LIFTOFF! Liftoff of the Ariane 5 rocket with Helios 2B, continuing reconnaissance services European militaries.

1625 GMT (11:25 a.m. EST)
Minus-1 minute. The Ariane 5 rocket is being switched to internal power.
A fast-paced series of events leading to launch will begin at Minus-37 seconds when the automated ignition sequence is started. The water suppression system at the launch pad will start at Minus-30 seconds. At Minus-22 seconds, overall control will be given to the onboard computer. The Vulcain main engine will be readied for ignition with hydrogen chilldown starting at Minus-18 seconds. The residual hydrogen burn flares will fire beneath the Vulcain engine at Minus-6 seconds to burn away any free hydrogen gas. The cryogenic fueling arm is also retracted at Minus-6 seconds.

At Minus-4 seconds, onboard systems take over and the two inertial guidance systems go to flight mode. The rocket's navigation, guidance and attitude control functions are also activated. Vulcain main engine ignition occurs at Minus-0 seconds with checkout between Plus+4 and Plus+7 seconds. If there are no problems found, the solid rocket boosters are ignited at Plus+7.0 seconds for liftoff at Plus+7.3 seconds.

1624 GMT (11:24 a.m. EST)
Minus-2 minutes and counting. The Vulcain engine supply valves are being opened, and the ground valves for engine chilldown are being closed. Electric heaters for the rocket's batteries and the Vulcain ignition system are being turned off.

1623 GMT (11:23 a.m. EST)
Minus-3 minutes and counting. The scheduled launch time has been loaded into the rocket's main computer system. The main stage tank pressures should also now be at flight level.

1622 GMT (11:22 a.m. EST)
Minus-4 minutes and counting. Pressurization is now underway for the main cryogenic stage's liquid oxygen and hydrogen tanks. Also, final pyrotechnic arming is starting.

1621 GMT (11:21 a.m. EST)
Minus-5 minutes and counting. Nothing is standing in the way of liftoff at 1626 GMT.

1620 GMT (11:20 a.m. EST)
Minus-6 minutes and counting. Liquid hydrogen and liquid oxygen supplies of the main cryogenic stage are being verified at flight level. Also, the pyrotechnic line safety barriers are being armed.

1619 GMT (11:19 a.m. EST)
Minus-7 minutes and counting. The synchronized sequence has started. Computers are now in control of this automated final phase of the launch countdown to prepare the rocket and ground systems for liftoff. There are three computers running the countdown -- one aboard the Ariane 5 and two redundant computers at the ELA-3 launch complex.

1618 GMT (11:18 a.m. EST)
Minus-8 minutes. One minute away from the beginning of the synchronized sequence. Everything remains green on the main status board.
Today's launch will be the 193rd launch of Europe's Ariane rocket family dating back to Christmas Eve of 1979, the 49th flight of the heavy-lifting Ariane 5 rocket, and the seventh Ariane 5 mission this year. The Ariane 5 rocket has 44 successful missions to its credit, including the last 34 consecutive flights since 2002. If all goes well this morning, this would mark the rocket's 45th success and 35th in a row.

1616 GMT (11:16 a.m. EST)
Minus-10 minutes. The status board in the Jupiter Control Center is showing all parameters remain green, indicating everything remains "go" for an on-time launch at 1626 GMT (11:26 a.m. EST; 1:26 p.m. local time). The Ariane 5 must launch on time to reach the target 420-mile-high sun-synchronous orbit for Helios 2B.
During today's mission, the Ariane 5 solid rocket boosters will burn for 2 minutes, 20 seconds before separating at an altitude of nearly 50 miles. The payload shroud covering Helios 2B will be released at Plus+3 minutes, 10 seconds.

The first stage's hydrogen-fueled Vulcain main engine will cut off at Plus+9 minutes, 36 seconds. Six seconds later, the Ariane 5 stages will separate, followed by ignition of the storable propellant upper stage at Plus+9 minutes, 49 seconds.

The upper stage will fire for more than 16 minutes, during which the rocket will fly over communications sites at St. Hubert in eastern Canada and Svalbard in Norway.

