VABの扉が開きました。 通常ですと扉解放から１時間後にロケットの移動が開始されますので２０時に移動開始のようです #nvslive #H2AF33
 

The door of VAB has opened. Normally, movement of the rocket will be started one hour after the door release, so it seems to start moving at 20 o'clock

Дверь VAB открылась. Обычно движение ракеты запускается через час после отпускания двери, поэтому кажется, что она начинает двигаться в 20 часов

Ждём-с...

Japanese H-IIA rocket ready for latest IGS spy satellite launch
March 16, 2017 by William Graham
 
 

Japan's H-IIA rocket is preparing to loft the next in a series of new-generation optical imaging satellite for the country's military. The launch of latest IGS-5 spacecraft is scheduled for lift off at 10:20 local time (01:20 UTC) on Friday, setting sail from the first pad of the Tanegashima Space Centre's Yoshinobu Launch Complex.

 Japanese Mission:

The launch will carry the fifteenth spacecraft in Japan's Joho Shushu Eisei (JSE) series of satellites, commonly known in English as the Information Gathering Satellites or IGS. The IGS program, which is operated by Japan's Cabinet Satellite Intelligence Centre, consists of optical and radar imaging spacecraft.

The IGS program was initiated by Japan following North Korea's attempted launch of the Kwangmyŏngsŏng-1 satellite in August 1998; a launch which overflew Japan and raised concerns about North Korea's ability to develop a rocket capable of attacking Japan.

Спойлер

The satellites are constructed by Mitsubishi Electric and launched by Mitsubishi Heavy Industries using the H-IIA rocket.



The first pair of IGS satellites – one carrying an optical imaging payload and the other a radar imager – were launched together in March 2003. After another dual launch the same year ended in failure, IGS launches were postponed until the deployment of a lone optical satellite in 2006. A radar spacecraft followed in 2007, launching with a prototype second-generation optical satellite.

The constellation entered its second generation of satellite in November 2009 with the fourth IGS Optical spacecraft; another second-generation optical spacecraft followed in September 2011.

The radar element of the constellation has also entered its second generation, with spacecraft launching in December 2011 and January 2013. The 2013 launch also carried a prototype for the third-generation optical IGS spacecraft, the operational version of which was launched in March of 2015.
 
A further second-generation radar satellite was deployed in January in order to provide the constellation with redundancy should a satellite be lost. The need for a spare satellite arose due to the poor reliability of the first-generation radar satellites, which both failed within four years of their launches.

The latest launch carried the second third-generation spacecraft for the series, Optical 5. Taking advantage of systems demonstrated by 2013's prototype mission and the 2015 mission, the Optical 5 satellite will be used to image the Earth's surface in high resolution. The satellite is reported to have a ground resolution of approximately 40 centimeters (16 in).



For Friday's launch – which was delayed by poor weather earlier this week – the H-IIA will fly in its 202 configuration. The smallest version of the H-IIA, the 202 has been used for all of its launches since a 2009 upgrade increased its performance and rendered the now-retired intermediate 2022 and 2024 configurations obsolete.

A two-stage vehicle, the rocket consists of fully cryogenic first and second stages; fuelled by liquid hydrogen and liquid oxygen. A pair of SRB-A3 solid rocket motors provide additional thrust to the first stage during the early phases of the flight.

The rocket that will perform Friday's launch has the flight number F-33.

Departing from Pad 1 of the Yoshinobu Launch Complex, or LA-Y, at the Japan Aerospace Exploration Agency's (JAXA) Tanegashima Space Centre, the rocket will carry its payload into a sun-synchronous orbit.



The Yoshinobu Complex consists of two pads, the first of which was built for Japan's H-II rocket in the 1990s, with the second being constructed in the early 2000s as a backup pad for the H-IIA.

For this mission, the first pad will be used by the H-IIA with the second plays host to the larger H-IIB, which is used for JAXA's Kounotori resupply missions to the International Space Station.

The LE-7A engine which powers the first stage of the H-IIA will ignite two to three seconds before liftoff.

When the countdown reaches zero, the vehicle will ignite its SRM-A3 solid motors to begin the climb towards orbit. Although details of the mission profile have not been published, it is likely to follow a similar flightplan to Japan's previous launches into sun-synchronous orbits.



The solid rocket motors will burn for the first 99 seconds of the flight before their thrust tail off and they are no longer providing sufficient thrust to aid the vehicle's ascent. Hydraulic actuators will activate approximately nine seconds after the motors burn out to jettison their spent casings from the rocket.

The rocket's payload fairing also separates during first-stage flight, likely around four to five minutes after liftoff.

The first stage's fuel supply will be depleted at around the six minute, fifty seconds mark in the flight, after which the vehicle will coast until stage separation eight seconds later. Six seconds after staging the LE-5B engine of the second stage will ignite to begin its role in the launch.

Depending on mission parameters the second stage can either make a single burn with a duration of around eight minutes, or two shorter burns, to achieve the satellite's operational sun-synchronous orbit. The single-burn profile, followed shortly be spacecraft separation, is the most likely scenario.

While there were unknowns, per the parameters of the ascent, a successful spacecraft separation will be confirmed by JAXA at some point after the event occurs.

本日17日10:20に打上げ予定のH-IIAロケット33号機は0:50頃「第２回ＧＯ／ＮＯＧＯ判断会議」の結果ＧＯと判断され準備が進んでいます。 黒い段間部から白い煙が見えますので燃料充填が進んでいるようです。 写真は6時頃のロケットの様子です #nvslive
 

The H - IIA Launch Vehicle No. 33 that is planned to be launched at 10:20 today is scheduled to be judged as GO at around 0:50 and preparations are proceeding. White smoke can be seen from the black interstage, so it seems that fuel filling is proceeding. The picture shows the state of the rocket around 6 o'clock

Ракета-носитель H-IIA № 33, который планируется запустить в 10:20 сегодня, будет оцениваться как GO около 0:50, и подготовка продолжается. Белый дым можно увидеть на черном промежуточном этапе, так что, похоже, продолжается заполнение топливом. На рисунке показано состояние ракеты около 6 часов
