7:45 a.m. - 1 hour and 24 minutes since liftoff and all systems are performing nominally. The spacecraft appears to be in a near-perfect orbit!

7:44 a.m. - Data has been received that confirms deployment of NOAA-N's power-generating solar arrays.

Did You Know?
The NOAA-N satellite is equipped with a Search and Rescue transponder to relay emergency locator transmitter signals received from the ground.

7:27 a.m. - We have spacecraft separation of NOAA-N from the launch vehicle!

7:23 a.m. - SECO II is confirmed after re-ignition of the engine.

7:20 a.m. - These two stations will provide data of the re-start and burn of the second stage; Malindi will also confirm spacecraft separation.

7:19 a.m. - We have switched to the Malindi Tracking station in Kenya and have confirmation that they are now receiving NOAA-N's signal.

7:13 a.m. - The spacecraft telemetry lab has reported that we have reacquired a signal from the spacecraft.

7:11 a.m. - 48 minutes and 38 seconds since liftoff. We are standing by to receive spacecraft communications via the Hartebeesthoek tracking station in South Africa.

Did You Know?
NOAA polar operational environmental satellites collect global data on cloud cover; surface conditions such as ice, snow, and vegetation; atmospheric temperatures; and moisture, aerosol, and ozone distributions.
