Так мы летим или не летим? После АВД ракету надо снимать а двигатели перебирать или нет?

Так ведь не было АВД. Двигатели  не запускались, а огонь, который было видно - это дожигатели водорода.

Опс! А мне показалось что было водородное пламя...  :oops:

[Чебурашка]

А мне показалось, что и теплоизоляция на самой ракете начала гореть.

Там вроде сделали негорючую теплизоляцию?

И тишина...

Последние данные, которые были -- возможный перенос запуска на 12 декабря, а уже 13 число.

Не знаю откуда чел (steven) черпал инфу, но ещё 11 числа заказчик, провайдер пуска и полигон не определились с датой нового пуска

Hey launch fans! The team at NRO, @ulalaunch , and @30thSpaceWing continue to work through the steps necessary to establish a new launch date for #NROL71 following last week's scrub. We'll announce once available, so check back with us often for updates and new launch details.

United Launch Alliance chief executive Tory Bruno has said Saturday night's abort was caused by a "bad sensor" that tripped an automatic limit, leading the computer controlling the countdown to halt the launch just before ignition of the Delta 4-Heavy's RS-68A main engines.

"An intermittent signal from a bad monitor caused an automated hold to be triggered ... before ignition," Bruno tweeted.

The timeline to recover from the abort and reschedule the launch for Tuesday, Dec. 18, is driven by inspections of the rocket and corrective actions, Bruno said.

Counting down to launch! L-3 and everything is progressing towards launch of the #DeltaIVHeavy carrying #NROL71, planned for 12/18 at 5:57pm PST from Vandenberg AFB. The current weather outlook shows 20% chance of favorable conditions for launch. @NatReconOfc @30thSpaceWing

ULA: Delta IV-Heavy launch with NROL-71 on Tuesday "remains a 20 percent chance of favorable weather conditions for launch."

"Primary concerns: Ground Winds."

Dec. 17 -- LRR completed

The Launch Readiness Review at Vandenberg Air Force Base in California today culminated with officials giving a unanimous "go" for liftoff of the United Launch Alliance Delta IV Heavy rocket on the NROL-71 mission for the National Reconnaissance Office on Tuesday.

The launch is scheduled for 5:57 p.m. PST (8:57 p.m. EST; 0157 UTC).

"We are proud to launch this critical payload in support of our nation's national security mission," said Gary Wentz, ULA vice president of Government and Commercial Programs. "As the nation's premiere launch provider, the teams have worked diligently to ensure continued mission success, delivering our customer's payloads to the precise orbits requested."

Weather forecasters from the Air Force's 30th Weather Squadron predict gusty ground winds and a 20 percent chance of favorable conditions for the liftoff, with a few high-level clouds, northerly winds at 16 to 22 knots, gusting to 32 knots and a temperature near 60 degrees F. The only concern for a launch weather rule violation will be winds.

Crews at Space Launch Complex 6 today have retracted the 27-story Mobile Assembly Shelter away from the rocket. This 9-million-pound structure, which moves along rails, was built in the 1980s when the pad was being prepared for space shuttle launches. It was designed to shield the shuttle from the weather during on-pad assembly of the vehicle's solid rocket boosters, external tank and mating of the orbiter. Now, it gives calm working conditions during processing of the Delta IV.

On launch day, the pad's other mobile structure will be rolled back. The 32-story, 13-million-pound Mobile Service Tower supports the work platforms that lower around the Delta IV Heavy and provide technicians complete access to the rocket, and supports vertical integration of the payload atop the launch vehicle.

United Launch Alliance will provide complete live coverage of Tuesday's countdown in this blog starting at 9:00 a.m. PST (12 noon EST; 1700 UTC). Our Live Launch Updates Blog brings you official and timely information during the Delta IV Heavy rocket's countdown with automatically-refreshing updates.

Our live video webcast also can be viewed on this page starting from L-20 minutes at 5:37 p.m. PST (8:37 p.m. EST; 0137 UTC).

At the request of our customer, live mission coverage will conclude after confirmation of payload fairing jettison, which is scheduled to occur about six minutes after liftoff.

Interesting time lapse photo of the MAS (Mobile Assembly Shelter) moving today at SLC-6 in preparation for launch tomorrow. The MAS is 27 stories and weighs 9 million pounds. We are still on track for a 12/18 launch planned for 5:57pm PST. http://bit.ly/div_nrol71

Launch day has arrived for United Launch Alliance's Delta 4-Heavy rocket, which is set for liftoff from Vandenberg Air Force Base in California at 5:57 p.m. PST (8:57 p.m. EST; 0157 GMT) tonight.

But weather conditions are expected to be a major factor in the countdown, and the official forecast calls for just a 20 percent probability of weather being acceptable for liftoff.

The primary weather worry is with ground winds at Vandenberg, a military base on the Pacific coast around 140 miles (225 kilometers) northwest of Los Angeles.

If the launch slips to Wednesday evening, conditions are forecast to dramatically improve, with an 80 percent chance of good weather.

Officials from ULA, the Air Force and the National Reconnaissance Office -- which owns the top secret spy satellite payload on-board the Delta 4-Heavy -- approved plans to proceed with a launch attempt today during a launch readiness review held yesterday.

The eight-and-a-half hour countdown is set to begin at 9:27 a.m. PST (12:27 p.m. EST; 1727 GMT), followed by the retraction of the Mobile Service Tower into position for liftoff at Space Launch Complex-6.

The Mobile Assembly Shelter, which provides cover for workers during launch preparations, rolled back away from the rocket yesterday.

Today's launch attempt comes 10 days after an abort at T-minus 7.5 seconds caused by a faulty sensor. The countdown's automated sequencer called the halt less than a second before the Delta 4-Heavy's engines were set to begin igniting.
