H-2A/Akatsuki launch timeline
SPACEFLIGHT NOW
Posted: May 16, 2010

NOTE: Launch sequence data assumes liftoff on May 17, 2010.
T-00:00   Liftoff
With its LE-7A main engine and two solid rocket boosters firing, the 174-foot-tall H-2A rocket lifts off from the Yoshinobu launch complex on Tanegashima Island. A few moments later, the rocket will complete a pitch program to head east from the launch site.

T+01:55   SRB-A Burnout
The H-2A's two solid rocket boosters exhaust their propellant and burn out at an altitude of 32 miles.

T+02:05   SRB-A Separation
The two solid rocket boosters are jettisoned.

T+04:19   Fairing Separation
After traversing the dense lower atmosphere and reaching an altitude of 91 miles, the rocket releases the 4-meter (13.1-foot) diameter payload fairing protecting the spacecraft during the early part of the flight.

T+06:29   Main Engine Cutoff
After consuming its liquid hydrogen and liquid oxygen propellants, the LE-7A first stage main engine shuts down. The first stage and solid rocket boosters push the rocket to a velocity of about 11,400 mph.

T+06:37   Stage Separation
The H-2A rocket's first stage is separated now, having completed its job. The spent stage will fall into the Pacific Ocean downrange from Tanegashima.

T+06:43   Second Stage Ignition 1
With the first stage jettisoned, the rocket's second stage takes over. The LE-5B hydrogen-fueled engine ignites at an altitude of 140 miles to accelerate the payloads to orbital velocity during its first of two burns.

T+11:29   Second Stage Cutoff 1
The LE-5B second stage engine shuts down after reaching its specified orbital targets. This completes the first burn of the second stage.

T+12:32   Negai Separation
The 2-pound Negai CubeSat payload will be deployed in a low-altitude parking orbit for Soka University of Japan. Negai will test an information processing system during a three-week mission.

T+12:42   WASEDA-SAT2 Separation
The WASEDA-SAT2 seconday payload separates from the H-2A upper stage. Developed by Waseda University, the 2.6-pound spacecraft will conduct technology experiments in orbit.

T+12:52   KSAT Separation
The 3.3-pound KSAT spacecraft is released from the H-2A upper stage to conduct Earth observation experiments for Kagoshima University.

T+22:53   Second Stage Ignition 2
After coasting for more than 11 minutes, the H-2A rocket's second stage LE-5B engine fires again to propel the Akatsuki spacecraft on an escape trajectory.

T+26:46   Second Stage Cutoff 2
The LE-5B second stage engine shuts down after reaching an escape trajectory at a velocity of approximately 26,000 mph.

T+27:50   Akatsuki Separation
The Akatsuki spacecraft separates from the H-2A upper stage to begin a six-month journey to Venus.

T+32:50   Begin Solar Array Deployment
Akatsuki's two solar array paddles begin deploying about five minutes afer spacecraft separation.

T+35:50   End Solar Array Deployment
The solar array paddles should be fully unfurled eight minutes after spacecraft separation.

T+36:10   Payload Attach Fitting Jettison
The payload adapter connecting the Akatsuki and Ikaros spacecraft is released, exposing the Ikaros solar sail for separation.

T+43:05   Ikaros Separation
The H-2A rocket's secondary payload, the Ikaros solar sail, separates 43 minutes after liftoff.

T+48:15   UNITEC-1 Separation
The 46-pound UNITEC-1 satellite from the Japanese University Space Engineering Consortium is deployed. UNITEC-1 will test computer technologies and broadcast radio waves from deep space for decoding by amateur radio operators.

Полчаса до пуска

У, яка цука!

По-японски что-то ближе к "акацки".

2134 GMT (5:34 p.m. EDT)
T-minus 10 minutes. The weather at Tanegashima is not ideal, with showers, low clouds and some sea fog in the area. But that should not prevent an on-time liftoff.

[Чебурашка]

Перенос из-за погоды

Today launch is cancelled

[Salo]

Пуск отложен по погодным условиям.

[smokan]

Сказали по английски что запуск отменен через погодные условия. ((

[Dude]

Жаль.  :roll:

[smokan]

И на какое число отложили запуск, интересно.

[Salo]

Пока не ясно. Должны пустить до 3 июня.

[smokan]

Завтра наверное заглавления газетных статей будет типа того:
Launch Weather satellite was canceled because of weather.  
Ничего подождем вторую попытку!

Launch Postponement of
Venus Climate Orbiter 'AKATSUKI' (PLANET-C)
by H-IIA Launch Vehicle No. 17

May 18, 2010 (JST)

Mitsubishi Heavy Industries, Ltd.
Japan Aerospace Exploration Agency (JAXA)

Mitsubishi Heavy Industries, Ltd. and the Japan Aerospace Exploration Agency would like to announce that we have decided to postpone the launch of the Venus Climate Orbiter "AKATSUKI" (PLANET-C) by H-IIA Launch Vehicle No. 17 (H-IIA F17) as we observed clouds including a freezing layer (see attachment) that exceeded the restrictions for suitable weather.

The launch was originally scheduled for May 18, 2010 (Japan Standard Time, JST) from the Tanegashima Space Center.

We will inform the new launch date as soon as it is determined.

На сайте JAXA появилась информация что запуск Акатсуки отложен на 21 мая (хотя у нас на сайте в новостях пишет что запуск отложен на сутки)

The launch of the Venus Climate Orbiter "AKATSUKI" and the Small Solar Power Demonstrator "IKAROS" by the H-IIA Launch Vehicle No. 17 was rescheduled at 6:58:22 a.m. on May 21 (Fri. Japan Standard Time, JST) after carefully studying the weather conditions.

Вторая попытка запуска намечена на 20 мая в 21:58:22 UTC.

Вторая попытка запуска намечена на 20 мая в 21:58:22 UTC.

Это по какому еще времени?
По Токио 6:58:22 a.m. on May 21, а 21:58:22  это где то наверное в Атлантическом океане за Азорскими островами ))

[Salo]

UTC это Гринвич.
21 мая в 1:58:22 ЛМВ.

[Брабонт]

Это по какому еще времени?

Осознал, исправлюсь . Привычка думать "по Гринвичу".

Ну вроде бы всё правильно, между UTC и Японией 9 часов разницы.
