Orbital Flight Test-2 Starliner, Atlas V Roll Return to Launch Pad

This morning, Aug. 2, Boeing's CST-100 Starliner spacecraft and the United Launch Alliance (ULA) Atlas V rocket rolled out of the ULA Vertical Integration Facility (VIF) to return to the launch pad at Space Launch Complex-41 on Cape Canaveral Space Force Station in Florida ahead of NASA's Boeing Orbital Flight Test-2 mission to the International Space Station. Liftoff is scheduled for 1:20 p.m. EDT on Tuesday, Aug. 3.

Starliner and the Atlas V rocket made the first trip to the launch pad on July 29, but rolled back to the VIF on July 30 to avoid potential inclement weather.

For a launch Tuesday, meteorologists with the U.S. Space Force 45th Weather Squadron are predicting a 60% chance of favorable weather. The primary weather concerns for launch day are the cumulus cloud rule, lightning rule, and thick cloud rule violations during the instantaneous launch window.
