Greetings from Dr. Tamiya Nomura,
the first president

From the time of by-gone days when Icarus first flew the sky, the cosmos always has been the stage for the mankind to aspire after. Men always wished so much to fly in the sky with ever-growing curiosity to know the truth behind the twinkling stars in the night sky. Great progress achieved in the field of Astronomy has helped resolve one enigma after another of the cosmos.

There is, however, no end to the aspirations of the mankind. Wishing to fly further to the distance, the mankind finally stepped on the moon making the fullest use of the advanced technology of electronics and rocket propulsion. Today, quite a few number of surveyors are flying in the inter- planetary space and successfully achieving a most valuable observatory study of the origin and evolutionary enigmas of the eternal cosmos.

The task of protecting this Planet Earth from the present ecological crisis in terms of natural resources and environmental issues is unmistakably the most important job to be done by the mankind of the new century. And this task will never be achieved without gazing at the Planet Earth, our home planet, scientifically and objectively from the cosmic perspective. I believe that the population issue is the best example. The forecast of the world population's excess over 10 billion in the 21st century is most aptly suggestive that we can never survive only within this small framework of the Planet Earth.

Life was first born in the sea and evolved onto the land with the traces of mankind left everywhere on land of the Earth. The cosmos, therefore, is the greatest "New Frontier" which is left for the mankind.

In 1980 the late Dr. Carl Sagan, the noted space scientist and stronomer, Dr. Bruce Murray, then the director of NASA Jet Propulsion Laboratory and Dr. Louis Friedman, founded The Planetary Society (TPS) in Pasadena, California with the mission of supporting for and participating in the peaceful exploration program of the solar system from the standpoint of a non-governmental and non-profit organization. With 100,000 members in over 140 countries, the Society today is the largest space interest group in the world and has been very successfully active in cooperation with UN, NASA and each space agency of the countries and university laboratories throughout the world.

By keeping up with the most close working relationship with them, TPS thus has been active in exploration of planets, searching for extraterrestrial life in the universe and international cooperation on educational program of space science and contributing to the better understanding of the space by the people of the world.

Japan's first attempt was the launching of a pencil size rocket in 1955. Ever since then after a lot of hard works, "Ohsumi," the first satellite successfully launched in 1970, has become a stepping stone for Japan to join the world stage of space exploration. Japan now has entered into a new stage of Mars exploration program with "Nozomi" and other ambitious programs.

Taking the afore-mentioned circumstances into my serious consideration, we have come to decide to organize The Planetary Society of Japan (TPS/J), in close relationship with The Planetary Society (TPS) in Pasadena, California. Sharing the same ideals and philosophy with TPS, TPS/J is intended to organize a non-governmental and non-profit corporation. Our society is determined firmly to do our utmost efforts for inviting the society members to a far broader understanding and deeper charms of the space exploration.

Thank you all for your understanding and full cooperation to this new organization "The Planetary Society of Japan."
