10:32
Engineers are uploading the latest upper level wind data into the H-2A's flight computer. The rocket will use the information to compute a specific steering profile based on the real launch day weather conditions.

10:30  Launch broadcast begins

JAXA's live video coverage of today's launch has begun.

10:12  Launch overview

The map above illustrates the ground track the H-2A rocket will follow after liftoff from the Tanegashima Space Center, a spaceport at the southwestern tip of the Japanese main islands.
At liftoff, the H-2A will be propelled upward from the launch pad on the power of a single hydrogen-burning LE-7A main engine and two solid rocket motors. The total liftoff thrust of the rocket is approximately 1.3 million force pounds. 
The rocket will pitch east from Tanegashima, racing through the speed of sound in less than a minute and reaching an altitude of more than 30 miles in the first two minutes of flight. 
After consuming their pre-packed solid propellant in 99 seconds, the four strap-on boosters will jettison at T+plus 1 minute, 48 seconds. The 13.1-foot diameter payload shroud will separate at T+plus 4 minutes, 15 seconds after the H-2A rocket ascends above the discernable traces of Earth's atmosphere. 
First stage main engine cutoff, stage separation and ignition of the second stage's LE-5B engine will occur nearly seven minutes into the mission. The second stage will burn for about six-and-a-half minutes before shutting down at T+plus 13 minutes, 24 seconds. 
Fifty seconds later, at T+plus 14 minutes, 14 seconds, the Astro-H spacecraft will deploy from the rocket's upper stage.
A package of secondary payloads -- the ChubuSat 2, ChubuSat 3 and Horyu 4 microsatellites built by Japanese university students -- will separate from the rocket at five-minute intervals beginning at T+plus 22 minutes, 34 seconds.

09:50  Launch statistics
Some statistics on today's launch:

[/li]
• 
  30th H-2A launch since 2001
• 
  42nd H-2 family launch since 1994
• 
  18th launch of the H-2A (202) configuration
• 
  1st launch from Tanegashima in 2016
• 
  12th space launch attempt worldwide in 2016
  

09:45  T-minus 60 minutes
Now 60 minutes from the planned launch of the H-2A rocket. 
Officials just gave the "go" to enter the terminal count, which began at 0745 GMT. The final hour of the countdown will prepare the rocket, the payloads, and ground systems for flight. 
The H-2A rocket for today's launch is flying in the "202" configuration with two large 15-meter-long (49-foot) solid rocket boosters.
It also features a standard four-meter (13.1-foot) diameter nose shroud, which encloses the Astro-H spacecraft for the first few minutes of flight through the lower atmosphere.

09:38
A second steering check of the rocket's engines has been accomplished, according to Mitsubishi Heavy Industries. 
Another "go/no go" decision point is coming up soon, before the countdown enters the terminal phase at T-minus 60 minutes. 
The Astro-H spacecraft attached atop the 174-foot-tall (53-meter) H-2A rocket is heading for an equatorial low Earth orbit on today's launch. The H-2A rocket's upper stage LE-5B engine will fire one time to accelerate the satellite into an orbit about 357 miles (575 kilometers) above Earth at an inclination of 31 degrees.

08:33  H-2A fueled for liftoff

Mitsubishi Heavy Industries, the H-2A rocket's contractor and commercial operator, reports the liquid hydrogen and liquid oxygen tanks aboard the launcher are now full of super-cold cryogenic propellant.
The next few hours of the countdown will be spent activating and checking out a variety of rocket systems, including radio frequency links with tracking stations. Another steering check of the rocket's main engine is also planned.
After testing is completed, officials will give the go-ahead for the terminal countdown scheduled to start at 0745 GMT. Liftoff remains set for 0845 GMT (3:45 a.m. EST), or 5:45 p.m. local time at the Tanegashima Space Center in southern Japan.

07:03
Slew checks of the H-2A rocket's first stage engine have also been completed earlier in the countdown, verifying the powerplant will be able to steer the launcher during ascent.
All systems remain go for liftoff of the H-2A rocket with the Astro-H astronomy satellite at 0845 GMT (3:45 a.m. EST; 5:45 p.m. Japan time).

06:53  Fueling underway

Launch officials report cryogenic propellants are being pumped into the two-stage H-2A rocket. The launcher's two stages consume liquid hydrogen and liquid oxygen propellants. Two strap-on boosters attached to the first stage are already packed with solid fuel.
The LE-7A and LE-5B engines on each stage burn the super-cold propellants during the flight. Because the propellant is stored under cryogenic conditions, it must be gradually replenished throughout the countdown to ensure proper levels of fuel are inside the rocket at liftoff.
Earlier today, the orange, black and white H-2A rocket has arrived at Launch Pad No. 1 at Tanegashima's Yoshinobu launch complex to begin preparations for fueling, including the connection of fuel lines and data and electrical cables between the ground complex and the rocket.
The 500-meter rollout from the Vehicle Assembly Building occured about 12 hours before liftoff. The trip follows rail tracks and took about a half-hour to complete.
JAXA and Mitsubishi Heavy Industries, the H-2A rocket's prime contractor, report all systems are functioning well at this point in the countdown.
Safety officials have established road blocks 3,000 meters (10,000 feet) from Launch Pad No. 1 of the Yoshinobu launch complex. The Yoshinobu launch complex was built for the H-2 rocket program that began operations in 1994 and has since been modified for use by the more powerful and H-2A rocket family.
The pads are positioned on a rocky outcrop on the southeastern flank of Tanegashima Island, which lies about 80 miles (130 kilometers) south of Kagoshima, Japan.
The complex features two pads for the H-2A and H-2B rockets. Launch Pad No. 2 has been used for five flights of the H-2B rocket with the H-2 Transfer Vehicle, an unmanned cargo ship for the International Space Station. In all, 41 rockets have departed Earth from the Yoshinobu complex since 1994. The most recent flight was an H-2A rocket launch in November 2015.

Телескоп ASTRO-H отправился в космос, сообщает JAXA

МОСКВА, 17 фев – РИА Новости. Японское космическое агентство JAXA успешно осуществило запуск рентгеновской обсерватории ASTRO-H на борту ракеты-носителя H-2A в 11 часов 45 минут, трансляция пуска проводилась в прямом эфире на сайте JAXA.

Как сообщало JAXA, спутник будет запущен с помощью ракеты-носителя H-2A номер 30 (H-IIA F30) совместно с компанией Mitsubishi Heavy Industries. Первоначальный запуск был запланирован на 12 февраля, однако он отложен до среды, 17 февраля.

С помощью таких спутников как ASTRO-H астрономы и астрофизики изучают самые "энергоемкие" и мощные процессы в космосе, невидимые для обычного глаза, например вспышки сверхновых, черные дыры или ядра активных галактик. Высокое разрешение ASTRO-H, как надеются японские физики, позволит им впервые "пощупать" пространство в окрестностях черных дыр и определить степень его искривления.

Япония ранее запустила пять рентген-астрономических спутников. Нынешний ASTRO-H, как отмечает JAXA, станет шестым по счету.
