United Launch Alliance (ULA) Atlas V rocket carrying the Solar Orbiter spacecraft. Liftoff is slated for Sunday, Feb. 9, at 11:03 p.m. EST from Space Launch Complex 41 at Florida's Cape Canaveral Air Force Station. The primary weather concerns at launch time are potential violation of the cumulus cloud rule and ground winds.
Two televised briefings are planned for today:
1 to 2 p.m. EST: Prelaunch news conference.
2:30 to 3:30 p.m. EST: Science briefing.
