The countdown for the GOES-P Geostationary Operational Environmental Satellite aboard the Delta IV is at T-minus 30 minutes at 3:33 PM Phoenix time prior to a built in hold.

You can follow along with the launch on NASA-TV.

Patrick Air Force Base has published their Launch Hazard Area warning for the Delta IV launch. We note the $250,000 fine for violating the space.

Weather briefing at 3:40 PM indicates clear skies, winds from 10 to 15 knots at the launch site and no upper atmosphere conditions that would cancel the launch.

GOES-P is the third in the current series of GOES satellites (GOES N-O-P) and will be commissioned as GOES-15 once in its geostationary orbit. Its designed lifetime is seven years, with fuel for as much as ten years if the lifetime is exceeded. The next generation will be the GOES-R series, scheduled for deployment beginning in 2014.

We are currently at T-minus 10 minutes at 3:53 PM Phoenix time prior to the built in 15 minute hold at T-minus 5 minutes.

At 3:58 PM, the launch director has announced the hold at T-minus 5 minutes. Systems are checking off items required for internal power. Weather has reported that upper levels winds are green for the first ten minutes of the launch window.

L-minus 15 minutes. Launch weight is 733,000 pounds. Total LOX is 45,500 gallons and total LH2 is 120,000 gallons. The GOES-P satellite weighs 7,005 pounds.

Final poll of all systems, prior to resuming the count, will occur at L-minus 10 minutes (4:08 PM Phoenix time).

There are three items not ready, and one red alarm being evaluated, The poll has been suspended. The launch count will not resume until these have been cleared. There is currently no estimate on resumption of the countdown.

Weather now reports upper level winds are red, and the earliest resumption of the launch countdown would be 4:42 PM Phoenix time with launch at 4:47 PM.

Launch crew is reloading software for upper level wind conditions and targeting a launch somewhere between 4:47 and 4:51 PM Phoenix time.

Latest report shows earliest T-0 at 4:57 PM Phoenix time

The alarms have now been researched. They are all single events with no re-occurrence. Recommendation to remove the flags and that has been confirmed.

L-18 minutes at 4:39. Resuming polling at L-10 minutes. Spacecraft remains on internal power and that is satisfactory.

Weather confirms the upper level winds are green. Go for 4:57 launch.

Polling of all systems prior to resuming the countdown has begun at L-10 minutes. So far all systems are green.

And all systems are green. We are now 7 minutes from launch.

The countdown has resumed.

The Delta IV has gone on internal power. Second stage on internal power. T-minus 4 minutes. Vehicle ordnance is armed (range safety can blow it up). T-minus 3 minutes. T-minus 2. Range Go for launch. T-minus 1.

Launch was successful. Boosters separated. First stage burn complete and second stage ignited at 5 minutes into the flight.

The flight has been nominal so far. Second stage shut down slightly before 14 minutes into the flight. The second burn is coming up at 22 minutes into the flight. Ignition, and operation is nominal. The second burn terminated at 27 minutes into the flight. Velocity is 31,000 feet per second. The coast phase will last 3 hours 43 minutes.

Final maneuvers will leave GOES-P in a geostationary orbit 22,236 miles above the Earth.
