2-секундное включение на полную тягу

Только что прошло  :wink:

[Зловредный]

А зачем вообще эта процедура предварительного прожига на ракете?

Складывается впечатление - для того, чтобы правильно задать все лимиты  

[Bizonich]

Да чтож такое-то, чего мне так не везет. Опять на 15 минут опоздал  :cry:
Хотя может и лучше, я пока единственную онлайн трансляцию от начала до конца посмотрел, Фобос-Грунт.

2017 GMT (4:17 p.m. EDT)
SpaceX reports the Falcon 9 engines reached full thrust for two seconds, deeming today's static fire a success.
Engineers will carefully review all data from the hotfire in the next few days before the mission's scheduled May 7 launch to the International Space Station.

2015 GMT (4:15 p.m. EDT)
Fire and smoke erupted around the base of the Falcon 9 rocket as expected, and we're awaiting results of the test.

2014 GMT (4:14 p.m. EDT)
T-minus 1 minute and counting. A steering check of the first stage engines will occur at T-minus 50 seconds, and propellant tanks will pressurize for ignition at T-minus 40 seconds.

2012 GMT (4:12 p.m. EDT)
T-minus 3 minutes and counting. The launch team is configuring the first stage's TEA-TEB ignitor system and has stopped loading liquid oxygen into the rocket in preparation for ignition.

Falcon 9 completes Static Fire Test ahead of Dragon C2/3 Launch[/size]
April 30, 2012
...
Nominal Engine Ignition was commanded by Flight Computers at 20:15 GMT and the nine Merlin 1C engines on the First Stage soared to life as turbopumps started spinning up to flight speed. Once all engines reached Liftoff Thrust, they were allowed to burn for 2 seconds before Cutoff. For a brief moment, fire and smoke erupted around the base of the Launch Pad as the engines went through their short burn.

SpaceX Conducts Falcon 9 Hot-Fire Test[/size]
By Dan Leone

    WASHINGTON — It took two tries, but Space Exploration Technologies Corp. (SpaceX) successfully test-fired all nine engines comprising the first stage of its Falcon 9 rocket April 30 in preparation for a scheduled May 7 demonstration flight in which the vehicle will launch the company's Dragon cargo capsule toward the international space station.

    "Engineers will now review data as we continue preparations for the upcoming launch," SpaceX spokeswoman Kirstin Grantham said in a statement emailed to the press after the test was completed.

    The 2-second hot-fire test took place on SpaceX's launch pad at Cape Canaveral Air Force Station in Florida. The liquid-fueled engines ignited at 4:15 p.m., about an hour later than scheduled.

    The countdown for the first attempt was halted around 3 p.m. when the "flight computer aborted [the] rocket hold down firing," Elon Musk, SpaceX's founder and chief executive, said via Twitter.

    SpaceX of Hawthorne, Calif., holds a $1.6 billion contract to fly supplies to the international space station. Before it can begin those deliveries, the company must complete a final demonstration flight in which Dragon is scheduled to approach and then berth with the station before returning to Earth.[/size]

Э, а что же там запускали? Бустеры, что ли?

Да, Шаттл целиком закрепили на стартовом столе и запустили ТТУ, запускали ли при этом главную двигательную установку я не знаю.

Интересно, по идее это именно оно и есть, об этом испытании сообщала пресса и я был совершенно уверен, что тестировали именно ТТУ.

 Непонятно тогда зачем оно вообще было нужно.

Какое интересное видео!  Я и забыл какие были страсти... Спасибо!

Next Monday's SpaceX Falcon 9 launch date in doubt[/size]

BY WILLIAM HARWOOD
STORY WRITTEN FOR CBS NEWS "SPACE PLACE" & USED WITH PERMISSION
Posted: May 1, 2012

KENNEDY SPACE CENTER, FL--The long-awaited launch of a commercial cargo ship bound for the International Space Station almost certainly will be delayed from May 7 to at least May 10 and possibly longer, sources said late Tuesday, to give company engineers additional time to complete pre-flight tests and checkout.
 
SpaceX founder and chief designer Elon Musk discussed the results of an engine test firing Monday and the overall status of launch processing with senior NASA managers in a Tuesday afternoon teleconference that included Bill Gerstenmaier, NASA's director of space operations, and Mike Suffredini, the NASA space station program manager at the Johnson Space Center in Houston.

Multiple NASA sources said the current May 7 target had been ruled out, although there was confusion in some quarters as to whether there might be a slim chance of keeping on schedule if additional analyses could be completed in time.

That did not appear likely, but NASA had no official comment on the launch date discussions because the SpaceX flight is being billed as a commercial operation and "it's up to SpaceX to make any announcements," one official said. Kirstin Brost Grantham, a SpaceX spokeswoman, had no immediate comment.

Because of test requirements and the nature of the space station's orbit, SpaceX cannot attempt back-to-back launch attempts on successive days. For this demonstration flight, attempts can only be made every third day.

For a launch on May 7, SpaceX would have a backup opportunity on May 10. After that, the company would have to stand down until May 19 or even later to make way for launch of a Russian Soyuz spacecraft carrying three fresh station crew members. The Soyuz TMA-04M spacecraft is scheduled for launch from the Baikonur Cosmodrome in Kazakhstan at 11:01 p.m. EDT (GMT-4) on May 14 with docking expected two days later.

Multiple sources said May 7 was no longer a viable launch target for SpaceX but that the company was still holding out hope for May 10. A final decision was expected by the end of the week, if not sooner.

NASA space station managers would prefer to delay the flight until after the Soyuz docking because there would be no backup opportunity if the weather or a technical problem prevented takeoff May 10 and because SpaceX would not have a second chance to dock with the station if something went awry during the rendezvous.

The SpaceX Dragon capsule is the first commercial cargo ship to be cleared for launch to the station, a key element in NASA's long-range strategy to use private-sector spacecraft to help keep the station supplied in the absence of the space shuttle. SpaceX of Hawthorne, Calif., holds a $1.6 billion contract to launch 12 resupply missions while Orbital Sciences of MacLean, Va., holds a contract valued at $1.9 billion for eight missions.

Both companies hold separate contracts for test flights and SpaceX is first to the launch pad with its Falcon 9/Dragon spacecraft.

Following a successful test flight in December 2010, SpaceX successfully lobbied NASA to combine a second and third into a single mission that would include the first Dragon berthing with the station. Launch originally was targeted for early February, but the flight has been repeatedly pushed back to give SpaceX additional time to validate its trajectory analysis and command software. Such delays are not unusual given a first flight of this complexity.

Sources said the latest slip came in the wake of recent software modifications by SpaceX that required additional verification. [/size]

Видимо, теперь уже вторая половина мая.

[Дмитрий В.]

Видимо, теперь уже вторая половина мая.

Этого хоть года-то? :wink:

[instml]

spaceflightnow.com : 7 мая под сомнением (по данным многих источников), SpaceX от комментариев воздержалась, нужны дополнительные проверки, возможная дата: 10 мая, затем 19 мая и так далее
10 мая - не самый оптимальный вариант, т.к. затруднена вторая попытка стыковки если что-то пойдет не по плану. В случае чего надо будет долго стоять на старте. Мешает Союз

[SFN]

Этого хоть года-то? :wink:

после Союза с 19 каждый третий день, исключая окна на следующие КК.

At this time a 5/7 launch is unlikely. We will issue a statement as soon as a new launch target is set.
