CAPE CANAVERAL, Fla. - NASA will try again on Friday to launch a Delta IV rocket from Cape Canaveral.
The mission was scrubbed Thursday night due to weather.
When the rocket gets off the ground, it will carry the first of twin satellites for the U.S. Air Force into space.
The remaining two satellites will ride an Atlas V into space next year. When completed, the satellite constellation will monitor geosynchronous satellites.
The rocket launch was also scrubbed Wednesday because of an issue with the ground support equipment environmental control system.
NASA is targeting a new window on Friday.
