All times are in EDT unless otherwise stated.

The Virtual Launch Control Center was activated at 4:00 a.m. EDT.

The Virtual Launch Control Center was deactivated at 7:45 a.m. EDT. Thank you for joining us for NASA's online launch coverage of NOAA-N!

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?