The Aestus engine will shut down at Plus+26 minutes, 18 seconds, after which the upper stage and Helios 2B will coast halfway around the world before the satellite is deployed in range of a ground station in Perth, Australia.

Spacecraft separation is slated for Plus+59 minutes, 23 seconds.

1541 GMT (10:41 a.m. EST)
Minus-45 minutes. Everything appears on track for an on-time launch at 1626 GMT (11:26 a.m. EST; 1:26 p.m. local time) from Kourou, French Guiana.
After liftoff, the 151-foot-tall rocket will roll on a northward trajectory from Kourou to traverse the northern Atlantic Ocean on the way to orbit. The Ariane 5 will be flying its first mission to polar orbit since delivering the Helios 2A satellite to space on Dec. 18, 2004.

Today is the 5th anniversary of the last Helios satellite launch.

The launch marks the final use of the Ariane 5 GS configuration developed to fill the gap in capability between the generic Ariane 5 rocket and the upgraded launcher with a cryogenic upper stage.

The Ariane 5 GS includes a storable propellant upper stage and solid rocket boosters loaded with extra propellant, an upgraded vehicle equipment bay made of composite material, and a Vulcain 1B first stage main engine.

Most future Ariane 5 missions will utilize the Ariane 5 ECA version with double payload stacks of commercial communications satellites. A specialty beefed-up configuration, called the Ariane 5 ES, will launch Europe's hefty Automated Transfer Vehicles to the International Space Station.

1526 GMT (10:26 a.m. EST)
Minus-60 minutes. The launch team should have now completed a check of connections between the Ariane 5 rocket and ground telemetry, tracking and command systems.

1456 GMT (9:56 a.m. EST)
Minus-90 minutes. Arianespace says it has resumed the final countdown for launch of the Helios 2B spy satellite for the French military.
Yesterday's launch attempt was scrubbed about five minutes before liftoff because of a technical glitch.

All reports are currently "go" for launch of the Helios 2B reconnaissance satellite atop the powerful Ariane 5 booster. At this point in the countdown, filling of the liquid hydrogen and liquid oxygen tanks should be in the topping mode.

Coming up in about 20 minutes, continuity checks between the Ariane 5 rocket and the tracking, telemetry relay and commanding systems will be verified.

Аплодисменты! :wink:

[Брабонт]

На данный момент (17 часов от времени запуска) наборов нет.

Трудно надеяться на то, что НОРАД его потерял. На втором-третьем витках спутник пересек навспасуровский барьер, так что...
Судя по времени запуска, 2B пошел в ту же плоскость, что и 2A. И кстати, спустя ровно 5 лет после 2А, день в день.

Естественно. А потом ещё и на нисходящей ветви. Может, Винду переставляют ?

[Sharicoff]

Обновляют с 3.11 до 95.  

Интересно будет, если элементы так и не появятся. Как-то сразу вспоминается история про то, как французы во время тестов своего радара GRAVES выгребли приличную охапку американских без-TLEшных аппаратов, чем вызвали недовольство вашингтонского обкома.

[Брабонт]

Так, суду всё ясно (с). Похоже, тихое возмущение французов по поводу открытых наборов на "Гелиосы" и "Эссаймы" нашло понимание у четырёхзвездных заокеанских товарищей, закрывших данные 11 дней назад (Jan 342). При этом, например, информация по бундесверовским "сарлупам" и связнику на стационаре обновляется регулярно.

 Весна придёт, набор всплывёт...

[JoJo]

Ув. Salo, мелочь, конечно, но, может, годик поправите для истории?  :wink:

Helios IIB -Ariane 5 GS (V193)- 18.12.96 19:26 ДМВ - Kourou

Исправил.

Как говорит пламенный борец с пьянством на форуме Бродяга: "Закусывать надо". :wink:

Ай да французы! Нашли видать какие-то убедительные аргументы. Элементы на Сиракузы (пока?) исправно обновляются, а Гелиосы и Эссеймы действительно придется теперь искать у Молчана.
