Politica fundamental de las actividades espaciales de la NASDA.
Revisado por la Comision de Actividades Espaciales el 24 de Enero de 1996.
Life on Earth started in the sea, then moved to land and then to the sky. Mankind, now in the forefront of evolution is using science and technology to move into space.
Mankind has been long seeking answers to basic questions: Why does space and the solar system exist? How was life created on the Earth? Scientific research into those question conducted in space will become increasingly important in the 2lst century. Knowledge obtained by space activities is likely to make us all think differently about the universe, the Earth, and life itself, contributing to the creation of a new philosophy and culture, and to the establishment of an intellectual, mature society.
As we have already seen, satellite services have become an essential part of our daily lives. These services include satellite communication and broadcasting, navigation by the global positioning system (GPS) for ships and cars, and weather forecasts by meteorological satellites. These satellite services will become more sophisticated , an indispensable part of an advanced information society, and contribute to improved life styles. In addition, unique characteristics of space such as the microgravity environment is expected to yield new materials and medicines.
Satellites can also detect and observe accurately changes in the weather, oceans , and land surfaces, as well as global warming, deforestation, increase in desertification, the state of ozone layer, and disasters. Activities in space, then, have considerable potential for contributing to science, and for preserving the environment.
Furthermore, space technology must be high reliable and operate in a severe environment. As such, it is a highly sophisticated generic technology which integrates various fields of science and technology. Efforts to develop and advance space technology could yield new industrial technologies in fields such as materials, computer, robotics, electronics, communications, and information processing. It is expected to create a new industrial sector using these technologies.
Finally, space can be one of the most challenging fields for young people to pursue. It is, therefore, very important to make young people dream of space, and give them an enterprising spirit. This will contribute to development, not only in science and technology, but also in other fields, as well as maintain the vitality of our economy and society.
With the importance of developing space in mind, Japan has made incessant efforts in this field, beginning with the development of small rockets at Tokyo University's Institute of Industrial Science. Since then, Japan has become highly regarded by the international community in various fields of space science. In space development and application fields , such as communications, broadcasting, and meteorological satellites, Japan has developed its own technology. Through successful launches of the H-II, and the development of various satellites, Japan has achieved world class standards in some space technologies.
The US and Russia are now shifting
the emphasis of their space programs from military projects and
matters of national prestige, to cost/benefit contexts and high
technology development for use in commercial applications.
In addition, Europe is actively promoting commercial launch
services, and China is participating in commercial activities
with its own technology. There is thus a growing emphasis among
those major countries on the civilian use of space.
Another new development in space is Russia's participation in the
International Space Station Project, a collaborative project
between the US, Europe, Japan, and Canada. That international
cooperation is likely to become common, especially in the field
of large space development projects like the space station.
Two factors can thus be identified as important themes for
worldwide space development in the 2lst century : civilian use
and international cooperation.
As a result of the above- mentioned changes at home and abroad, Japan should now take a new approach to its space activities in the 2lst century. We should recognize the significance of space development and the world wide trend towards both civilian use and international cooperation in space activities. We have to play an active role in international space projects by improving our level of our space technology, and by pursuing the use of space from a global standpoint.
The Basic Law on Science and Technology enacted in November 1995 proclaims the promotion of science and technology as one of the most important national themes, and requires that science and technology be promoted in a well- balanced, well-organized manner. We consider it extremely important not only to encourage space science and earth science, but also to stimulate R & D in advanced space technologies in order to create new technology or new industries . To promote science and technology in accordance with the afore mentioned Basic Law, we must pursue more robust and qualified space development.
The Space Activities Commission
formulated the Fundamental Policy for Japan's Space Activities, a
long-term basic guideline for Japan's space activities, in March
1978. Since then the Commission has revised the policy twice, in
February 1984 and June 1989, to accommodate changes in the
domestic and world situations.
The Space Activities Commission has now revised the policy again,
based upon the above-mentioned notions and upon the report called
" Toward the Creation of a Space Age in the New Century
" produced by the Special Committee on Long- Term Vision,
one of the Committees under the Commission. The revised version
should shape the future direction and framework of Japan's space
activities for the next ten years.
To ensure the appropriateness of Japan's space development policy, the revised version will be reviewed regularly in light of progress in science and technology, or on domestic and foreign events.
Japan promotes the development of space in the context of the domestic and international situation, and for peaceful purposes, based on the following basic policies.
