Japan Becomes A Military Space Player With Latest Launch

The Japanese Aerospace Exploration Agency (JAXA) has accomplished some impressive things over the years. Between 2003 (when it was formed) and 2016, the agency has launched multiple satellites – ranging from x-ray and infrared astronomy to lunar and Venus atmosphere exploration probes – and overseen Japan’s participation in the International Space Station.

But in what is an historic mission – and a potentially controversial one – JAXA recently launched the first of three X-band defense communication satellites into orbit. By giving the Japanese Self-Defense Forces the ability to relay communications and commands to its armed forces, this satellite (known as DSN 2) represents an expansion of Japan’s military capability.

The launch took place on January 24th at 4:44 pm Japan Standard Time (JST) – or 0744 Greenwich Mean Time (GMT) – with the launch of a H-IIA rocket from Tanegashima Space Center. This was the thirty-second successful flight of the launch vehicle, and the mission was completed with the deployment of the satellite in Low-Earth Orbit – 35,000 km; 22,000 mi above the surface of the Earth.

Shortly after the completion of the mission, JAXA issued a press release stating the following:

“At 4:44 p.m., (Japan Standard Time, JST) January 24, Mitsubishi Heavy Industries, Ltd. and JAXA launched the H-IIA Launch Vehicle No. 32 with X-band defense communication satellite-2* on board. The launch and the separation of the satellite proceeded according to schedule. Mitsubishi Heavy Industries, Ltd. and JAXA express appreciation for the support in behalf of the successful launch. At the time of the launch the weather was fine, at 9 degrees Celsius, and the wind speed was 7.1 meters/second from the NW.”

This launch is part of a $1.1 billion program by the Japanese Defense Ministry to develop X-band satellite communications for the Japan Self-Defense Forces (JSDF). With the overall goal of deploying three x-band relay satellites into geostationary orbit, its intended purpose is to reduce the reliance of Japan’s military (and those of its allies) on commercial and international communications providers.

While this may seem like a sound strategy, it is a potential source of controversy in that it may skirt the edge of what is constitutionally permitted in Japan. In short, deploying military satellites is something that may be in violation of Japan’s post-war agreements, which the nation committed to as part of its surrender to the Allies. This includes forbidding the use of military force as a means of solving international disputes.

It also included placing limitations on its Self-Defense Forces so they would not be capable of independent military action. As is stated in Article 9 of the Constitution of Japan (passed in 1947):

“(1) Aspiring sincerely to an international peace based on justice and order, the Japanese people forever renounce war as a sovereign right of the nation and the threat or use of force as means of settling international disputes.
(2) In order to accomplish the aim of the preceding paragraph, land, sea, and air forces, as well as other war potential, will never be maintained. The right of belligerency of the state will not be recognized.”

However, since 2014, the Japanese government has sought to reinterpret Article 9 of the constitution, claiming that it allows the JSDF the freedom to defend other allies in case of war. This move has largely been in response to mounting tensions with North Korea over its development of nuclear weapons, as well as disputes with China over issues of sovereignty in the South China Sea.

This interpretation has been the official line of the Japanese Diet since 2015, as part of a series of measures that would allow the JSDF to provide material support to allies engaged in combat internationally. This justification, which claims that Japan and its allies would be endangered otherwise, has been endorsed by the United States. However, to some observers, it may very well be interpreted as an attempt by Japan to re-militarize.

In the coming weeks, the DSN 2 spacecraft will use its on-board engine to position itself in geostationary orbit, roughly 35,800 km (22,300 mi) above the equator. Once there, it will commence a final round of in-orbit testing before commencing its 15-year term of service.

NASA GODDARD SPACE FLIGHT CENTER, MARYLAND – A powerful, next generation weather observatory aimed at gathering unprecedented 3-D measurements of global rain and snowfall rates – and jointly developed by the US and Japan – thundered to orbit today (Feb. 27 EST, Feb. 28 JST) ) during a spectacular night time blastoff from a Japanese space port.

The Global Precipitation Measurement (GPM) Core Observatory was launched precisely on time at 1:37 p.m. EST, 1837 GMT, Thursday, Feb. 27 (3:37 a.m. JST Friday, Feb. 28) atop a Mitsubishi Heavy Industries H-IIA rocket from the Tanegashima Space Center on Tanegashima Island off southern Japan.

Viewers could watch the spectacular liftoff live on NASA TV – which was streamed here at Universe Today.

“GPM’s precipitation measurements will look like a CAT scan,” Dr. Dalia Kirschbaum, GPM research scientist, told me during a prelaunch interview with the GPM satellite in the cleanroom at NASA’s Goddard Space Flight Center in Greenbelt, Md.

“The radar can scan through clouds to create a three dimensional view of a clouds structure and evolution.”

