The Air Force April 10 successfully launched the National Reconnaissance Office’s (NRO) NROL-67 satellite around 1:48 p.m. EDT from Cape Canaveral Air Force Station, Fla.

The launch took place on one of United Launch Alliance’s (ULA) Atlas V rockets, which uses the Russian-made RD-180 as a first stage booster. The launch came after a 16-day delay due to an electrical short causing a tracking radar to overheat.