In addition to these endeavors, we will try to establish a global Earth observation system through the coordination of observing satellites from various countries.
(1)
Series of Earth Observation Satellites
A series of Earth observation satellites will be
developed and operated in a way to efficiently meet
users' needs at home and abroad, and to maintain harmony
with other countries' observation and research projects.
This will be done through a collaboration by the National
Space Development Agency of Japan (NASDA, a development
and implementing agency), as well as universities,
national research institutes, the private sector, and
government agencies. The Earth observation satellite
series consists of two categories: atmospheric and
oceanic observation satellites and land observation
satellites.
The development/implementing agency and user organizations, will co-operate to improve sensor precision and resolution, and to develop a new sensors. Aircraft, the JEM, and satellites will be used, if necessary, to ensure effective implementation of new sensor developments.
Meteorological satellites will be launched and operated continuously to provide regular observation data.
(2) Use of Observation
Data
To improve the use of observational data from Japanese
and foreign earth observation satellites, work to verify
data validity, standardize data quality and format, and
create data processing and analytical software, will be
pursued. At the same time, ground stations and an
information network for users will be established.
The development and implementing agency and the user organizations will make joint efforts to reinforce the institutional framework for data use, by using the existing systems for cooperative research and for inviting researchers.
(3) Global Earth
Observation System
Japan will try to play a proper role in establishing a
global earth observation system, in harmony with the
earth observing satellites of other countries and through
positive international consultation and coordination.
(1) Series of Medium- Size
Science Satellites and Space Probes
The medium- size science satellites and space probes will
be developed and launched by the M- V rocket about once a
year. By using these satellites, science exploration of
the near earth space, the moon and asteroids and of the
solar system will be conducted together with astronomical
observation on wider wavelengths, in conjuction with
observation from the Earth.
(2) Large Science
Satellites and Space Probes
Scientific research and astronomical observation of the
sun and planets will be conducted using a large satellite
and a space probe, launched either by the H-II launch
vehicle or through international collaboration.
(1) Unmanned Exploration
NASDA and the Institute of Space and Astronautical
Science (ISAS), in cooperation with other agencies , will
conduct an unmanned lunar exploration project including
the development of a lunar orbiting satellite and a lunar
landing vehicle. Project planning will take into account
and international aspects of the venture as well as
progress in technology.
(2) Scientific
Observation and Exploration from the Moon
Keeping other countries' Lunar programs in mind, the
National Astronomical Observatory, ISAS, and NASDA will
jointly promote research and development of observation
technology and lunar infrastructure technology. This will
be done for future moon projects such as international
lunar observatory and a long-term lunar mission.
(1) Communication
Development of personal satellite-based mobile
communications will be promoted to help strengthen our
communication infrastructure. Advanced satellite
communication technology, such as gigabit-class, ultra
high-speed satellite communication technology,
millimeter-wave or laser satellite communication
technology, will be developed with the aim of
establishing an international high-speed satellite
communication network.
(2) Broadcasting
Digital and high precision broadcasting, satellite
broadcasting technology related to mobile digital
multimedia broadcasting and new broad-bandwidth satellite
broadcasting will be developed.
(3) Navigation
The GPS navigation satellites launched by the U.S. is
used by ships and cars, and as a research tool for
determining causes of earthquakes and volcanic activity
as well as for measurement required for public use. In
order to cope with the growing sophistication and
diversification of needs in our country, we will develop
elementary technology for navigation systems, to improve
precision. We will also develop new navigation
technologies associated with communications.
(4) The Aviation
A satellite will be launched and operated to ensure
safety and efficiency of air traffic control.
In addition, we should pursue research on uses of space in various ways including international cooperation, orbital experiments, and joint research projects on the ground among NASDA, universities, and national research laboratories.
(1) Space Experiments
In addition to promoting JEM's development and operation,
we will perform space experiments using drop towers,
aircraft, small rockets, recoverable capsules, and the US
Space Shuttle, choosing the facility according to the
experiment's characteristics . We will also develop
experimental equipment and technology, such as unmanned
space experiment systems, to meet various demands for
space utilization.
(2) Research System
With a view to ensuring wide use of results from future
space projects, it is important that we enhance the
research system so that researchers from universities,
national research institutes, and the private sector can
participate.
