Preface
The international workshop ``Mid- and Far-Infrared Astronomy
and Future Space Missions'' was held on April 17 and 18, 2000
at ISAS. The purpose of this workshop was to investigate the
scientific significance and technical feasibility of
large-aperture cooled space infrared telescopes.
About 120 astronomers and engineers from all over the world
participated and the workshop was very successful. In particular,
the recent results of ISO, status of the development of
ASTRO-F and
future big missions such as NGST and FIRST, and related scientific
discussions were very exciting and fruitful.
The last part of the workshop was dedicated
for the discussions on future possibilities.
The importance and necessity of a
large-aperture cooled telescope in space, as being
complementary to missions such as NGST and FIRST, was acknowledged by all the
participants.
The HII/L2 mission
now under study in Japan,
was regarded as promising for this purpose.
Moreover, the importance of international collaboration to consider the
possibility of larger-aperture telescopes was
emphasized. It was also recommended
to organize this kind workshops on a continuing basis.
We would like to thank the Science Organizing Committee,
the chair persons of sessions, and the Local Organizing Committee for
their efforts in making this workshop very successful. We are also
thankful to Ms. H. Kimura, K. Nishimatsu and M. Ikeda for their help in running
the workshop smoothly. We are very grateful to Drs. T. N. Rengarajan,
S. K. Ghosh, and C. Pearson for their thorough checking of the English
in the manuscripts. We acknowledge the excellent help rendered by Dr.
T. Nakagawa and Ms. K. Nishimatsu in editing the proceedings.
