Japanese Space Program Braces For Cuts

Here is a shorter version of the longer article that was published in Aviation Week last month. It was great to have the chance to write a little bit about what is going on in Japan. I’m posting this now, since Japan is nearing a decision on exactly what sort of H-3 launch vehicle it wants, for example, here, here, here and here, just to name a few. I’ll just post the longer form article and then my take on the H-3.

TOKYO — As Japan’s space policy plans shift away from research and development, the Japan Aerospace Exploration Agency (JAXA) is finding its flagship science, technology and manned spaceflight programs in line for cuts and cancellations.

Some or all of Japan’s satellites planned for the Global Earth Observation System of Systems (GEOSS), the HTV-R pressurized sample-and-crew-return mini-shuttle, and the H-X/H-3 launcher programs could face cancellation, says JAXA’s Hiroshi Sasaki, senior advisor for the strategic planning and management department.

Epsilon rocketNew laws have placed control of the Japanese space agency in the hands of the Office of National Space Policy. And ONSP director Hirotoshi Kunitomo seeks to reorient Japan’s space efforts from idealism to realism.

ONSP will continue to support frontier science as a lower priority, providing it is based on the sort of low-cost, high-impact space science designed by JAXA’s Institute of Space and Astronautical Science (ISAS), embodied by the Hayabusa asteroid sample return mission. But former high-priority goals to promote environmental monitoring, human space activities and putting robots on the Moon are now much lower priorities and will have to fight for funding, Kunitomo says.

Instead, ONSP is focusing on three core programs, and only one of them, Japan’s launch vehicles, is a JAXA program.

The highest priority effort, run by the ONSP, is to build out the Quasi-Zenith Satellite System (QZSS), Japan’s regional GPS overlay, with a budget approved for maintaining a constellation of four QZSS satellites by around 2018. A post-2020 build out to a seven-satellite constellation will then give Japan its own independent regional positioning, navigation and timing capability.

The second is the Association of Southeast Asian Nation’s (ASEAN) newly sanctioned Disaster Management Network run by the Ministry of Economy Trade and Industry (METI). This requires a constellation of Earth-observing optical, X- and L-band radar and hyperspectral sensor-equipped satellites monitoring Southeast Asia. Japan will provide at least the first three satellites, with more funding through foreign aid packages. Vietnam has already signed up for two X-band satellites. Stated policy requires a once-daily revisit over any part of the Earth, requiring a minimum constellation of four satellites that will need to be regularly replenished every five years or so.

The third priority focuses is on improving the current H-2A, which JAXA is working on with Mitsubishi Heavy Industries (MHI). It is also continuing improvement of JAXA’s new low-cost, launch-on-demand Epsilon solid launch rocket for smaller payloads. A variant will be uprated from 1,200 kg (2,650 lb.) to around 1,800 kg to low Earth orbit, matching that of its predecessor M-V launch vehicle.

JAXA projects that fall short of the Basic Plan’s goals but are already funded for development will continue if it is counterproductive to stop them, Kunitomo says. These include launching the upcoming ALOS-2 land-observing system and the Global Precipitation Measurement/Dual-frequency Precipitation Radar satellites. The greenhouse-gases-focused Observing Satellite-2 (GOSAT-2) is also safe, as it is funded by the Environment Ministry, not JAXA.

But under a Feb. 25 budget plan drawn up by Kunitomo, several programs face harsh scrutiny, including the HTV-R sample return mission, any future launches of the HTV-R transfer vehicle beyond the current seven planned through 2016, the H-3, Moon exploration and all of JAXA’s follow-on environmental missions.

Harsh logic

The ONSP’s logic for re-auditing the HTV-R is harsh. As it is too expensive to commercialize, the H-2B will be ditched as dead once its HTV duties are finished. As the HTV’s only purpose is to service the International Space Station, andImage Japan must minimize its costs, then logically the HTV, HTV-R and H-2B have no future beyond 2016 and the HTV’s seventh flight. Indeed, one industry source tells Aviation Week that Japan may launch perhaps two, at most, post-2016 missions.

For JAXA, things get tougher. ONSP plans mandate that the agency’s now-low priority environmental monitoring programs undergo a “focus and re-selection process.” This means the proposed GCOM-C, EarthCARE cloud radar mission and ALOS-3 electro-optical missions — the second main plank of Japan’s flagship international cooperation programs with NASA and the European Space Agency — will fight for funding, and not all will make it, Kunitomo says. But he concedes a reconfigured ALOS-3 that can adapt to the Disaster Management Network at a fraction of its projected price tag would become more acceptable.

Japan Tests REBR

2011年4月3日

With the Epsilon confirmed for development, Japan’s latest reentry technology experiment appears to have been conducted successfully with the test of  the U.S. Department of Defense’s Re-entry Breakup Recorder (REBR) on Kounotori 2 on March 31.

