Launch of Delta IV Rocket with GPS IIF-9 Satellite

[Salo]

1900 GMT (3:00 p.m. EDT)
 To recap, a United Launch Alliance Delta 4 rocket was launched on-time today at 2:36 p.m. EDT carrying a new Global Positioning System spacecraft to advance the navigation network with every launch.
We will post confirmation of spacecraft separation and mission success when announced.
 
1856 GMT (2:56 p.m. EDT)
 T+plus 20 minutes. The rocket has just entered a three-hour coast period before the final engine burn to deliver GPS 2F-9 into the desired circular orbit to join the navigation network.
 
1853 GMT (2:53 p.m. EDT)
 T+plus 17 minutes. Delta has flown into a good transfer orbit.
 
1851 GMT (2:51 p.m. EDT)
 T+plus 15 minutes, 41 seconds. SECO 1. The upper stage Aerojet Rocketdyne engine has shut down after the first of two planned firings to inject the GPS spacecraft into navigation network today.
 
1849 GMT (2:49 p.m. EDT)
 T+plus 13 minutes, 30 seconds. Second stage performance still looks good.
 
1847 GMT (2:47 p.m. EDT)
 T+plus 11 minutes. Good engine controls and chamber pressure.
 
1846 GMT (2:46 p.m. EDT)
 T+plus 10 minutes. The RL10 engine is burning a mixture of liquid oxygen and liquid hydrogen cryogenic propellants.
 
1845 GMT (2:45 p.m. EDT)
 T+plus 9 minutes. Delta is 149 miles in altitude, 1,078 miles northeast of the launch pad.