GPM is the lead observatory of a constellation of nine highly advanced Earth orbiting weather research satellites contributed by the US, Japan, Europe and India.

Indeed GPM will be the first satellite to measure light rainfall and snow, in addition to heavy tropical rainfall.

It will collect a treasure trove of data enabling the most comprehensive measurements ever of global precipitation every three hours – and across a wide swath of the planet where virtually all of humanity lives from 65 N to 65 S latitudes.

GPM orbits at an altitude of 253 miles (407 kilometers) above Earth – quite similar to the International Space Station (ISS).

The global precipitation data will be made freely available to climate researchers and weather forecasters worldwide in near real time – something long awaited and not possible until now.

Water and the associated water and energy cycles are the basis of all life on Earth.

Yet scientists lack a clear and comprehensive understanding of key rain and snow fall amounts on most of the globe – which is at the heart of humanity’s existence and future well being on the home planet.

Having an accurate catalog of the water and energy cycles will direct benefit society and impact people’s lives on a daily basis with improved weather forecasts, more advanced warnings of extreme weather conditions, aid farmers, help identify and determine the effects of global climate change.

Researchers will use the GPM measurements to study climate change, freshwater resources, floods and droughts, and hurricane formation and tracking.

“With this launch, we have taken another giant leap in providing the world with an unprecedented picture of our planet’s rain and snow,” said NASA Administrator Charles Bolden, in a NASA statement.

gpm-decal-smallGPM will help us better understand our ever-changing climate, improve forecasts of extreme weather events like floods, and assist decision makers around the world to better manage water resources.”

“The GPM spacecraft has been under development for a dozen years,” said GPM Project Manager Art Azarbarzin of NASA’s Goddard Space Flight Center in Greenbelt, Md., in a prelaunch interview with Universe Today conducted inside the clean room with GPM before it’s shipment to Japan.

“The GPM satellite was built in house by the dedicated team at NASA’s Goddard Space Flight Center in Maryland,” Azarbarzin told me.

“It’s the largest satellite ever built at Goddard.”

Following the flawless blastoff, the nearly four ton GPM spacecraft separated from the Japanese rocket some 16 minutes later at an altitude of 247 miles (398 kilometers).

10 minutes later both of the spacecrafts life giving solar arrays deployed as planned.

“It is incredibly exciting to see this spacecraft launch,” said Azarbarzin, in a NASA statement. He witnessed the launch in Japan.

“This is the moment that the GPM Team has been working toward since 2006.”

“The GPM Core Observatory is the product of a dedicated team at Goddard, JAXA and others worldwide.”

“Soon, as GPM begins to collect precipitation observations, we’ll see these instruments at work providing real-time information for the scientists about the intensification of storms, rainfall in remote areas and so much more.”

The $933 Million observatory is a joint venture between the US and Japanese space agencies, NASA and the Japan Aerospace Exploration Agency (JAXA).

The 3850 kilogram GPM satellite is equipped with two instruments – an advanced, higher resolution dual -frequency precipitation (DPR) radar instrument (Ku and Ka band) built by JAXA in Japan and the GPM microwave imager (GMI) built by Ball Aerospace in the US.

The GPM observatory will replace the aging NASA/JAXA Tropical Rainfall Measuring Mission (TRMM) satellite launched back in 1997 and also jointly developed by NASA and JAXA.

“GPM is the direct follow-up to the currently orbiting TRMM satellite,” Azarbarzin explained to me.

“TRMM is reaching the end of its usable lifetime. After GPM launches we hope it has some overlap with observations from TRMM.”

GPM is vital to continuing the TRMM measurements. It will help provide improved forecasts and advance warning of extreme super storms like Hurricane Sandy and Super Typhoon Haiyan.

“TRMM was only designed to last three years but is still operating today. We hope GPM has a similar long life,” said Azarbarzin.

Powerful New Next-Gen US/Japan GPM Satellite to Revolutionize Global Precipitation Observations and Climate Science Research

NASA GODDARD SPACE FLIGHT CENTER, MARYLAND – Weather researchers and forecasters worldwide are gushing with excitement in the final days leading to blastoff of the powerful, new Global Precipitation Measurement (GPM) Core Observatory – built by NASA in a joint effort with Japan.

GPM is a next-generation satellite that will provide global, near real time observations of rain and snow from space and thereby open a new revolutionary era in global weather observing and climate science. Therefore it will have a direct impact on society and people’s daily lives worldwide.

The team is counting down to liftoff in less than 5 days, on Feb. 27 at 1:07 PM EST from the Tanegashima Space Center, on Tanegashima Island off southern Japan, atop the highly reliable Mitsubishi Heavy Industries H-IIA rocket.