REBR recorded temperature, acceleration, rotational rate and other data during the  controlled reentry and successfully phoned home that data prior to final impact and was still  transmitting while floating in the ocean. REBR was made possible by using miniature sensors and cell phone technology, built as basically a satellite phone with a heat shield.

REBR’s stated purpose is to collect data during atmospheric reentries of space hardware in order to help understand breakup and increase the safety of such reentries. Of course this data is valuable for a number of dual-use reasons. Let’s not talking about improving the accuracy of warheads for now, however.

The robotic HTV-2 (Kountori-2) is a highly-advanced automatic cargo carrier for the ISS

The REBR project is supported by the U.S. Air Force, NASA, and the Boeing Company. The first flight test of the small, autonomous device was coordinated by the Department of Defense’s Space Test Program which includes the Orbital Express program which is dual-use ASAT technology demonstrator, on top of a variety of military microsatellites tested and under development by the STP.

In Japan’s case, REBR  began collecting data,  ultimately detaching from the disintegrating spacecraft and continuing in freefall from approximately 60,000 feet from the ocean. REBR effectively made a “phone call” over about five minutes before landing in the Pacific Ocean.

A second test will be REBR’s reentry aboard the European Autonomous Transfer Vehicle 2, called Johannes Kepler, in early June.

As we pointed out in In Defense of Japan, Japan has made sure to accumulate reentry targeting technology through Hyflex, Express, USERS, and so on as part of its securing the technology option to develop a counterforce strategy based on Epsilon and the ability to develop highly compact, boosted fission warheads based on the country’s supply of supergrade.

Now the gloves appear to be off with JAXA working directly with the DOD.

Japan Maps Pathway to H-X

….First steps halted by lack of budget…

I get sort of incredulous when folks talk about the various failures of Japan’s space development programs to do this and that. The only things Japan’s space development program is guilty of is being inexpensive and successful.  How much did Kounotori cost to develop then, and the H-2B?

Following the Asahi’s punt at describing JAXA’s H-3 rocket earlier this year, I decided to take look at Japan’s steps toward human spaceflight via upgrading the H-2 family. After talking to MHI back in 2005, I didn’t expect too many changes, with the primary new technology driver for the H-3 being the LE-X engine.

Five years later, and things seem to be on the same course, although JAXA is now openly offering its development schedules and plans to those interested and it makes for a great look into the future.

First of all, the fact that JAXA will be embarking on a “Phase I” upgrade this April spurred me to file an article for Space News, which is now below. Initially I’d like to make comments on the missing elements of this story and background that can’t be crammed in a 550-750 word article, and then I’ll move on to future plans in more detail in Part II, which will also show just how advanced thinking is on polishing the space silverware in Japan.

First of all, here is the story, then some follow-up below:

Comments:
Ever since I first started writing on the H-II, with a story on Nissan importing CFRP technology for the  H-2A’s initial SRB-As, what, back in 1997 as I remember, we have been “waiting” for the H-IIA  to fulfill its stated public goal of being “commercially” successful.

In many ways, one of the key points about In Defense of Japan is that it doesn’t really, really matter if the H-2A is commercially successful or not, because the money will always be found to keep on developing Japan’s liquid  and solid) propulsion and system integration technology, whether the rocket makes a profit in the commercial marketplace or not.

There are several parts to this argument: but my point is that that fundamentally, money will always be found because that’s been essential part of Japan’s technonationalist industrial policy since the Meij Ishin period (see Rich Nation, Strong Army, which forms an essential plank for the arguments in In Defense of Japan).

Beyond the spin-on, spin-off paradigm, and MHI’s long-standing interest in microsatellites, MHI is very keen to get the story about about these upgrades because they show the strong commitment to improving this wonderful system, showcase MHI’s and Japan’s technologies, and well, if the yen were even 120 to the dollar, how cheap would the H-2A be compared to the Atlas anyway?

That’s wishful thinking, but it is a fact that Tanegashima’s issues don’t begin and end with ralicraltant fishing unions who need regular dollops of fiscal and pools of alcoholic lubrication to open up the launch windows.

However the physics of getting a payload into orbit from Southern Japan don’t change no matter how much awamori is consumed. Firstly, the rocket has to take a bit of a long and winding ascent to avoid you name it South East Asian nations who don’t appreciate tons of flaming toxic space debris landing on them should the worst happen. Then, and here’s the spin, Tanegashima is quite a way off the equator meaning the H-2A is loosing out on arrival as well. So the top line is the bottom line and MHI are very keen to point out that the long-cruise capability saves (potential) customers money.

The second point I would like to make is that the upgrade I wrote about is actually a stripped down version. The Epsilon has also been hit. Despite both LVs being high priority, penny pinching means that the improvements to the H-2A and the Epsilon are actually strung out to a different timetable and diluted implementation compared to what even was the consensus for the development pathways as late as last September.
