[항공] Asteroid Deflection Research Initiative
1. 제 목 : Asteroid Deflection Research Initiative

3. 일 시 : 2008년 7월 9일 (수) 10:30 - 11:30
4. 장 소 : 서울대학교 정밀기계공동연구소(313동) 국제회의실(215호)
5. 내 용 : The technically challenging, astrodynamical problem of deflecting near-Earth objects (NEOs) to mitigate their probable impacts upon the Earth is discussed. A brief historical overview as well as key technical issues of such a complex NEO deflection problem is presented. Deflection technologies to be discussed include: nuclear standoff explosions, kinetic impactors, solar collectors, and slow-pull gravity tractors. This seminar also presents the research plan of the Asteroid Deflection Research Center (ADRC), which was recently established at Iowa State University in April 2008. The mission goal of the ADRC is: “Develop the science, engineering, and technology needed to reliably deflect or disrupt those large asteroids or comets that could collide with the Earth and cause a global climate change and/or the end of civilization.” 65 million years ago, a 10-km asteroid struck near the Yucatan Peninsula in Mexico and created the 170-km Chicxulub crater. Since 1990, most scientists believe that a global climate change caused by this asteroid impact may have caused the dinosaur extinction (as hypothesized by Luis Alvarez and Walter Alvarez in 1980). 50,000 years ago, a 50-m asteroid struck near Winslow, Arizona forming the 1-km wide Barringer Meteor Crater. 13,000 years ago, a 4-km comet may have exploded over North America causing extinction of woolly mammoths, global cooling and end of early human Clovis culture.
