Перенос ещё на сутки.

Salo, спрошу у Вас, напоследок... Это перестраховка или ?

[Salo]

Вы на ГО посмотрите, а потом "попробуйте со всем этим взлететь"! :wink:

0015 GMT (7:15 p.m. EST Fri.)
Liftoff has been tentatively reset for next Wednesday at the earliest. That's the soonest the Eastern Range could be available to support another launch attempt. The Air Force-controlled Range provides all of the necessary tracking, communications and safety services for rocket flights from Cape Canaveral. Exactly what has the Range booked for the next few days hasn't been disclosed.
Here's the official post-scrub statement from United Launch Alliance.

"The launch of an Atlas 5 carrying the United States Navy's Mobile User Objective System 1 (MUOS 1) payload was scrubbed today due to weather conditions associated with upper level winds and flight rules associated with thick clouds. Due to lack of range availability and also the forecast weather conditions for the next several days, the Atlas 5 vehicle and MUOS will return to the Vertical Integration Facility and will roll back out to the launch pad prior to launch. The launch is rescheduled for no earlier than Wednesday, Feb. 22 from Space Launch Complex 41 at Cape Canaveral Air Force Station, Fla."

2345 GMT (6:45 p.m. EST)
Rollback has been announced. To wait on the expected several days before the Range will be available for another launch attempt, the Atlas 5 rocket will ride the rails back the third-of-a-mile to its Vertical Integration Facility to wait out the delay. Exactly when the next launch date will occur remains up in the air, but liftoff won't occur for at least the next few days.
The rollback will happen tomorrow, roughly 24 hours after the scrub to allow the vehicle to warm up from the supercold propellants that are being drained right now.

2335 GMT (6:35 p.m. EST)
If there is a prolonged wait for the next available launch shot on the Eastern Range, officials will opt to roll the Atlas 5 rocket back to its assembly building for waiting out the delay.

Народ, подскажите, а где будет стоять потом КА? Есть такая информация?

[Salo]

Видимо в одной из четырёх точек:

[Дмитрий]

))) Это понятно. Но в какой именно будет MUOS-1? Вообще если судить по траектории выведения то над Индийским океаном. То есть на 72Е. Но хотелось оффициального подтверждения

[Брабонт]

Траектория выведения почти типовая - потом уведут в рабочую точку (или в точку тестирования, в зоне видимости США?).

По траектории выведения здесь судить нельзя. Аппарат от Центавра ведь отделяется не на ГСО, а на геопереходной.

[Дмитрий]

Скорее всего точка тестирования и будет рабочей точкой... И не обязательно она должна быть в зоне видимости США.

MONDAY, FEBRUARY 20, 2012
It is looking like Friday afternoon at 5:15 p.m. EST (2215 GMT) will be the next opportunity to launch the Atlas 5 rocket carrying the U.S. Navy's next-generation mobile communications satellite.

The hoped-for Wednesday launch date was predicated on the Range becoming available quicker than expected. With that not materializing, it will be Friday before the Range can support the Atlas again.

Rollout of the mobile launch platform carrying the Atlas will occur on Thursday morning to kick off final preparations for the satellite-deployment flight. Countdown clocks begin ticking Friday at 10:15 a.m. EST.

The launch window will extend 44 minutes from 5:15 to 5:59 p.m. EST (2215-2259 GMT).

Weather forecasters, however, are predicting just a 40 percent chance of acceptable weather on Friday afternoon as another cold front slides into the local area.

"On launch day, a stronger cold front will move into Central Florida generating increasing clouds, showers and isolated thunderstorms by the afternoon. Strong southwesterly winds gusting into the low-mid 30s in advance of the front are also expected in the afternoon/evening on Friday. The primary concerns for launch are thick clouds, anvil clouds, cumulus clouds and liftoff winds," forecasters say.

The specifics call for scattered low clouds, a broken deck of mid-level clouds and overcast high clouds, rain showers and isolated storms in the area, 7 miles of visibility, southeasterly winds of 25 to 30 knots and a temperature of 73 degrees F.

If the launch should slip into the weekend, that cold front is expected to drift south of the Cape and allow the weather to improve. There's an 80 percent chance of favorable weather on both Saturday and Sunday, with only thick cloud and cumulus cloud rule concerns.

Atlas 5 rocket rolls out to pad for Friday's launch[/size]

Aiming for a third launch attempt Friday after weather conditions spoiled back-to-back countdowns last week and a previously-scheduled classified operation occupied the Eastern Range over the past several days, an Atlas 5 rocket is again standing tall on Complex 41.[/size]