The GPM launch to low Earth orbit was delayed by both natural and manmade disasters – namely the 2011 Fukushima earthquake in Japan as well as the ridiculous US government shutdown in Oct. 2013. That’s the same foolish shutdown that also delayed NASA’s new MAVEN Mars orbiter and numerous other US space & science projects.

Shortly after my tour of GPM, the 3850 kilogram satellite was carefully packed up for shipment to the Japanese launch site.

“GPM will join a worldwide constellation of current and planned satellites,” Azarbarzin told me during an interview in the Goddard cleanroom with GPM.

gpm-decal-smallAnd the imminent launch to augment the existing satellite constellation can’t come soon enough, he noted.

It is vital to continuing the TRMM measurements and will help provide improved forecasts and advance warning of extreme super storms like Hurricane Sandy and Super Typhoon Haiyan, Azarbarzin and Kirschbaum explained.

Researchers will use the GPM measurements to study climate change, freshwater resources, floods and droughts, and hurricane formation and tracking.

“The water-cycle, so familiar to all school-age young scientists, is one of the most interesting, dynamic, and important elements in our studies of the Earth’s weather and climate,” said John Grunsfeld, associate administrator for NASA’s Science Mission Directorate in Washington, in a statement.

“GPM will provide scientists and forecasters critical information to help us understand and cope with future extreme weather events and fresh water resources.”

Japan blasts the White Stork Kounotori to Space Station

[/caption]

A Japanese rocket successfully blasted off early this morning (Jan. 22) on a vital mission bound for the International Space Station (ISS). The launcher carried the Kounotori2 – which means ‘White Stork’ in Japanese – cargo resupply vessel. Kounotori2, also dubbed HTV2, is stocked with over 3800 kilograms (8000 pounds) of crucial science experiments, research gear, food and provisions for the six person international crew living aboard the Earth orbiting outpost.

Liftoff of the unmanned H-IIB rocket from Launch Pad No. 2 at the Tanegashima Space Center occurred earlier today at 2:37:57 p.m. on January 22, local Japan Standard Time (12:37:57 a.m. EST), from a remote island rocket base located in southern Japan.

Watch 2 Videos of the launch below. Especially be sure to view the Japanese version (interspersed with English) which captured dramatic rear-looking video of the receding Earth and its curvature and the separation of the Solid Rocket Boosters (SRBs) – during the ascent to orbit.

The launch was flawless in all respects. The Japanese Space Agency – JAXA – confirmed that the Kounotori2 cargo carrier separated from the launch vehicle as expected at about 15 minutes and 13 seconds after liftoff.

Blast off of the 186 foot tall rocket had been delayed two days by poor weather. By the time of Saturday’s launch, the weather had cleared with a wind speed of 8.3 meters/second from the north-west and the temperature was 10.6 degrees Celsius according to JAXA.

The H-IIB is a two-stage rocket powered by liquid oxygen and liquid hydrogen with four strap-on solid rocket boosters (SRBs) powered by polybutadiene. The SRB’s were jettisoned as planned about two minutes into the flight (see video).

Rendezvous at the ISS is scheduled to take place on Jan. 27.


After the HTV2 arrives in close proximity, astronauts on board will manually dock the cargo ship to the station. Using the stations Canadian built robotic arm, known as Canadarm2, the Expedition 26 crew of Cady Coleman and Scott Kelly from the US and Paolo Nespoli from Italy will grapple HTV2 and berth it to the Earth-facing port on the Harmony module.

KOUNOTORI 2 translates as ‘White Stork’ in Japanese.

HTV2 weighs 16,061 kilograms (35,408 pounds) and measures 10 meters long by 4 meters wide (33 feet by 13 feet). The vehicle can deliver both internal and external cargo to the station. In addition to Japanese equipment, the freighter is also loaded with over 2200 kg of experiments and supplies from NASA and Canada including both pressurized and unpressurized items.

This was the second launch of the HTV cargo carrier which was developed by the Japan Aerospace Exploration Agency (JAXA). The maiden launch occurred in September 2009 and was a test flight to demonstrate the autonomous and remotely-controlled rendezvous capabilities while also delivering cargo and supplies to the ISS.

Japan expects to construct and launch about one HTV per year with the capability to ramp up production to two vehicles per year if necessary and if the Japanese government approves funding.

JAXA is evaluating the possibility to convert the HTV into a vehicle capable of flying humans to space.

China, the other Asian superpower, has already established a human spaceflight program.

China has successfully launched three manned capsules to space and is vigorously moving forward with plans to orbit a manned space station.

After the forced retirement of the Space Shuttle later this year, NASA will be completely dependent on commercial companies and foreign governments to launch all of its future cargo requirements to the ISS.
