4 сентября, 16:22 UTC+3
Спутник оснащен оптическим оборудованием, позволяющим отслеживать возникновение атмосферных явлений, а также измерять температуру поверхности моря и выявлять содержание вулканического пепла в воздухе
ТОКИО, 4 сентября. /Корр. ТАСС Алексей Заврачаев/. Япония в ноябре этого года осуществит запуск нового метеорологического спутника "Химавари-9". Об этом сообщило Японское агентство аэрокосмических исследований (JAXA).
Аппарат обладает такими же возможностями, как и его предшественник "Химавари-8", который уже два года находится на орбите Земли. Он оснащен мощным оптическим оборудованием, позволяющим оперативно отслеживать возникновение атмосферных явлений, а также измерять температуру поверхности моря и выявлять содержание вулканического пепла в воздухе. Кроме того, он способен делать снимки Земли каждые 10 минут.
После выхода на орбиту специалисты JAXA проведут ряд проверок систем нового спутника. В эксплуатацию его планируется ввести после 2020 года, когда закончится срок службы "Химавари-8", либо это будет сделано раньше в случае возникновения неисправности у предшественника.
Информацию с нового аппарата будут получать синоптики из 30 стран Азиатско-Тихоокеанского региона (АТР). Однако, в связи с тем, что некоторые страны не способны обеспечить стабильное интернет-соединение для приема метеоданных, национальное метеорологическое управление Японии разработало систему HimawariCast system, передающую данные со спутника не напрямую, как например, в Австралию, а в сжатом виде через другие спутники.
При поддержке Всемирной метеорологической организации, Япония установила такое оборудование в Таиланде, Вьетнаме, Камбодже и ряде других государств Юго-Восточной Азии.
Специалисты отмечают, что благодаря "Химавари" в АТР значительно выросла эффективность прогнозов возникновения и движения тайфунов - одной из главных причин стихийных бедствий в этой части Земли.

A sophisticated new Japanese weather satellite will ride an H-2A rocket into orbit Wednesday to start a 15-year mission tracking cyclones and helping meteorologists predict storm movements across the Asia-Pacific and Australia.
The Himawari 9 weather observatory is set to begin its trek to geostationary orbit more than 22,000 miles (nearly 36,000 kilometers) above Earth on Wednesday from the Tanegashima Space Center, a spaceport nestled on the southern flank of Tanegashima Island in southern Japan.
Himawari 9 is the second of two identical weather satellites owned by the Japan Meteorological Agency to offer more detailed and more timely imagery of storms, clouds and other weather systems to forecasters in Japan and across the Western Pacific.
Liftoff of the 174-foot-tall (53-meter) H-2A rocket, built by Mitsubishi Heavy Industries, is set for 0620 GMT (2:20 a.m. EDT) Wednesday at the opening of a launch window that extends until 0918 GMT (5:18 a.m. EDT).
Launch is set for 3:20 p.m. Japan Standard Time, and it will take nearly a half-hour for the H-2A rocket to place Himawari 9 into an initial geostationary transfer orbit, an egg-shaped loop around Earth with a high point of 22,354 miles (35,976 kilometers), a low point of 155 miles (250 kilometers) and a tilt of 22.4 degrees to the equator.
Japanese officials delayed the launch 24 hours due to a poor weather forecast that could have prevented rollout of the H-2A rocket from its integration hangar Monday.
The weather improved Tuesday, and ground crews at Tanegashima rolled out the H-2A rocket on its mobile launch table around 1630 GMT (12:30 p.m. EDT). The 1,600-foot (500-meter) journey from the vertical assembly building to the launch pad took about 40 minutes to complete, and technicians planned to plug the launch platform into ground electrical and propellant supplies before fueling begins in the final hours of the countdown.
Once the launch team checks out the rocket's systems and loads it with cryogenic liquid hydrogen and liquid oxygen, an automated countdown sequencer will take over the final steps before liftoff.
The H-2A rocket will light its core LE-7A main engine, then ignite two strap-on solid rocket boosters to climb away from the launch pad atop nearly 1.4 million pounds of thrust.
The rocket's flight computer will command the engine and booster nozzles to pivot moments after liftoff, directing the launcher on an easterly trajectory over the Pacific Ocean.
The H-2A will exceed the speed of sound in less than a minute, then the two solid rocket boosters will consume all their pre-packed propellant at T+plus 1 minute, 38 seconds. Ten seconds later, the boosters will fall away from the H-2A's foam-covered core stage.
The two halves of the rocket's clamshell-like nose cone will peel away at an altitude of 88 miles (142 kilometers) at T+plus 4 minutes, 5 seconds, revealing the Himawari 9 satellite to the space environment.
The LE-7A main engine, producing nearly 250,000 pounds of thrust, will shut down at T+plus 6 minutes, 36 seconds, after reaching a velocity of nearly 11,000 mph (4.9 kilometers per second).
Eight seconds later, the first stage and second stage will separate, followed by ignition of the upper stage's hydrogen-fueled LE-5B engine at T+plus 6 minutes, 50 seconds. The powerplant will burn until T+plus 12 minutes, 12 seconds, to reach a preliminary low-altitude parking orbit, and then start up again at T+plus 23 minutes, 50 seconds, to climb to higher altitude.
The second LE-5B engine burn should end at T+plus 27 minutes, 7 seconds, after injecting the 7,700-pound (3,500 kilogram) Himawari 9 satellite into its intended orbit.
Deployment of Himawari 9 should occur at T+plus 27 minutes, 57 seconds, around 163 miles (263 kilometers) over the Pacific Ocean southeast of Hawaii.