In this sense, NASDA, universities, the national research laboratories, and the private sector will promote joint research projects. NASDA will make use of the personnel exchange program to play a leading role in this field.
NASDA will also promote effective and wide use of the research system by strengthening the existing support system. At the same time, we will work to ensure safety of on-board equipment, construction of a database for research results, and establishment of an information network for research.
(1) Manned Space Technology
Experience and expertise in crew selection, training, and
healthcare will be accumulated through JEM's development
and operation, as well as the use of US Space Shuttle.
The Technology for intravehicular activity,
extravehicular activity, and manned space systems,
including safety and reliability, will also be acquired.
(2) Space Medical
Science
Research on the calcium depletion of human bone, and on
the radiation effects of stays in space will be expanded.
Moreover we will endeavor to study the closed ecosystem necessary for man to live in space, to acquire basic technology related to manned space activities, and to train personnel for the job.
(1) Mission Demonstration Satellites
Series
It is necessary to develop mission equipment, including
earth observation sensors, with a view to familiarizing
the public with the use of space. For the development of
communications , broadcasting, and navigation, we must
reduce technological risks by using operational
satellites to verify technology.
As a matter of fact, some mission equipment and space missions have been verified using the Engineering Test Satellites (ETS)series. This verification work will now involve developing a new series of the mission demonstration satellites. Implementing the new series will require cooperation between NASDA, the government agencies, universities, national research laboratories, and the private sector, including making satellite development cheaper and easier by adopting a common satellite bus . We are now also discussing the introduction of announcement of opportunities (AOs).
(2) Engineering Test
Satellites (ETS) Series
We will emphasize further development and efficiently
responce to more sophisticated and diversified needs in
future satellites. With this in mind, we will use the ETS
series to develop generic technologies, such as platform
satellite technology and rendezvous-docking technology.
By developing the ETS series, we will acquire basic satellite technologies such as on-board equipment miniaturization, Iight-weight materials, and power reduction and conservation. In addition, we will be able to improve the reliability of electronic and mechanical devices, as well as the performance of on-board software.
(3) Satellite Bus
Technology
We have several different kinds of satellite bus in
Japan. We will now reduce development risks and cost of
the mission demonstration satellites and the earth
observing satellites by adopting a common satellite bus .
Furthermore, element devices for satellite buses will be
standardized and designed for easy conversion into
general use.
(1)
Transportation System
(i) M
launch vehicle
To advance our space science, which has been
highly praised by other countries, we will
develop and upgrade the M-V launch vehicle. We
intend to use this vehicle to launch medium-size
science satellites and space probe projects.
(ii) H-II
launch vehicle
The H-II launch vehicle will be able to adapt to
launch demands, through continuous efforts to
upgrade and improve its reliability. Such efforts
will allow an advanced H-II launch vehicle (H-II
A) to launch a 20-ton payload into low Earth
orbit (or a 4-ton payload into geostationary
orbit) with a potentially major cost reductions.
This vehicle will be developed to meet various
needs in the 2lst century, including access to
the space station.
(iii) Small
payload launch vehicle
Small launch vehicles including the J-I launch
vehicle , will be developed to launch small
satellites.
(iv) HOPE-X
HOPE-X will be developed to perform flight
experiments as a part of reusable transportation
system, which should drastically reduce
transportation costs. HOPE-X will establish major
technologies for an unmanned, winged space plane
and enable us to accumulate technology for a
future study of reusable transportation systems .
(v) H-II
Transfer Vehicle (HTV)
We will develop and operate the HTV with
rendezvous and docking functions to prepare for
the task of supplying logistics to the space
station.
(vi) Future
Transportation System
In order to meet future transportation demands we
will require, a reusable transportation system
with an innovative design. The system will also
be necessary to drastically reduce transportation
costs and protect the space environment . Based
upon the results of H-II A and HOPE-X development
projects, we will initiate a study for a reusable
transportation vehicle including an unmanned
winged space plane. We will also start, if
necessary, its development, taking into
consideration both international and demand
trends. Later we will also start research into a
fully reusable aerospace plane (space plane) with
the capacity of horizontal take-off and landing,
in cooperation with the related research
institutes.
A study for a manned space plane will also be started as part of the preparation for manned space activities. Another study for an orbit transfer vehicle, capable of moving from one orbit to another, will be initiated to prepare for moon exploration.
