0650 GMT (2:50 a.m. EDT)
In today's first weather briefing to mission managers, all current conditions are observed GO for launch of the Atlas 5 rocket and odds for the 8:48 a.m. EDT liftoff time stand at 40 percent favorable. The main concern that meteorologists are watching is the thickness of clouds that the rocket would fly through and a slight concern about electrically-charged anvil clouds drifting over the Cape.

The outlook for the launch window now predicts scattered clouds at 2,500 feet, broken clouds at 15,000 feet and overcast conditions at 25,000 feet, good visibility, southerly winds of 10 gusting to 14 knots, a temperature of 78 degrees F and humidity level of 95 percent.

If the launch should slip to Saturday for some reason, there is a 70 percent chance of acceptable wether.

0635 GMT (2:35 a.m. EDT)
The Atlas-Centaur rocket has been powered up at Complex 41 and guidance system testing is getting started for today's launch, as the countdown progresses as planned.

0548 GMT (1:48 a.m. EDT)
The countdown begins now for this morning's launch of the Atlas 5 rocket to deploy the Navy's MUOS 2 communications satellite for mobile military users.

Clocks are picking up the seven-hour sequence of work that will prepare the booser, payload and ground systems for blastoff at 8:48 a.m. EDT (1248 GMT).

Soon the launch team will begin powering up the rocket to commence standard pre-flight tests. Over the subsequent few hours, final preps for the Centaur's liquid oxygen and liquid hydrogen systems will be performed, along with a test of the rocket's guidance system and the first stage propulsion and hydraulic preps, internal battery checks and testing of the C-band system used to track the rocket as it flies downrange, plus a test of the S-band telemetry relay system. The Complex 41 site will be cleared of all personnel at 5:53 a.m.

A planned half-hour hold begins at 6:08 a.m. when the count reaches T-minus 120 minutes. Near the end of the hold, the team will be polled at 6:35 a.m. to verify all is in readiness to start fueling the rocket for launch.

Supercold liquid oxygen begins flowing into the Centaur upper stage around 6:55 a.m., followed by the first stage filling around 7:08 a.m. Liquid hydrogen fuel loading for Centaur will be completed a short time later.

A final hold is scheduled at the T-minus 4 minute mark starting at 8:34 a.m. That 10-minute pause will give everyone a chance to finish any late work and assess the status of the rocket, payload, Range and weather before proceeding into the last moments of the countdown.

The launch window extends from 8:48 to 9:32 a.m. EDT (1248-1332 GMT).
