Towards the H-3: Update

H-2A successor

Space News kindly published a version of my story on the H-3 last week. I’ve done the usual and pasted a version into this blog.

There is also a story by the ever excellent Warren Ferster on the Epsilon based on a JAXA presser. Please see this blog for more background on the Epsilon, or go to the new, vastly improved Space News website.

We can expect more light to be shone on this during June when the ONSP subcommittee makes its final recommendations. Meanwhile the Yomiuri and Asahi have some more information and perspective on the issue.

Our view in In Defense of Japan is that the H-series is a technology development program and while it may arouse screams of indignation and anger to say it, to put it bluntly, money will always be found to develop technologies that give Japan options. As, fundamentally, Saadia and I argue that Japan’s space program has always been basically, when you remove all the dressing, a dual-use strategic technology development program, then reasons to develop the H-3 will always be found.

As made plain by Dick Samuels and Mike Green, under nationalists such as Tomifumi Godai and in an era of rampant technonationalism and kokusanka, there were compelling reasons to develop the H-2. Japan wanted and needed to build a sophisticated, liquid fueled, highly efficient two-stage medium launch vehicle to cement its international reputation as part of the advanced spacefaring club. Remember, when the H-2 was envisaged over 20 years ago, few saw the impending “lost decade.”

Japan’s space program under NASDA was relatively awash with money, with investments made or planned  into all sorts of challenging dual-use precursor technologies including ETS-7 (on orbit ASAT demonstration) OICETS/ Kirari (laser communications), reconnaissance/ spy  satellites ICBM prototypes (M-V, J-1), reentry (OREX, USERS SEM) SIGINT (ETS-8), global strike (HYFLEX, HOPE) etc. Some highly ambitious programs that emerged last decade, have disappeared, for example HiMEOS and Smartsat-1.

On the other hand, ALSET looks as if it could make it.

Let’s not forget the H-2 very nearly made it to commercial viability but was fatally holed by the surging yen as well as dodgy turbopumps. So then money was found for the H-2A to solve the problem (half the costs, boost the payload) …but as we argue in In Defense of Japan, whether or not the H-2A really made it was not the issue. Could the program be justified in terms of a technology development program to the MoF. The peanuts in terms of cost involved in developing the H-2A compared to the cost of major launch vehicle systems by other advanced democracies (lets just name the Ariane 5) meant yes.

And now the cycle starts again. So how will the H-3 be sold to the MoF under the rubric of Japan’s latest stated space policy?

Sure, as something that will be commercially viable. Whether or not MHI and JAXA can actually achieve this is, we contend, strategically, a mute question. If and when the H-3 doesn’t make it commercially, MHI and Japan will have at least invested in developing a new level of excellent technologies that will secure Japan’s independent launch vehicle capabilities and provide jobs, technology and investment in its aerospace sector. Incidentally, the H-3 is now being sold by MHI as “catchup” again, as the slide above shows.

Sure, the same old cycle of vituperation and lashing will follow in the Japanese media if or when the H-3 fails to make the grade commercially, but the more strategic goals of “keeping/ catching up” will have been met.

Hayabusa-2 and Epsilon are Go

Technical Committee OKs Hayabusa-2 Development, Epsilon Launch in 2013
Very important strategic news for Japan’s space program as Japan’s Space Activities Commission (SAC) recommended the development of the Hayabusa-2 asteroid sample return mission after a key SAC evaluation committee approved of the technical development and mission goals of the project in a report published August 5.— The following is from something I filed at Space News a little while back. It’s highly significant because we are back where we started as SAC has returned as the de facto regulatory committee with the clout to justify MEXT’s spending programs.

In the 33-page report, the technical subcommittee, which has met three times since July 16, 2010, recommended that Hayabusa-2 be developed and launched before the end of March 2015 In outlining the mission’s goals, the draft report said Hayabusa-2 should visit, land on, deploy a miniature rover on and collect and return a sample of a C-class asteroid, which is considered to contain organic materials that can give clues to the formation of the solar system.

The report’s findings mean that SAC, which has oversight over the Japan Aerospace Exploration Agency (JAXA), will August 11 formally recommend development of the new probe as part of its review of JAXA’s space programs, according to Hiroko Takuma, deputy Director of the Space and Aeronautics Policy Division at the Ministry of Education, Culture, Sports, Science and Technology, in an August 5 interview.

Japan’s space budget request is submitted to the Finance Ministry at the end of each August and ratified by Japan’s Diet each following March in time for the fiscal year starting April 1. The budget for Hayabusa-2 is projected to be about 16.4 billion yen (US$190 million), excluding the launch cost of the H-2A, Takuma said.

Hayabusa-2 will be the follow-on mission for the Hayabusa (Falcon) mission, which was the fist space probe to successfully complete a round-trip to an asteroid when it to Earth in June 2010 following an 85-month journey in which it visited and collected dust particles from the near-Earth object 25143 Itokawa.

In a separate report, the same technical subcommittee also recommended development of the next-generation Epsilon solid-rocket that is the successor to the M-V. The 24 meter tall Epsilon, which is being designed by JAXA, is based on the SRB-A solid augment booster used by the H-2A, and will be capable of lifting 1,200 kg into low-Earth orbit at a target cost of 3.8 billion yen per launch, about half the cost of the M-V, according to the subcommittee report.

Following the draft report, SAC will also approve development of the Epsilon rocket on August 11, said Takuma.

– Initial Commentary:
Japan space watchers will already know how critical Epsilon is to not only Japan’s critical need of a small launcher following the GX debacle, but also to MEXT’s SOD initiative (Japan’s ORS) and the ASNARO/ Sasuke programs for Japan’s dual use military space infrastructure.

Epsilon is basically an updated version of the original  development program of the early 90s, using exactly the same solid booster technology supplemented by M-V know-how. The irony about this ORS/dual-use technology demonstrator program is that it actually goes some way to hitting the original objectives as laid out by the STA for this program back in 1997!!
