After a readiness review Wednesday morning, the Air Force and United Launch Alliance have given a “go” to proceed with an 8:40 p.m. Thursday launch from Cape Canaveral of a Delta IV rocket carrying a new Global Positioning System satellite.
The forecast continues to call for an 80 percent chance of favorable weather during a 19-minute window at Launch Complex 37.
A 330-foot service tower will roll back from the rocket Thursday morning in advance of fueling operations, Local 6 News partner Florida Today reported.
Atop the 206-foot rocket is the fifth of the newest generation of GPS “IIF” satellites built by The Boeing Co.
The GPS IIF-5 spacecraft is the first of three slated for launch over the next five months to replace older members of the GPS constellation, which has 31 active spacecraft.
The launch would be the Cape’s third this year, following one each by a SpaceX Falcon 9 and ULA Atlas V.
