A Delta IV rocket lit up the skies over Brevard County Thursday night. The Air Force sent a new GPS satellite into orbit.
The launch was put on hold briefly during the launch window over a concern about solar radiation -- flares that could hinder communications. But those concerns were put to rest, and the rocket launched just before the window closed.
The Delta IV rocket has been under review since a problem was detected on an October 2012 rocket launch, when an engine leak caused a lower than expected thrust.
United Launch Alliance engineers said they were confident this rocket would launch without any issues.
On board the Delta IV rocket is a satellite designed to improve accuracy to GPS navigation.
"GPS 2F-5 is one of the next generation GPS satellites, incorporating various improvements to provide greater accuracy, increased signals and enhanced performance for users," said Jim Sponnick, vice president of the United Launch Alliance's Delta program.
"The GPS was initially created and designed for the military, but it also provides free, civil signal for the world to use," said Capt. Derek Reimer, Satellite Field program manager at Cape Canaveral Air Force Station. "GPS is a critical part both for the military structure and, obviously, the civilian infrastructure."
Thursday night's launch marks the 25th flight of the Delta IV rocket since its inaugural launch in 2002. Cape Canaveral has been the site for all GPS satellite launches for the Air Force since 1989.
