How much does it cost?
- How much does it cost?
The estimated cost for the overall project is approximately one hundred billion yen or one billion US dollars. Japan will bear the cost of 30 billion yen for the ACA system consisting of 16 high-precision antennas, three receiver bands, and ACA correlator, as well as the construction cost for the East-Asian ALMA-related facilities. Dividing 30 billion yen by the population of Japan, Japanese people are paying for the project about 30 yen per person in a year.
- What will ALMA bring to the public?
ALMA will bring us not only the scientific achievements related to the research of the origin of our planet, solar system, and the Galaxy, but also dreams especially for young generations who bear the future of societies based on advanced tecnologies. Recently, there is a tendency of moving away from science among young people, but ALMA may be able to change such movement. Furthermore, new technologies developed for ALMA are closely related to terahertz technology, information communication, signal processing and micromachining, which may have great impact on industry and our life. In a large-scale project such as ALMA, a wide variety of cutting-edge technology is developed including those that would not be developed by industries due to high risk. One good example of this is a device developed for the Nobeyama 45-m radio telescope, which is now being widely used in various electrical devices such as BS converter.
- Why is the Japanese participation necessary?
How can we share the dream of ALMA without playing active role in the project? Japan can provide leadership in this global project as a nation boasting the world's highest technology in the field of millimeter astronomy. Japanese technology is required for the realization of the submillimeter observation which is technically very difficult. By taking part in the ALMA project, the Japanese astronomers will further advance their high-level research.
