Asteroids, Comets, Meteors 2012
An international conference on small solar system bodies

16-20 May, 2012

Niigata, Japan

This is a first announcement of the Asteroids, Comets, Meteors (ACM) meeting which will be held in Japan. As you know, the serious trouble of the Fukushima Daiichi nuclear plant due to the East Japan Earthquake prohibited us to have ACM 2011 meeting as originally planned. We struggled to restart the organization, and succeeded to go as a renewed ACM 2012 meeting.

The Asteroids, Comets, Meteors (ACM) meeting is the premier international gathering of scientists who study all kinds of small bodies in our solar system. The ACM series began in 1983 in Uppsala, Sweden, as a means of bringing together different groups within the asteroid, comet, and meteor communities who do not often have the opportunity to interact. From this first ACM meeting, a regular conference began. The conference now takes place every three years, and it is the pre-eminent meeting for small-bodies research, with attendance usually in excess of 400. The 2012 ACM meeting will be the 11th in the series, and the first time in Asian Region. The members of SOC and LOC are listed at the web site.

The scope of presentations and discussion is broad, including all topics related to asteroids, comets, and meteors. ACM 2012 is expected to bring together experts on small-bodies studies from around the world. It will be the first meeting held after several significant and anticipated events, which include the return of "HAYABUSA" mission and the expected result of "Dawn", "EPOXI" and "STARDUST-NExT", as well as many others. ACM 2012 will highlight the research currently being conducted, and encourage discussion among researchers in various areas, and identify new avenues of research.
