- SPACE, Page 58Japan Goes to the Moon
-
-
- A late space program takes off -- and bears watching
-
-
- The Japanese have a way of making big moves quietly. Only
- a handful of onlookers stood in the cold one evening last week
- to watch a slim red-and-silver rocket roar off the pad at the
- Kagoshima Space Center near Uchinoura, some 940 km (598 miles)
- southwest of Tokyo. But despite the minimal press coverage and
- lack of hoopla, the event was a major milestone for Japan's
- space program. The launch sent the unmanned Muses-A probe on
- its way to the moon, the first lunar mission since the Soviets'
- Luna 24 in 1976. Muses-A is expected to come within 16,000 km
- (10,000 miles) of the target in mid-March. It will then release
- a smaller probe, which will go into lunar orbit. If all goes as
- planned, Japan will become only the third country in history to
- reach earth's closest neighbor.
-
- That will be just one step in a sweeping initiative that
- could eventually make Japan one of the premier powers in space.
- Muses-A is a prelude to future unmanned missions that may land
- on the moon and explore the atmosphere of Venus. At the same
- time, Japan is building a new booster rocket that could make
- the country a strong competitor in the burgeoning business of
- launching commercial satellites into earth orbit. The Japanese
- have announced no plans for manned space flights, but they are
- considering the possibility. Already their companies have begun
- developing construction techniques for use in building bases
- on the moon and even Mars.
-
- In short, the Japanese are pursuing their space ventures
- with all the thoroughness and enthusiasm that made them world
- leaders in electronics and autos. Says Ray Williamson, a senior
- analyst for the U.S. Congressional Office of Technology
- Assessment: "The U.S. ought to keep a clear eye on their
- developing capabilities. Progress is steady, and the Japanese
- are serious about space."
-
- Japan's progress is all the more impressive considering the
- obstacles its program has faced over the years. The U.S. and
- the Soviet Union originally used military-rocket technology to
- get a head start on scientific launches. But Japan's
- constitutional curbs on military activity forced its rocket
- scientists to start from scratch, and tight government budgets
- have not helped. In the current fiscal year, for example, Japan
- has allocated some $1.07 billion for space, about 10% of the
- U.S. figure. And launches are limited to only 90 days a year,
- half in winter and half in summer, because tuna fishermen near
- the space center claim that rockets are dangerous and scare
- away fish.
-
- Another problem has been the more than two decades of
- bureaucratic rivalry between two Japanese space groups, the
- National Space Development Agency and the Institute of Space
- and Astronautical Science. ISAS focuses on academic scientific
- research, like the Muses-A mission, while NASDA's main business
- is to launch satellites for more practical uses, such as
- weather observation and communications. Combining these
- agencies and eliminating overlapping functions would make for
- a more efficient program.
-
- For all those reasons, Japan was a late bloomer in space.
- It did not put its first satellite into earth orbit until 1970,
- six months after the U.S. landed men on the moon. But Japan has
- come on fast by stressing efficiency and borrowing rocket
- technology from other nations. For example, the country's
- workhorse launcher, the H-1, is a modified version of the
- 30-year-old U.S. Delta rocket. Most striking is Japan's record
- of consistency: ISAS has had only two failures in 19 launches,
- both in the 1970s.
-
- The country is now trying to free itself from dependence on
- foreign know-how by developing its own booster. The H-2,
- scheduled for its first test launch in 1993, will be able to
- put a two-ton spacecraft into high earth orbit. That is
- competitive with Europe's Ariane 4, the U.S. Titan and the
- Soviets' Proton booster, all of which are being marketed as
- commercial launchers.
-
- While the Japanese are becoming more independent, they are
- also starting cooperative ventures in areas where their
- experience and resources are insufficient to go it alone. They
- will help design the U.S.-Japanese Geotail satellite, which
- will explore the earth's magnetic field in 1992. They have
- agreed to build part of the proposed U.S. space station. And
- ISAS may contribute equipment to an unmanned Soviet Mars probe
- in 1994.
-
- Some Japanese companies, meanwhile, are trying to get the
- inside track on international missions that have not even been
- scheduled yet. Shimizu, a construction firm, has opened a
- space-projects section to develop ideas for a moon base, either
- Japanese or American. The company has already begun work on how
- concrete made from lunar soil could be used to form large
- structures. Ohbayashi, also in the construction business, will
- join American companies in building a $100 million facility for
- lunar-base research in Florida.
-
- U.S. scientists and officials do not feel much threatened
- by Japan's space ambitions. Its participation will help hold
- down the costs of future U.S. missions, and scientific data
- from exclusively Japanese probes will be available to all.
- Despite its many achievements, Japan remains significantly
- behind both the U.S. and the Soviet Union in space technology.
- Still, given the country's record in other areas, it may be a
- Japanese crew that first sets foot on Mars early in the coming
- century.
