The GOES-O spacecraft lifted off at 6:51 p.m. EDT on a Delta IV rocket. The National Oceanic and Atmospheric Administration's GOES-O satellite will improve weather forecasting and monitor environmental events around the world. The satellite is the second to be launched in the GOES N series of geostationary environmental weather satellites.
Approximately 4 hours and 21 minutes after launch, the spacecraft separated from the launch vehicle. The Universal Space Network Western Australia tracking site in Dongara monitored the spacecraft separation.
On July 7, GOES-O will be placed in its final orbit and renamed GOES-14. Approximately 24 days after launch, Boeing Space and Intelligence Systems will turn engineering control over to NASA. About five months later, NASA will transfer operational control of GOES-14 to NOAA.
