Up to this point, Boeing has been calling the shots for GOES-O/14, but next Friday, the reins will be handed off the NASA for approximately 5 months while it completes on-orbit checkout. The first image from the new satellite will be produced July 27. Then, the spacecraft gets handed over to NOAA, where it becomes a "hot spare," fully ready to jump in in case of a failure of one of the other GOES satellites that are currently providing the shots of the weather over the western hemisphere.
Those satellites, which are one generation older than GOES-14, are GOES-11 (or GOES-West, covering the western U.S.) and GOES-12 (or GOES-East, covering the eastern U.S.). There are two other GOES satellites floating over the Earth - GOES-10 covering South America and GOES-13, a sister to GOES-14 and also in standby mode.