(2) On-Orbit
System
(i)
Unmanned System
To help implement space experiments, we will
develop a platform type satellite in
low-and-medium altitude Earth orbits. In
implementating this project, the possibility of
international cooperation should be considered.
After the platform type satellite is developed
and operated, an orbital service vehicle will be
required. So, proper coordination for these two
projects is important.
(ii) Manned
System
Based upon the experience and know-how obtained
from the development and operation of the JEM,
research work will begin on improved and more
economical manned systems.
(3) Support
System
(i)
Modification of Launch Site and Landing Field
Due to the complexity and expansion of space
activities, the launch site for the H-II A will
be modified, and a new landing field for HOPE-X
will be prepared. It may be necessary to
formulate a new policy for managing and operating
the launch pads, since expanded demand for
satellite launches has been forecast for the 2lst
century, together with considerable space
development. Necessary measures will be
discussed, taking into account the issues of
safety and organizing international cooperation.
(ii) Data Relay
and Tracking Satellite System
The Data Relay and Test Satellite System (DRTS)
will be developed to transmit a large amount of
observational data and experimental data from
satellites in low and medium Earth orbit to
ground stations, and to provide regular tracking
and control services for those satellites. The
technology for intersatellite laser
communications technology, which is regarded a
component of future tracking and control systems,
will be investigated in orbit. Automation and
autonomy will be developed to further improve
tracking and control system.
(iii)
Monitoring Space Debris
In order to support manned space activities, as
well as expanded and more sophisticated unmanned
space activities, we will conduct research on
space debris monitoring systems , and space
weather forecasting systems in order to predict
space radiation. In addition, large volume data
transmission systems will be studied in order to
strengthen the space information and
communication infrastructure.
It is important to co-ordinate Japan's space development and utilization activities with one body, and increasing their efficiency by devising a definite plan. In this context, NASDA and ISAS, Japan's space development and implementing agencies, will be consolidated. This move will enhance their technological ability, and their cooperative relations with other organizations, and improve the efficient development of space.
There is also a growing need to improve cooperation between space science and practical space application. Closer and more efficient relations between NASDA and ISAS, which play leading roles in their own fields, will be ensured in the fields of moon exploration, space environment utilization, and others.
In space development we will be expected:
When we engage in such cooperation, we must ensure mutual benefits and reciprocity by taking full account of our national condition as well as that of cooperating partners . It is also essential to clearly define the purposes and objectives of the cooperation, and to conduct it in a well-organized manner. To those ends , we will implement the following measures:
To familiarize the public with space activities and integrate them into daily life, the private sector must conduct more vigorous activities. In addition, to help implement the national space projects, the space manufacturing industry must consolidate.
Our space industry will be expected to improve its technology and expand its business activities. To improve the private sector's space activities, the Japanese government will take the following measures:
The private sector's use of space will expand as social and public needs increase, due to reduced costs and increased reliability of space. The expansion in use will also contribute both to creating new industries, and expanding the space manufacturing industry through increased demand for space equipment.
For the purpose of encouraging the use of space in the private sector, the following measures will be taken to:
(1) Introduction of proper monetary and tax measures.
(2) By paying attention to our participation in the use of space at reasonable cost.
It is the responsibility of those
who take charge of space development to gain public understanding
and support for space activities. In that context, public
relations activities informing persons in every walk of life,
particularly young people, about the significance of space
development and its expected results are indispensable. Those
activities will also provide people with an opportunity to see
the development of space through various media, exhibitions, and
meetings.
It is, therefore, important to reinforce our public relations
activities by taking the following measures:
Future space development will require more and better trained pesonnel in the space field. For this reason, special measures will be introduced to find and train the researchers and engineers who will be the main promoters of space development, and young people who will be responsible for this field in the future. These include:
Since space activities are connected with a number of scientific and technological disciplines and are subject to a rapid change, it is important to ensure the efficient use of research results, technical information, and observational data. To achieve that aim, an effort will be made to restructure the information flow system, such as relevant data bases and information networks . Moreover, we will also encourage the connection of our networks with foreign information networks, to provide domestic and foreign data on Earth observation and on space environment utilization to users. We will also ensure more effective distribution of development results over those networks.
In order to implement the items proposed in the Fundamental Policy of Japan's Space Activities, we will try to share the financial burden with the private sector. Specifically, we will try to secure a steady increase in the national budget, and make use of other resources, including private ones.
