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 Sets Next H-2A and Kounotori-3 Launches

Jaxa and MHI have just announced that they have set the launch dates for the next H-2A and Kounotori-3 (HTV-3).

H-2A flight 21 is scheduled to launch JAXA’s Global Changing Observation Mission 1st – Water  “SHIZUKU” (GCOM-W1) and the KOMPSAT-3 (Korean Multi-purpose Satellite 1)  of the Korea Aerospace Research Institute (KARI) May 18 (Friday), 2012 (Japan Standard Time) at  1:39 a.m. thru 1:42 a.m. (Japan Standard Time).

To capitalize on the excess launch capability of the H-IIA F21, Japan is also provide launch and orbit injection opportunities for two small secondary  payloads.

Also H-II Transfer Vehicle Kounotori-3 (HTV-3)  aboard the H-2B Launch Vehicle No. 3 is scheduled for launch on  July 21 (Saturday), 2012 (Japan Standard Time, JST) around 11:18 a.m. (JST). The launch window will run July 22 (Sunday) through August 31 (Friday), 2012 (JST) at the Yoshinobu Launch Complex at the Tanegashima Space Center.

It’s going to be a busy time for JAXA and MHI and a lot is riding on both missions.

First of all with the STS now retired, Japan is taking a vital role in resupplying ISS and both the HTV and the H-2B relatively new.

MHI and JAXA have been on a 12-year campaign to fully master the H-2 A/B technologies but the H-2B and HTV, a highly advanced automatic tug and the subject of more than 20 years of research by JAXA, are  still very early into their launch careers. Experienced space watchers know that new technologies are still on probation until their launch rates reach double figures. Of course, failure of the mission to the ISS would not only be an international disaster for Japan, but cause the ISS program many issues.

There is also a lot riding on the KOMPSAT launch, as the H-2A is carrying a major Korean research satellite. While the ROK has found out that launch systems are extremely difficult to develop, having seen its first two efforts end unhappily, a failure of a launch of a prize Korean satellite aboard a Japanese rocket could deeply impact fractious Japan-ROK relations unless handled well by both sides. No doubt vituperation (from the ROK side) and conspiracy theories will abound.

The Kunotori mission is carrying several intriguing payloads, including two reentry accuracy and measurement experiments; the REBR (Reentry Breakup Recorder) manufactured by  Aerospace Corporation, which will record data regarding the thermal, acceleration, rotational and other stresses that Kounotori will go through as it breaks up on reentry,  and the much larger (22kg) i-Ball by IHI Aerospace which will do a similar job, but also has a camera.

JAXA is planning to release Cubesats from the International Space Station using the JEM’s  robot hand, from Japan these will be  RAIKO (Wakayama University) FITSAT-1 (Fukuoka Institute of Technology) and the WE WISH radio ham cubesats and TechEdSat built by San Jose State University and the F-1 cubesat by FPT University.

Good luck, chaps.

Path to the H-X Part II

2011年5月9日

Earlier we took a look at the development of the improved H-2A/B rocket that is going to “lower costs” for commercial satellites to help the H-2A compete in the global market.

Well that may be true, but the key point about the improvements is that they follow Japan’s traditional approach to technology investment- kaizen. By continually learning and improving, the spin-on for Japan’s ability to put be able to put all sorts of payloads in all sorts of places is the necessary deeper function of the dual-use technonationalist development paradigm.

This article looks at the deeper story behind the improved H-2A. Like the Epsilon, development has been pushed out. Unlike the Epsilon, the future potential evolution of the H-series to human rating is quite clear.

The first thing to point out is that the upgrades I wrote about in Space News are a deal less ambitious than those originally planned last September. I the original plans for these through the spring, but they were embargoed. Now they’re to have as a reference.

LE-X and H-X

Anyway, lets step back and take a look at how Japan’s rocket program rose and fell and rose again, the inflection points being the February 21, 1998 (crack in LE-5A cooling chamber, dodgy brazing,) and November 15, 1999 (fatigue failure LE-7A inducer) back-to-back failures of the H-2 and then the November 29, 2003 failure (nozzle erosion, SRB-A) of the H-2A carrying two IGS spy satellites.

It was the failure of the H-2A’s Nissan/Thiokol technology SRB-A that particularly incensed then-SAC Commissioner Iguchi, who slammed his desk in frustration: “We forgot to check the SRB-A!” he exclaimed, and rankled Takeo Kawamura (then MEXT-minister and in-name-only responsible for the cursed booster’s non-separation from the core stage) enough to begin the process of reforming Japan’s space governance- reforms that are just now being resolved by Yamakawa sensei.

We shall overcome indeed.

But since then the H-2A/B have flown with a perfect record, with the H-2B representing a literally huge boost to Japan’s LV integration skills as well as its launch capacity all for a couple of hundred million bucks. Yes, THAT GOOD!

Apart from improvements in nozzles, cavitation, valves and vibration, JAXA and MHI’s continuous kaizen have led to a number of other improvements of other weaknesses, including separating redundancy lines to make them even more robust, and protecting the wire harness, lets never remember that these rockets work as designed and developed at a cost one order lower than their U.S. rivals.

Another one of those failures by Japan’s doomed and disaster-prone space program, right?

Now lets go to the H-X, which is scheduled for development in 2020; the key weapon for this is the LE-X engine, which will use a high-thrust expander bleed cycle engine, making it inherently more safe and robust.

Thrust will be 1450kN, Specific Impulse (vacuum)  432 seconds and the rotational speeds of the FTP and OTP will be 40,800 rpm and 16,100 rpm respectively.  The engine will feature a simplified manifold for the injector, a single-sage open impeller with a two-stage inducer for the fuel turbo pump, a spin-form single sheet metallic nozzle and the oxygen turbo pump will feature a single-stage impeller and a two-stage turbine. Component testing is due to start next year with prototype engine test firing in 2015 and qualification tests beginning in 2017. If everything goes according to plan -a big if of course- then a test flight might be feasible as early as 2018, according to internal JAXA documents.

Will Japan pull it off and be launching a manned H-X in 2020. I don’t think so- there isn’t the will nor the money. Can Japan do it?

You bet!

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.