Built by Mitsubishi Electric Corp., Himawari 9 will maneuver into a circular orbit nearly 22,300 miles (35,700 kilometers) over the equator a few weeks after launch.
At that altitude, the spacecraft's orbital velocity will match the rate of Earth's rotation, allowing it to hover over Asia and the Pacific Ocean to collect real-time views of clouds and storms over the Eastern Hemisphere.
Himawari 9 will be parked at 140 degrees east longitude for a mission expected to last up to 15 years. It is Japan's ninth geostationary weather observatory since the first satellite in the Himawari, or sunflower, series launched in 1977.
Japan launched the identical Himawari 8 weather satellite in October 2014, and a successful launch of Himawari 9 will allow Japan's weather agency to retire the last pair of meteorological satellites — dubbed MTSAT 1R and MTSAT 2 — that have been in space in 2005 and 2006.
Forecasters from India to Australia have been relying on Himawari 8's imagery since it entered service in 2015.
Himawari 8 and 9 carry advanced U.S.-built imaging cameras supplied by Harris Corp. The imagers can observe Earth in 16 visible and near-infrared color bands, while the previous generation of Japanese weather satellites were sensitive to five bands.
The new satellites can take a full picture of East Asia and the Western Pacific every 10 minutes, an improvement over the half-hour update times available with Japan's MTSAT weather satellites.
The spacecraft's imager can take pictures of certain areas, such as all of Japan, at even faster refresh rates — every 2.5 minutes.
There are also improvements in resolution with the Himawari 8 and 9 satellites, allowing meteorologists to see finer details at the centers of typhoons and better resolve volcanic ash and smoke plumes, fog and low-lying clouds.

T-minus 20 minutes. 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.
At liftoff, the H-2A will be propelled upward fr om 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 1.4 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, the two strap-on boosters will jettison at about the two-minute point. The 13.1-foot diameter payload shroud will separate at T+plus 4 minutes, 5 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 more than five minutes before shutting down at T+plus 12 minutes, 12 seconds.
After a nearly 12-minute coast, the second stage will reignite for a 3-minute, 17-second burn.
Deployment of the Himawari 9 satellite is expected at T+plus 27 minutes, 57 seconds.

07:35
There are 45 minutes left in today's countdown before liftoff of the H-2A rocket with Himawari 9, a Japanese weather observatory to track tropical cyclones and storms across East Asia and the Western Pacific for the next eight years.
Himawari 9 weighs about 3.5 metric tons, or approximately 7,700 pounds, at the time of launch. It was built by Mitsubishi Electric Co. in Japan.
The spacecraft is fitted with the Advanced Himawari Imager, a camera that can scan the entire disk of Earth visible to Himawari 9 every 10 minutes, an improvement from every half-hour.
The instrument, which can see in 16 spectral bands, was manufactured in the United States by Harris Corp.
Himawari 9 is the ninth satellite in the Himawari -- which means sunflower -- series of spacecraft launched since 1977.
The satellite will raise its orbit to an altitude about 22,300 miles over the equator, wh ere it will park itself at 140 degrees east longitude for an eight-year primary mission. The craft's components are designed to last up to 15 years.
Together with a sister satellite, Himawari 8, it replaces the MTSAT 1R and MTSAT 2 weather satellites launched in 2005 and 2006.

Now less than 60 minutes from the planned launch of the H-2A rocket.
Officials just gave the "go" to enter the terminal count, which began at 0520 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 and without any of the smaller strap-on boosters sometimes used to augment the launcher's thrust.
It also features a standard four-meter (13.1-foot) diameter nose shroud, which encloses the Himawari 9 spacecraft for the first few minutes of flight through the lower atmosphere.
The lead contractor for the H-2A rocket is Mitsubishi Heavy Industries.

2 ноября, 9:39 UTC+3
ТОКИО, 2 ноября. /Корр. ТАСС Кирилл Агафонов/. Японское агентство аэрокосмических исследований (JAXA) успешно запустило ракету-носитель H-IIA ("Эйч-два-эй") с метеорологическим спутником "Химавари-9" ("Подсолнух-9"). Изначально старт был запланирован на 1 ноября, однако из-за плохой погоды его пришлось перенести.
"Химавари-9" должен прийти на смену своему предшественнику "Химавари-8", срок эксплуатации которого завершится в 2020 году. До этого момента специалисты JAXA будут проводить проверки систем нового спутника. Однако, если у ныне работающего аппарата будут обнаружены неисправности, "Химавари-9" может встать в строй и в более ранние сроки.
Новый спутник, как и предшественник, оснащен мощным оптическим оборудованием, позволяющим ему оперативно отслеживать возникновение атмосферных явлений, а также измерять температуру поверхности моря и выявлять содержание вулканического пепла в воздухе. Кроме того, он способен делать снимки Земли каждые 10 минут.
