ULA starts it’s 2017 launch manifest

United Launch Alliance began their 2017 launch manifest with the successful delivery of the Air Force’s Space-Based Infrared System (SBIRS) GEO-3 satellite.

The launch was originally scheduled to launch yesterday but was delayed due to a sensor issue on the RD-180 engine the Atlas V 401 and then a fouled range with an aircraft encroaching on the keep out zone.

The countdown today proceeded smoothly with an on time launch occurring at 7:41 pm ET from Space Launch Complex (SLC) 41 at Cape Canaveral and delivered the payload to orbit 43 minutes later.
