United Launch Alliance scrubbed the launch of an Atlas V rocketfrom Cape Canaveral Air Force Station because an aircraft entered the launch complex's range.

The new launch window is set for Friday, 7:42 p.m. to 8:22 p.m.

The rocket was supposed to launch at 7:46 p.m. Thursday, but an instrumentation issue forced ULA to delay the launch until the end of the window, at 8:26 p.m. 

Then an aircraft entered the restricted area with minutes to go before launch.

The nearly 200-foot-tall rocket will carry a $1 billion Space-Based Infrared System (SBIRS) Geo-3 satellite into orbit for the U.S. Air Force. SBIRS is designed to provide surveillance capabilities for national security missions. The goal is to track hundreds of missile launches worldwide each year.

Once deployed, the satellite will fly in geosynchronous orbit some 22,000 miles up as it scours the planet for potential threats.

Two other SBIRS satellites, SBIRS Geo-1 and SBIRS Geo-2, were launched in 2011 and 2013, respectively.
