Liftoff of #NROL52 is tentatively reset for Friday morning, But there's just a 30% chance of favourable weather as a tropical wave moves in.

The official weather forecast for Friday's launch opportunity is 30 percent favorable, primarily due to cloudy conditions.

Спойлер

"Locally, a tropical wave near South Florida will continue to usher in abundant moisture, cloudy conditions, and widespread showers over the Spaceport today and persisting through tomorrow's launch count. East- northeast winds remain breezy with a slight trend down late evening and gusting in the mid-20s during the window," the launch weather team says.

"The primary concerns for launch are cumulus clouds and thick clouds."

The forecast for the 4:03 a.m. EDT (0803 GMT) liftoff time calls for scattered and broken decks of clouds, isolated showers, good visibility, easterly winds of 20-24 knots and a temperature of 81 degrees F.

A Saturday morning launch opportunity, which has just become available on the Eastern Range, has 60 percent favorable weather.

"In the event of a 24-hour delay, the aforementioned tropical wave continues to migrate to the west with the shower potential trending down. Moisture in the mid and upper levels remains high with a thick cloud threat. The primary concern for launch is cumulus clouds and thick clouds."

A SpaceX launch originally planned for Saturday has delayed to next week for unrelated reasons, opening up a slot on the Eastern Range schedule for the Atlas, if needed.

The Range typically gives customers two launch attempts before the next rocket gets its shot, and a day between is necessary to reconfigure equipment.

A tropical wave moving through the Florida Straits continues to dump rain across a wide portion of the state today, including at the Atlas 5 rocket pad where the NROL-52 mission awaits its next opportunity to launch.

Photographers are at Complex 41 right now servicing their sound-activated cameras for another countdown tonight.

The disturbance was near the Bahamas yesterday, but is moving east-to-west into the Gulf of Mexico. A strong wind shear in the atmosphere is keeping the system from developing into a tropical storm or hurricane, but rain squalls overnight forced cancellation of the first Atlas 5 countdown and bands of showers have continued to rotate ashore all morning.

COUNTDOWN for #NROL52 now ticking to overnight Atlas 5 launch from Cape Canaveral at 4:03amEDT (0803 GMT) https://spaceflightnow.com/2017/10/02/av075_journal/ ...

10/06/2017 04:13 Countdown starts for NROL-52 launch

The second countdown begins now for the United Launch Alliance Atlas 5 rocket on the NROL-52 national security satellite deployment mission.

Спойлер

Clocks are picking up the seven-hour sequence of work that will prepare the booster, payload and ground systems for blastoff at 4:03 a.m. EDT (0803 GMT).

The launch team will start 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 GPS metric tracking system used to follow the rocket as it flies downrange, plus a test of the S-band telemetry relay system.

A planned hold begins when the count reaches T-minus 2 hours. Near the end of the 15-minute hold, the team will be polled to verify all is in readiness to start fueling the rocket for launch.

Supercold liquid oxygen begins flowing into the Centaur upper stage, followed by the first stage filling. 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. That 15-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 first weather briefing will be coming up in about 90 minutes.

10/06/2017 05:41 Weather is 40% GO

In the first weather briefing of the countdown, the weather officer has the odds at 40 percent of acceptable conditions at the 4:03 a.m. EDT (0803 GMT) liftoff time of the Atlas 5 rocket from Cape Canaveral.

Спойлер

The fierce winds experienced last night have subsided. The current ground winds at Complex 41 are just 11 knots.

The concern, however, will be showers continuing to rotate ashore that could violate the cumulus cloud rule at launch time. Moisture in the atmosphere also risks the chance of violating the rule governing the cloud thickness for triggered lightning during the rocket's ascent.

The weather reconnaissance aircraft will be airborne to interrogate the clouds in real-time.

The launch time outlook calls for scattered low-level clouds and broken mid and high cloudiness, isolated showers, good visibility, easterly winds gusting to 16 knots and a temperature of 80 degrees F.

The current weather conditions remain GO at Cape Canaveral for the Atlas 5 launch. The odds of acceptable conditions at the 4:03 a.m. EDT (0803 GMT) launch time remain at 40 percent. A cumulus cloud in the rocket's flight path is the main concern.
